DESCRIPTION

The Total Access® 4303Plus DC Power Supply is a removable assembly that provides the voltages necessary for proper system operation. The unit features LEDs for overtemperature and DC output, an input fuse, and the ability to behot-swappedwhen used with another DC supply in the same chassis. The supply interfaces to the Total Access backplane through a48-pinconnector. The unit accepts one or two–48VDC inputs from the backplane and supplies–48VDC fused output for use with external input logic, +5 VDC as hot insertion bias voltage for modules, and +2.1 VDC for backplane termination. In addition, the Total Access 4303Plus DC Supply provides alarm relay ouputs when installed in slotPS-A.

The following features are supported on the Total Access 4303 Plus DC Power Supply:

Thermal limit indicator with open collector output

DC status indicator on the 2.1 and 5 volt outputs with open collector output

Short circuit protection

Compatible with existing Total Access DC Power Supplies (P/N 1200335L1)

TURNUP STEPS

To install the Total Access 4303 Plus DC Power Supply, perform the following steps:

1

After unpacking the Total Access 4303 Plus DC Power Supply, inspect it for damage. If damage is

2

found, file a claim with the carrier and then contact ADTRAN® Customer Service.

Pull the ejector tab on the bottom of the Total Access 4303 Plus DC Power Supply into the down

 

position.

3

Hold the Total Access 4303 Plus DC Power Supply by the front panel while supporting the bottom

 

edge of the module and align the module edge with the guide groove for slot PS-A orPS-B in the

 

chassis. If using only one Total Access Plus DC Power Supply module, insert the module in slot

 

PS-A in order to use the alarm relay outputs.

4

Gently but firmly push the module into the selected slot. Simultaneous thumb pressure at the top

 

(above the POWER LED) and at the bottom (below the electrostatic caution symbol) of the module

 

will ensure a good seat of the module pins into the backplane connector.

5

Apply power to the shelf and verify that the POWER LED is green. If thePOWER LED does not

 

illuminate, disconnect power, and verify polarity.

6 Push the ejector tab up and closed against the module front panel.

To verify one or both –48VDC supply voltages, use the SCU terminal and navigate to the following path:

COMPLIANCE

This product is NRTL listed to the applicable UL standards. The Total Access 4303 Plus DC Power

Supply is intended for installation in a type “B” or “E” enclosure in a Restricted Access Only area. The

Total Access 4303 shelf Frame Ground terminal must be connected to an earth ground to ensure that the front panel of the Total Access 4303 Plus DC Power Supply is properly grounded via the backplane connector.
