Front of the Hub

Hub status LEDs

The hub status LEDs indicate whether the hub is functioning properly. For

further details on error conditions indicated by the Status LEDs, see chapter

2, “Troubleshooting”.

LED State Meaning of LED

Power

(green)

On The hub is receiving power.

Off The hub is not receiving power.

Activity

(green)

Flickering ON while a packet is being transmitted. Normally, the LED

appears to flicker. In heavy traffic, it may appear on all the time.

Collision

(orange)

Flickering This LED is on while a collision is detected on any of the attached

cable segments. If collisions are infrequent (which is normal) the

light may be imperceptible. In a network with heavy traffic, the

LED will glow and flicker dimly, indicating collisions are

occurring. If it appears on continuously (with no flicker), it is a

possible indicator of a network fault. See chapter 2,

“Troubleshooting”.
