Upgrading Circuit Cards

The Remote Maintenance Card

The Remote Maintenance (RMB) card is PC-AT based. It draws its power from
the PC host bus. An optional external AC power adapter is available that plugs
into the faceplate of the RMB card. This adapter provides power to operate the
RMB card in situations where the power supply in the system fails.
