General Information
This chapter describes the KFQSA module and the enclol!Jures into which
it can be installed.

1.1 KFQSA Module Overview
The KFQSA module is an adapter that allows Q-bus based host systems
like the MicroVAX system to communicate with Integrated Storage
Elements (lSEs) connected through the DSSI bus. ISEs are intelligent
storage peripherals such as disk and tape devices. In a OSSI single
host corafiguration, the KFQSA can connect up to seven ISEs to the host
comput.;er through the DSSI bus. In a DSSI VAXc1uater configuration with
a dua~ host configuration two KFQSAs can connect up to six ISEs to the
two hosts through the DSSI bus. In a OSSI VAXcluster configuration with
a three host configuration and three KFQSAs, the DSSI bus can connect
up to five ISEs.
Each DSSI ISE has its own controller, which contains the intelligence and
logic necessary to control data transfers over the DSSI bus. The KFQSA
contains the addressing logic required to make a connection between the
host and a requested ISE on the OSSI bus.
The KFQSA module is supported by the following operating systems and
diagnostic utilities:
•

VMS Version 5.1 or later l

•

ULTRIX-32m Version 3.0 or later

•

VAXELN Version 3.0 or latf~r

•

~ 'OM Version 3.0 or later

KFQSA DSSI VAXcluster (;OnfiguTations must use VMS Vel"8ion 5.1-1 or later.

1.2 BA440 System Enclosure
The BA440 pedestal enclosure (Figure 1-4) is used in VAX 4000 systems;
it is a free standing enclosUN for use in an office environment.

Figure 1-4 BA440 Enclosure

Mlo-OOtOn

The BA440 enclosure has a 12-slott quad-hOC,!ight backplane (Figure 1-5).
The backplane is a 21 x 16 inch assembly. The space between each
backplane slot varies. The backplanets printed circuit board is an eightlayer, two-sided etch board.
From right to left, the first five backplane slots are for the MS670
memories and the KA670 CPU, while the other seven slots are Q-bus
or CD bus slots.
Modules installed in the BA400 and BA200 series enclosures that connect
to external devices have bulkhf!ad handles with the 110 connector on the
handle. The handles replace the insert panels and internal cabling fOWld
in other enclosures. This design is easier to maintain since it eliminates
problems caused by faulty intemal cabling.

1.3 BA213 System Enclosure
The BA213 enclosure has a 12-slot, Q-bus backplane and two modular
power supplies. Figure 1-6 shows the BA213 enclosure.
The backplane implements the Q-bus on the AB rows of each slot. The
CD interconnect is implemented in all slots. MicroVAX systems use the
CD rows of slots 1 through 5 for their high-speed memory interconnect.

(~neral Information

Bus grant signal., pass through each installed module through the A
connectors of each slot. Figure 1-7 shows the bus grant routing for the
BA213 backplane. Use bus grant continuity cards (M904 7) in vacant
backplane slots to ensure bus continuity.
The BA213 encl08W"e holds up to four standard 5.25-inch storage devices.
Fixed disk drives face the rear of the enclosure, providing easy access
to the drive signal and power cables. Tape drives face the front of the
enclosure.
The m~or difference between the BA213 and other Ulicroaystem
enclosures is in the way you connect modules to external devices. Other
enclosures have an VO panel in the rear of the enclosure. The BA213
uses bulkhead handles or covers that fit over the front of the module.
Standard modules have bulkhead handles that are an integral part of the
module. Option modules, such as the KFQSA, have a bulkhead cover that
performs the same function, but are not attached to the module.
The bulkhead handles and covers fonn an electrical seal that complies
with FCC regulations for keeping radio frequency interference (RFI)
generated by the system inside the enclosure, and for keeping externally
generated RFI out of the enclosure. They also help guarantee proper
airflow through the system for module cooling.

1.4 BA123 System Enclosure
The BAl23 enclosure has a l3-slot, Q-bus backplane and holds up to five
6.26-inch storage devices. Figure 1-8 shows the BA123 enclosure.
The first 12 slots are for dual or quad-height modules. The CD rows of
slot 13 are for the signal distribution board. If needed, a second signal
distribution board can be installed in the AB rows of slot 13.
Figure 1-8 BA123 Enclosure

General Information 1-11

The backplane implements the Q-bus modules on the AB rows of each
slot. MicroVAX systems use the CD rows of slots 1 through 4 for their
high-speed memory interconnects. Figure 1-9 shows the bus grant
continuity path for the BAl23 backplane.
You can install the KFQSA and other Q-bus modules in slots 5 through
12. As a rule, if you install a dual-height module in either the AD rows or
the CD rows of a slot, you must install another dual-height module or a
bus grant continuity card in the other two rows of the slot. The exception
to this rule occurs when the dual-height module is installed in the last
occupied slot in the card cage.

The backplane implements the Q-bus module on the AB rows of each
slot. The CD rows of slots 1 through 3 form the MicroVAX memory
int-ereonnect. You should install only MS630 memory modules in the CD
n»ws of slots 2 and 3. You caD install any dual-height modules in the AB
rows of slots 2 and 3. Slot 1 is reserved for the CPU module. Figure 1-11
shows the bus grant continuity path for the BA23 backpla,ne.
You cal' install the KFQSA and other Q-bus modules in slots 4 through
8. As a ruJe, if you install a dual· height module in either the AD rows or
the CD rows of a slot, you must install 8nother dual-height module or a
bus grant continuity card in the other two rows of the slot. The exceptio"
to this rule occurs when the dual-height module is installed in the last
occupied slot in the card cage.

1-14 General Infonnation

1.6 DSSI VAXcluster Configurations
nssl ISEs have a capability built into their finn ware that allows the ISE
to maintain simultaneous connections with more than one host system.
A DSSI VAXduster configuration uses nSSI cables as the interconnect.
Q-bus modulee for VAX or MicroVAX systems interface to DSSI cables
by means of a DSSI adapter, such as a KFQSA module. Some adapter
modules are embedded in the processor module.
As many as 8 DSSI nodes may use the same intelTonnect. A DSSI node
is any device to which DSSI transports infonnatiofl and for which DSSI
therefore needs an address, including ISEs and KFQSA modules on VAX
or MicroVAX systems.

In a DSSI VAXcluster configuration, the host systems (and possibly an
expansion cabinet such as the R215F) are connected together through
an external nBSI cable. Each system is a boot server in a Local Area
VAXclueter configuration. The host systems may share a common system
disk ISE or may have independent system disk ISEe. Each BYstem bas
direct and equal access to the common system disk ISE through its
KFQSA module, and to any other ISE in either enclosure.
Figure 1-12, Figure 1-13, and F'igure 1-14 are examples of DSSI
VAX ...luster configurations using the KFQSA module.
The benefits of a KFQSA-based DSSI VAXcluster configurations are:
•

VAXcluster features, such as shared data across systems and satellite
nodes

•

Simplified system management due to ~l shared system disk (see the
following page)

Shared batch and print queueR

•

Higher system availability

Planning the System Installation
It is important to carefully plan the system installation before putting any
new modules into the system. Thi!'! involves checking the power and bWl
load requirements, and checking to make sure you have everything yo~
need to make the configuration work.

Fill out a configuration worksheet before proceeding with the installation
A configuration worksheet lets you track the parameters that limit system
configuration such as space, power requirements. and bus loads.
Figure 3-1, Figure 3-2, Figure 3-3, and Figure 3-4 are examples of
a configuration worksheets for the BA440, BA213, BAIZ3. and BA23
enclosures, respectively. Table 3-1 lists power and bus load data for all
cUlTently supported modules and storage devices
Complete the configur'ation worksheet by perfonning the followintJ steps:
1. List al1 devices already installed in the aystem.
2.

List all devices you plan to install in the system.

Fill in the power and bus load data from Table 3-1 for each device you
have listed.

4. Add the columns and make sure the totals are ",thm rhp limIt'"
specified for the enclosure

KFQSA S~/itches
Before installing the KFQSA. you must choose a control and status
register address (CSR) that will allow the host to access the adapter. A
four-position DIP switchpack is provided for this purpose. Figure 4-1
shows the location of the switchpack. Table 4-1 explains the function of
each switch.
In most cases you should use one of the dedicated CSR addresses. 8S this
allows a programming addrpqg to be selected without the possibility of
conflict with other modules in the system. 10 do this. set the switches &8
follows:
•

OFF

With Switch 1 in the OFF position (toward the number 1"
the other switchefl are ignored and CSR addresBes are read
from the configuration table. After the configuration table
has been programmed (Chapter 7l, the system should be
powered down and this switch ahould be set to the OFF
position, where it should remain unless the configuration
table il!l corrupted and needl!l to he reprogrammed.

Putting Switch 1 in the ON position enables the selection
of a CSR address for programming the configuration table.
This is the switch poeition for the initial installation. The
CSR addreas Belected for programming depends on the
position of the other three switches.

OFF

Putting Switch 2 in the OFF position enables the selection
of one of four CSR addresses that have been dedicated
for programming the KFQSA. Table 4-2 show! how the
remaining two switches are used to select one of these
addresses. These addreoses should be used only for initially
accessing the KFQSA to program the EEROM.

Putting Switch 2 in the ON position enables the selection
of one of four addres8e8 normally reserved for MSCP or
TMSCP devices. Table 4-3 shows how the remaining two
switches are used to 88lect one of these addresses. I
When SwitcheD 1 and 2 are ON and OFF. respectively.
these switches are used to select one of four dedicated CSR
addresseR (Table 4-2).
When Switches 1 and 3 us both ON. these switches are
used to lIelen either a disk (MSCP) addr888 or a tape
(TMSCP) addres8 (Table 4-31.

IAvoid uaing these adcireellM!8 at dUll time; they may c"nflict with other moou)PFI in the

Installation Procedures 5-17

5.5 Installing DSSI VAXcluster Configurations
A DSSI VAXcluster configul'ation is a highly integrated organization
of VAX computers. As members of a DSSI VAXcluster, computers can
share processing resources, disks and queues under single VMS security
and management software, and can boot and fail independently. DSSI
VAXc1uster configurations provide a high level of processing and data
ac('~ss.

5.5.1 Types of DSSI Bus Configurations
DBSI Single Boat Configuration uses DSSI bus as the interconned.
Q-bus or MicroVAX systems interlace to a DSSI bus by means of a
DBSI adapter (KFQSA). As many as 8 DSSI nodes may use the same
interconnect. A DSSI node is any device to which DSSI transports
information, and therefore needs an address. In a DSSI single host
configuration, the node number for the KFQSA is usually 7.
Two-System DSSI VAXcluster configurations use two host systems
to share RF-series ISEs. The maximum number of ISEs that can be
accessed by the hosts is 6. The ISEs can be located within each host,
within an expander enclosure, or both. A two-ho:'t systeJT'. provides
high disk availability for critical applications. In a two-~YBtem DSSI
VAXcluster configuration, the node numbers for the I01QSAs are 7 and 6.
Three-Syatem nssl VAXcluater configurations allow the common DSSI
bus to share all the reSOUt'ces among the three hosts. In a three host
configuration, the middle node (KFQSA6), all the internal terminators are
removed from the board (Figure 4-1). The unterminated KFQSA adapter
has both an IN and OUT bulkhead connector that allows DSSI bus signals
to travel through the adapter to the other hosts. The maximum number
of ISEs to be accessed in this configuration is 5.

5-18 Installation Procedures

5.6 Rules for Installing DSSI VAXcluster Systems
There are some restrictions that apply to DSSI VAXcluster systems using
the KFQSA module:
•

Adapter modules connected to the same DSSI bus when running VMS
Version 5.3-1 and earlier must be of the same type.

•

The host systems must be in close proximity to each othl-T, due to
DSSI bus cable length limitations (measured from end terminator

to end terminator). The maximum distance in a three-system
configuration is 82 feet in a computer room environment and 65
feet in an office environment.
•

All enclosures in a DSSI VAXcluster configuration must be powered

from the same ac feed. That is, they must either be powered from
the same ac circuit, or if they are powered from different ac circuits,
then those circuits must not power any other equipment, must share a
Bingle ground point, and must have a dedicated ground wire between
the outlet and the single point ground.
•

'Thnninators must reside at the ends of the nSS} bus when configured
for multiple hosts.

•

All systems must be using VMS Version 5.1-1 or later.

•

The maximum of 5 enclosures can be configured on a DSSI
VAXcluster; for example, two VAX or MicroVAX systems and three
expansion enclosures or three VAX systems and two expansion
enclosures.

•

Each ISE on a DSSi VAXcluster configuration must appear with the
Bame device name and address on all host nodes.

•

A maximum of 3 Q-bus VAX or MicroVAX systems can be present on
a DSS} VAXcluster configuration. The middle KFQSA adapter board
is untenninated.

•

Each node on a single DSSI interconnect must have a unique DSSI 10
number, which allows the software to communicate with the storage
devices. Numbers lDust be between 0 and 7; these numbers are
permanently associated with the hardware. Node numbers may be
l"t'peated on different DSSI interconnects that are connected to the
Bame host systems.

Installation Procedures &-19

•

The length of any single cable between the connectors on nSSI
VAXcluster buses is 25 feet.
NOTE

Due to limitatioD8 in the Micl'OVAX n boot ROMI, two MicroVAX n
systems in • DSSI VAXclultar configuration cannot automatically
boot from a common system disk I8E. If a common system disk is
used, each node in the DSSI VAXclusler confiJUl"ation must boot
from a different root (SYSO, SYSl). But the MicroVAX n system
can only boot .u~tical1y from SYSO. It is recommended that
each MicroVAX D system have ita own locally connected system
disk (such .s an RDlW or RA82). When a common system disk ISE
is a requirement, one MicroVAX D system may automatically boot
from 8YSO but the other must be booted manually from SY81.
When a MicroVAX n system is in a DSSI VAXcluater configuration
with a MicroVAX 3000 or higher serieslystem, the MicroVAX n
system should boot from SYSO and the MicroVAX 3000 or higher
series system should boot from an alternate root.
If you are inJtalling more than one system into a nSSI VAXcluster

configuration, install each system individually and test it to make sure it
is working correctly. When you complete the installation and testing of
each system, then reconfigure each system using the procedures in either
Chapter 6 or Chapter 7.
This includes:
•

Detennining correct CSR addresses for all modules in each system

•

Repl'Ogramming the KFQSA configuration table for the new
configuration

•

Reconfiguring any modules whose CSR addresses changed as a result
of the new ('onfiguration

•

Changing the allocation class of the ISEs so they are the same as both
hosts

After reconfiguring, remove the tenninators and connect thf' DSSI
extension cables between the hosts or expansion cabinets.

Programming the DSSI Subsystem Using
Console Commands
The KFQSA configuration table may be programmed in two ways, either
by using console commands or by using the MicroVAX Diagnostic Monitor
(MDM). Using the console commands is the recommended choice if your
system has this «:apability.
'1b find out if you can use console commandf!l for programming thf:
configuration table, reinitialize the system and read the microcode
version that is displayed on the console. If the microcode version is
4.1 or later, the console commands may be used for programming the
KFQSA configuration table.
If your system does not have this capability, refer to Chapter 7 for the
MDM procedure. If your system does have console commands, perform
the procedure deecribed in this chapter.

To find the console commands available, type HELP at the console prompt
(»». 1b program the KFQSA configuration table, use these commands.

6.1 Determining CSR Addresses
Each module in a Q-bus based !\yetem must use a set of unique Q-bus
addres8as and interrupt vectors. One of these, generally the lowest of
the set, is known as the CSR address. The KFQSA emulates an SSP
controllerl for each ISE connected, and presents a separate CSR address
for each emulated controller. You must program the KFQSA with a
correctly chosen CSR address for every ISE on the DSSI hus. Interrupt

SSP controllers also include the RQDX3, KDA50, RRD50, RQC25, TQK50, and
TQK70 controllers. All such porte are identical, and are operated by the same

PUDRIVER.
6-1

&-2 Programming the DSSI Subsystem Using Console Commands

vectors for the KFQSA (and other SSP controllers) are programmed
automatically by the operating system.
Unlike moat other Q--bus controllers, KFQSA CSR addresses are not set
with switches or jumpers. They are contained in nonvolatile memory on
the KFQSA module in the form of a configuration table. To access the
configuration table, you must set the switches on the KFQSA to select
one of the dedicated addresses shown in Table 4-2. You must ensure the
KFQSA is terminated either through on-board SIP terminators or through
external nSSI terminators.
Before programming the configuration table, first determine what the
CSR address~s should be for all devices on the system. Calculating CSR
addresses is a complex procedure because some devices are asBi~ned
floating addresses. Floating addresses vary with each module installed on
the system.
At the console prompt (»», type CONFIGURE.
The CONFIGURE console command is similar to the VMS SYSGEN
CONFIGURE utility. It permits the user to enter Q-bus device names,
and then generates a table of recommended Q-bus CSR addresses.
After entering the command, the syntem prompts you for a device and
a number. 'lb find which responses are valid, type HELP. The system

6.3 Programming the KFQSA Module for a DSSI
VAXcluster Configuration
This section describes how to program the KFQSA module when setting
up a DSSI VAXcluster configuration. This configuration will always
involve two to three KFQSA adapters.
This procedure has three objectives:

1. 1b configure all KFQSA modules so that they can access all of the
ISEa connected on the DSSI bus
2. 1b give each KFQSA a unique DSSI node ID

3. To configure the KFQSAs and ISEs 80 that each ISE has a device
name that is unique and universal throughmlt the DSSI VAXcluster
configuration
NOTE
All ayllteml should be powered up and displaying the conlole
prompt. The DSSI cables between the hOlt .y.teml Ihould not be
connected at thil time.

Figure 6-1 and Figure S-2 are typical block diagrams of DBSI VAXcluster
configurations. Using these examples, perfonn the following procedure on
System A.
1. Display the current addresses and devices as follows:

NOTE
Make hardcopy printouts of the displaYI or write down the
information obtained in this .tep. It will be needed later in
thil procedure.
B.

Type SHOW UQSSP for a display of all SSP controllers currently
on the system. This display lists the ~bU8 address (octal I and
port name of each SSP device on the system. An example of this
display is shown in Section 6.2.

Configuring the DSSI Subsystem Using
MOM Commands
This chao _ discusses how to assign CSR addresses as a preparation for
programming the KFQSA configuration table.

7.1 Determining CSR Addresses
Each module in a Q-bus based system must use a set of unique Q-bus
addresses and interrupt vectors. One of these. generally the lowest of the
set, is known as the CSR address.

7.1.1 Overview
The KFQSA emulates an SSP controller l for each connected ISE.
Therefore, you must program the KFQSA with a correctly chosen
CSR address for every ISE on the DSSI bus. Interrupt vectors for the
KFQSA (and other SSP controllers) are programmed automatically by the
operating system.
Unlike most other Q-bus controllers. KfQSA CSR addresses are not set
with switches or jumpers. They are contained in nonvolatile memory on
the KFQSA module in the form of a configuration table The configuration
table is programmed using an MDM program, as explain~d in S€'('tlon 7.2.
NOTE

KFQSA modules installed in Micro~AX 3000 and 4000 series
systems are more easily configured using the procedures given
in Chapter 8.

SSP controllers a180 include the RQDX3, 1IDA50. RRD50. RQC25, TQK50, and
TQK70. All such ports are identical and are operated by the 8ame PUDRIVER.

7-2 Configuring the DSSI Subsystem Using MOM Commands

NOTe

1b acce.. the conflguration table you must set the switches on
the KFQSA to select one of the dedicated addresses shown in
Table 4-2.
Before you probJ'8m the configuration table you must first detennine
what the CSR addresses are going to be for all devices on the system.
Calculating CBR addresses is a complex procedurf because some devices
are assigned floating addresses. Floating addresses vary depending on
which modules are installed on the system.
Use an MDM utility called IOADDBES to determine what the CSR
addresses and interrupt vectors should be for all devices on the system.
This utility is supported in MDM Version 3.0, Release 125 or later. The
next section describes hew to use IOADDRES. You should already have a
working knowledge of MDM. If you need detailed infonnation on how to
use MDM refer to the MDM User's Guide (AA-FM7A-DM>.

7.1.2 Using MOM to Determine CSR Addresses
1. BootMDM.
2. Enter the correct date and time.
3. Select the command line mode (Option 2). The system issues a caution
and instructs you to enter 1 for the menu mode or 2 to proceed with
the command line mode.
4.

Enter 2 and press IReturn I. The system diRplays the MDM» prompt.

5. Type the command Run IOADDRES. The system responds with:
Configuring utility for IOADDRES

The display prompts you to enter a number for each class of devices it
supports. Table 7-1 shows the abbreviations for supported devices.
6. At each quers. enter the number of devices from that class that are
installed in th& sysjm. If no devices of that class are instCll1ed in the
system, press Rsturn (the default value of zero is entered,
After you have responded to all queries, the system display~ a
summary of the classes and the number of devices in each class.
lt then displays a table containing the fonowing infonnation.

7.3 Programming the KFQSA for a DSSI VAXcluster
Configuration
This section describes how to program the KFQSA modules in a DSSI
VAXc1uster.
NOTE

In a DSSI VAXcluster environment, a three-system configuration's
llUUdmum length of cable(s) (measured from the two end KFQSAB)
ill 82 feet in a computer room environment and 85 feet in an oftice

onvironment.
The maximum number of enclosures in a DBSI VAXcluster
coDillJW"8tion is 5. For example, two VAX or MicroVAX systems
and three ezpaneion enclosures.
Figure 7-1 is a diagram of a typical two-system DSSI VAXcluster
application. which will be used as an example during this procedure.
NOTE

The DSSI cable(s) should be connected between the two
systems, and power to both systems should be turned on before
programming.
Perform the following procedure on System A:
1. Determine the con-ect CSR address for each dp,vice and module in the
system by performing the steps outlined in Sect:Jn 7.1.2. Make sure
to include all devices residing in the system and all ISEs connected to
the DSSI bus.

Do not skip any numbers.
3. Reprogram any modules whose CSR addresses were bumped as a
result of including the ISEs.
4. Assign a DSSI node ID of7 to the KFQSA in System A
5.

Repeat the proce<jure in Steps 1 through 3 for System B ASSlgrt a
DSSI node ID of ~ to the KFQSA in this system.

NOTE

Make sure that the ISEs have been assigned the same DSSI
node IDs ~.D both KFQSA conftguration tables.

Configuring the DSSI Subsystem Using MOM Commands 1-11

CAUTION

Make sure that the device name of each ISE ia identical on
both nodes. Failure to do 80 can result in a partitioned cluster,
and co-uequently data corruption.
6. Replace any nece8s 'Y DBSI unit ID plugs in the Operator Control
Panel for each ISE to make them match the DBSI node IDa assigned
to the ISEs for a DBSI VAXcluater configuration.
7. Boot one node and note the device names reported by VMS Boftware.

8. Shut down the node and boot the other one. Note the device names to
ascertain that both systems see the same set of device names.

7.4 Setting the ISE Allocation Class
This section describes how to change the ISE allocation class. In a DBSI
VAXcluster configuration. you must assign the same nonzero allocation
class to all host systems and to all ISEs on the DBSI bus.
NOTE

DSSIISEs are shipped with the allocation class set to zero.
Change the allocation class by using the following procedure. This
procedure only needs to be performed from one of the host systems.
1. Determine the correct allocation class for the ISEs according to the
rules on clustering.
NOTE
In a DBSI VAXcluater couftguration, the same allocation clasa
must be aaBiped to allayslema and to all connected ISE.. This
allocation claas must be different from that of other systems or
HSC in a cluster.

Diagnostics
This chaI ter describes the diagnostics for testing the KFQSA module and
the conne\ ted DSSI ISEs.

8.1 Power- On Self·Test Diagnostics
The KFQSA module has a power-on self·test (POST) that performs a
comprehensive set of logic tests whenever power is applied to the module,
or when the host issues a Q-bus BUS INIT. POST tests about 95 percent
of the KFQSA module'~ logic and executes in less than ten seconds. It
executes whether or not any other DSSI devices are connected to the
KFQSA module.
The KFQSA module has one green and five red LEDs mounted on the
edge of the board <Figure S-l). When power is applied, all five LEDs
light. The red LEDs go out as POST routines are executed successfully.
After the successful completion of all POST routines only the green LED
remains lit.
NOTE

In some cases. the red LEDs go out 80 quickly that you may think
they never came on. If the green LED is on when you look at the
module after applying power, POST ran successfully.

8-1

8-2 Diagnostics

figure 8-1 KFQSA MODULE LEOS Location

UoOI1D-TlD

8.2 LED Error Codes
The two types of errors detected by POST are fatal errors and nonfatal
errors. Fatal errors cause the adapter to abort service and walt for
reinitialization. Nonfatal errors are recoverable.
A POST failure also causes an error code to be sent to the SA registers.
When the error is fatal. the microprocessors are forced into an infinite
loop sequence that can only be broken by receiving an INIT from the host.
If a nonfatal error is detected, the green LED remains lit and the red
LEOs display an error code for approximately ten seconds. Table 8-1
shows the POST LED nonfatal etTOr codes.
If a fatal error is detected, the green LED goes out and a sequence of red
LEDs remains lit. Table 8-2 shows the POST LED fatal error codes.

KFQSA Troubleshooting
The tools used to diagnose the KFQSA module and connected ISEs are:
•

POST, power-on self test. described in Section 8.1.

•

NAKFA, KFQSA module's functional diagnostic, described in
Section 8.3 or the SET HOSTIDUP console command described in
Section 8.4.

Generally, KFQSA module failures fall into one of two categories:
•

The system fails to boot because of a KFQSA module problem.

•

The system boots, but the KFQSA module fails.

In the case of a boot failure, verify the installation again using the
procedures outlined in Chapter 5. Then verify the configuration using the
procedures outlined in Chapter 6 or Chapter 7. Most boot problems are
caused by incorrectly setting up the device configuration or addressing.
If the system boots but the KFQSA module fails, reapply power to cause
POST to run, and cl".eck for the presence of a LED error code.
Always perform a visual inspection of the KFQSA module and al1
connected nssl devices before troubleshooting. Some KFQSA module
problems that can be solved by visual inspection arE" listed in TahlE" 9-1.
