LED

Meaning

NETWORK LOAD

These ten GREEN LEDs approximate the percentage of the switch’s capacity that is in use. The percent-
age of usage increases as a gradient from left to right much like a dynamic bar chart.

10 BASE-T PORT ACTIVITY

LINK

RCV

COL

This steady Green LED indicates that the particular port has a valid link and 
is not partitioned.

This Flashing Green LED indicates that the port is receiving Ethernet pack-
ets.

This Flashing Amber LED will flicker to indicate SQE or collision. Occasional 
collisions are normal in Ethernet networks. Excessive collisions is an indica-
tion of possible segment problems. A constantly illuminated Collision LED 
may indicate that there is a port, cabling, or excessive traffic problem.

100BASE-TX

LINK

RCV

COL

This steady Green LED indicates that the particular port has a valid link and 
is not partitioned.

This Flashing Green LED indicates that the port is receiving Ethernet pack-
ets.

This Flashing Amber LED will flicker to indicate SQE or collision. Occasional 
collisions are normal in Ethernet networks. Excessive collisions is an indica-
tion of possible segment problems. A constantly illuminated Collision LED 
may indicate that there is a port, cabling, or excessive traffic problem.
If the port is configured for full duplex, this LED has no meaning.

STATUS

Fault

On – This RED LED will illuminate when the switch detects a general fault 
condition.

Pwr

On – Indicates the AT-TS90TR is receiving power and the voltage is within 
the acceptable range.
Off – Indicates the AT-TS90TR is not receiving power.

Button

Function

Reset

Restarts the system software.
