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 4-733 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.
Table 4-733 Attributes of a 10/100/1000BASE-T Ethernet electrical port



Connector type


Standards compliance

IEEE802.3, IEEE802.3u, IEEE802.3ab

Working mode

10/100/1000 Mbit/s auto-sensing

Maximum transmission distance

100 m

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 4-734.
Table 4-734 Attributes of a console port



Connector type


Standards compliance


Working mode

Duplex Universal Asynchronous Receiver/Transmitter (UART)

Baud rate

9600 bit/s, 19200 bit/s, 38400 bit/s, 57600 bit/s, or 115200 bit/s

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 BootROM menu. File transfer through the ETH management port is faster than transfer through the console port. For details on how to use the ETH management port, see the Configuration Guide - Basic Configurations. Table 4-735 describes the attributes of an ETH management port.

Indicator Description

The S5700-52C-PWR-EI has the same types of indicators as the S5700-28C-PWR-EI. For details, see Indicator Description.

Power Supply Configuration

The S5700-52C-PWR-EI is a PoE switch. It has two power module slots, each of which can have a 500 W or 250 W power module installed. A power module can provide 369.6 W or 123.2 W of PoE power for powered devices (PDs). Table 4-736 lists its power supply configurations.

Table 4-736 Power supply configurations
Power Module 1 Power Module 2 Available PoE Power Maximum Number of Ports (Fully Loaded)
250 W 123.2 W
  • 802.3af (15.4 W per port): 8
  • 802.3at (30 W per port): 4
500 W 369.6 W
  • 802.3af (15.4 W per port): 24
  • 802.3at (30 W per port): 12
250 W 250 W 246.4 W
  • 802.3af (15.4 W per port): 16
  • 802.3at (30 W per port): 8
500 W 500 W 739.2 W
  • 802.3af (15.4 W per port): 48
  • 802.3at (30 W per port): 24
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 4-293 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 12 V and -53 V outputs. The outputs are combined on the motherboard, which then provides 12 V voltage for the switch and -53 V voltage for the PDs.

Heat Dissipation

The S5700-52C-PWR-EI uses pluggable fan modules for forced air cooling. Air flows in from the left and right sides, and exhausts from the rear panel.

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