Installation Guide for the Model EN516 Ethernet Hub
RJ-45 Ports
The front panel of the Model EN516 hub provides 16 RJ-45 10BASE-T ports. Two LEDs, the
Link/Rx LED and the Partition LED, are positioned at the top corners of each RJ-45 connector.
Both LEDs are described in Table 2-1.
Normal/Uplink Push Button
The Normal/Uplink push button on the Model EN516 hub allows you to select Normal (MDI-X)
or Uplink (MDI) wiring for port 16, eliminating the need to use a crossover cable to connect
similarly wired devices. Port 16 is configured for Normal wiring when the push button is in the out
position. When the push button is pressed in, Port 16 is configured for Uplink wiring.
Ports 1 to 15 on the hub cannot be configured for Uplink wiring. If you are using one of these ports
to connect to a Normal port in another hub, you must use an RJ-45 crossover cable to connect the
two ports. See Figure B-2 for crossover cable information.
