Consistent with IEEE 802.3 specifications, Personal Hubs will detect
collisions, extend collision fragments, and automatically partition
and re-connect individual ports in order to keep problems on one
segment from causing downtime elsewhere on the network.
Personal Hubs include LINK and RX LEDs, located on top
of the unit above each RJ-45 port, and one LED for DC power
located at the rear near the external power supply connection. For
observing operational information from the LEDs, it is easy to
associate the status LEDs for each of the ports with the appropriate
port plug.

twisted pair.
Magnum H80Bs are also well suited for small- to-medium-
size office or lab environments (up to eight persons) that need an
independent Ethernet network. They operate as self-sufficient units
