Removing and Replacing a Card in the Lower Card Cage
Step 5 On the card you intend to remove, grasp the card ejector levers and simultaneously pivot
both ejector levers ninety degrees inward (away from the sides of the card cage) to unseat
the card from the backplane connector. (Refer to Figure 5.)

Step 6 Touching only the metal card carrier, slide the card out of the lower card cage slot and
place it immediately on an antistatic mat.
If you plan to return the old clock and scheduler card or switch fabric card to the factory, repackage
it in the shipping container you received with the replacement card.
Installing a Card in the Lower Card Cage
Perform the following steps to install a new or replacement card in the lower card cage:
Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets
located on the front edges of the upper card cage or to bare metal on the frame.
Step 2 Select the proper slot in the lower card cage to install the card. Cards installed in the lower
card cage are color-coded and keyed. Clock and scheduler cards are color-coded light
blue and are keyed to install only in the upper two slots. Switch fabric cards are
color-coded magenta and are keyed to install only in the bottom three slots.
Step 3 Grasp the card carrier edge with one hand and place your other hand under the carrier to
support and guide it into a matching color-coded slot. Slide the card halfway into the
lower card cage slot. Avoid touching the card circuitry or any connectors.
