Introduction

Network Access Switch S5731-S8UM16UN2Q Enterprise Switch with 8 Port 7

1.10G+2.5G dual rate+PoE++full coverage 8-port support 100M/1/2.5/5/10G five rate, compatible with 10G servers, 10G network card computers, 10G Wi Fi 7 APs; 16 ports support 100M/1G/2.5G triple rate, compatible with 2.5G Wi Fi 6/6E AP and 2.5G NAS; All electrical ports support PoE++(90W), which directly drives high-power terminals without the need for additional power supply. 2. High bandwidth uplink, flexible networking 2 × 40GE QSFP+uplink, supporting 40G splitting (4 × 10G), meeting the high traffic uplink requirements after high-density 10G/2.5G terminal access; Support port mode switching (optional 12 × 10G+12 × 2.5G+4 × 10G SFP+) to adapt to different networking requirements. 3. N+1 power redundancy, high reliability with 3 power slots, supports N+1 redundancy, avoids business interruption caused by single point power failure, suitable for core access/aggregation nodes with high reliability requirements. 4. Enrich the second/third layer and security features Second layer: STP/RSTP/MSTP, ERPS (50ms ring network switching), 4K VLAN, IGMP Snooping; Layer 3: OSPF, ISIS, VRRP, IPv4/IPv6 dual stack; Security: 802.1X/Portal, DHCP Snooping, ARP anti spoofing, DoS protection; Operations: iStack intelligent stacking (up to 9 units), zero configuration deployment, Web/CLI/SSHv2 management.

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: The operating temperature exceeds 45°C (113°F) for a maximum of 96 consecutive hours in a year. The total time when the operating temperature exceeds 45°C (113°F) in a year is less than or equal to 360 hours. The number of times the operating temperature exceeds 45°C (113°F) is less than or equal to 15 in one year. 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 cannot exceed 10 km.
