Understanding 140T Hubs
Port LEDs
On the 140T, the port LEDs are located on a common panel with the hub
LEDs. These LEDs indicate port status, individual port speed, and port
activity.

Port Activity
Solid green
Device linked.
Blinking green
Receiving activity on that port.
Blinking orange
Port auto-disabled (partitioned). See below.
Off
No link detected.
Port Speed
Solid green
Device connected at 100Mbps
Off
Device connected at 10Mbps.
Partitioned ports
A port is automatically disabled (partitioned) by the hub when an invalid
condition occurs, such as too many consecutive collisions.
condition occurs, such as too many consecutive collisions.
Once the hub is able to transmit data to the port collision free, the hub
automatically re-enables (unpartitions) the port. Clients are usually not
affected by a partitioned port because the port is often unpartitioned very
quickly.

Usually, a partitioned port indicates an overloaded network or a
malfunctioning device (like an adapter card) on the network. To alleviate an
overloaded network, divide the network into smaller segments so that fewer
devices share the same fixed amount of bandwidth.
