Application scenarios
1. Small and medium-sized enterprises/park offices: high-density access with pure wired computers, servers, and IP phones, limited budget, only requiring basic network functions
2. Monitoring convergence: Non PoE cameras, NVR access, high-speed upstream transmission of video streams
3. Data center edge: Gigabit access for servers/storage, 25GE upstream to core
4. Branches/Branches: Simplified version reduces costs and meets basic networking needs
Introduction
1. High density 48 Gigabit Ethernet port, pure wired high-density access: The 48 Ethernet ports meet the high-density access requirements of pure wired terminals such as office computers, servers, IP phones, and non PoE monitoring, without PoE design, resulting in lower costs
2.25GE high-speed uplink+expansion slot, bandwidth bottleneck free: 8 × SFP28 compatible with 1/2.5/10/25GE, meeting 48 port gigabit aggregation; 1 expansion slot can expand 4 × 25GE, reserved for future expansion
3.1+1 redundancy+high reliability, 7 × 24 stability: 1+1 hot swappable power supply, redundant fan, supporting iStack, VBST, ERPS, VRRP, hot swappable maintenance without interrupting business
4. The basic operation and maintenance are sufficient, and advanced features are added as needed: the basic version meets the requirements of regular park/office networking; If you need cloudification, virtualization, and intelligent operation and maintenance, you can purchase a license upgrade as needed

| Redundant power supply |
1+1 Pluggable AC and DC power modules can be used together on the same device. NOTE:
Power modules with fans and power modules without fans cannot be installed on the same device. |
| Long-term operating temperature [°C(°F)] | –5°C to +40°C (23°F to 104°F) at an altitude of 0-1800 m (0-5905.44 ft.) |
| Short-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 5906 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. |
