Ports on the S5731-S24N4X2Q-A

Port Connector Type Description Available Components
100M/1000M/2.5GE BASE-T port (multi-GE port) RJ45 A 100M/1000M/2.5GE BASE-T port (multi-GE port) sends and receives service data at 100 Mbit/s, 1 Gbit/s, 2.5 Gbit/s. If the 2.5 Gbit/s speed is required, the port must use an Ethernet cable of Cat5e or higher category.
10GE SFP+ optical port SFP+ A 10GE SFP+ Ethernet optical port supports auto-sensing to 1000 Mbit/s. It sends and receives service data at 1000 Mbit/s or 10 Gbit/s.
  • GE eSFP optical modules
  • GE-CWDM eSFP optical modules
  • GE-DWDM eSFP optical modules
  • GE SFP copper module
  • 10GE SFP+ optical modules (OSXD22N00 not supported)
  • 10GE-CWDM SFP+ optical modules
  • 10GE-DWDM SFP+ optical modules
  • 1 m, 3 m, 5 m, and 10 m SFP+ high-speed copper cables
  • 3 m and 10 m SFP+ AOC cables
  • 0.5 m and 1.5 m SFP+ dedicated stack cables (only for zero-configuration stacking)
40GE SFP+ optical port QSFP+ A 40GE QSFP+ optical port sends and receives service traffic at 40 Gbit/s.

A 40GE QSFP+ optical port can be split into four 10GE ports.

  • 40GE QSFP+ optical modules
  • 1 m, 3 m, and 5 m QSFP+ high-speed copper cables
  • 10 m QSFP+ AOC cable
  • 2 m QSFP28 dedicated stack cable
Console port RJ45 The console port is connected to a console for on-site configuration. Console cable
ETH management port RJ45 You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely.

You can choose to download the software package through the ETH management port in the BootLoad menu. File transfer through the ETH management port is faster than transfer through the console port.

Ethernet cable
USB port USB 2.0 Type A The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port can only connect to a USB flash drive that complies with USB 2.0.

USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.

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:

  • The operating temperature can exceed 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.
