Chapter 1 Initial Inspection of the Server 3
System Inspection
Controls that have been improperly set and cables that are loose or improperly
connected are common causes of problems with hardware components.
Troubleshooting Power Problems
■ If the server will power on, skip this section and go to “Externally Inspecting the
Server” on page 3.
■ If the server will not power on, check the following:
1. Check that AC power cords are attached firmly to the server’s power supplies
and to the AC sources.
2. Check that the main cover is firmly in place.
There is an intrusion switch on the motherboard that automatically shuts down
the server power to standby mode when the cover is removed.
Externally Inspecting the Server
To perform a visual inspection of the external system:
1. Inspect the external status indicator LEDs, which can indicate component
malfunction.
For the LED locations and descriptions of their behavior, see “External Status
Indicator LEDs” on page 37.
2. Verify that nothing in the server environment is blocking air flow or making a
contact that could short out power.
3. If the problem is not evident, continue with the next section, “Internally
Inspecting the Server” on page 4.
