Ports

Table 3-253 Ports on the AR651W-X4
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: four 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)

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:

A combo interface works in auto mode and automatically works as an optical or electrical interface by default.

GE4 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
LAN interfaces: three 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
  • Frequency bands supported: 2.4 GHz/5 GHz
  • Rate: 450 Mbit/s (2.4 GHz); 1300 Mbit/s (5.0 GHz)
