Updating the EM firmware
This section explains how to update the firmware of an EM card (EM 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, which is supplied to EM cards 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, and power on/off a module while restarting an EM card.
An attempt to do 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
lit on/off.
For information on how to update the EM firmware, refer to this document. (See also the confirmation
message that is displayed before download or document files if they are attached with download files.)
