Device Overview
The device is a layer-2 commercial switch designed for video stream transmission. It features a full-metal design for heat dissipation and supports various work modes via DIP switches. It is suitable for homes, offices, and server farms.


- PoE Support: Complies with IEEE802.3af/at standards. Red ports support Hi-PoE and IEEE802.3bt; orange ports support Hi-PoE.
- Extend Mode: Allows PoE transmission up to 250m at 10 Mbps.
- PoE Watchdog: Real-time detection of terminal device status.
Installation
The device supports rack mounting. Attach the mounting brackets to the side panels using the provided screws, then secure the device to the rack.


- Ensure the device is installed on a solid, flat surface.
- Maintain at least 10 cm of clearance on the sides and top for heat dissipation.
- Do not block the ventilator.
Wiring
Proper wiring is critical for device safety and performance.


- Grounding: Always connect the ground terminal to a ground bar to protect against lightning and interference.
- Power: Connect the power cord to the rear power port (100–240 VAC). Ensure the device is grounded before powering on.
- Ethernet: Use standard RJ-45 cables. The device supports MDI/MDI-X self-recognition.
- SFP Module: Install SFP modules carefully. Do not touch the gold fingers. Unplug optical fibers before inserting the module.
- PoE Connection: Connect PoE-enabled terminal devices directly to the PoE ports. Maximum distance is 100m (or 250m in Extend mode).
Quick Operation
Access the device management interface via a web browser.
- Connect your computer to the switch.
- Enter 192.168.1.110 in your browser.
- Log in with the username 'admin' and set your password during the first initialization.
Cybersecurity Recommendations
To ensure network security, follow these mandatory actions:
- Use Strong Passwords: Minimum 8 characters, including mixed character types.
- Update Firmware: Keep firmware up-to-date to receive security patches.
- Physical Protection: Restrict physical access to the device.
- Network Security: Disable unnecessary services (SNMP, SMTP, etc.), enable HTTPS, and use IP/MAC address filtering.
