IDP & DC Distribution Panel
4.1.
INTRODUCTION
The C-DOT DSS MAX-XL utilizes a single supply potential of -48V DC as input for
all its power requirements. All AC and DC potential required for the operation of
the various cards in a frame of any cabinet and operation of VDU and Printers are
derived from this -48V DC source. In order to ensure a reliable and continuous
operation of MAX-XL, DC power distribution is carried out through two distribution
panels - Intermediate Distribution Panel (IDP) located in power room and DC
Distribution Panel (DCDP) in switch room.
