Unpacking Information
Thank you for purchasing this product. Before
installation, please verify that your package
contains the following items:
1. One Gigabit Ethernet Switch ALL-
SG8205PD
2. Rubber feet *4
3. User Manual
4. One DC power adapter (optional)
5. One power cord (optional)
Introduction
General Description
The device is a powerful, high-performance
Gigabit Ethernet Switch, with all 5 ports capable of
10/100/1000Mbps auto-negotiation operation
(NWay), which means the switch could
automatically negotiate with the connected
partners on the network speed and duplex
mode. It is ideal for micro-segmenting large
networks into smaller, connected subnets for
improved performance, enabling the
bandwidth demanding multimedia and

5
imaging applications. Moreover, the
10/100/1000Mbps auto-sensing ability
provides an easy way to migrate 10/100Mbps
to 1000Mbps network with no pain.
This switch supports PoE pass-through,
having both PD (Powered Device) and PSE
(Power Sourcing Equipment) features in one
single device, which means the switch could
get power from the PD port by connecting to
a PSE device and supply power on the 2
PSE ports for connected devices via CAT 5e
or better twisted cables. By integrating the
data transmitting cable and power cord, it
eliminates the effort constructing your
network. You could easily connect a Wireless
AP or a VoIP phone (PD devices) to this
switch without looking outlets for them. Over
current protection and circuit shorting
protection are also supported to ensure the
safety.
The switch is plug-n-play without any
software to configure and also fully compliant
with all kinds of network protocols. Moreover,
the rich diagnostic LED indicators on the
front-panel provide the operating status of
individual port and whole system.

green LED indicates a valid
data connection from the
uplink port.
PoE LED
It indicates the PoE
connection status of the port

LED indicates that a valid
PD device is connecting to
the PoE port, while a
blinking LED indicates no
valid PD device been
connected to the PoE port.
LNK/ACT
LED
- Steady green: Valid port
connection.
- Blinking green: Valid port
connection and there is data
transmitting/ receiving.
- Off: Port disconnected.
The Rear Panel
There are a DC jack for external power
adapter (optional) and 5 Ethernet ports for
local switching on the rear panel. All Ethernet

Installation
Before installing the switch, we strongly
recommend:
1. The switch is placed with appropriate
ventilation environment. A minimum
25mm space around the unit is
recommended.
2. The switch and the relevant components
are away from sources of electrical noise
such as radios, transmitters and
broadband amplifiers.
3. The switch is away from environments
beyond recommend moisture.
Steps of Installation
1. Attach the provided robber feet to the
bottom of the switch to keep the switch
from slipping. The recommend position
has been square-marked.
2. Install the switch on a level surface that
can support the weight of the unit and
the relevant components.

12
3. Plug the switch with the Ethernet Cable
on the PD port, which is connecting to a
PSE or Plug the female end of the power
adaptor on DC Jack to get power.
Network Cables Installation
1. Crossover or straight-through cable:
All the ports on the switch support Auto-
MDI/MDI-X functionality. Both straight-
through or crossover cables can be used
to connect the switch with PCs as well
as other devices like switches, hubs or
router.
2. Category 3, 4, 5, 5e or 6 UTP/STP
cable: To make a valid connection and
obtain the optimal performance.
Appropriate cables corresponding to
different transmitting/receiving speed is
required. To choose a suitable cable,
please refer to the following table:

Application Scenario
The following diagrams display the
recommended installation. However you may
combine such applications according your
plan on network topology.
Application 1:
You may connect any port of this switch to a
work station, a PC, a laptop, a router or a
NAS via the RJ-45 LAN cables, if the external
power supply is connected:

15
Application 2:
You may connect the Uplink/PD port of this
switch to a PoE switch or PoE injector via the
RJ-45 LAN cable.
In such application, the external power
adapter won’t be necessary, but the total
output power of the PoE ports 1~2 will be
limited and depend on the power getting from
the Uplink/PD port:
