Removing a core routing blade
About this task
Complete the following steps to remove the core routing blade.
Note: The device continues to operate while a core routing blade is being replaced.
Procedure
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 a failure and verify
operation after replacement. Use the switchShow and slotShow commands to view the status of the
blades.
4. Check for adequate cable slack. Ensure there is plenty of cable slack to remove a blade without cable
obstruction.
5. 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.
6. Ensure that traffic is not flowing through the blade (port status LED should be off) prior to
disconnecting cables.
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 #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 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.
12. Continue pulling the blade from the slot by the blade edges. As you slide out the blade, place one
hand under it for support. Do not support the blade by the injector handles after removal.
