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 4-1128 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.

10GE SFP+ optical port

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. Table 4-1129 describes the attributes of a 10GE SFP+ Ethernet optical 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 Table 4-1130.

Default value: 9600 bit/s

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. Table 4-1131 describes the attributes of an ETH management 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 switch for the first time by pressing and holding the MODE button for 6 seconds or longer and save 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 can only connect to a USB flash drive that complies with USB 2.0.
NOTE:
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 S5731-S24P4X has the same types of indicators as the S5731-S48P4X. For details, see Indicator Description.

Power Supply Configuration

The S5731-S24P4X is a PoE switch. It has two power module slots, each of which can have a 1000 W PoE power module installed. Table 4-1132 lists its power supply configurations.

NOTE:
When a switch has two power modules installed, the two power modules work in redundancy mode to provide power for the chassis and in load balancing mode to provide power for PDs.
Figure 4-457 shows the power supply mode of dual AC PoE power modules (PWR1 and PWR2). After AC power is transmitted to the PWR modules, the PWR modules provide 56 V outputs. The outputs are combined on the motherboard, which then provides 12 V voltage for the switch and 56 V voltage for the PDs.

Heat Dissipation

The S5731-S24P4X uses pluggable fan modules for forced air cooling. Air flows in from the front side and exhausts from the rear panel.
