Full-Duplex/Collision (Full-Duplex/Collision)
This indicator lights green when a corresponding port is in full duplex (FDX)
mode. Otherwise, it is blinking when collisions are occurring on the respective
port.
100M Link/Activity, 10M Link/Activity (100M LINK/ACT(green), 10LINK/
ACT(amber))
This indicator lights green when the port is connected to a 100Mbps Fast Ether-
net station and blinks green when transmitting or receiving data on the 100Mbps
network. This indicator lights amber when the port is connected to a 10Mbps
Ethernet station and blinks amber when transmitting or receiving data on the
10Mbps network.

DC Power Jack:
The supplied external 5VDC, 2.4A adapter provides power. As the HS-NH8100
does not have an On/Off power switch, plug the adapter into a 120VAC outlet to
power up.
MDI-X Jacks:
Use these jacks to connect networkable computers and peripherals. These are
MDI-X (Medium-Dependent Interface, Cross-wired) jacks, which means that
you can use ordinary straight-through CAT5 UTP cables. If you need to connect
another device with an MDI-X jack, such as a hub or Ethernet switch, you should
use a CAT5 crossover cable, or make the connection using the MDI-II jack
(described below).
Uplink Jack (MDI-II):
Use this jack to connect additional hubs/switches or network connections. This
jack is an MDI-II (Medium-dependent Interface, straight-wired), allowing you to
connect the HS-NH8100 to another device with a MDI-X port using an ordinary
straight-through cable, making a crossover cable unnecessary.
