Overview
The Industrial Ethernet models listed above are high performance and reliability Ethernet switches. All Industrial models are hardened for -40 to
+75℃ operation and have 6KV surge protection on all ports. Largest configuration of the unmanaged models is 8 copper and 2 fiber ports. All PoE models deliver 30W per each UTP port supporting 802.3at PoE+ standard. Reliability is highly ranked with an MTBF exceeding 120,000 hours. All Industrial Ethernet models listed in this manual have passed IEC standards as described in the Technical Specifications table.
Package includes DIN rail mounting bracket, Wall bracket, screw block power connector and one User Manual.
required by the unit to avoid risk of wires overheating and any risk of fire. This is especially important for the PoE PSE equipment. As general rule, please keep power wiring on a different path from data cables and avoid crossing wires. This will reduce the risk of power surges on data ports.

DIN rail mounting procedure
All Industrial switches from HGW series have DIN rail bracket mounted from factory to the rear panel of the unit. If Wall mounting is needed, please first remove the DIN rail bracket. If DIN rail bracket needs to be reattached, please make sure the spring is located on top position when unit is vertical.
- Step 1
Please hold unit as in below image, making sure top of bracket with spring falls onto the top edge of TS-35 DIN rail - Step 2
Rotate and snap the unit onto the DIN rail by pushing the bottom unto the TS-35 DIN rail. Unit will be secured to rail.

Front DIP Switch
| DIP | State | Description |
| #1 | ON | RSTP Disabled |
| OFF | RSTP Enable | |
| #2 | ON | Port VLAN Enable |
| OFF | Port VLAN Disable | |
| #3 | ON | SFP Port is 100M |
| OFF | SFP Port 100/1000M | |
| #4 | Function Reserve |
NOTE:
- When RSTP switches to the ON position, it indicates RSTP is in disabled status.
- When VLAN switches to the ON position, it indicates VLAN is enabled. All LAN ports can only communicate with the SFP uplinks when this option is enabled.
- To enable the changed configuration of DIP Switch function, please reboot the Ethernet switch after tuning the DIP switch.
Top panel has terminal screw block for PWR1 and PWR2 input as well as Alarm Relay output and M3 grounding screw.
Note: For PSE models 48V input is required.
Alarm Relay wiring
The alarm relay is closed during normal operation. If a Fault is encountered (like power supply input lost) then relay contacts become open until fault is remedied
Power input wiring
There are two independent and redundant power inputs, marked PWR1 and PWR2. Please observe voltage polarity when wiring power to the screw block connector. Please complete wiring without hot wires and with screw block connector disconnected from switch.
Installation warning
Please make sure of proper electrical grounding availability before powering up device. The unit should be grounded using either the M3 grounding screw or making sure the DIN rail installation or wall mount brackets are correctly grounded. Make sure power wires have adequate gauge for the power
