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.

Top rows: Port Activity

Bottom rows: Port Speed

Port Activity

Port Speed

1	2	3	4	5	6	7	8
9	10	11	12	13	14	15	16
1	2	3	4	5	6	7	8
9	10	11	12	13	14	15	16

Solid green = Link Blinking green = Activity Orange = Autodisabled

Solid Green = 100Mbps Off = 10Mbps

LED	Status	Meaning
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.

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.
