Verifying Installation
After you complete all port and power connections to the Express hub,
verify that the installation is successful by observing the LEDs on the
front panel of the hub.
This section provides information about the operating conditions of
the LEDs after power is first applied to a newly installed Express hub.

Checking the LEDs
When power is first applied to the Express hub, a confidence test is
performed. During the confidence test, the hub Stat LED lights amber
to indicate the confidence test is in progress.
When the confidence test is successfully completed, the LEDs on the
hub front panel should appear as follows:
•
The Pwr LED lights green to indicate the hub is receiving power
from the hub AC power supply.
•
The Stat LED lights green to indicate the hub has passed the
confidence test and is operating normally.
•
The Data % LEDs light green on each individual hub to indicate
the overall network utilization percentage of the Ethernet segment
for a standalone hub or a stack of hubs.
•
If an optional media adapter module is installed in the media
adapter slot, the appropriate cable is connected to the media
adapter port, and the link status is good, the Media Adapter 1 LED
lights green.
