USB portUSB 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.

USB flash drive

ETH management portRJ45

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.

Indicators and Buttons

The S5731-S48T4X has similar indicators to those on the S5731-S48P4X except that the S5731-S48T4X does not have a PoE mode indicator. For details, see the S5731-S48P4X.

Power Supply System

The switch can use a single power module or two power modules for 1+1 power redundancy. Pluggable AC and DC power modules can be used together in the same switch. However, the power modules with fans and power modules without fans cannot be installed on the same switch.

Heat Dissipation System

The switch has two built-in fans for forced air cooling. Air flows in from the left, right, and front sides, and exhausts from the rear panel.

This figure only shows the airflow direction and does not depict the actual device.

  • 0.5 m and 1.5 m SFP+ dedicated stack cables (only for zero-configuration stacking)

Console portRJ45The console port is connected to a console for on-site configuration.

Console cable

USB portUSB 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.

USB flash drive

ETH management portRJ45

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.

  • When you press this button a third time, the service port indicators restore to the default mode and show the connection status and link activity of each service port.

If you do not press the MODE button within 45 seconds, the service port indicators restore to the default mode. In this case, the SPEED indicator is off.

NOTE:
Hold down the mode switch button for 6s and release it to start the web initial login mode. Either of the following situations will occur:
  • If the switch has no configuration file, the system attempts to enter the web initial login mode. In this mode, the status of mode indicators is as follows:

    • If the system enters the web initial login mode successfully, all mode indicators turn green and stay on for a maximum of 10 minutes.

    • If the system fails to enter the initial login mode, all mode indicators fast blink for 10 seconds and then restore the default status.

  • If the switch has a configuration file, the system cannot enter the web initial login mode. In this case, all mode indicators fast blink for 10s, and then return to the default states.
