Appendix B.

Port Status Indicators

The port indicators on the AT-TS12T front panel provides visual

diagnostic and activity information for network analysis. The AT-TS12T

has a central bank of indicators, as shown in Figure 43.

Each 10BASE-T port supports the following indicator functions with one

dual-color front panel LED per port.

Note

The LEDs do not reflect real-time activity because a data packet is too fast

for the human eye to distinguish on the LED indicator; therefore, the hub

artificially stretches the LED ON time for easier observation.
