Troubleshooting and Build-Up Procedures
Introduction
This document is intended to assist in the troubleshooting of an rp54xx series system exhibiting one or more
of the following repetitive symptoms:
•
The system will not power on or remain powered on. In the power-on mode, the green power LED on the
system front panel should be on and the cooling fans are all receiving DC power and are spinning at
normal speeds.
•
The system will not power on to standby mode (power switch off). In the standby mode the green power
LED on the system front panel and on the platform monitor board will be flashing.
•
The system will not begin self-test execution. In this case, the system will successfully power on and
remain powered but the system will fail to enter its self-test execution.
•
The system will power on and enter the power-on self-test execution but will not pass self-test and/or boot
to the boot console handler (BCH).
Initial Troubleshooting Steps
Prior to starting troubleshooting, please note:
•
Service Note A5191A-05 documents a DC power-on issue that may provide assistance. It provides DC
power troubleshooting procedures and illustrations. The troubleshooting procedures in this Service Note
will be utilized in this document.
•
Service Note A5191A-28 documents a problem with the DC power converter cable that may cause a
self-test hang that may not be resolved by the troubleshooting procedures in this document.
•
The guardian service processor (GSP) should be functional and available whenever the system
successfully powers up to standby mode. In standby mode DC power provides "housekeeping" voltages to
the GSP. It is highly recommended that the GSP be utilized to assist in troubleshooting whenever
available.
Begin Troubleshooting
It can be difficult to troubleshoot an rp54xx series system that will not power on, initiate self-test, or boot to
BCH. In some cases the GSP will provide meaningful events in the error logs. These error log entries may
point to a failure in a critical component (e.g. multiple fan failures, a bad power supply, etc.) causing the
