Removing a Core Routing Blade
Perform the following procedures to remove one core routing blade at a time with chassis power on. You must replace the
blade and ensure its operation before removing the other core routing blade. Removing both blades will power down the
chassis. To replace both blades at the same time, power down the chassis and perform the following steps.
1. Remove the chassis door.
2. Check the blade power and status LEDs and port status LEDs on the front of each blade to identify any possible
problems.
3. Before replacing a blade, establish a telnet or console connection to determine failure and verify operation after
replacement. Use the switchShow and slotShow commands to view the status of the blades.
4. Ensure that existing traffic through blade ICL ports will not be disrupted when the blade is removed by performing
steps under Preparing for Replacement .
5. Check for adequate cable slack. Ensure that there is plenty of cable slack to remove a blade without cable obstruction.
6. Ensure that the part number on the unit being replaced matches the replacement part number. The
chassisShow
command displays information about the blades, including part numbers (xx-xxxxxxx-xx), serial numbers, and
additional status.
7. Disconnect all cables and remove transceivers from the blade.
8. Label and then disconnect cables from the faulty core routing blade.
9. Loosen the captive screws for both ejector handles on the blade using a No. 1 Phillips screwdriver.
Loosening the screws initiates a hot-swap request and disconnects power from the blade. The spring-loaded captive
screws will pop out from the slot .63 cm (.25 in.) when fully disengaged. Do not eject the blade using blade handles
until screws disengage from the slot and the power LED is off.
10. Grasp both ejector handles and simultaneously pull them away from the center of the blade using equal pressure to
approximately 45 degrees (fully open).
As you move the handles, you will hear connectors disengaging from the backplane connector and possibly a slight
popping noise. This is normal and is due to the dense backplane. The blade will move out approximately 1.27 cm (.5
in.) from the slot when fully disengaged.
11. Pull the blade out from the slot slightly using the ejector handles until you can grasp the blade edges with your hands.
Make sure that the blade has cooled sufficiently to touch.
CAUTION
To avoid damaging blade and chassis, do not push the blade into a slot or pull the blade from a slot using the
ejector handles.
