Port Connector Type Description Available Components
10/100/1000BASE-T port RJ45 A 10/100/1000BASE-T Ethernet electrical port sends and receives service data at 10/100/1000 Mbit/s.

Ethernet cable

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.
Console port RJ45 The console port is connected to a console for on-site configuration.

Console 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.

Indicators and Buttons

The S5735-L24T4X-A1 has similar indicators to those on the S5735-L24P4X-A1 except that the S5735-L24T4X-A1 does not have a PoE mode indicator. For details, see the S5735-L24P4X-A1.

Power Supply System

The switch has a built-in AC power module and does not support pluggable power modules.

Heat Dissipation System

The switch has a built-in fan for forced air cooling. Air flows in from the left side and front panel, and exhausts from the right side.

When working properly at a normal temperature, the device meets the desktop-class noise requirements. However, the fan speed may be high and the noise may be loud during device startup.

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