Introduction
1. U+N hybrid PoE design (core differentiation)
24 ports simultaneously compatible with PoE++(90W) high-power power supply and pure 2.5G high-speed non PoE data port
Flexible allocation: Some ports are connected to Wi Fi 7 APs, 4K panoramic dome cameras, and facial recognition turnstiles (90W); Partial port connection to 2.5G desktop PC, server (pure data, no PoE loss)
Addressing the pain points of mixed scenarios that require both high-power PoE and pure high-speed data access
2.2.5G+25GE Full High Speed Architecture
Downstream 2.5G adaptive: compatible with Wi Fi 7 AP and 2.5G network card terminals, with a bandwidth 2.5 times higher than gigabit
Upstream 8 × 25GE: Thoroughly solving the bottleneck of high-density wireless/video traffic uplink, supporting "gigabit/2.5G access, 25GE aggregation" networking
3. Three layers+virtualization+high reliability
Supports IPv4/IPv6 dual stack, static/RIP/OSPF, VxLAN, meeting the requirements of multi service isolation and cross network segment interoperability in the campus
IStack intelligent stacking (up to 9 units), unified management, cross device link aggregation, simple expansion and operation and maintenance
N+1 power redundancy SmartLink/VRRP、MACsec、iPCA2.0, Ensure business stability 24/7
4. Security and QoS
802.1X authentication ACL、 Port security, terminal access, meeting security/intranet compliance requirements
Hardware level QoS and multicast optimization ensure priority of video, voice, and data services

| Restriction on the operating temperature variation rate [°C(°F)] |
When the altitude is 1800–5000 m (5906–16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.). The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met:
If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur. Devices cannot start when the temperature is lower than 0°C (32°F). The maximum transmission distance of an optical module used for short-term operation at 50°C (122°F) cannot exceed 10 km. |
