4.1 Ensuring ESD Protection
Please read the warning bulletin below before performing hardware maintenance
procedures:
Electrical Component Sensitivity
Electronic components on printed circuit boards are extremely sensitive to
static electricity. Normal amounts of static electricity generated by clothing can
damage electronic equipment. To reduce the risk of damage due to
electrostatic discharge (ESD) when installing or servicing electronic equipment,
it is recommended that anti-static earthing straps and mats be used.
Note: Place all removed components in an anti-static bag.

Before removing or inserting components from the chassis:
1. Locate the two ESD connectors on the chassis - one is located on the right rack-
mounting flange; the other is located on the rear panel of the Fan Tray module.
2. Attach yourself to an ESD wrist strap and then connect the other end to one of the
ESD connectors (mentioned in Step 1), using a banana plug or an alligator clip.
