CAUTIONS
ESD can damage disk drives, boards, and other parts. Perform all procedures in this chapter only at an ESD workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis groundany unpainted metal surfaceon your system when handling parts.
Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. Do not touch the connector contacts. After removing a board from its protective wrapper or from the system, place the board component side up on a grounded, static free surface. If you place the server board on a conductive surface, the battery leads may short out. If they do, this will result in a loss of CMOS data and will drain the battery. Use a conductive foam pad if available but not the board wrapper. Do not slide board over any surface.
For proper cooling and airflow, always install the chassis side cover before turning on the system. Operating it without the cover in place can damage system parts.
Removing the Side Cover
You need to remove the chassis side cover, and in some cases the front cover, to gain access to components inside the system.
1.Observe the safety and ESD precautions at the beginning of this chapter.
2.Turn off all peripheral devices connected to the system.
3.Turn off the system by pressing the power button on the front panel, AND unplugging the AC power cord.
4.Label and disconnect all peripheral cables attached to the I/O panel on the back of the system.
5.Remove and save the three screws from the side cover; you will need them later to reattach the cover.
6.Place the fingertips of your left hand under the built in handle on the back of the cover.
7.Using an even pull, slide the cover backward, about an inch, until it stops.
8.Using your left hand, pull the back end of the cover toward you to disengage its bottom row of tabs from the notches in the chassis.
9.Using both hands, lift the cover upward to disengage the top row of tabs from the notches in the top edge of the chassis. Set the cover aside.
