AC input power socket

NOTE:

It must be used with the Phoenix connector, which is included in the installation accessory package.

2

Monitoring port

NOTE:

It must be used with the Phoenix connector, which is included in the installation accessory package.

The monitoring port detects the status of external devices, for example, monitoring the opening and closing of the cabinet door.

For details about how to use a monitoring port, see "Monitoring Interface Configuration" in the CLI-based Configuration Guide - Device Management Configuration Guide.

3 One console port 4 One PNP button
NOTICE:

To restore the factory settings and reset the switch, hold down the button for at least 6 seconds.

To reset the switch, press the button.

Resetting the switch will cause service interruption. Exercise caution when you press the PNP button.

5 One USB port 6 Eight 10/100/1000BASE-T ports
7 Four 10GE SFP+ ports 8 Ground screw
NOTE:
It is used with a ground cable.

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 4-647 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.

Working mode

10/100/1000 Mbit/s auto-sensing

Maximum transmission distance

It supports long-distance interconnection with Huawei cameras. For example, it supports the distance of 200 m at 100 Mbit/s and supports the distance of 250 m at 10 Mbit/s.
  • The supported camera models are M2220-I, M2221-FL, M2221-VL, M2260-I, and M2220-I(8-32mm).
  • If the transmission distance exceeds 100 m, Category 5E or higher Ethernet cables are required.
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 4-648 describes the attributes of a 10GE SFP+ Ethernet optical port.

Default value: 9600 bit/s

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 S5720I-12X-SI-AC has similar indicators to those of the S5720I-12X-PWH-SI-DC except that the S5720I-12X-SI-AC does not have a PoE mode indicator. For details, see Indicator Description.

Power Supply Configuration

The S5720I-12X-SI-AC has a built-in power module and does not support pluggable power modules.

Figure 4-254 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.
