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”.
