Front Panel - Honeywell LC13-510 Manual

2.4 FRONT PANEL

The module front panel has the necessary windows and switch openings to accommodate
two nodes in a single module. Figure 2-3 shows the front panel for the Dual Node
Module. For each of the two power supplies, there are openings for the POWER switch
and RESET switch and a window to view the light-emitting diode (LED) status indicators.
Each power supply has a MARGIN pin jumper option which is a test/diagnostic aid and
should be left in the center (N) position at all times. There is also a LED indicator at the
right-center of the panel which indicates a fan module failure. For each of the two nodes,
the front panel includes an access window to view the indicators that are mounted on the
individual circuit boards. These indicators serve to monitor node performance and provide
diagnostic information for fault isolation. The detailed functions and operation of the
switches and indicators are discussed elsewhere in this manual.
