the system.

Touch the bare metal of the base unit or cabinet to discharge any accumulated static
charge.

Avoid servicing the system in areas known to have electrostatic problems such as on
rugs and carpets.

Handle all printed circuit boards as little as possible and by the edges only. Leave the
boards in their protective packaging until you install them.

Do not drop, jar, or bump the disk drives. Handle all disk drives by the edges and avoid
touching connector pins or printed circuit board components.

Always power off the system base unit before powering off the cabinet, and leave the
power cord connected to maintain ground.
Replacing RAID Controllers
NOTE To replace a RAID controller board in a rack-mount base unit, refer to the system’s hardware
documentation for the rack-mounted system. The system documentation specifies the slots
for the RAID controller.
