Connectors and LEDs on Board Fronts

This section describes the connectors and LEDs on the boards.

The indication of board status with dual color LED is:

Note:

DC/DC-, MGU-, TLU77- and ASU-boards deviate from above. See the figures below regarding how they differ.

ROF137 6303/R1A-R3A

The DC-converter is quipped with three LED diodes that have the following function and indications:

  • Yellow diode: -48 volt input voltage is supplied to the converter.

  • Green diode: +5 volt is present in the back plane.

  • Red flashing diode: Board is faulty. Investigate and replace the board if necessary.

No external alarm signal is provided in the front panel or in the back plane.

ROF137 6303/R5A and higher

The DC-converter is equipped with 2 LED diodes that have the following function and indications:

  • The upper green LED diode: -48 volt input voltage is supplied to the converter.

  • The low green diode: +5 volt is present in the back plane.

Note:

ELU26 and TLU79 has equal fronts, only different printing.

  • TLU83/4 board has different connectors than TLU83/1 board. It have RJ45 connectors and uses standard network cables.

  • ELU34/7 board has different connectors than ELU34/6 board. It have RJ45 connectors and uses standard network cables.

The following figure depicts the front connectors for TLU83/4 board.
