port#16/24. You can either use Port#16/24 or the “Uplink”port.

The “Uplink”port is used for connecting another hub through

an ordinary straight-wired twisted-pair cable by running one end

of a straight cable to the “Uplink”port and the other end to

another hub’s standard 'station' port i.e 1-16 or 1-24

On the front panel, there are several LED indicators for

monitoring the device itself, and the network status. At a quick

glance of the front panel, the user will be able to tell if the

product is receiving power; if it is monitoring another hub or

concentrator; or if a problem exists on the network.
