4. Remove the serial cable from the active CP blade and attach it to the standby CP blade.
5. Type
firmwareDownload -s -U v X.X.X (where X.X.X is the firmware version you are downloading) to download the firmware to
the standby CP blade.
The -s option also disables the autoreboot, so you must manually issue a reboot after the download finishes to initiate
firmwarecommit. Enter all requested information (use default values).
The -U option indicates that the download should come from the USB device. If you do not use this option, you are prompted
with Download from USB [No}: Type Y to download from the USB device.
6. When the download process finishes, type firmwareDownloadStatus to verify that the firmware has been updated.
7. Ensure that you are still logged in to the standby CP blade (the blade for which you just changed the firmware level) and type
reboot . The reboot of the standby CP will initiate a firmwarecommit to the secondary partition and log you out.
8. Log back in to the standby CP blade and type firmwareDownloadStatus on the standby CP blade to validate a successful
commit. This may take 10 minutes.
9. Log out of the standby CP blade and log in to the active CP blade.
10. Type
haEnable to re-enable HA on the active CP blade.
11. Type haShow and verify that the command output includes "HA enabled, Heartbeat Up, HA State synchronized". If not, re-enter
the command until you have verified that redundancy is achieved.
12. Type firmwareShow to verify that the firmware version has been updated and that the versions are the same on the two CP
blades.
13. Pack the faulty CP blade in the packaging provided with the new CP blade, and contact the switch supplier to determine the
return procedure.
14. Replace the chassis door ( Removal and replacement of the chassis door on page 83).
