Ports
| Port | Connector Type | Description | Available Components |
|---|---|---|---|
| 10/100/1000BASE-T PoE+ port | RJ45 |
A 10/100/1000BASE-T Ethernet electrical port sends and receives service data at 10/100/1000 Mbit/s. The port supports the PoE function. |
|
| 1000BASE-X port | SFP | A 1000BASE-X port can send and receive data at 100 or 1000 Mbit/s. |
|
| Console port | RJ45 | The console port is connected to a console for on-site configuration. | |
| 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-L48P4S-A1 has the same types of indicators as the S5735-L48P4X-A1. For details, see the S5735-L48P4X-A1.
Power Supply System
The switch has a built-in AC power module and does not support pluggable power modules. The built-in power module can provide 380 W PoE power, which ensures full PoE power on 24 ports in compliance with 802.3af or on 12 ports in compliance with 802.3at.
Heat Dissipation System
The switch has two built-in fans for forced air cooling. Air flows in from the left side and front panel, and exhausts from the right side.
