Removing a control processor blade (CP8) The PowerConnect B-DCX continues to operate while a CP blade is being replaced if the redundant CP blade is active and a failover does not occur. You can prevent failover by entering the haDisable command. ATTENTION The instructions below refer to the top and bottom of each blade in the vertical orientation as used in the PowerConnect B-DCX.

FIGURE 2 Control processor blade (CP8) in a DCX-4S chassis Replacing a control processor blade (CP8) ATTENTION The instructions below refer to the top and bottom of each blade in the vertical orientation as used in the PowerConnect B-DCX. For the PowerConnect B-DCX-4S, because the blades are horizontally oriented, top should be read as left and bottom should be read as right. ATTENTION Follow ESD precautions (see “ESD Precautions” in your chassis’ hardware reference manual).

If the firmware version on the replacement blade does not match that on the active CP blade a warning message appears with the results of the firmwareshow command. You must bring the replacement blade to the same firmware level as the active blade using the firmwareDownload -s command to bring it up to the proper level.

7. Type firmwareDownloadStatus to verify that the firmware has been updated. 8. 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. 9. Log back in to standby CP blade and type firmwaredDownloadStatus on the standby CP blade to validate a successful commit. This may take 10 minutes. 10.
