Description
Allows you to connect up to four devices to the network.
A green LED indicates connection status when a device is using a
particular port.
Port 1 and port 2 are also power-forwarding ports; they can be used
with any standard networking device as well as to power any device
that requires IEEE 802.3af-compatible PoE.
An additional LED indicates when the port is forwarding power to a
device connected to that port.
The pass-through ports bypass the functionality of the switch and are
directly wired to the associated pass-through ports on the rear of the
unit. Pass-through ports allow connection to a separate network
segment or connection of an analog or digital PBX telephone.
Indicate whether the NJ1000 is being powered by a local power supply
(DC) or PoE.
Indicates network connection status for the uplink port on the rear of
the unit.
A green LED indicates a valid connection for the uplink port.
Can be used to power the NJ1000 with the optional local power
supply, 3CNJ1000PSL. NOTE: This power supply is required if the local
network does not supply Power over Ethernet.
Used to secure the NJ1000 to the wall-mount plate.
Press and release to restart the NJ1000.
