Two 10GE SFP+ ports

Applicable modules and cables:
NOTE:

If one port uses a GPON optical module, the other port cannot be used.

The locking bar of an optical port is upward. If an optical module cannot be completely inserted into the optical port, do not force it into the port. Turn the optical module 180 degrees and try again.

Four PoE++ 10/100/1000BASE-T ports

3

One USB 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 console port

6

MODE button

NOTE:

The switch supports two indicator modes: status (default mode) and PoE. To change the current indicator mode, press the MODE button.

Hold down the MODE button for 6 seconds and release it to start the web initial login mode. Either of the following situations will occur:
  • If the switch has no configuration file, the system attempts to enter the web initial login mode. In this mode, the status of the PoE indicator is as follows:
    • If the system enters the web initial login mode successfully, the PoE indicator turns green and stays on for a maximum of 10 minutes.
    • If the system fails to enter the initial login mode, the PoE indicator fast blinks for 10 seconds and then restores to the default status.
  • If the switch has a configuration file, the system cannot enter the web initial login mode. In this case, the PoE indicator fast blinks for 10 seconds, and then returns to the default status.

7

AC power input socket

NOTICE:

The external power supply system must be connected to a circuit breaker (20 A is recommended). For safety purposes, do not use a switch without a circuit breaker.

An AC power input socket is used with a power connector, which is included in the installation accessory package delivered with the switch. A power cable needs to be connected to the power connector onsite. If no power cable is available, you can purchase one (part number: 25030398) from Huawei.

8

Fiber management tray (FMT)

NOTE:

The FMT is removable.

A maximum of four fused fibers are supported.

Maximum length of a fiber that can be coiled up in the FMT: 20 m (for a single bare fiber) or 1 m (for a single fiber pigtail). If two fibers are used, this length is halved.

9

Two optical fiber outlets

NOTE:

The diameter of optical fibers supported: 8±0.5 mm to 9.6±0.5 mm (on the left outlet) and 13.3±0.5 mm (on the right outlet).

10

Four Ethernet cable outlets

NOTE:

Cat5e and Cat6 Ethernet cables are supported.

11

Rubber bungs for cable outlets

NOTE:

Rubber bungs must be inserted into the idle cable outlets.

12

NOTE:

The diameter of power cables supported: 9.5±0.5 mm (on the left outlet) and 14±0.5 mm (on the right outlet).

14

AC power output socket 2

NOTE:

The switch provides one 24 V AC output to external devices, such as strobe lights and non-PoE PTZ dome cameras.

One 24 V AC output provides a maximum of 72 W power.

15

DC power output socket

NOTE:

The switch provides two 12 V DC outputs to external devices, such as strobe lights and non-PoE PTZ dome cameras.

Two 12 V DC outputs provide a total of 48 W power. The maximum power of a single output is 48 W.

Two 12 V DC outputs and one 24 V AC output share power resources with PoE output. The total shared power is 150 W.

16

AC power output socket 1

NOTICE:

Cables need to be connected to an AC power output socket onsite. Pay attention to the position of the L and N labels, ensuring that the cables are connected in the correct sockets.

The switch provides 220 V AC power to external devices, such as strobe lights and non-PoE PTZ dome cameras. The maximum output current is 4 A.

The internal 220 V AC power supply is used only for external power conversion. It has no circuit breaker, regulated voltage circuit, or surge protection.

The connected devices must provide certain surge protection capabilities. Recommended values are 20 kA in differential mode and 20 kA in common mode.

17

Latch of the maintenance compartment

NOTE:
  • You need to use the key provided in the installation accessory package to open the door of the maintenance compartment.
  • After the maintenance compartment door is closed, the latch is automatically locked.

18

PE cable ground terminal

NOTE:

It is used to ground a PE power cable for 220 V AC input or output.
