How to Install or Remove a Physical Layer Interface Module
Prerequisites
Before performing this task, remove any front (PLIM) side cover plates.
Required Tools and Equipment
You need the following tools to perform this task:
• ESD-preventive strap
• Medium Phillips screwdriver
Steps
To remove the PCMCIA card, follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket
on the front (PLIM) side or a bare metal surface on the chassis.
Step 2 Using the screwdriver, loosen the captive screw at the bottom of the PCMCIA slot door on the faceplate
of the card.
Step 3 While lifting the hinged PCMCIA slot door up, press the release button for the card slot to disengage the
card from the card.
Step 4 Carefully pull out the far-left removable PCMCIA flash card.
Step 5 Place the removed PCMCIA card on an antistatic mat, or place it in an antistatic bag if you plan to return
it to the factory.
Step 6 If the PCMCIA card slot is to remain empty, close the door to keep dust out, and tighten the captive screw
with the screwdriver. Otherwise, install the new PCMCIA card.
