Removing and Installing Switch Fabric Cards
Procedures for removing and installing a CSC and SFC are described in the following sections:
• Removing a Card from the Switch Fabric Card Cage, page 12
• Installing a Card into the Switch Fabric Card Cage, page 13
• Verifying the Installation, page 16
These procedures apply to all available switch fabric card sets (2.5-, 10-, and 40-Gbps). When removing
and replacing cards, pay close attention to the ejector levers on the cards. Newer cards only pivot 70
degrees away from the card, while the ejector levers on some older cards pivot 90 degrees away from the
card.
Removing a Card from the Switch Fabric Card Cage
To remove a card from the switch fabric 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 connection
sockets on the front of the chassis or to a bare metal surface on the chassis (see Figure 3 on page 10).
Step 2 Open the air filter door on the front of the chassis, which shows the air filter door swung open (Figure 4).
Figure 4 Opening the Air Filter Door
a.
Loosen the two captive screws on each side of the air filter door.
b. Grasp the sides of the air filter door front cover and carefully swing the door out and down, away
from the switch fabric card cage.
The air filter door is attached to the chassis by a pair of spring-loaded arms on either side of the door.
When the door is fully extended away from the fabric card cage, it hangs down in front of the lower
card cage.
