2-4.2 Wiring The Power Inputs
HUE-500SN & HUE-500SEN are powered up by an external power supply. On the top panel, a removable
2-pin terminal block (See Panel Layout – Top Panel) is provided for DC power connection. To connect to
the power supply, insert V+ and V- wire into power contacts. Then, tighten the wire-clamp screws to prevent
power wires from loosening. If the power supply is connected correctly, then the PWR LED on the front panel
will light in green.
Be sure to disconnect the power cord before installing and/or wiring your switch.
Be sure of the maximum possible current when wiring connections. If the current goes above
the maximum ratings, the wire could overheat and result in serious damage to your switch.
The acceptable wire range is 12 to 24 AWG.
2-4.3 Wiring the Earth Ground
An earth ground connector is provided on the top panel with an earth ground sign next to it. Grounding the
device can help to release leakage of electricity to the earth safely so as to reduce injuries from
electromagnetic interference (EMI).
Prior to connecting to the power, it is important to connect the ground wire to the earth. Follow steps below to
install ground wire:
1. Loosen or remove the grounding screw.
2. Attach the grounding screw to the ring-type or fork-type terminal of the grounding cable. Make sure that
the grounding cable is long enough to reach the earth.
3. Use a screwdriver to fasten the grounding screw.
2-4.4 Ethernet Cabling
For RJ-45 port connection, prepare twisted-paired, straight through Category 5/5e cables for Ethernet
connection. The linking distance between the switch and the network device must be less than 100 meters
(328 ft.).
For 10Mbps connections, use 100ΩCategory 3, 4 or 5 cables.
For 100Mbps connections, use 100ΩCategory 5/5e cables.
The UTP port (RJ-45) LED(s) on the switch will light up when the cable is connected with the network device.
Please refer to the LED Indicators section for more information.
