Tools and Supplies Needed

• Phillips (cross-head) screwdriver (#1 and #2 bit).

• Jumper removal tool or needle-nosed pliers.
• Antistatic wrist strap and conductive foam pad (recommended).
• Pen or pencil.
• Equipment log: as you integrate new parts into the system, add information about them to
your equipment log (page 197). Record the model and serial number of the system, all
installed options, and any other pertinent information specific to the system. You will need
this information when running the SSU.

Safety: Before You Remove Server Covers

Before removing covers at any time to work inside the system, observe these safety guidelines.
1. Turn off all peripheral devices connected to the system.
2. Turn off the system by using the push-button on/off power switch on the front of the system.
3. Unplug the AC power cords from the system or wall outlet.
4. Label and disconnect all peripheral cables and all telecommunication lines connected to
I/O connectors or ports on the back of the system.
5. Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap
attached to chassis ground of the system—any unpainted metal surface—when handling
components.
