Removing the cover
Use this information to remove the cover.
To remove the server cover, complete the following steps:
Step 1. Read the safety information that begins on “Safety” on page iii and “Installation guidelines” on page
41 .
Step 2. Turn off the server and peripheral devices and disconnect the power cords and all external cables,
if necessary.
Note:
When you disconnect the power source from the server, you lose the ability to view the
LEDs because the LEDs are not lit when the power source is removed. Before you disconnect the
power source, make a note of which LEDs are lit, including the LEDs that are lit on the operation
information panel, on the light path diagnostics panel, and LEDs inside the server on the system
board.
