LED Indicators
The VersaMux-4000 provides five front panel LED indicators. The LEDs are
controlled by the software so you can enable or disable them (see
). When disabled the LED indicators do not illuminate.

LED Descriptions
The following provides a general description of each indicator. In addition,
Table 6-1, “Front Panel Indicator State Descriptions,” on page 6-5
provides
descriptions of the LED states (see
for the VersaMux-
4000 alarms, their descriptions, and the interfaces they apply to).
POWER Indicator
The POWER LED indicates the state of the power supply in the VersaMux-4000. The
LED is off when the unit is not powered or when disabled by the
. The indicator illuminates (green) when the unit is powered on, the
power supply is operational, and enabled by the
.
AGGR Indicator
The AGGR (aggregate) LED indicates the status of the aggregate module (when
enabled by the
). The LED illuminates green when the
aggregate module is in normal operation. It illuminates red for faults (including
LOF). It illuminates yellow when the aggregate module operates in loopback mode.
If more than one condition exists, the LED indicates the highest priority state. Fault
is the highest priority, followed by loopback. Normal is the lowest priority state
and the system only indicates normal if no faults are present and the aggregate is
not in loopback mode. If the system detects a fault during loopback mode, it
displays the fault indication (red).
CLK REF Indicator
The CLK REF (Clock Reference) LED indicates the status of the selected system
timing reference (when enabled by the
). If the system loses
synchronization with the timing reference the LED illuminates red. The LED
illuminates green when the system is synchronized to the timing reference.
