Verifying System Operation

Verify that all attached devices have a valid connection. The
hub monitors link status for each port. If any device is properly
connected to the hub and transmitting a link beat signal, the
Link indicator lights for the corresponding port. If the Link
indicator fails to light when you connect a device to the hub,
check the following items -
• Be sure the media cable is properly attached to the connected
device and the hub. Verify that the cable connector snaps
into place when attached.
• See if the media cable is functioning properly by using it for
another port and attached device that displays valid
indications when connected to the network.
