Chapter 1 Migrating to a Cisco CRS-3 Carrier Routing System
How to Migrate to a Cisco CRS-3 Carrier Routing System (8-Slot)
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket
on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Choose an available CRS-3 fabric card slot for the CRS-3 fabric card.
Caution To prevent ESD damage, handle a CRS-3 fabric card by its ejector levers, the CRS-3 fabric
card carrier edges, or the slide-assistance arm only. Do not touch any of the electrical
components, pins, and circuitry.
Step 3 Remove the SFC impedance carrier or CRS-1 fabric card you are replacing from the designated slot, and
set it carefully aside. (See the “Removing an Impedance Carrier” section in the Cisco CRS Carrier
Routing System 8-Slot Line Card Chassis Installation Guide or the “Removing an SFC” section in the
Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Installation Guide.)
Note Remove only one impedance carrier or CRS-1 fabric card and install one CRS-3 fabric card at a
time. Be sure to verify that each CRS-3 fabric card is fully installed and secured before installing
another card.
Step 4 Remove the CRS-3 fabric card you are installing from its antistatic packaging.
Step 5 Use the screwdriver to unscrew and remove the sheetmetal cover over the HBMT connectors on the rear
of the CRS-3 fabric card, and set it aside.
Step 6 Remove the caps from the HBMT connectors on the back of the card, and set them carefully aside.
Step 7 Visually inspect the connector on the card before you insert it into the chassis. Do not attempt to install
a card with a damaged or dirty connector, as this action may damage the backplane connector or OIM.
Note Rails exist on the upper and lower left edges of the card that align with the slots in the card cage.
When you install a card in the card cage, make sure that you orient the card correctly and align
these rails when sliding the card into the chassis.
Step 8 Grasp the slide assistance arm with one hand and place your other hand under the carrier to support and
guide it into the correct slot. DO NOT LIFT CARDS BY THE SLIDE-ASSISTANCE ARM; lift them
from the bottom, using the slide-assistance arm only as an aid for balance.
Caution A CRS-3 fabric card weighs about 30 lb (14 kg). You should use two hands when handling the
CRS-3 fabric card.
Step 9 Slide the card halfway into the slot. Avoid touching the card circuitry and any connectors.
Step 10 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.
