General Status LEDs
The following general rules apply to the BANDIT products’ LEDs:
• A lit green Power LED indicates that the unit is being supplied with power.
• A lit red Alarm LED indicates that the BANDIT has detected an alarm.
• A lit green Link LED indicates that there is a connection to another device.
• A flashing green Activity LED on an Ethernet WAN, LAN, or DMZ port indicates that
data is being received.
• A flashing green Activity LED on a serial port, modem port, 56/64 kbps CSU/DSU port,
or T1/E1 CSU/DSU port indicates that data is being exchanged.
On the expanded version of the BANDIT III, the Module Link LED indicates that the
BANDIT III’s four additional serial ports (sometimes called the BANDIT III’s RDU ports) are
up. The Module Activity LED indicates that there is communication between the BANDIT
III’s motherboard and its RDU ports. Each RDU Link LED (1, 2, 3, and 4) indicates that the
connection is up between that serial port and its connected device.
