
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 T1k 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, 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, the switch is not connected (or has lost connection) to a ShoreTel server.

When flashing fast, at least one port is handling an active call and at least one port is out of
service.
 Off: No ports are assigned.
Monitor and Telco LEDs
The Monitor and Telco LEDs indicate line coding, network framing, and loopback status. These LEDs
are color coded—green, yellow, and red. The Monitor and Telco LED descriptions follow.
Telco and Monitor LED alarms and errors are logged as switch events in ShoreTel Director’s event log.
 Line Coding: This LED indicates line coding status, as follows:

When green, the line coding signal is good.

When yellow, bipolar violations (BPV) are being received at one second intervals.

When red, a loss of signal (LOS) has occurred.

When flashing red, loopback is active (local or CO).

When off, the switch has no power.
