Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System
How to Migrate to a Cisco CRS-3 Carrier Routing System (8-Slot)
Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both
ejector levers might bind when you attempt to close the ejector levers, thereby damaging or
breaking one or both ejector levers.
Step 11 Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the
tabs on each side of the card cage slot.
Note A CRS-3 fabric card has guide pins that make initial contact with the backplane connector as
you slide the card into its slot. After the guide pins make contact, continue pushing on the card
carrier until the card ejector levers begin pivoting forward, toward the handle in the card carrier.
Step 12 To seat the card in the backplane connector, grasp both card ejector levers and pivot them inward toward
the handle in the card carrier until they are flush against the front edge of the card carrier.
Note You may hear a crunching noise when seating the card; this noise is normal.
Step 13 Use the screwdriver to turn the two captive screws on the front panel of the CRS-3 fabric card clockwise
to seat the card firmly in the slot.
What to Do Next
After performing this task, you may replace any front cosmetic cover plates (see the “Installing the Front
and Rear (SFC) Side Cosmetic Components” section in the Cisco CRS Carrier Routing System 8-Slot
Line Card Chassis Installation Guide).
For complete information on regulatory compliance and safety, see Regulatory Compliance and Safety
Information for the Cisco CRS Carrier Routing System. For information on removing the front cosmetic
cover plates, see the “Removing the Rear (OIM) Side Cosmetic Components” section in the Cisco CRS
Carrier Routing System 8-Slot Line Card Chassis Installation Guide. For information on how to power
down your chassis, see the “Powering an AC Power Shelf Energized Chassis Up and Down” section in
the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide or the “Powering a
DC Power Shelf Energized Chassis Up and Down” section in the Cisco CRS Carrier Routing System
8-Slot Line Card Chassis Installation Guide. For information on installing an OIM, see the “Installing
an OIM” section in the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide.
Verifying the Installation of the CRS-3 Fabric Card
This section describes how to verify that the CRS-3 fabric card has been properly installed. Figure 1-10
