3. Establish a Telnet or console session.
Before installing a blade, establish a Telnet or console connection to determine
a failure and verify operation after installation. Use the
switchShow command
to view the status of 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 installed matches the
replacement part number (unless you are performing an upgrade). The
chassisShow command displays information about the blades, including part
numbers, 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 transceivers from the blade. For mSFP transceivers
(FC8-64 only), it is recommended that you use the pull tab to remove the
transceiver from the blade before removing the cable from the transceiver.
8. Unscrew the two thumbscrews from the top and bottom ejectors on the blade
(see Figure 31 on page 86) using the Phillips screwdriver. Unscrew the top
thumbscrew until it pops out. This initiates a hot-swap request.
9. Wait for the power LED to turn off in response to the hot-swap request before
removing the blade.
10. Open the ejectors by rotating them toward the center of the blade face. Pull
the blade out of the chassis using the ejectors (Figure 31 on page 86).
11.
If the blade is not being replaced by another blade, install a filler panel. See
“Removing and installing blade filler panels” on page 87.
