Connecting the Devices

•The Data % LEDs light green on each hub, indicating the overall network utilization percentage of the Ethernet segment. Because a stack of hubs is a single segment, utilization is the same for each hub in the stack.

•If an optional uplink 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 LED lights green. When this LED is on, port 1 on the hub is disabled.

•If an NMM is installed in the expansion slot, the Enbl LEDs on each hub in the stack light green, indicating the hub is properly connected to the other hubs in the stack and is actively managed by an NMM.

•If an NMM is installed in the expansion slot, the Management LEDs light as follows:

–The Stat LED lights green, indicating the NMM passed the confidence test and is operating normally.

–The Mstr LED lights green, indicating the NMM is the master NMM in the stack.

•A Port Status LED for each port on the hub provides port status.
