Application scenarios
1. High density Wi Fi 6/7 access layer in the park: equipped with high-power APs to meet wireless coverage in conference rooms, high-density office areas, and dormitories
2. High power access for security monitoring: drives 4K/8K ball cameras, panoramic cameras, PoE++direct supply, 25GE uplink without congestion
3. Comprehensive access for enterprises/parks: carrying wireless, wired, IP telephone, IoT, monitoring, and unified network management
4. Small data center/branch aggregation/core: three-layer routing+high-speed uplink to meet the core requirements of small networks
Introduction
1. High power PoE+power supply: single port 90W, whole machine 1000W, directly drives Wi Fi 7 high-density AP, ball machine/panoramic IPC, high-power IoT devices, without external power supply, simplifying wiring.
2.25GE high-speed uplink: 8 × SFP28, solves the bottleneck of high-density wireless/monitoring high traffic, and adapts to "gigabit access, 25GE aggregation/core" networking.
3. Expansion and Stacking: 1 expansion slot+iStack intelligent stacking (up to 9 virtual units per unit), unified management, cross device link aggregation, and flexible expansion.
4. Layer 3+Virtualization: IPv4/IPv6 dual stack, static/RIP/OSPF, supporting VxLAN to the edge, achieving multi service integration, cross regional networking, and reducing operation and maintenance costs.
5. High reliability and security: N+1 power redundancy, intelligent fans, hardware QoS, ACL, port security, iPCA2.0 network quality detection, MACsec end-to-end encryption.

| Long-term operating temperature [°C(°F)] | –5°C to +45°C (23°F to 113°F) at an altitude of 0 to 1800 m (0 to 5905.44 ft.) |
| Short-term operating temperature [°C(°F)] | -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.) |
| 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. |
