To protect yourself and the equipment, observe the following precautions
when working on or in the server.
Table 1-1 Safety Precautions
Precaution
Ensure the AC cord connects the server to a grounded electrical outlet. The
power cord provides a ground path for the unit to bleed off electrostatic voltage.
Wear a conductive wrist strap or foot strap when you handle printed circuit
boards. Proper use of a conductive strap reduces the risk of damage to the
boards by discharging static electricity to ground.
The mat provides ESD protection when used with a wrist strap or foot strap.
The mat also cushions the board to prevent breakage of any small parts that
contact the bench surface.
Handle the PC board by the edges only. Store the board in an antistatic bag.
Install all cover panels after performing any service work on the system. The
panels keep out foreign objects to prevent physical damage to internal parts and
guide airflow to prevent overheating.
Install airflow restrictor boards in all unused card cage slots. Unused, open slots
severely reduce the cooling capability of the system and can lead to equipment
damage from overheating.
