Hardware Overview

The DECserver 300 is an Ethernet terminal server that allows devices (terminals,
printers etc.) to communicate on an Ethernet LAN.

WARNING
Ethernet installations may extend to thousands of
meters and couple hundreds of separate items of

equipment. To prevent hazardous voltages appearing on the installation, it is important that all

the equipment be part of a common equipotential
system as defined in IEC publications 364-4-41

clauses 413.1.2 and 413.1.6. Where it is required
to couple equipment outside of the main equipotential bonded area via Ethernet, then optical
repeaters or other such galvanically isolated meas-

ures must be employed. If in doubt please refer to
Digital Equipment Corporation for advice.
ADVARSEL

BV SR T E N,

The DECserver 300 hardware supports the EIA-423-A electrical interface standard. EIA-423-A is compatible with the EIA-232-D interface but supports longer
cabling runs and higher signalling speeds. In addition, EIA~-423-A minimizes damage to computing equipment caused by electrical overstress (EOS) and electrostatic
discharges (ESD). EOS and ESD are the most common causes of communications
equipment failure.

The DECserver 300 system allows any combination of 16 attached devices access to
computer systems on a LAN via the port device connectors. Each device is connected to the computer systems and to their resources. The DECserver 300 system
supports 16 asynchronous serial data communication channels and has both ThinWire and standard Ethernet interfaces.

Overview

1-9

The DECst .ver 300 system supports devices that require data-leads-only for operation. It } as two additional signals, DSR and DTR, which may be used as follows:
=

DSR 'ogout — Logs out an attached device on power-down

DCSR/DTR — Flow control for printers or other attached devices

DSR — Status signal check for printers
NOTE

The DECserver 300 does not support connections
to wide-area networks via modems, or connec-

tions to non-LAT hosts. Users requiring these capabilities should use the DECserver 200/MC
which

provides asynchronous

Software Requirements

The software requirements for installing and operating the DECserver 300 are as
follows:

DECserver 300 distribution software — Installed on each DECserver 300
system load host.

DECnet Phase IV software — Installed on each DECserver 300 system
load host (not required for ULTRIX systems).

LAT service node software — Installed on all LAT service nodes that communicate with DECserver 300s and their devices.

You must install the distribution software on a load host that runs DECnet Phase 1V
software. The distribution software includes a server image file that is down-line
loaded to a DECserver 300. The load host down-line loads the server image whenever required, and provides the server image to any number of servers. The server
image, running on the DECserver 300, constitutes the server software that enables
the server to perform its functions. The server software implements the LAT architecture on the DECserver 300.
The service node software suppor.s the LAT architecture and must be installed on

each service node. The LAT software is packaged with each of the following operating systems:

VMS operating systems

ULTRIX~32 operating system

All software must be installed and verified before you can operate the server.

For more information, see the DECserver 300 Software Product Description that
applies to each specific operating system.

Site Verification

This chapter provides information for verifying that the preselected installation site
meets the server’s physical, environmental, electrical, and network cabling requirements.

The instructions in this chapter assume that the customer has completed the following site preparation requirements:

3.1

A server installation site is identified.

An appropriate ac power source is within 1.8 meters (6 feet) of the server.

The network connection is arranged to a preinstalled Ethernet device.

Verifying Hardware and Cable Requirements
The server can operate in an office environment and in a standard equipment rack

located in a computer room or satellite equipment room. Regardless of where the

server will be installed, you must verify that all of the requirements in this section
are met before beginning the installation.

3.1.1

The maximum cable segment length must not exceed 185 meters

(606 feet).

-4

DECserver 300 Hardware Installation/Owner’'s Guide

There must be a 50-ohm terminator at each end of the cable segment un-

less the cable ends in a DEMPR or DESPR. (Both these devices have
bult-in SU-ohm terminators).
There must be only one ground cable per segment.

There must be at least 0.5 meter (19 inches) between T-connectors.

The maximum number of stations, between terminators, must not
exceed 30.

ThinWire cable segments must never be configured in a loop.
ThinWire cable segments must never have any branch segments.

3.2

Preinstallation Checks
Befare beginning the server installation, use the following checklist to make sure
that the site preparation is complete.

3.2.1

Hardware Checks

Arrangements have been made to connect the server Ethernet port to an

Ethernet interface device. For Standard Ethernet, the device can be a
DELNI network concenirator or an Ethernet transceiver. For ThinWire
Ethernet, the device can be a DEMPR or a DESPR.
The Ethernet interface device is installed and the required cabling is in
place, tested, and tagged.

The wall/partition mounting bracket kit or rack mount Kit is installed (if
required) as described in the kit documentation.

Cables of appropriate length are available for connecting the server to the
Ethernet interface device.

The devices (terminals, printers, personal computers, and hosts) are ready
to be connected.

One terminal (asynchronous, EIA-423-A or EIA-232-D compatible) is
available for hardware testing and system verification.
3.2.2 Software Checks

The DECserver 300 Identification Card was filled out (as described in Section 4.1) and given to the system manager.

The system manager

installed or will install the server software on the

load host.

Running Self-Test

Plugging in the server power cord applies power directly to the server and starts
self-test. The seven-segment display and diagnostic dot (decimal point) supply
diagnostic and status information. Figure 4-10 shows the seven-segment display
and diagnostic

dot.

Table 4-1

When the server power cord is plugged in, the seven-segment display shows an “8”,

and the diagnostic dot is on, for approximately 0.5 seconds as a display check. The
diagnostic dot is turned off as self-test starts and the display counts down from “F”
through “5"as each block of tests is executed . If a fatal error is detected, testing
stops and the DECserver display flashes the code corresponding to the failing test.

If a nonfatal error is detected testing continues and the diagnostic dot blinks. (See

Chapter 5§ for what action to take).
NOTE

There is one exception to this sequence. If the

server fails the Ethernet subsystem external loopback test, the display stops at “9” and the diagnostic dot blinks. The “9” on the display does not

blink.

4-12

DECserver 300 Hardware Instaliation/Owner's Guide

When the server passes self-test, it attempts to load the server software from the

host and will display the appropriate code(s) (see Table 4-1). At any time after
self-test execution, power down the server, disconnect the T-connector and terminators, and continue with the installation.

Connecting to the ThinWire Ethernet LAN
To connect to a ThinWire Ethernet LAN,

insert the T-connector into the BNC

connector at the rear of the server and turn the barrel of the connector clockwise to
lock (see Figure 4-15).
NOTE
Figure 4-15 shows the T-connector terminated

using a 50—-ohm terminator. The 50-ohm terminator is replaced by a cable if the server is not at
the end of a cable segment. The cable segment

must be terminated by

50-ohm terminators at

both ends unless a DEMPR or a DESPR is used.
Where a cable segment is terminated in a DEMPR

or a DESPR at one end only the opposite end
needs to have a 50-ohm terminator (see Appen-

dix C — Cabling Strategy — for further details).

What to Do If You Have Problems

This chapter helps you identify and correct problems that may be encountered
during the initial installation of the DECserver 300 hardware. The troubleshooting
procedures are for diagnosing and correcting hardware-related problems only.
NOTE
Notify the server manager if the troubleshooting

procedures indicate the problem is software re-

lated or if the procedures do not correct the problem. Additional troubleshooting information is
provided in the DECserver 300 Problem Solving
manual and

DECserver 300 Management man-

ual.

5.1

Problem Indicators
The seven-segment display, located at the rear of the server, indicates the status of

the server and is used for diagnosing server problems. The diagnostic dot of the
display also provides diagnostic information.

5.2

Diagnosing Server Problems
Compare the state of the seven-segment display and the diagnostic dot with those

shown in Table 5-1 and go to the section indicated for information on corrective
action.

NOTE

On power-up,

the seven-segment display will

show an “8” and the diagnostic dot will be “on”
for about 0.5 seconds. Allow about 2 minutes to

elapse before determining the state of the display.

Problem

Power is not reaching the DECserver 300 hardware.
Correction: Ensure that the voltage select switch is set to the correct voltage for
your country (see Section 4.4).

Correction: Secure the power cable at the server and at the wall outlet and check
the fuse in the power cable plug (if applicable).

Correction: Check the wall outlet using another appliance or light, or plug the
server power cord into another outlet

If power is not available at the wall outlet,

check the wall outlet’s circuit breuker.

Correction: Check if the server circuit breaker has tripped. If it has, disconnect the
power, press the white button to reset the breaker (see Figure 1-3), and reconnect
the power. If the circuit breaker trips more than once, notify the server manager
that the server must be returned to Digital Equipment Corporation for repair. (Re-

fer to the DECserver 300 Problem Solving manual for information about returning
the unit to Digital.)

Correction: Check for a defective server power cable and replace.

5-2

DECserver 300 Hardware Installation/Owner's Guide

Problem

The DECserver 300 hardware is defective.

Correction: Notify the server manager that the server must be returned to Digital
for repair or replacement. (Refer to the DECserver 300 Problem Solving manual
for information about returning the unit to Digital.)

Diagnostic Dot Off/'Seven-Segment Display Flashing

Problem

A hardware error occurred that makes the DECserver 300 server inoperative.

Correction: There is no corrective procedure for this problem. Notify the server
manager that the server must be returned to Digital for repair or replacement. (Refer to the DECserver 300 Problem Solving manual for information about returning
the unit to Digital.)

5.5

Diagnostic Dot Blinking
If the diagnostic dot is blinking after power-up it indicates that the server has a
nonfatal problem de‘ected during self-test. To isolate the problem, connect a console terminal to port 1 of the server. The primary problem indicator in this case is
the error message that appears on the console terminal.
To isolate and diagnose the problem, do the following:
i.

Connect a console terminal to port 1 of the server, then power up the ter-

|2]

minal.

Configure the terminul to operate with a speed of 9600 bits per second
and with a character size of 8 bits (no parity). (Refer to the specific terminal user’s guide if you need help setting up the terminal parameters.)

Unplug the server power cord at the wall outlet, then reinsert it.

Read the error message that appears on the terminal display. (If r » mes-

sage appears on the terminal display, refer to Section 5.5.8.)
The following sections list the error messages that occur in conjunction with diagnostic dot blinking. Locate the section that describes the displayed error message

and follow the recommended corrective action.

Correction: If the above actions do not correct the problem, verify the server external Ethernet circuit with a loopback connector. If the Ethernet loopback connector (12-22196-02)

is available do the following (If this loopback connector is

not avatlable switch to ThinWire and refer to 5.5.7. This will check the server
Ethernet as far as the selector switch on the standard Ethernet circuit):

Disconnect the transceiver cable from the server.
Plug the Ethernet loopback connector into the Ethernet connector on the
server.

Initialize the server by pressing

[CTRL/P] on your console terminal, or by

unplugging the server power cord from the wall outlet and then reinserting
i

Wait 2 minutes for the diagnostic test to complete, then observe the status
of the diagnostic dot.

If the diagnostic dot continues to blink and the error message reappears after the self-test, the server is faulty and must be returned to
Digital for repair or for replacement. Notify the server manager.

If the diagnostic dot is on continuously, go to step 5 to isolate and to

determine the faulty unit.
NOTE
When using the Ethernet loopback connector to

troubleshoot the DECserver 300 hardware, if the
self-test detects no errors, the server attempts to

down-line load the server image. Since the server
is disconnected from the network, the down-line
load fails and the server responds by displaying

the appropiate code (see Appendix F).
Unplug the Ethernet loopback connector from the Ethernet connector on
the server.

Reconnect the transceiver cable to the Ethernet connector on the server

Disconnect the other end of the transceiver cable.
Plug the Ethernet loopback connector into the transceiver cable.

Initialize the server by pressing [(CTRL/P| on your console terminal, or by
unplugging the server power cord from the wall outlet and then reinserting
it.

If the diagnostic dot continues to blink, the transceiver cable is faulty
and must be replaced.

What to Do If You Have Problems

5-7

NOTE

When using the T-piece and 50-ohm terminators

to troubleshoot the DECserver 300, if the self-test
detects no errors, the server attempts to downline load the server image. Since the server is disconnected from the network, the down-line load
fails and the server displays the appropiate code

(see Appendix F).

Unplug the 50-ohm terminator and reconnect the ThinWire coaxial cable
to the server T-piece.

Disconnect the other end of the ThinWire coaxial cable and terminate it
with a 50-ohm terminator.

Initialize the server by pressing (CTRL/P| on your console terminal, or by
unplugging the server power cord from the wall outlet and then reinserting
it.

If the diagnostic uot continues to blink, the transceiver cable is faulty
and must be replaced.

If the diagnostic is on continuously the cable is working. If there is a

second cable return to step 4 and check it also. If both cables are
found to be working, the fault lies with some other device or cable on
the segment. Notify the server manager so that arrangements can be
made for repair or for replacement of the faulty device or cable.

Cabling Strategies

C.1

Server-to-Network Connection
The DECserver 300 hardware can be connected to either a standard Ethernet, ora
ThinWire Ethernet, local area network. The following sections describe common
strategies that are used.

C.i1

Standard Ethernet Connecuon

A transceiver cable connects the server to the standard Ethernet network (see
Figure C-1). The transceiver cable can be connected to any of the following:
Another transceiver cable section. This cable can be secured in an
Etherjack junction box.

A DELNI local area interconnect.

A transceiver on a standard Ethernet coaxial cable for Digital Equipment
Corporation baseband networks or a DECOM for Digital Equipment Cor-

poration broadband networks.

A standard rack cabinet in a Satellite Equipment Room (SER) for DECconnect systems. See the DECconnect System Planning and Configuration
Guide for installing the DECserver 300 DECconnect systems.
NOTE

The DECserver 300 is compatible with digital
baseband and broadband Ethernet products and
with Ethernet and IEEE R02.3 specifications.

C.1.2 ThinWire Ethernet Connection

A ThinWire coaxial cable connects the server to the system. The server can be
connected as follows:

As part of a stand-alone ThinWire Ethernet coaxial cable segment

As part of a DEMPR or DESPR ThinWire Ethernet coaxial cable segment

Figure C~2 shows servers connected as part of a ThinWire Ethernet segment.

NOTE

A ThinWire segment must begin and end in a
S0-ohm terminator as shown in Figure C-2.

Figure ' -3 shows servers connected as part of DEMPR ThinWire Ethernet segment

NOTE

The DEMPR and DESPR terminate the line internally in 50 ohms so that it is not necessary to use a

S0-ohm terminator.
However, all unused lines
a 50-ohm terminator
have
must
on the DEMPR
installed as shown in Figure C-4.

Further information on ThinWire Ethernet installation may be found in DECconnect System Planning and Configuration Guide.

Server-to-Device Connection
The server can be connected to devices directly or by using a patch panel (in a
rack-mount configuration). The following sections describe both methods.

C.2.1 Connecting to Server Directly

1f the device has an MMJ connector, you connect the server using BC16E-xx cable
directly .
If the device has a 25-pin D-connector,
put a 25-pin adapter
(H8571-A) on the device end of the BC16E-xx cable to make the connection (see
Figure C-6). If the device uses a 9-pin D-connector, use a 9-pin adapter
(H&571-B). The adapters available are listed below:

H8571-A — MMJ to 25-pin D-connector. female, filtered, with jack
screws. Used for connecting to terminal communication ports.

H8571-B — MMIJ to 9-pin D-connector, female, filtered, with jack
screws. Used for connecting to 9-pin printer ports.
H8571-C — MMJ to 25-pin D-connector, male, unfiltered, with mounting

hex nuts. Used for connecting from MMJ ports to an EIA-232 connection.

H8571-D — MMJ to 25-pin D-connector, male, filtered, with jack
SCrews.

Transceiver Cables
8NE3x-xx transceiver cable — Available in FEP versions, for use in return air
conduits, and in PVC versions, for use in nonenvironmental airspaces. The large
diameter of this cable results in a lower signal cable loss per length of cable than the
smaller diameter office transceiver cable. Two styles of connectors are available: a

straight connector and a right angle connector.
The following cables are available:
»

BNE3A-xx PVC, straight-connector transceiver cable

BNE3B-xx PVC, right-angle connector transceiver cable

BNE3C-xx FEP, straight-connector transceiver cable

BNE3D-xx FEP, right-angle connector transceiver cable

BNE3H-xx PVC, straight-connector, 802.3-compliant transceiver cable

BNE3K-xx PVC, right-angle connector, 802.3-compliant transceiver cable

BNE3L-xx FEP,

BNE3M-xx FEP, right-angle connector, 802.3-compliant transceiver cable

straight-connector, 802.3~compliant transceiver cable

The above cables are available in lengths of 5 meters (16.4 feet), 10 meters (32.8
feet), 20 meters (65.6 feet), and 40 meters (131.2 feet).
BNE4x-xx office transceiver cable — Available in PVC versions for use in non-en-

vironmental airspaces. The smaller diameter of this cable makes it ideal for use in

office environments, however the smaller diameter results in a cable signal loss that
is four times greater than that of BNE3x-xx transceiver cables. Two styles of con-

nectors are available: a straight connector and a right angle connector.
The following cables are available:
=

BNE4A-xx PVC,

straight~connector transceiver cable

BNE4B-xx PVC, right-angle connector transceiver cable

BNE4C-xx PVC, straight-connector, 802.3-compliant transceiver cable

BNE4D-xx PVC, right-angle connector, 802.3-compliant transceiver cable

The preceding cables are available in lengths of 2 meters (6.6 feet) and 5 meters
(16.4 feet).

Down-Line Load

This appendix explains how th< server attempts to locate a load host and down-line
load the server software image.

F.1 Down-Line Load
The down-line load process has three phases as shown below:

Load Request — The server transmits load requests in an attempt to locate
a load host. The seven-segment display shows a “4” during load request.

Load Backoff — The server refrains from transmitting load requests for a
period of time when previous requests have not resulted in a successful
load. This is to reduce the burden on the available load hosts. The backoff period starts at 4 seconds and doubles each time, up to a maximum of

5 minutes. The seven-segment display shows a “3" during load backoff.
=

Image Transfer — Loading of image after load host is located. The sevensegment display shows a “2” during image transfer.
Note

The backoff state is only entered if the server has
been unable to load a software image. Normally,
the server goes from the “Load Request” state to
the “Image Transfer” state.
The

DECserver

300

down-line

load

process

supports

both

Ethernet

and

1SO8802-2/3 (IEEE 802.2/802.3) onthe LAN. The “Load Request” state is comprised of two parts, one of which uses ISO8802 format, and the other Ethernet
format. When the server makes a load request, it first attempts to load using

ISO8802 format. If unsuccessful, the server then attempts to load using Ethernet
format. If the server is unsuccessful in both formats it enters the backoff state. At
the end of the backoff state .he server enters the load request state and starts again.

F-1

Figure F-1 shows the loading process when the server is unable to locate a load
host. The diagram shows the use of the two datalink formats, the changes between
the load request and backoff states as a function of time, and the corresponding
seven-segment display codes.
