PLDS CARD

The PLDS card, reference HJ4206A, is fitted to a rear equipment slot, connector B.
One PLDS card is required for each LDS to be remotely powered.
The equipment slot depends on the slots and quantity of LDS cards in the back plane.
The PLDS card is used to connect the remote power supply portion of the LDS distribution
frame cable (octopus cable).
The card based remote power supply can either be 48 V or 40 V voltage fed back into the
card via the distribution frame cable (octopus cable ).
The fuses located on the PLDS card are used to select 40 V and 48 V voltage (basically
48 V except if a remotely powered S0 interface must be configured on the card).
If the card has a remote powered S0 ISDN interface, you must select 40 V.
Any other cards will be powered by 48 V.
The PLDS card is a plug-in type card, used to extract the ISDN 40 V or Subscriber 48 V
remote power supply voltages and the LDS card S0 interfaces.
Install PLDS card like an equipment card cable (LR, LAJ, LAB etc.) between the equipment
cable and the back panel connector of an equipment slot.
Before powering the LDS card, each voltage polarity is protected by 2 A fuses
Two spare fuses are provided on the PLDS card.
The 40 or 48 V voltage is selected using the fuses. Two fuse holders are provided for each
voltage. Fit the fuses to the corresponding positions to select the voltage.
The PLDS kit is supplied with locking tabs to be installed in place of the spacers of
connector B in the equipment slot. These tabs are used to secure the PLDS/cable
assembly in position.
