CT Bus Cable Notes
Note: When the CT Bus cable is installed, it is important that the two end connectors must be
connected to boards. To achieve this consider the following:
• For single board systems, the CT Bus cable cannot be connected. For systems delivered as “single
board”, the cable is stowed in clips fastened to the underside of the Top Cover.
• If adding a second board to a system, the CT Bus cable should be taken from the clips and connected to
the two boards.
• For “two board” systems, the two end connectors of the CT Bus cable must be used, and only the center
connector may be left disconnected.
10.6 Replacing the Back-up Battery
A lithium battery on the Server Board provides power to maintain date and time settings in the absence of
main AC or DC power. When the battery starts to weaken, it loses voltage, and the date and time settings
may be wrong. The battery may be replaced by one labeled with Manufacturer and Part Number information
that is identical to that marked on the original battery, or contact your customer service representative for
advice on approved equivalent devices.
