Hub Operation

Front of the Hub

Hub Status and Port LEDs    

The hub status and LAN port LEDs indicate whether or not the hub is
functioning properly. 

LED

State

Meaning

Power (green) 

On

The hub is receiving power.

Off

The hub is not receiving power.

Fault  (orange) 

Off

Self tests have not detected any faults on the hub.

On

The hub or Expansion Slot module has failed its self-test after the hub has been
powered on or reset.  

Flashing

Slowly*

If the bridge module is installed, this LED indicates a problem with the 10Base-T
connection or part of the module itself.  Otherwise, this LED should only occur in
tandem with the RPS LED indicating an RPS failure.

Console  (green) 

Off

The hub is not being accessed by HP Stack Manager or if an SNMP module is
installed, the ASCII console.

On

This hub is currently being accessed by HP Stack Manager or the ASCII console.

Exp Slot (green)  

On

An optional module is properly installed in the hub’s back panel slot.

Off

An optional module is not installed.

Flashing

Slowly*

The module is performing its self-test (after hub power on or a reset). If the rate
of flashing increases and the flashing continues for more than approximately 30
seconds, refer to chapter 3, “Troubleshooting”. 

Uplink A, 
Uplink B (green)

Off

The Uplink port is disabled.

On

The Uplink port is connected and has successfully trained with an upper-level
hub.

Flashing

Slowly*

There is a problem with the cable or the permissions on the upper-level hub.

Flashing
Every 10

seconds*

The backup link of the primary link will flash every 10 seconds to indicate an end
node is detected on the other end and that the cable is working.
