This document describes a problem that the Media Experience Engine 3500 (MXE 3500) might experience in
the bootup process with the Battery Backup Unit (BBU) of the MegaRAID controller.

The console displays this error message when there is a problem with the BBU:

The battery hardware is missing or malfunctioning, or the

 battery is unplugged, or the battery could be fully

 discharged.  If you continue to boot the system, the

 battery−backed cache will not function.  If battery is

 connected and has been allowed to charge for 30

 minutes and this message continues to appear, then

 contact technical support for assistance.  Press 'D'

 to disable this warning (if your controller does

 not have a battery).

...

Press any key to continue, or 'C' to load the

 configuration utility.

If you press any key the device boots up, but it is not clear if the battery is in a good state or not.

See Set up CIMC for UCS C−Series Server for information on how to configure the Cisco Integrated
Management Controller (CIMC).

Note: These steps require that the CIMC is configured and works correctly.

The first step is to check the MXE 3500 in order to see if it recognizes the BBU. Use a Secure Shell (SSH)
client to connect to the MXE 3500 with the CIMC management address. Enter the commands shown in bold
in this example:

MXE−3500−1# scope chassis

MXE−3500−1 /chassis # show detail
