Removing and Installing the Alarm Card

Step 3 Grasp the sides of the air filter door front cover and carefully pivot the door down, away from the switch

fabric and alarm card cage (Figure 8).

The alarm cards are the two right-most cards in the switch fabric and alarm card cage. They are labeled

Alarm.

Step 4

Select the appropriate alarm cards in the switch fabric and alarm card cage. Grasp the two card ejector

levers and simultaneously pivot both ejector levers 70 degrees away from the front edge of the card

carrier to unseat the card from the backplane connector.

Step 5 Touching only the metal card carrier, slide the alarm card out of the slot and place it directly into an

antistatic sack or other ESD-preventive container.

Installing an Alarm Card

To replace an alarm card in the switch fabric and alarm card cage, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD sockets on

the front of the chassis or to a bare metal surface (see Figure 4 on page 9).

Step 2 Remove the replacement alarm card from its antistatic sack or ESD-preventive container.

Step 3 Determine the assigned card slot for the card by checking the label attached to the edge of the card carrier

(near the bottom ejector lever).

Note There are alignment grooves on each slot in the switch fabric and alarm card cage. When you

reinstall a card in the switch fabric and alarm card cage, make sure you align the top and bottom

edges of the card carrier in the slot grooves.

Step 4 Grasp the card carrier handle with one hand and place your other hand under the carrier to support and

guide it into the correct slot. Slide the card halfway into the slot. Avoid touching the card circuitry or

any connectors.

Step 5 Pivot both card ejector levers so the openings on the card ejector cams at the top and bottom of the card

pass over the tabs on each side of the card cage slot.
