NOTE:
The monitoring port monitors the cabinet door, power module, battery power, and power supply of the air conditioner.

Port Description

100/1000BASE-X port
A 100/1000BASE-X port can send and receive data at 100 Mbit/s or 1000 Mbit/s. Table 4-993 describes the attributes of a 100/1000BASE-X port.

Working mode

100/1000 Mbit/s 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 4-994.

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 4-995 describes the attributes of an ETH management 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 S5700-28C-HI-24S has similar indicators (except service port indicators) to those on the S5700-28C-HI. For details, see Indicator Description.

Power Supply Configuration

The S5700-28C-HI-24S uses pluggable power modules. It can be configured with a single power module or double power modules for 1+1 power redundancy. Pluggable AC and DC power modules can be used together in the same switch.

Figure 4-396 shows the power supply connections of dual DC power modules. After DC power is transmitted to the PWR module, the PWR module provides 12 V output voltage, and the motherboard provides power for the entire device.

NEG: negative cable

RTN: positive cable

GND: 12 V reference ground

Figure 4-397 shows the power supply connections of dual non-PoE AC power modules. After AC power is transmitted to the PWR module, the PWR module provides 12 V output voltage, and the motherboard provides power for the entire device.

Heat Dissipation

The S5700-28C-HI-24S has three built-in fans for forced air cooling. The airflow direction is left-to-right.

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