Application scenarios
1. Enterprise/park office: high-density office computers, servers, IP phones with pure wired access, 25GE upstream to aggregation, reserved expansion slots for expansion
2. Monitoring/security convergence: ordinary IP cameras (non PoE), NVRs and other devices are connected to transmit video streams at high speed upstream
3. Small and medium-sized enterprises/branches: integrated pure wired access+expansion capability, simplifying network architecture and reducing operation and maintenance costs
4. Data center edge: Gigabit access for servers and storage devices, 25GE upstream to the core
Introduction
1. High density 48GB electrical port, pure wired high-density access
48 full gigabit electrical ports, suitable for high-density access of pure wired terminals such as office computers, servers, IP phones, and ordinary monitoring, without PoE design, suitable for scenarios that do not require power supply and only require data transmission, reducing equipment costs.
2.25GE high-speed uplink+expansion slot, bandwidth bottleneck free, flexible expansion
8 SFP28 optical ports are compatible with 1/2.5/10/25GE, meeting the high bandwidth aggregation after 48 ports of gigabit access; One expansion slot can accommodate 4 × 25GE optical cards, reserving space for future terminal/bandwidth expansion and adapting to multi service fusion networking.
3.1+1 high reliability redundancy, 7 × 24 stable operation
1+1 hot swappable redundant power supply, fan redundancy, supports iStack stacking, link aggregation VBST、ERPS、VRRP， Eliminate single point of failure; Hot swappable maintenance does not interrupt business and meets the high availability requirements of enterprise/park core access.
4. Intelligent operation and maintenance+cloud based security, simplifying management
Operations: iPCA network quality perception, Telemetry telemetry, Netstream, OPS programmable, supports iMaster NCE unified management, zero configuration deployment
Security: MACsec, NAC, ACL, anti attack, secure boot, ensuring access and transmission security
Virtualization: VxLAN/EVPN/SRv6, adapted to cloud based parks and multi service fusion networking

| 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. |
