4.1 Front Panel Indicators and Controls
4.1.1 Tx & Rx Indicators
Flashing amber LEDs indicate active transmit and receive communications on the Expander Bus.
4.1.2 Health Indicator
A steady green LED indicates a fault-free Bridge module; an extinguished LED indicates a fault.
4.1.3 On-Line Indicator and Switch
Raising and releasing the on/off-line switch momentarily takes the module off-line, which is mirrored by
the steady On/Off state of the amber On-Line LED. Repeating the action brings the module back on-
line.
Prior to hot-swapping the module for repair, it should be taken off-line using this feature to ensure a
clean exit from the system. The replacement module is then placed on-line using the switch.
