SAN512B-6 Installation, Service, and User Guide
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.
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.
