Non-flammable wiring parameters (Class I Div.2 environment compatibility)

Configuration guide

1. Hardware installation

Power supply connection: 24V DC redundant power supply is connected through 6-pin terminal block.

Port description:

RJ45 copper cable port (10/100/1000Base-T)

Optical SFP slot (optional single mode/multimode module)

2. Initial setup

Access management interface:

Default IP (need to be initialized through serial port /V.24 interface)

Web login: configure VLAN/QoS through the browser after entering IP.

Key configuration steps:

Redundant ring network settings (HIPER-Ring protocol enabled)

Port mirroring (for flow monitoring)

Firmware upgrade (via SD card or HiVision software)
