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:
Step1 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.
Step2 Using the screwdriver, loosen the captive screw at the bottom of the PCMCIA slot door on the faceplate
of the card.
Step3 While lifting the hinged PCMCIA slot door up, press the release button for the card slot to disengage the
card from the card.
Step4 Carefully pull out the far-left removable PCMCIA flash card.
Step5 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.
Step6 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.
