ShoreGear 40 Voice Switch Chapter G: ShoreGear Switches
G.13.2.3 Network LEDs
The network LEDs (LAN1 and LAN2) indicate the speed at which the switch is
communicating with the network and whether there is network activity.
When both LAN connectors are connected into a redundant network configuration, one
network port is active while the other is in standby mode. If one LAN connection fails, the
switch activates the other port.
The network LED descriptions are as follows:
•Link/Activity: When lit, this LED indicates that the switch is connected to an
Ethernet network. This LED indicates network activity, as follows:
—When flashing, network activity is detected.
—When on (not flashing), heavy network activity is detected.
—When off, network activity is not detected.
This LED is not directly related to any switch’s individual network activity. For
example, if three switches are connected to the same hub and one switch’s Traffic
LED shows activity, the other switches will indicate the same activity.
—When green, the switch is connected to a 100BaseT network.
—When off, the switch is connected to a 10BaseT network.
