Electronic Control Module Power Supplies

The electronics control module (ECM) uses 200 W cPCI power supplies. These power
supplies are located below the HBT card in the Base module (there are no ECM power
supplies in the DEM) — see
module is different from the power supplies used for the robotics unit and the tape
drives.
Each Base module ships standard with two ECM power supplies used for N+1 and 2N
configurations. Order two additional ECM supplies for the 2N+1 configuration (see
"DC Power Supplies"

Robotics Unit Power Supplies

The robotics unit uses load sharing 1200 W DC power supplies located at the top of the
Base module (the DEM does not contain robotics DC supplies) — see
1200 W DC power supply used for the robotics unit is the same power supply used for
the tape drives.
Each Base module ships standard with two robotics DC power supplies used for N+1
and 2N configurations. Order a third DC power supply for the 2N+1 configuration
(see "DC Power Supplies"
