INSTALLATION INFORMATION
• Insert the module into either slot PS-A or PS-B (hot insertion
permissible).
POWER LED
Description
Off
Both –48V fuses blown, power not supplied to
the shelf, or incorrect polarity on the voltage
supplied to the shelf.
• When power is supplied to the shelf, verify that the Power LED is
green.
Green
Power supplied is the correct voltage and
polarity; backplane and hot insertion voltages
correct.
• If power is supplied to the shelf and the Power LED does not
illuminate, remove power and verify polarity.
Red
–48V input present; no backplane voltage and
no hot insertion voltage.

• To verify one or both -48V supply voltages, use the SCU terminal
menus (see SCU Quick Start, 61200334L1-13A) and navigate
the following path:

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 DC Power Supply 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 functionality. 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 4303 option modules and SCUs, has protection against the wrong voltage polarity
being applied to the shelf.
