PRELIMINARY
Reoving the I/O card
Remove I/O cards as follows:
1. Open the front door.
2. On the I/O cardcage door, turn the left and right knurled knobs ¼-turn
counterclockwise. Lower the door.
C Do not touch the electronic components or the connectors on the backplane
or on the circuit cards without being electrically grounded. Handle circuit
cards by their edges only. ESD can damage ICs, even if you cannot feel,
see, or hear it.
3. Grasp the ejector levers on the card to be removed (figure 6-16). Pivot the
ejector levers out and away from the center of the card to lever the circuit card
out of the backplane.
4. Slide the card out of the cardcage.
5. Place the removed card on an anti-static surface or in an anti-static container.
6. If a replacement card is not being installed immediately, raise the I/O
cardcage door to vertical and turn the left and right knurled knobs ¼-turn
clockwise.
7. If a replacement card is not being installed immediately, close the front door.
N If this circuit card removal is a permanent change to the size of the matrix, the
system must be be virtualized again to recognize the change. Virtualize the
system using the detailed instructions in chapter 3, “Virtualization/Control
Software”.
