Port Description
10/100/1000BASE-T port
A 10/100/1000BASE-T
Ethernet electrical port sends and receives service data at 10/100/1000
Mbit/s, and must use an
Ethernet cable.
Table 4-936 describes the attributes
of a 10/100/1000BASE-T Ethernet electrical port.

Console port
The console port is connected
to a console for on-site configuration. The port must use a
console cable. The console port is
used when a switch is powered on for the first time. For details about
the attributes of a console port, see

Mini USB port
The mini USB port is connected
to a console for on-site configuration. When both the Mini USB and
console port have a cable connected, only the Mini USB port works.
ETH management port
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. The port must use an
Ethernet cable. 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.

In V200R012C00 and later versions, you can log in to the switch that contains the ETH management port for the first time through the ETH port. For details, see "First Login to a Switch" in the
Configuration Guide - Basic Configuration. If you have logged in to the device for the first time by pressing and holding the MODE button for 6 seconds or longer and saved the configuration, the default configuration on the ETH port will be cleared. In this case, you cannot log in to the switch for the first time through the ETH port. You are advised to log in to the switch for the first time through the ETH port.
USB port
The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port of the
S5720-EI does not support USB 1.1 and 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.
Indicator Description
The S5720-52X-EI-AC has the same types of indicators as the S5720-32X-EI-AC. For details, see Indicator Description.
Power Supply Configuration
The S5720-52X-EI-AC has a built-in power module and does not support pluggable power modules. It can connect to an RPS1800 power supply for power redundancy.
Figure 4-373 shows the power supply mode of a built-in AC power module. The built-in AC power module (PWR) receives power from an external power source and provides a 12 V output to the chassis.
