Note: You do not need to attach a supplemental system ground wire to the system
ground lug; the lug provides a direct path to the bare metal of the chassis.
After you install the system ground lug, follow these steps to correctly attach the
ESD wrist strap.
1. Attach the ESD wrist strap to bare skin as follows:
a. If you are using the ESD wrist strap supplied with the FRUs, open the
wrist strap package and unwrap the ESD wrist strap. Place the black
conductive loop over your wrist and tighten the strap so that it makes good
contact with your bare skin.
b. If you are using an ESD wrist strap equipped with an alligator clip, open
the package and remove the ESD wrist strap. Locate the end of the wrist
strap that attaches to your body and secure it to your bare skin.
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. We
recommend 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.
3. Plug the strap into the port (and alternatively clip an alligator clip onto the
grounding lug screws) by attaching either the spring clip or the alligator clip to
the ground lug screw as shown in Figure 1-6.
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.
c. Follow these additional guidelines when handling modules:
Handle carriers by available handles or edges only; avoid touching the
printed circuit boards or connectors.
