1. Two Wi-Fi antenna interfaces

2. Product model silkscreen

3. One USB 2.0 interface

4. WAN interface: VDSL interface

NOTE:

This interface supports the dying gasp function.

5. Ground point

6. One MIC slot

7. RESET button

NOTE:
This button is used to reset the router.
  • In an empty configuration scenario, ensure that the router has no console port input, and has no user login routers. If the Reset button is pressed and held for at least 5 seconds, you will access the registration query center of Huawei devices and obtain the cloud management platform address of routers for plug-and-play deployment.
  • In the configured scenario, hold down the button for at least 5 seconds to restore the factory settings.
  • To reset the router, hold down the button for less than 5 seconds.
Resetting the router will interrupt services. Exercise caution when deciding to press this button.

If needed, you can run the factory-configuration prohibit command in the system view to disable the function of restoring the factory settings by holding down the RESET button. To enable this function again, run the undo factory-configuration prohibit command.

8. One console interface

9. LAN interfaces: eight GE electrical interfaces

10. WAN interfaces: two GE combo interfaces

11. Power socket

12. Jack for power cable locking strap

NOTE:

Insert a power cable locking strap in this jack to secure the power cable.

Ports

Table 3-259 Ports on the AR657W
Port Connector Type Description Available Components
One console interface RJ45

The console interface can connect to an operation terminal for onsite configuration.

  • Standards compliance: RS232
  • Working mode: duplex Universal Asynchronous Receiver/Transmitter (UART)
  • Data equipment type: Data Circuit-terminating Equipment (DCE)

Console cable
LAN interfaces: eight GE electrical interfaces RJ45

A GE electrical interface (10/100/1000 Mbit/s auto-sensing) transmits and receives services at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s.

  • Standards compliance: IEEE802.3, IEEE802.3u, and IEEE802.3ab
  • Working mode: full-duplex (10/100/1000 Mbit/s auto-sensing)
  • Maximum distance: 100 m
NOTE:

GE0 is a management interface and is used for web-based management and email-based deployment.

All LAN-side GE interfaces can be configured as WAN-side interfaces.

Ethernet cable
WAN interfaces: two GE combo interfaces

GE electrical interface: RJ45

GE optical interface: LC/PC

A GE combo interface consists of an optical Ethernet interface and an electrical Ethernet interface on the panel. The two interfaces have only one internal forwarding interface. The electrical and optical interfaces are multiplexed, and only either of them can work at a time. When either of the Ethernet interfaces is working, the other interface is shut down.

  • The GE electrical interface (10/100/1000 Mbit/s auto-sensing) transmits and receives services at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s.
  • The GE optical interface (100/1000 Mbit/s auto-sensing) transmits and receives services at 100 Mbit/s or 1000 Mbit/s.
NOTE:

By default, a combo interface works in auto mode and automatically works as an optical or electrical interface.

GE8 is the BootROM management network port on a device and is used to upgrade the device software through the BootROM menu.
  • GE electrical interface: Ethernet cable
  • GE optical interface: optical module

The following optical modules are supported:

FE SFP&eSFP optical modules

GE eSFP optical modules

GPON&EPON optical modules (supported in V300R023C00 and later versions)
Two Wi-Fi antenna interfaces RP-SMA-K (screw threads outside and a pin inside)

A Wi-Fi antenna interface connects to a Wi-Fi antenna to transmit and receive data.

  • Standards compliance: 802.11a/b/g/n/ac
  • Supported frequency bands: 2.4 GHz and 5 GHz
  • Supported rate: 866.6 Mbit/s
  • MIMO mode (Tx x Rx): 2 x 2
  • Gain: 2.15 dBi/3.0 dBi
NOTE:

If the router uses channels 12 and 13 of the 2.4 GHz band to provide Wi-Fi service, connect an LTE remote antenna to the corresponding LTE antenna interface.

Wi-Fi whip antenna
WAN interface: VDSL interface RJ11

A very-high-speed digital subscriber line (VDSL) interface transmits service data from a LAN to an upstream device at a high speed over a twisted pair.

Standards compliance:
