Step 3 Use the crimping tool to secure the grounding cable in the grounding lug.
Step 4 Remove the adhesive label from the grounding pad on the chassis.
Step 5 Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert
the two M4 screws with washers through the holes in the grounding lug and into the grounding pad (see
Callouts 2 and 3 in Figure 2-6).
Step 6 Ensure that the lug and cable do not interfere with other equipment.
Step 7 Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your
site to ensure adequate earth ground.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly
handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are
fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral
components of the carrier. Although the metal carrier helps to protect the board from ESD, always use
an ESD grounding strap when handling modules.
