Troubleshooting

Selftest Failures

Chassis codes are the key to debugging selftest errors. If a failure is found during selftest,

chassis codes are displayed in the LCD. The procedure for using these codes to debug a

failure is as follows:

1. Using Table 3-2, which starts on the next page, find the chassis code listed on the LCD.

2. To get additional information about failures from the Boot Console Handler, use the

Service Menu’s

pim

pdt

, and

ChassisCodes

commands.

In the following table, the FRU column shows messages printed on the LCD that refer to

system FRUs. Only

FLT

codes have FRUs associated with them. Some

WRN

codes are also

device specific, especially to IODC calls; for example,

8xxx

codes.

TST

and

INI

codes do not

necessarily correspond to any FRU. All codes are listed in numeric order.

NOTE

Because the B2000 workstation is a single-board system, references to the

I/O BD

(I/O board) in chassis codes displayed on the LCD and listed in Table

3-2 are actually references to the

SYS BD

(system board).
