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 itís own DC-DCsupply.

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 inPS-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.

INSTALLATION

Insert the module into either the slot labeled PS-A orPS-B.

When power is supplied to the shelf, verify 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 verify one or both -48Vsupply voltages, use the SCU terminal menus (see SCU Job Aid,61200334L1-22)and navigate the following path:
