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.

Ethernet cable

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.

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-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.

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

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 equipment can operate beyond the normal operating temperature range for a short-term period, but the following conditions must be met:

  • The equipment operates at a temperature of over 50°C (122°F) consecutively for at most 96 hours in one year.
  • The equipment operates at a temperature of over 50°C (122°F) for a total of no more than 360 hours in one year.
  • The equipment operates at a temperature of over 50°C (122°F) for no more in 15 times in one year.

The equipment may be damaged or experience unexpected exceptions if any of the preceding limits is exceeded.

The equipment cannot start when the temperature is lower than 0°C (32°F). The maximum distance of optical modules used in these conditions cannot exceed 10 km.
