How to Install or Remove an MSC, FP, or LSP
Step 10
Carefully slide the line card into the slot until the ejector levers meet the edges of the card cage, then
stop
when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting the
card until the ejector lever hooks are fully latched.
Note
Line cards have guide pins that make initial contact with the midplane connector as you slide a
card into its slot.
Step 11
To fully seat the card in the midplane connector, grasp both card ejector levers simultaneously, then push
them both inward until they are flush against the front edge of the card carrier. After the guide pins make
contact, continue pushing the card carrier until the card ejector levers begin pivoting forward.
Caution
Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both
ejector levers may bind when you attempt to close the levers, thereby damaging or breaking
one or both of them.
Step 12
To ensure proper EMI shielding and prevent the line card from becoming partially dislodged from the
midplane, use a screwdriver to fully tighten the captive screws next to each line card ejector lever.
Caution
To ensure adequate space for additional line cards, always tighten the captive installation
screws on each newly installed line card
before
you insert another line card. These captive
screws also prevent accidental removal and provide proper grounding and EMI shielding for
the system.
What to Do Next
After performing this task:
•
Place the impedance carrier in an antistatic bag for storage and future use.
•
Verify that the card has been installed properly (see the
“Verifying the Installation of an MSC, FP,
or LSP” section on page 4-40
).
•
If you are performing the initial installation of the system, install the PLIMs (see the
“How to Install
or Remove a Physical Layer Interface Module” section on page 4-42
).
Removing an MSC, FP, or LSP
This section describes how to remove an MSC, FP, or LSP line card from the Cisco CRS 4-slot line card
chassis. For more detailed information on the MSC and FP, see
Cisco CRS Carrier Routing System 4-Slot
Line Card Chassis System Description.
A line card fits into any available line card slot and connects directly to the midplane.
