LAN LED Operation
The LAN LED indicates access to the Ethernet network. During normal operation, and while waiting for
an IP address, the LAN LED blinks to indicate network activity. This LED remains on when the Ethernet
interface is not actively accessing the network but the network is available, and it is off if network access
is not available. The definition of the network being available as indicated by this LED is that the Ethernet
physical interface is available and one or both of the Ethernet ports is connected to an active network.
STAT LED Operation
The STAT LED indicates the condition of the Ethernet interface in normal operational mode. If the STAT
LED is off, an event has been entered into the exception log and is available for viewing via the Station
Manager interface. The STAT LED is on during normal operation when no events are logged.
In the other states, the STAT LED is either off or blinking and helps define the operational state of the
module.
Ethernet Port LEDs (100 Mb/Speed and LINK/Activity) Operation
Each of the two Ethernet ports has two green LED indicators, 100 and LINK.
The 100 LED indicates the network data speed (10 Mbps or 100 Mbps. This LED is illuminated if the
network connection is 100 Mbps.
The LINK LED indicates the network link status and activity. This LED is illuminated when the link is
physically connected and blinks when traffic is detected at the port. Note that traffic at the port does not
necessarily mean that traffic is present at the Ethernet interface, since the traffic may be going between
ports of the switch.
