4. Hardware Introduction
4.1 Front Panel
The front panel of the 802.3at PoE+ switch consists of 9
auto-sensing 10/100/1000Mbps Ethernet RJ45 ports. The LED
indicators are also located on the front panel of the 802.3at
PoE+ switch.
GSD-908HP
Figure 4-1: GSD-908HP Switch Front Panel
The front panel of 802.3at PoE+ switch provides one DIP
switch for “Default” or “VLAN” mode selection. The detailed
descriptions are shown in the following table.
DIP Switch Mode Function
This mode makes the 802.3at PoE+
Default
Switch operate as a general switch and all
ports operate at 10/100/1000Mbps autonegotiation.
This mode makes the 802.3at PoE+ Switch
operate as a VLAN isolation switch and
VLAN
port 1 to port 8 will isolate respectively.
Port 1 to port 8 can only communicate
with port 9 (uplink port).

4.3 Rear Panel
The rear panel of the 802.3at PoE+ switch comes with a
DC power socket that accepts 55V DC input power and a
grounding terminal that protects the 802.3at PoE+ Switch
against lightning strikes.

Step 4: Connect your 802.3at PoE+ Switch to 802.3af/802.3at
complied powered devices (PD) and other network
devices.
A. Connect one end of a standard network cable to
the 10/100/1000 RJ45 ports on the front panel of
the 802.3at PoE+ Switch.
B. Connect the other end of the cable to the network
devices such as printer servers, workstations,
router, etc.

1. The device is a power-required device, which
means it will not work till it is powered. If your
networks should be active all the time, please
consider using UPS (Uninterrupted Power Supply)
for your device. It will prevent you from network
data loss or network downtime.

Notice
2. In some areas, installing a surge suppression
device may also help to protect your 802.3at
PoE+ Switch from being damaged by
unregulated surge or current to the 802.3at
PoE+ Switch or the power adapter.

Step 5: Supply power to the 802.3at PoE+ Switch.
A. Connect one end of the power cable to the DC
power adapter and connect its DC plug connector
to the 802.3at PoE+ Switch.
B. Connect the power plug of the power cable to a
standard wall outlet.
When the 802.3at PoE+ Switch receives power, the Power LED
should remain solid amber.
