For the SPT-N11U/SPT-N12U-220 configuration, the rightmost power socket is also for
the system (the system controller and fans); moving to the left, the next socket powers
module slots 1 - 4, then 5 - 8, etc., with the leftmost socket powering slots 9 - 12.
For either chassis configuration, if all the slots for a particular power socket are not in use,
the socket does not have to be powered. The status of the slot power is indicated by the
LEDs on the front panel above each slot. Please refer to the Spirent TestCenter Hardware
Reference for information about the LEDs. The system power socket must always be
powered to run any of the module slots.
Note: 2-slot cards require both occupied slots to be powered.
The power sockets are a C20 type, and your system ships with the appropriate number of
C19 power cables that fit into the C20 receptor for the configuration and region of
intended use. You must use these cables. Optionally, for connection to a PDU with the
appropriate number and sized circuits, ACC-2020A C20 to C19 power cords can be used.
