Purpose

This document addresses temperature warnings or errors on an individual component (board, repeater, etc) in Sun Fire [TM] 3800, 4800, 4810, E4900, 6800, E6900 and Sun Fire [TM] v1280, E2900, and Netra [TM] 1280, 1290 systems.
This document covers situations where the system is powered on, but warnings or errors related to temperature exist in the configuration on a single implicated device.

Note: If you have multiple devices in the same chassis reporting temperature warnings, see Document 1013119.1: Troubleshooting temperatur warnings on multiple components within a Sun Fire [TM] Serengeti or LightWeight8 system

Troubleshooting Steps

Symptoms:

A System Board, I/O Board, Repeater, or System Controller reports unusually high or low temperature warnings or messages.
Fan Tray(s) may be marked Failed in showenvironment output from the System Controller.
A domain may be unable to be powered on and booted or it could be completely unaffected by the issues.
The System Controller should be accessible (able to login).

Steps to Follow
Please validate that each troubleshooting step below is true for your environment.

The steps will provide instructions or a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.

1. Verify external power is present for the system.

Confirm systems lights are on, fans are spinning, and SC is responsive or you are able to login to the SC or domain.
See Document 1010053.1: Troubleshooting Complete system Power Outages on Sun Fire [TM] Serengeti or LightWeight8 Systemsif the system has no power.

2. Verify that all Fan Trays are active and ok (not marked FAILED in showenvironment).

Confirm the status as shown in Document 1011930.1: Sun Fire[TM] (3800-6800) System Controller Application (ScApp) How To's.
If there is a failed Fan Tray then please follow the instructions detailed in Document 1008393.1: Troubleshooting Cooling Fan Failures on Sun Fire [TM] Serengeti or LightWeight8 Systems starting after Step 3 of that document.

3. Verify that a single System Board, I/O Board, Repeater, or System Controller's temperature is high as shown in showenvironment output.

Confirm the status as shown in Document 1011930.1: Sun Fire[TM] (3800-6800) System Controller Application (ScApp) How To's.

4. Verify the errors persist if the component is replaced.

Reference the appropriate System Service Manual for complete instructions on FRU replacement and procedures:

5. Confirm the errors persist on the same component when the other SC is main.

If the errors cease utilizing the new SC, then the former SC is suspect.
