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.
POE The Switch supports two power systems, 12VDC or powered from POE. Port
# 1 supports 802.3af in-line power. Either power system can be deployed to
the Switch at a time. And 12VDC will not active if POE port and POE power is
in use.
Numbered
MDI/MDI-X
Jacks:
Use these jacks to connect stations to the Switch. These are numbered
MDI/MDI-X jacks, which mean, you can use ordinary straight or crossover
twisted-pair cables to connect user machines and servers to the switch
through them.
Note:
1. The Switch is a power-required device, it means, the Switch will not work until it is powered.
If your networked PCs will need to transmit data all the time, please consider use an UPS
(Uninterrupted Power Supply) for your Switch either through POE port or DC 12V. It will
prevent you from network data loss.
2. In some area, installing a surge suppression device may also help to protect your Switch
from being damaged by unregulated surge or current to the Switch or the power adapter if
DC12V power is in use.
3. Consult the network administrator for the information of 802.3af Power over Ethernet.
Port#1 only accept 802.3af power supply, connect with any other non-standard 802.3af
equipments to it may cause the Switch malfunction.
LED Indicators:
PWR/PoE This indicator lights green when the Switch is receiving 12VDC power and lights
orange when receiving 48VDC PoE power, otherwise, it is off.
LNK/ACT This indicator light green when the port is connected to an Ethernet or Fast Ethernet
station, if the indicator is blinking green, it will be transmitting or receiving data on the
network.
