IBM pSeries 630 6C4 Service Manual page 85

Symptom
You have a blank display on the operator panel. Other
LEDs on the operator panel are off.
You have an 8-digit error code displayed
The system stops with an 8-digit error code displayed
when booting.
The system stops with a 4-digit number displayed that
does not begin with 0 or 2.
System stops with a 3-digit number displayed (see below for 888 sequence)
The system stops with a 3-digit error code.
Symptom: Hardware Management Console (HMC) cannot be used to manage a managed system, or the connection
to the managed system is failing.
Action: If the managed system is operating normally (no error codes or other symptoms), the HMC might have a
problem, or the connection to the managed system might be damaged or incorrectly cabled. Do the following:
1. Check the connections (serial cable) between the HMC and the managed system. Correct any cabling errors if
found. If another serial cable is available, connect it in place of the existing cable and refresh the HMC graphical
user interface. You may have to wait up to 30 seconds for the managed system to reconnect.
2. Verify that any connected HMC is connected to the managed system by checking the Management Environment
of the HMC.
Note: The managed system must have power connected and the system running, or waiting for a power-on
instruction (the OK prompt is in the operator panel.) If the managed system does not appear in the Navigation
area of the HMC Management Environment, then the HMC or the connection to the managed system might be
failing.
3. Go to the "Entry MAP" in the IBM Hardware Management Console for pSeries Maintenance Guide, order number
SA38-0603.
4. If you cannot fix the problem using the HMC tests in the IBM Hardware Management Console for pSeries
Maintenance Guide, there might be a problem with the CEC backplane; replace the CEC backplane.
Symptom: Hardware management console (HMC) cannot call out using the attached modem and the customer's
telephone line.
Action: If the managed system is operating normally (no error codes or other symptoms), the HMC might have a
problem, or the connection to the modem and telephone line may have a problem. Do the following:
1. Check the connections between the HMC and the modem and telephone line. Correct any cabling errors if found.
2. Go to the Entry MAP in the IBM Hardware Management Console for pSeries Maintenance Guide, order number
SA38-0603.

Hardware Management Console (HMC) Problem
Action
Go to "MAP 1520: Power" on page 105.
Look up the error code in the table in "Checkpoint and
Error Code Index" on page 213.
Look up the error code in the table in "Checkpoint and
Error Code Index" on page 213.
Go to "Checkpoint and Error Code Index" on page 213.
If you do not find the error code there, go to the Fast
Path MAP in the RS/6000 Eserver pSeries Diagnostic
Information for Multiple Bus Systems.
Add 101- to the left of the three digits to create an SRN.
Go to the RS/6000 Eserver pSeries Diagnostic
Information for Multiple Bus Systems.
If there is a location code displayed under the 3-digit error
code, then look at the location to see if it matches the
failing component that the SRN pointed to. If they do not
match, perform the action from RS/6000 Eserver
pSeries Diagnostic Information for Multiple Bus Systems
first. If the problem still exists, then replace the failing
component from that location code.
