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.
