▼ Prevent ESD Damage

Many components housed within the chassis can be damaged by electrostatic
discharge. To protect these components from damage, perform the following steps
before opening the chassis for service.
1. Prepare an antistatic surface to set parts on during the removal, installation, or
replacement process.
Place ESD-sensitive components such as the printed circuit boards on an antistatic
mat. The following items can be used as an antistatic mat:

2. Attach an antistatic wrist strap.
When servicing or removing server components, attach an antistatic strap to your
wrist and then to a metal area on the chassis.

▼ Remove the Server Top Cover

Caution – Removing the top cover without properly powering down the server and
disconnecting the AC power cords from the power supplies will result in a chassis
intrusion switch failure. This failure causes the server to be immediately powered off.
Any changes you make to the memory riser or DIMM configurations will not be
properly reflected in the service processor's inventory until you replace the top cover.
1. Ensure that the AC power cords are disconnected from the server power
supplies.
