Brief introduction
Many thanks for purchasing this Gigabit Ethernet POE
Switch! This product supports IEEE802.3ab 1000Base-T
standard, available for both full duplex and half duplex mode.
It provides 8 UTP ports with PoE feature, suitable for most
10/100/1000M networks.
Installation
1. Interface
RJ-45 interface
All RJ-45 copper interfaces support Auto-Negotiation for
optimal speed detection through RJ-45 CAT5 UTP cables
with a maximum length of 100 meters (or 328 feet). They
also support standard Auto-MDI/MDI-X that can detect the
type of connection to any Ethernet device without requiring
special straight or crossover cables.
2. Connection
All ports support 802.3af compliant Power Devices (PD) and
other network devices (e.g. work station, hub or switch).
Connect one end of the standard UTP CAT5 network cable
to the 10/100/1000Mbps RJ-45 ports on the front panel of
the switch. Connect the other of the cable to the typical
network devices.
3. Power on
Connect one end of the power adapter to the switch.Connect
the power plug of the adapter to a standard wall outlet. When
the switch is powered on, the PWR LED should be remain
static green. The LEDs of each port indicate the connection
status of corresponding port. (See Table.1 for detailed
description)

Warning:
1. This product is suitable for indoor application.
2. The cable distance between the switch and PC should not
exceed 100 meters for UTP cable.
3. Cat.3/4/5 cable may be used in 10Mbps operation.
However, Cat.5 UTP or better data grade cable must be
employed for 100/1000Mbps operation.
4. The appliance inlet is used as the disconnect device and
shall remain readily operable at all time.
Trouble shooting:
1. Bad performance
Please check the transfer rate (10Mbps, 100Mbps or
100Mbps) and the duplex status (full duplex or half
duplex) of both sides. Make sure both sides are set to
identical status.
2. Link failure :
Check the L/A LED on the switch try another port on
the switch make sure the cable is well installed make sure
the cable is the right type power off the device for a while
and power it on again.
