Indigo 1-DP power supply module
The Indigo 1-DP is fitted with a pair of removable slim-line 55-watt power modules.
These modules fit side by side in the place of the single PSU module in an adapted Indigo
1 frame.
Note:
The maximum power is limited to 55 Watts. Ensure this maximum is not exceeded by
the inappropriate selection of cards fitted into the frame.
Left/Right conversion
For a pair of PS-55i power supply modules to fit side-by-side in the 1U power supply bay
it is necessary for them to be handed i.e. a power supply module set for the right hand
position will not fit into the left-hand and visa versa. Reconfiguring a PS-55i to its
opposite handing requires the power supply module to be repositioned on its carrier-
board. The removal of two fixing screws will allow this repositioning of the module.

Dual power supplies mother-board.
The PS-55i power supply modules are mounted into the Indigo 1-DP frame by way of a
retained mother-board. This mother-board which remains in situ contains the CPU, alarm
relay and low voltage fusing for the frame bays. It is also the purpose of the mother board
to connect the two PS-55i power supplies to the frame and supply the mains input
connection. There are no user adjustments on this board so removal should not normally
be necessary.
