16-28 Troubleshooting startup problems

System fails to boot completely

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Troubleshooting stage

9 bootup failure

To troubleshoot stage 9 bootup failure, follow these steps.

Troubleshooting stage

10 bootup failure

This stage normally takes approximately five minutes.

However, on a multi-node system, if a remote node is having

problems booting up, then this stage can take as long as

20 minutes. Follow these steps.

Step Action

1 Check the terminal output during this stage.

2 If there is indication that SEERs may be lost, power down the

system and power it back up to reset the system.

3 If the system has multiple nodes and the output indicates that

some of the non-prime nodes are not responding, check the

power supply for those nodes. See “Preliminary action” on

page 16-18 and “Testing the DCEPS” on page 16-21 (DC

system) or “Testing the CEPS” on page 16-23 (AC system).

4 Power the system down, then power it back up to reset the

system. If the boot still fails at the same point, replace the

Enhanced MMP40 (or MMP40) cards of the affected nodes.

5 If the problem occurs on all the remote nodes, perform the

system bus diagnostics (“Performing system bus diagnostics”

on page 16-31).

Step Action

1 Check the SEER output from the printer for problems with

remote nodes.

2 If one or more remote nodes (but not all) are having problems,

power down and up to reset the system.

Note:

If the problem is occurring on all nodes, follow

“Performing system bus diagnostics” on page 16-31.

3 If the problem persists, replace the Enhanced MMP40

(or MMP40) cards of the affected nodes.
