Chapter 2 Installing the Cisco MDS 9200 Series
System Grounding
Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal
spot (unpainted surface) on the rack. Cisco recommends that you touch the clip to an unpainted rack rail
so that any built-up static charge is then safely dissipated to the entire rack.
Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows (See Figure 2-16.):
a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws
open, position the spring clip to one side of the system ground lug screw head, and slide the spring
clip over the lug screw head so that the spring clip jaws close behind the lug screw head.
Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or
the lug barrel.
b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip
directly over the head of the system ground lug screw or to the system ground lug barrel.
