Before performing any maintenance procedures, read the following warning bulletin:
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
when installing or servicing electronic equipment, it is recommended that anti-
static earthing straps and mats be used. For ESD protection procedure, see
Section
6.1 Ensuring ESD Protection before Maintenance
Procedures
The procedure below describes how to protect the device from electrostatic discharge
(ESD). This must be done before removing or installing chassis modules.
Note: Place all removed components in an anti-static bag.

To protect the device from ESD:
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.
