POWER LED Description
Off Both –48V fuses blown, power not supplied to
the shelf, or incorrect polarity on the voltage
supplied to the shelf.
Green Power supplied is the correct voltage and
polarity; backplane and hot insertion voltages
correct.
Red –48V input present; no backplane voltage and
no hot insertion voltage.
Amber –48V input and hot insertion voltage present;
no backplane voltage.

FUNCTIONALITY
The Total Access 4303 DC Power Supply furnishes the voltages
necessary for proper backplane operation. The DC Power Supply
also provides the voltages that enable hot insertion of the option
cards and SCUs. The D C P ower S upply does not, however, provide the voltages necessary to power individual option cards or the
SCUs as each card has its own DC-DC supply.
In addition, the DC Power Supply in slot PS-A provides alarm relay
output functional ity . If only one DC Power Supply is used, place
the DC Power Supply in PS-A to provide alarm relay facilities. The
DC Power Supply, as well as all Total Access 430 3 o ption modules and SCUs, has protection against the wrong voltage polarity
being applied to the shelf.
INSTALLATION INFORMATION
• Insert the module into either slot PS-A or PS-B (hot insertion
permissible).
• When power is supplied to the shelf, v erify that the Power LED is
green.
• If power is supplied to the shelf and the Power LED does not
illuminate, remove power and verify polarity.
• To v erify one or both -48V supply v oltages, use the SCU terminal
menus (see SCU Quick Start, 61200334L1-13A) and navigate
the following path:
