Network LEDs
The ShoreTel 220T1A 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), the switch is connected to an Ethernet network.

When off, the switch cannot detect an Ethernet network.
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.
 100M

When green, the switch is connected to a 100BaseT network.

When off, the switch is connected to a 10BaseT network.
Status LED
The ShoreTel 220T1A has one status LED to provide general information about the ports. The color
and blink pattern of the LED indicate the port function:
 Status LED (Green)

When on steady, no ports are handling active calls.

When flashing fast (100 msec on/off), at least one port is handling an active call.
 Status LED (Yellow)

When on steady, no ports are handling active calls and at least one port is out of service.

When flashing slow (1 sec. on/off), the switch is not connected (or has lost connection) to
a ShoreTel server.

When flashing fast (100 msec on/off), at least one port is handling an active call and at
least one port is out of service.
 Off: No ports are assigned.
