How to Inspect for
Damage

Before installing any equipment, inspect it for damage as described in
Table 3-3. Report any damage found to the appropriate supervisory
personnel.

– Static sensitive equipment requires the use of ESD

protective gear such as a wriststrap to be used during
the installation and repair.

– A wriststrap is supplied with the installation hardware

and the ESD jack is located in the C–CCP Shelf in
the RF Cabinet (Figure 1-6).

WARNING
