LED Indicators

Collision LED

The yellow COL (collision) LED on the hub's front panel illuminates
when two or more stations on the network attempt to transmit pack-
ets simultaneously.

Note:
works. Excessive collisions may indicate that your net-
work is congested.
Refer to Appendix A, "Troubleshooting" for help with
determining problems on your network by monitoring
the Collision LED.

Link/Activity LEDs

The gr een Link/Activity LEDs, associated with each port, illuminate if
there is a device detected on the other end and if there is traffic on the
port.
The table below describes the possible status indications of the Link/
Activity LEDs.
On
Off
Blinking

Partition LEDs

The yellow Partition LEDs, associated with each port, illuminate if the
port has been partitioned. A port will automatically disconnect a seg-
ment if that segment causes too many collisions. The segment will be
reconnected when the collisions have subsided.
