Step 8 Disconnect any cables connected to the external alarm port on the alarm display.
Label each of the alarm display cables before you disconnect the cables.
Step 9 Disconnect the line card interface cables:
a. Identify the type of line card and its slot number. Write this information on a
piece of paper before you disconnect the cables. You’ll need this information
when you reinstall the line cards.
b. Identify the line card cable and its port connection. Label the cable with this
information.
c. Starting with the bottom port of the line card (on line cards with multiple
ports), disconnect the interface cable connectors from each of the line card
ports.
d. Loosen the captive screw at each end of the line card cable-management
bracket and pull the cable-management bracket away from the line card.
e. Carefully remove the cables from the horizontal cable tray and carefully place
the cable bundle out of the way.
f. Repeat steps a through e for each line card.
Step 10 Remove cards from the line card and RP card cage (see Removing and Replacing
Cards from the Line Card and RP Card Cage, page 5-38).
Step 11 Remove cards from the switch fabric and alarm card cage (see Removing and
Replacing Cards from the Switch Fabric and Alarm Card Cage, page 5-40).
Step 12 Remove the chassis air filter (see Cleaning or Replacing the Chassis Air Filter,
page 5-5).
