Preface
Product Description
The DECsystem 5900 computer system is designed for server applications,
including file servers, compute servers, and network servers. It is a midrange
system that uses a modular approach, based on industry standard 47.5 cm (19 in)
rackmount components.
DECsystem 5900 servers use a high-performance single-board computer based on
the MIPS R3000A processor (KN03) or the MIPS R4400 processor (KN05). The
DECsystem 5900 cabinet contains a power controller, a single CPU drawer, and
up to four additional mass storage drawers. There can be a second optional CPU
drawer, and only up to three mass storage drawers.

Document Description
This guide describes the DECsystem 5900 server configurations, explains console
commands used to operate the system, describes the system options that are
available, and explains troubleshooting procedures.
Any service or upgrades to the DECsystem 5900 system must be done by a
Digital Service representative or a qualified self-maintenance customer.

Audience
The DECsystem 5900 Owner’s Guide is for system managers or technical users
who are responsible for operating the system on a daily basis.

1.3 DECsystem 5900 System Power Controller
The DECsystem 5900 single-phase ac power controller is located at the bottom
of the system cabinet, as shown in Figure 1–2. Each drawer in the cabinet plugs
into the system power controller, which provides a single point of system power
control. The power controller provides power to the CPU and mass storage
drawers and is normally configured to remotely (from the front of the system)
power the system off/on. The non-U.S. version has a detachable power cable (see
Table 1–6).

Operating the DECsystem 5900 System
This chapter contains the following sections explaining how to prepare and
operate the system, including descriptions of the console commands:
•

Preparing Your DECsystem 5900

•

SCSI ID Switch/Jumper Settings

•

Turning On the DECsystem 5900 Drawers

•

Shutting Down the System

•

Console Commands

•

Environment Variables

•

Console Command Error Messages

2.1 Preparing Your DECsystem 5900
Your order should be shipped with the options and other devices you ordered
already installed. It is recommended that you check your system to ensure
that this has been done. If an item is missing, contact your Digital Services
representative.
Before powering up your system, ensure that all options, cables, console
terminals, and other peripherals are properly connected. Make certain that the
system is in a location which follows all site environment guidelines. Refer to the
DECsystem 5900 Installation Guide and DECsystem 5900 Site Preparation guide
for further details.

Operating the DECsystem 5900 System 2–1

2.2 SCSI ID Switch/Jumper Settings
The Small Computer Systems Interface, or SCSI, is an interface designed for
connecting drives and other peripheral devices to computer systems. Each device
has a set of switches or jumpers that are set for a specific SCSI ID.
Up to seven SCSI devices can share a SCSI controller. Each of the seven SCSI
devices are identified by a number from 0 to 6, called SCSI ID. Each SCSI
controller has a unique ID.
Note
No devices should use SCSI ID 7, as this is reserved for the SCSI
controller.

Digital sets each SCSI device to a default SCSI ID setting before the equipment
leaves the factory.
SCSI default settings are listed in Table 2–1. The settings listed give optimal
performance on most systems.

2–2 Operating the DECsystem 5900 System

CPU SCSI adapter

First removable device

Boot device or first device

Remaining devices, in order

1,2,3,4,6

Remaining removable devices

6,4,3,2,1

Note
Digital recommends that you use Digital-supplied cables for
interconnecting SCSI devices. Digital also recommends that you
power all units on the SCSI controller from a common power source.
The proper operation of any SCSI controller that uses cable assemblies
not supplied by Digital, or not configured in accordance with Digital’s
recommendations, is not guaranteed.
The maximum length of each SCSI bus (up to four SCSI buses per
cabinet) must not exceed 6 meters (19.8 feet). In calculating SCSI bus
length, the external SCSI cabling and the SCSI cabling within the
drive(s) must be considered. Exceeeding this length may cause data
integrity problems.

2.3 Turning On the DECsystem 5900 Drawers
It is assumed that the system has already been plugged in and connected to the
console terminal. In addition, the following is also assumed:
•

The front and rear cabinet doors are open.

•

The circuit breaker on the system power controller (lower rear of the cabinet)
is in the on position (up).

•

The Remote/Manual toggle switch, located on the back of the system power
controller (lower rear of the cabinet) is in the remote (up) position.

•

Power switches, located on the rear panels, are on for each mass storage
drawer.

Operating the DECsystem 5900 System 2–3

Once your system is properly set, turn on the system power switch, located on the
upper front panel of the CPU drawer (slot 3). If there is a second optional CPU
in slot 2, turn on the system power switch on the upper front panel of that CPU
drawer.
Close the front and rear cabinet doors.

2.3.1 Power-Up Self-Tests
Note
For proper loading and booting procedures, see the Guide to Installing
ULTRIX. If your system does not automatically boot, refer to Section 2.5.5
in this chapter.

When you turn on the system power, the system automatically runs a power-up
self-test script. The test names display on the console terminal as they perform.
Results of the tests are shown in hexadecimal values on the pair of four LEDs at
the back of the CPU drawer. These tests do not test the drives in the drawers.
Addresses and functions of the installed devices can be verified when running
extended tests.
See Chapter 3 for further details on running the power-up self-tests.
Refer to the DECsystem 5900 Service Guide for extended testing of mass storage
devices, I/O options, and troubleshooting procedures.

2.4 Shutting Down the System
To shut down the system, refer to Section 2.5.3 in this chapter.
Caution
Do not turn off, halt, or restart the system without first notifying the
network group members and bringing down ULTRIX in an orderly
fashion.

2–4 Operating the DECsystem 5900 System

2.5 Console Commands
This section describes the various DECsystem 5900 console commands and how
to use them. Specifically explained are:
•

The rules to follow when you type console commands.

•

Terms commonly used in this discussion of console commands.

•

The command format and purpose of each console command.

•

Possible console command error messages.

2.5.1 Console and Operating Modes
Your two DECsystem 5900 modes are: console mode and operating mode. When
your system is in console mode, you are using the setup and testing firmware that
is built into the system. When your system is in operating mode, you are using
your system software.
This section explains how to use the ULTRIX operating system in console mode.
Your system software manuals explain how to use the system in operating mode.

2.5.2 Using Console Mode
The system starts in console mode and stays in that mode until you start
your system software. While you are in console mode, you can use the console
commands, which are the commands of the built-in setup and testing software.
The prompt for console mode is >>.
Use console mode and the console commands for such tasks as:
•

Running system self-tests

•

Displaying system hardware configurations

•

Setting system environment variables

•

Booting (starting) the operating system

2.5.3 To Enter Console Mode
To enter console mode, do one of the following:
•

If the system is powered off, power it up to achieve console mode, assuming
the autoboot is not set.

•

If the ULTRIX operating system is up, notify users and perform an orderly
shutdown by typing the following command etc/shutdown -h now (-h is time
and time can be minutes, hour:min, or now) at the ULTRIX prompt and press
Return .

Operating the DECsystem 5900 System 2–5

2.5.4 Console Prompts: Privileged and Nonprivileged
When you are in console mode, the system displays one of these two prompts on
your console screen: >> or R>.
•

The privileged console prompt (>>) means that you can execute all console
commands at the console prompt.

•

The nonprivileged console prompt (R>) indicates that someone has set up
a password requirement to restrict access to the console prompt. At the
nonprivileged console prompt, the user can use only the boot and password
console commands until the correct password is entered.
To change to the privileged console prompt (>>), type passwd and press
Return . Then enter the console password and press Return again. If you do
not know the password, contact your system manager or your Digital Services
representative. See Section 2.5.19 for more information on the passwd
command.

2.5.5 Booting the DECsystem 5900 System
To enter operating mode, boot (start) the operating system in any of these ways:
•

At the console prompt, type boot path, where path is the path specification
for the operating system. For example:
>> boot 3/rz0 vmunix -a

•

If you have previously set the boot path with the setenv bootpath
environment variable:
At the console prompt, type boot and press Return .

•

If you have previously set the boot path with the boot environment variable,
and you have set the haltaction environment variable to b:
Turn on your system. The operating system boots automatically.

2.5.6 Rules for Typing Console Commands
You can use all console commands when the system terminal displays the console
prompt (>>). A restricted console prompt (R>) indicates that someone has set up a
password requirement. You can use only the boot and passwd commands at the
restricted console prompt until you enter the correct password. Then the normal
console prompt (>>) appears.
To use a console command, type the command as shown, add appropriate options
and arguments, and press Return .

2–6 Operating the DECsystem 5900 System

Follow these rules:
•

Type uppercase and lowercase letters exactly as they appear in the guide.
The DECsystem 5900 console, like the ULTRIX operating system, recognizes
the difference between uppercase and lowercase letters.

•

Press Return after typing a command.

•

Use these handy key combinations:
Ctrl-s freezes the screen display.
Ctrl-q releases a frozen screen display.
Ctrl-c aborts a command.
Ctrl-u erases a partially typed command line.
DEL erases the last character typed.

•

To type a hexadecimal number, precede the number with 0x (zero x). To
type an octal number, precede the number with 0 (zero). To type a decimal
number, do not precede the number with any leading 0s (zeros).

•

To use the Ctrl commands, hold down the Ctrl key while you type the letter of
the command. For example, to use Ctrl-s , hold down Ctrl while you type s.

2.5.7 Conventions
•

Letters in boldface type like this should be typed exactly as they appear.

•

Words in italic type like this OR LIKE THIS are options or arguments for the
commands. You must replace them with the appropriate information. For
example, the script command has a scriptname argument. When you type
the command, you replace scriptname with the name of the script you are
creating.

•

Options are read by the console programs. Arguments are read by the system
software.

•

When options and arguments are shown in brackets, you should use them
only if they are appropriate. When they are not in brackets, you must use
them all the time. For example, the printenv command is shown like this:
printenv [env]
Because [env] is enclosed in brackets, you should use it only when it is
appropriate, which in this case is when you want to display the setting of one
environment variable.

Operating the DECsystem 5900 System 2–7

The script command is shown like this:
script scriptname
Because scriptname is not shown in brackets, you must use it in every script
command.
Do not enclose options and arguments in brackets when you type them. The
brackets are just a way of showing you when to use them.
•

When an argument is followed by an ellipsis, you can use more than one
argument with the command.

2.5.8 Console Command Functions, Options, and Syntax

setenv EVN STR
sh [-belvS] [SCRPT] [ARG...]
t [-l] #/STR [ARG...]
unsetenv EVN
The following sections describe each console command in detail. Note that the
command descriptions do not always use the format that appears in the help
menu.

2.5.9 ?
>>? [command]
The ? command displays the help menu. If you enter the name of a specific
command after the ?, the screen displays the help message for that command
only.

2.5.10 boot
>>boot [OPTIONS] [#/path]
[argument...]
Options are:
-a

Use a multiuser bootstrap.

-n

Load but do not execute path program.

-z number

Wait for number seconds, then boot.

The boot command loads and executes the program specified by #/path, where
# is the slot number of the device that you are booting from, and path is the file
specification of the program. The -a argument boots for a multiuser environment;
to perform a single-user boot, enter the boot command without the -a argument.
The -n option suppresses execution of the program after it is loaded. The -z option
Operating the DECsystem 5900 System 2–9

causes the system to wait before booting. When you enter the command with no
options, path, or argument, it uses the options, path, and argument in the boot
environment variable.
The following example of the boot command uses the options and arguments that
you set in the boot environment variable:
boot
The following command boots from a tape drive in base slot 3 (tz is the device
code of the drive, and 5 is its SCSI ID number):
boot 3/tz5
The following command boots from the network that is connected to your system
through the built-in Ethernet controller:
boot 3/mop
The following command performs a multiuser boot (-a) using the file vmunix on
an external drive (rz1) in base slot 3 (rz1 is the device code and SCSI ID for the
drive):
boot 3/rz1 vmunix -a

2.5.11 cat
>>cat #/scriptname
The cat command displays the contents of the script specified by scriptname. The
# option indicates the number of the slot where the script is stored.

2.5.12 cnfg
>>cnfg [#]
The cnfg command displays important information about the configuration of
your system. The information tells you what kind of hardware is in the system
and connected to it. If you type a slot number for #, the command displays
configuration information for that slot. Otherwise, it displays general information
for all the slots.
The following example shows the display for a cnfg command in which the specific
slot number was not specified. This information shows what kind of modules
are in the base system slot (base slot 3) and in the option slots. The system has
option modules in slots 2 and 1. The numbers in black circles correspond to the
descriptions that follow.

The -S option fetches the contents of each address in the address range count
times. The screen displays only the final value in each range.

2.5.15 erl
>>erl [-c]
The erl command displays the log of console error messages (see Section 2.7).
The system records console error messages in a special error log buffer, and the
erl command displays the contents of this buffer. If you specify -c, the buffer is
cleared. The system stops recording error messages when the buffer is full and
resumes when the buffer is cleared.

2.5.16 go
>>go [address]
The go command transfers control of the system to the specified address. If you
do not specify an address, go uses the execution address returned by the last boot
-n command. If the boot -n command has not been executed and no address is
specified, the system ignores the go command.

2.5.17 init
>>init [#] [argument...]
The init command initializes module hardware. If you specify a slot number (#),
the command initializes the modules in that slot only.
Arguments are specific to each module.

2.5.18 ls
>>ls [#]
The ls (list) command displays a list of the files in a module ROM. If you do not
specify a slot number (#), the command lists the files for all modules.

2.5.19 passwd
>>passwd [OPTIONS]
Options can be:
-s

Set a new console password.

-c

Clear the console password.

Use the passwd command to enter, set, or clear your console password.

Operating the DECsystem 5900 System 2–15

The console password keeps unauthorized people from using the console
commands on your system. You do not need to use the password if security
is not an issue in your workplace.
When you first set up your system, you do not need a console password. The only
way that a console password can be required is if you choose to start using one. 1
To enter a console password, type passwd -s and press Return . The system
displays a prompt (pwd:) asking you to type the password that you want to use.
Type a word with at least six characters. You can use letters and numbers; the
system recognizes the difference between uppercase and lowercase letters.
The system displays the pwd: prompt twice. Type the same password each time.
For the sake of security, the screen does not display what you type, so type
something that is easy to remember.
To enable the restricted console, type passwd and then press Return . When the

pwd: prompt appears, the restricted console looks like this:
R>

At this prompt, you can only boot your system software or enter your console
password.
•

Boot your system software. Type boot and press Return . This is the only
boot command that you can use. It has no options or arguments. It uses the
values that you set in the boot environment variable (see Section 2.6). If you
have not set the variable, the command does not work.

•

Enter your console password. Type passwd and press Return . Then type your
console password at the pwd: prompt. For the sake of security, the screen
does not display what you type.

After you enter your console password, the prompt changes to the standard
console prompt (>>). You can now use all the console commands that are
described in this chapter.
To stop using your console password, type passwd -c at the standard console
prompt and press Return . Afterwards, you will have unrestricted access to the
console commands.
Clearing a Forgotten Password
If the system is in restricted mode and you forget the password, you
must clear the contents of the nonvolatile RAM (NVR), which contains

the DECsystem 5900 Service Guide or contact your Digital Services
representative.

2.5.20 printenv
>>printenv [env]
The printenv command displays the values of environment variables. If you
specify the name of an environment variable, the command displays the value of
only that variable. See Section 2.6 for more information.

2.5.21 restart
>>restart
The restart command attempts to restart the system software. This command
relies on a restart facility that you have to enable in the system software.

2.5.22 script
>>script scriptname
The script command allows you to write a short temporary script at the system
console. A script is a miniprogram. After you write the script, you can run it with
the sh command, or you can type the name (scriptname) of the script by itself at
the console prompt to execute the script. This command is commonly used during
testing of the system by Digital Services representatives.
To write a script, type script followed by a name for the script and press Return .
Then write the script line by line. When you are done, go to a new line and press
Return .

2.5.23 setenv
>>setenv env value
The setenv command sets the value of an environment variable. Note that you
must enclose the command in double quotation marks if value contains blank
spaces. See Section 2.6 for more information.

2.5.24 sh
>>sh [OPTIONS] [#/scriptname]
[argument...]
Options can be:
-e

Exit on error.

-b

Branch to script.

-v

Verbose; echo to console.

-S

Suppress script-not-found errors.

-l

Execute in a loop. (This option is the letter ‘‘el,’’ not the number one.)

The sh, or shell, command activates, or runs, a script. Replace # with the slot
number of the module that contains the script.
If you specify a script name for the scriptname option, the script is used as the
input. Otherwise, what you type at the console is the input, and a subshell is
created. When you run a shell script, environment variable 0 is set to the script
name, 1 is set to the first argument in the script, 2 is set to the second argument,
and so on.
The -e option directs the shell to exit when an error occurs. Normally, the shell
ignores errors. The -b option executes the script specified by scriptname instead
of creating a subshell. The -v option causes the script to be echoed to the console
when it is executed. The default setting is no echo. The -S option suppresses any
error message if the script is not found and causes the sh command to return
a status that indicates success. The -1 option causes a script to be executed
continuously until a system reset occurs or you press Ctrl-c .

2.5.25 t
>>t [OPTIONS] #/testname

Chooses the system console. You normally do not set this variable. Setting
this variable to s selects the terminal connected to the system console port
(see Figure 1–4). Setting this variable to any value other than s causes
the console to automatically select the console device using the following
algorithm:

1. Select the graphics adapter in the lowest-numbered TURBOchannel
slot.

2. If there are no graphics adapters in the system, use the system console
port.

If more than one terminal is connected to the system unit, the terminal in
the lowest-numbered slot is the system console.

1. Check to make sure you specified the correct slot number
for the missing device in the cnfg command.

2. Make sure the drawer in which the missing drive is located
is turned on and is connected to an active power source
(switch LED on).

3. Make sure the missing device has a unique SCSI ID from
0 to 6.

4. Try the cnfg command again. If the device is still missing,
call your Digital Services representative.

You cannot connect to
your network, and you
know the system and
network software are
functioning.

1. Shut down your system software and turn off the system.
2. Make sure the Ethernet connectors on the system unit are
attached correctly. If you are using adapters to connect
ThinWire or twisted-pair Ethernet cable to your system,
check those connectors, too.

3. Turn on the system.

3.2 Running Power-Up Self-Tests
The server runs a power-up self-test when you turn on the system power. The
console and diagnostic LEDs report any errors the power-up self-test detects. To
find the corrective action for any error codes the power-up self-test reports, refer
to the DECsystem 5900 Service Guide.
Note
If the console displays the message PDE3: x, where x represents an option
module slot number, the system may contain incompatible ROM chips.
Contact your Digital Services representative.

Troubleshooting Tools and Error Messages 3–3

You can specify a quick or thorough power-up self-test script to run when the
system powers up.
•

The quick test script is a limited script that minimizes the time until the
system boots.

•

The thorough script runs an extensive check of system hardware. The
thorough power-up self-test script is most useful for Digital Services
representative troubleshooting.

To select a power-up self-test script, use the setenv command to set the testaction
environment variable. Type setenv testaction (q | t) and press Return .
•

Specify q to select the quick test.

•

•

?TFL indicates that an error occurred.

•

slot represents the slot number of the module that reported the error.

•

test represents the individual test that failed.

•

code represents a code that indicates which part of the test failed.

•

description represents a possible message that describes the failure.

•

messages, refer to the DECsystem 5900 Service Guide.

3.4 ULTRIX–32 Exerciser and uerf Command Summary
This section contains a summary of ULTRIX–32 exerciser and uerf commands to
help you troubleshoot and diagnose DECsystem 5900 errors.
See the following documents for detailed information on the commands:
•

ULTRIX–32 Guide to System Exercisers

•

ULTRIX–32 Guide to the Error Logger System

3–4 Troubleshooting Tools and Error Messages

3.4.1 On-Line ULTRIX Exerciser
The ULTRIX exercisers perform functional system and device testing. The
exercisers are run in single- or multiuser mode from an account with root
privileges.
The exercisers log status information in LOG files. Normal device errors are
handled by the error log and uerf. You can run each of the exercisers in the
background by ending each command line with an &. This allows many (the
same or different) exercisers to be run concurrently, enhancing your ability to
perform system testing.
To run the exercisers, your current directory must be the field account. To
terminate the exercisers, enter Ctrl/C if the job is in the foreground, or kill -15
pid if in the background. When you run an exerciser in the background, pid if
the job is displayed when the command is envoked.
A time stamp entry is made in the system error log each time you stop or start
an exerciser. Use the uerf option -r 350 to include these in an error report. All
the system exercisers, except netx, have the -o option. The -o option allows you to
specify a file where diagnostic output is saved when the exerciser terminates.

3.4.2 Exercising More Than One Part of the System
You can run more than one exerciser at the same time. Keep in mind, however,
that the more processes you have running, the slower the system performs.
Before exercising the system extensively, make sure there are no other users on
the system.
To exercise more than one part of the system simultaneously, use the syscript
maintenance command. The syscript command asks you which exercisers you
want to run, how long you want to run each exerciser, and how many exercisers
you want to run at one time. The syscript command allows you to exercise a
device, a subsystem, or the entire system.
You can start each exerciser by using either of the following methods:
•

Manually, by specifying the time parameter (-t option) and by placing each
command in the background before executing the next command

•

By typing the syscript command as follows:

# syscript
Once the syscript command is running, answer the questions displayed on the
console. The syscript command then executes the individual exercisers and
creates a file called testsuite, which contains all the answers you entered. You
can reexecute the commands in the testsuite file by entering the following, which

Troubleshooting Tools and Error Messages 3–5

causes testsuite to execute using the original commands and parameters that you
specified:

# sh testsuite

3.4.3 Communications Exerciser (Asynchronous Serial Lines)

Number of memx processes to spawn. Maximum is 20. Default is 20.

Usage
The memory exerciser is restricted by available swap space. Errors like out of
memory generally indicate swap space was used up. If you have more physical
memory than swap space, you may see this problem. If so, reduce the number
of spawned processes and/or the size of memory you are testing. Running the
memory exerciser can also cause other users to have the same memory problem.

3.5 Using Error Logs
The system records events and errors in the ULTRIX error logs. Use the error
logs to verify proper system and device subsystem operations.
Note
The ULTRIX error logs are not the same as the test error logs that appear
when you use the erl console command. The test error log is a record of
errors reported by tests run in console mode.

The following paragraphs describe ULTRIX error log formats and error log parts
useful in troubleshooting.

3.5.1 Examining Error Logs
You must be in ULTRIX to examine error logs. At the ULTRIX prompt, type
/etc/uerf -R | more and press Return . A full display of error log entries appears
on the console.
The first part of each error log describes the type of error and system conditions
in effect when the error occurred. The last part of each log provides specific
information about the error and its location.
The first part of all error logs is similar to this:
----- EVENT INFORMATION ----EVENT CLASS

The maximum approved cable length is 300 cm (10 ft), as follows:
Cat1 V.24 300 cm (10 ft) for extension BC13P-10

C.1.1 Approvals for Digital Circuits
The KN05 is approved for direct connection to a particular digital circuit. This
approval includes interconnection cable with mating connectors conforming to
BS6623 part 1 and part 4.
If the product is connected to the service with anything other than its own
approved cables, then those cables must benefit from the relevant general
approval and/or conform with any other applicable requirements.
Caution
Ports J5, J9, J10, J11, J12, J17, J9, J31, J49, J51, E1, and E3 do not
provide sufficient isolation to satisfy the requirements of the relevant
parts of standard BS6301. Any product connected to these ports must
meet one of the following conditions:
•

Be covered by OFTEL’s General Approval NS/G/1234/J/100003. All
products supplied by Digital comply with this General Approval.

•

Have been approved to the relevant parts of standard BS6301.

•

Have previously been evaluated against the British Telecom (Post
Office) Technical Guide 2 or 26 and given permission to attach.

Other usage will invalidate any approval given to this apparatus.
Interconnection directly, or by way of other apparatus, of ports marked
by the safety warning label with other ports that are marked or not so
marked, may produce hazardous conditions on the network. Seek advice
from a competent engineer before making any such connection.

C.1.2 Host Independent Approvals
The KN05 is approved only for installation in an approved host with approved
attachments. For approval, the host and host attachments must be one of the
following:
•

Type-approved (meaning the equipment is built exactly like the models that
were originally approved).

C–2 United Kingdom Regulatory Information

•

If the equipment was supplied after March 1, 1989, it must be marked with or
supplied with a statement that the host is supplied under General Approval
Number NS/G/1234/J/100003.

Except at the edge connector which plugs into the host’s expansion slot, clearance
and creepage distances of Xmm and Ymm, as listed in Table C–2, must be
maintained between the KN05 and other parts of the host, including any other
expansion cards fitted.

The creepage distances apply when installed in a normal office environment.
The creepage distances shown in parentheses apply where the local environment
within the host computer is subject to conductive pollution or dry non-conductive
pollution which could become conductive due to condensation. These distances
can be checked by measuring between the adjacent parts.
If in doubt, advice should be obtained from a competent telecom safety
engineer. Failure to install the DECsystem 5900 server in accordance with
these instructions will invalidate the approval.

C.1.3 Host Power Rating
The user must insure that the power drawn by the KN05 together with the host
and other auxiliary apparatus drawing power from the host, is within the rating
of the host power supply.
Digital has designed all permutations of the host configuration to operate within
the limits of the host power rating.
Table C–3 contains the module power rating.

Table C–4 applies to all ac line input conditions per Table C–1. Individual output
regulation specifications are valid at all other specified output loadings at the
output connector.
Noise and ripple are peak to peak to be measured as follows:
•

Input voltages within specified operating ranges.

•

Loads on all outputs within specified ranges.

•

Measurement taken with Tektronix P6046 probe and an oscilloscope
(minimum 100 MHz bandwith).

•

Loads to be resistive.

•

Measurement taken at load side of output connector using ‘‘Bendix’’ type
connectors (recommended) with very short leads. The measurements will
be taken with a 10uf tantalum capacitor terminated in both minimum and
maximum resistive loads.

•

This measurement is for use during qualification during testing.

C.1.3.1 Dynamic Load Regulation
Dynamic load regulation for +5.1 V shall be 100 mV peak and 2 ms maximum.
Dynamic load regulation for +12.1 V shall be 240 mV peak and 2 ms maximum.
This load regulation is expressed as the peak deviation from the steady-state
dc-output voltage, and the time required for the output voltage to settle back to
within 0.5% of its new steady-state value after an instantaneous change in the
output current, with all other factors held constant. The instantaneous voltage
shall not exceed the total regulation limit.

United Kingdom Regulatory Information C–5

C.1.3.2 DI/DT Load Steps
DI/DT load steps for +5.1 V shall be 0.06 A/uS for a 15 A step.
DI/DT load step for +12.1 V shall be 0.2 A/uS for 0.6 A to 1.0 A.
The rate of change of lead current which may be stepped while keeping the output
voltages in regulation. Current steps are either positive or negative going and
shall be within the limits specified. The time period between steps shall not be
less than three times the settling time specified. The time period between steps
shall not be less than three times the settling time specified in Section C.1.3.1.
