V200R002C00 to V200R012C00 versions

This model does not match V200R003C02, V200R003C10, V200R005C00SPC500, V200R005C01, V200R005C02, V200R005C03, or V200R007C10.

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 4-113 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.
Table 4-113 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

10GE SFP+ 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 4-114 describes the attributes of a 10GE SFP+ Ethernet optical port.
Table 4-114 Attributes of a 10GE SFP+ port



Connector type


Optical port attributes

Depend on the optical module used

Standards compliance


Working mode

GE/10GE auto-sensing

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 4-115.
Table 4-115 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

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.

Indicator Description

The S5700-52X-LI-DC has the same types of indicators as the S5700-28X-LI-AC. For details, see Indicator Description.

Power Supply Configuration

The S5700-52X-LI-DC 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 4-45 shows the power supply mode of a single DC power module. The built-in DC power module (PWR) receives DC power from an external power source and provides a 12 V output to the chassis.

NEG: negative cable

RTN: positive cable

GND: 12 V reference ground

Heat Dissipation

The S5700-52X-LI-DC has two built-in fans for forced air cooling. The airflow direction is left-to-right.

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