7.2 Determining a Faulty Component
To determine and isolate a faulty component, refer to “Troubleshooting the Server
Using Built-In Tools” on page 2-10.” This section can help you isolate a faulty
component using the following methods:
■ Fault and Status LEDs (see “Front Panel LEDs” on page 2-13)
■ POST LEDs, beep codes, and displayed error messages (see “Diagnosing System
Errors” on page 2-10)
7.3 Safety: Before You Remove the Cover
Before removing the system cover to work inside the server, observe these safety
guidelines:
1. Turn off all peripheral devices connected to the system.
2. Turn off the system by pressing the power button on the front of the system. Then
unplug the AC power cord from the system or wall outlet.
3. Label and disconnect all peripheral cables and all telecommunication lines
connected to I/O connectors or ports on the back of the system.
4. Before handling components, attach a wrist strap to a chassis ground of the system
(any unpainted metal surface).
7.4 Removing and Replacing the Cover
Many of the equipment replacement procedures require that you remove the chassis
cover. Before you remove the cover, observe the safety instructions in the section
titled “Safety: Before You Remove the Cover” on page 7-2
To remove the cover, follow these steps:
1. While pressing the blue latch button (A) with your left thumb, push down on the
top cover and slide it back using the heel of your right hand on the blue pad (see
Figure 7-1).
