Updating the enclosure manager firmware
This section explains how to update the firmware of an EM card (enclosure manager firmware).
The EM firmware can be updated on the CLI of the EM serial console or EM console.
Important
● Do not shut down the power, such as AC power or uninterruptible power supply system
(UPS,) of the blade enclosure while you are updating the EM firmware. If the power is shut
down during the update, it will not only result in failure to complete the update but also
malfunction.
● Do not install/remove a module or power on/off a module while restarting an EM card.
Doing so not only results in failure to complete the update but also malfunction. Do not
switch on/off the ID LED of an installed module. The ID lamp may not be appropriately
turned on/off.
● When updating the EM firmware, back up or restore configuration data as necessary. If
two EM cards are not installed, the settings of the blade enclosure are erased unless you
back up or restore the configuration data. Passwords of users are not backed up. After
restoring the configuration data, reconfigure the passwords of the users. The time zone is
also not backed up. After the configuration data is restored, reconfigure it as necessary. For
information on how to configure the settings, refer to "Initial settings."
● When you restore configuration data, all the CPU blades installed on the blade enclosure
must be powered off. Otherwise, configuration data is not properly configured.
For information on how to update the EM firmware, refer to this document. See also the confirmation message
that is displayed before downloading or document files if they are attached with downloaded files.
