When the subslot is not in use, an EPA blank filler plate must fill the empty subslot to allow the router to
conform to EMI emission requirements and to allow proper airflow across the installed modules. If you plan
to install the EPA in the subslot that is not in use, you must first remove the EPA blank filler plate.
Figure 48: Handling an EPA
Although the metal carrier helps to protect the EPA from ESD, wear a preventive antistatic strap whenever
you handle the EPA. Ensure that the strap makes good skin contact and connect the strap
’
s clip to an unpainted
chassis surface to safely channel unwanted ESD voltages to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
The following are the guidelines for preventing ESD damage:
•
Always use an ESD wrist strap or ankle strap when installing or replacing an EPA. Ensure that the ESD
strap makes contact with your skin.
•
Handle the EPA by its metal carrier edges and handles; avoid touching the printed circuit board or any
connector pins.
•
When removing the EPA, place it on an antistatic surface with the printed circuit board components
facing upward, or in a static shielding bag.
Removing an EPA
Procedure
Step 1
Attach an ESD wrist strap between you and an unpainted chassis surface.
Step 2
Stop the EPA so that there is no traffic running through the EPA when it is removed.
Removing an EPA while traffic is flowing through the ports may cause system disruption.
