Step 4 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface. Caution To prevent ESD damage, handle cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device. Step 5 Disconnect all cables and secure them out of the way, using cable ties, if necessary. Step 6 Using a No. 2 Phillips screwdriver, loosen the panel fasteners at the top and bottom of the card front panel. Using the Ejector Lever Step 7 Pull either the top or bottom ejector lever away from the card's front panel to disengage the trunk card from the backplane connector.
Caution Always use the ejector levers to disengage or seat dial shelf cards in the backplane.
Failure to do so can cause erroneous system error messages indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards. Step 8 Grasp the ejector levers and pull the card partially out of the dial shelf slot until you can grasp the card front panel with one hand. Place your other hand under the card to balance the weight of the card as you pull it out of the slot. Step 9 For all cards, read the following warning, then proceed to Step 10.
