Introduction
Switch Description
HGW-2402A-PSE is an Industrial Gigabit Smart Unmanaged PoE switch with 24
10/100/1000Mbps PoE ports and 2 Gigabit SFP uplink ports. HGW-2402A-PSE can
deliver PoE power to end devices such as IP cameras, wireless AP/bridge devices
or IP phones. Switch has DIP switch settings for 4 distinctive operating modes. In AI VLAN
mode switch has all 24 ports isolated from each other, to prevent network storms and
improve network performance. In AI Extend mode, the effective transmission of the 24 UTP
ports can reach up to 250 meters, improving network deployment options. Third option, the
AI power supply mode, detects the status of the connected PD devices and will automatically
restart the device by cycling PoE delivery to correct status of unresponsive PD elements.
Last mode, the AI QoS mode treats video data with preferential higher priority to maintain
video quality in event of traffic congestion. HGW-2402A-PSE supports IEEE802.3af/at and
auto PD identification to protect remote devices that do not follow IEEE standards, like non-
standard PoE passive devices or non-PoE devices.

RJ45 Ports
HGW-2402A-PSE delivers PoE power on 24 ports of 10/100/1000Mbps following IEEE802.3af
and IEEE802.3at standards. When set up in Extend mode (via DIP switches), port 1 to 24 can
support 250m line PoE power at 10M speed only.
SFP Ports
HGW-2402A-PSE has two gigabit SFP ports (25, 26) requiring Gigabit rated SFP modules.
DIP Switch Mode Settings

5
Extend Mode: Ports 1-24 port support 250 meters long spans (cabling must be cat 5 or
above, speed will only be 10M for the UTP ports)
VLAN Mode: Ports 1-24 are isolated from each other, reducing risk of network storms
and improving overall network performance
QoS Mode: Identify type of data and prioritize traffic for video data to enhance video
quality
AI PoE Mode: Automatic detection of enabled PoE ports with stalled data traffic and
execute a power cycle to restart the PD device and restore communication
IMPORTANT –Multiple DIP switches can be active in the same time for a combination of
features to be present and operating

Power Terminal Block
6 screw power terminal block offers PWR1 and PWR2 DC48V input for HGW-2402A-PSE
switch; power supply requirement is DC 48-56V(no power switch to eliminate accidental
shutdown).
Ground Terminal Screw
For surge protection and accidental electric discharges please ALWAYS use proper
electric grounding.

Installation
Warning：Incorrect usage of this device can cause property damage and personal injury,
please read carefully the list below before using the equipment:
⚫Please keep device unplugged from power sources during installation, wear
anti-static bracelet if available
⚫Please make sure that power source voltage matches requirements for power
input on the equipment
⚫To avoid electric shock, please do not open the PoE Switch case when in
operation
⚫Before cleaning the PoE switch, please disconnect power cables
⚫Avoid cleaning switch with a wet cloth, avoid using liquids for cleaning, use a
light damp or dry cloth to wipe dust from device

Dustproof
Dust deposits can increase static electricity charges and cause electrostatic
discharges that can destroy component parts of the PCB. To avoid static electricity
discharge effect, keep equipment in a clean indoor area and regularly clean device
of dust deposits
Electromagnetic interference
Electromagnetic interference can affect the normal operation of the network
device. In order to reduce electromagnetic interference please keep equipment
away from high frequency power sources or high current devices such as wireless
charging pads.
Lighting protection
In order to protect equipment from inadvertent electrical surges, please provide
good electrical grounding for the installation rack, please observe proper network
cabling installation and always use lightning surge protectors when networking
cabling is installed outside of a building.

Installation
HGW-2402A-PSE switch is designed to be installed on a standard TS-35 DIN rail.
Installation on rail should follow below diagram.
For wall mounting the position of the wall brackets should change as above.
1. Note：
Before screwing the screws into the wall, make sure that the screw size
matches the wall-mounting metal panels of the HGW-2402A-PSE switch. In
total, 4 screws are required for wall mounting.

8
Connectivity
3.1 RJ45 port connections
Connect regular network equipment or PoE PD devices to any UTP ports 1 to 24 like in
below diagram.

9
Warning：
Length of UTP cable should not exceed 100m (305ft) for any network device that is
not a PoE PD device.
All RJ45 ports support Auto-MDI/MDIX, both standard Ethernet cables and crossover
Ethernet cables can be used for network connectivity (please use Cat5e cabling or
better)
3.2 SFP ports
HGW-2402A-PSE SFP ports only support gigabit SFP modules. Please use Gigabit rated
(1.25G) SFPs with the switch.
Installing the SFP transceiver module：
1. Hold the SFP module from the side, insert it smoothly along the SFP port slot of
PoE switch, until a soft click is heard, denoting SFP is secure to switch;
2. Observe proper Rx and Tx path connectivity for each inserted SFP
3. Check the corresponding link indicator light status. If light is on, link has been
established, if light is off, no link has been made over the fiber.
Warning：
Avoid sharp turns of fiber cables, keeping the radius of any turn larger than 4 inches;
Be prepared to clean fiber connector ferrules if there is trouble obtaining a fiber link;
Avoid looking into the SFP of fiber connectors while under operation, lasers can cause
serious eyes damage
3.3 Device Initialization
Power up will turn PWR1/PWR2 LEDs ON. After approximately 2 seconds all other LED
indicators on switch will turn briefly ON and then OFF again. This is part of the internal
POST process of the device. After the brief OFF period (another approx. 2 seconds),
all LEDs will report the correct status of connectivity and PoE.
Switch will start operating normally.
