8-port Fast Ethernet 10/100M NWay Switch
DC Power Jack: Power is supplied through an
external AC power adapter. Check the technical
specification section for information about the AC
power input voltage.
Since the switch does not include a power switch,
plugging its power adapter into a power outlet will
immediately power it on.
MDI-X Jacks: Use these jacks to connect stations
to the hub. These are MDI-X (Medium-Dependent
Interface, Cross-wired) jacks, which mean, you can
use ordinary straight-through twisted-pair cables
to connect user machines and servers to the hub
through them. If you need to connect another
device with an MDI-X jack, such as another hub or
an Ethernet switch, you should use a crossover
cable, or make the connection using the MDI-X
jack (described below). For more information about
crossover connections.
