Figure8-4 Removing an interface module with ejector levers
Replacing an interface subcard
IMPORTANT:
•
If you are not to install a new interface subcard after removing the old one, install a filler panel in
the slot.
•
When installing a filler panel, orient it with the blade of the screwdriver image on it facing
upwards. First insert the filler panel right side into the slot, and then push the left side into the slot.
1. Remove the cables from the interface subcard.
2. Prepare an antistatic mat to place the removed interface subcard.
3. Wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably
grounded.
4. Use a Phillips screwdriver to loosen the captive screws on the interface subcard.
5. Open the ejector levers on the interface subcard and then pull the interface subcard part way
out of the slot.
6. Supporting the interface subcard bottom with the left hand, slowly pull the interface subcard out
of the slot along the guide rails with the right hand.
7. Place the removed interface subcard on the antistatic mat.
8. Install a new interface subcard. For the installation procedure, see "Installing interface
subcards."
