| Model | AR720 |
| First supported version | V300R022C00 |
| Supported Patch Version |
If you want to downgrade a device running V300R022C10SPC100 or a later version to V300R019C10SPC600, V300R019C13SPC200, or V300R021C00SPC200 after the component upgrade, downgrade the device to V300R022C00SPC100 first. If you want to downgrade a device to a version earlier than V300R022C00SPC100 after the component upgrade, set the patch for next startup to the start patch of the target version or a later patch. ( start patch of V300R019C10SPC600 is V300R019SPH380; the start patch of V300R019C13SPC200 is V300R019SPH380; the start patch of V300R021C00SPC200 is V300R021SPH180.) |
| Remarks | When configuring cards, ensure that the total power of the configured cards does not exceed 37 W or contact technical support engineers to obtain more suggestions. |

Ports
Table 3-13 Ports on the AR720
| Port | Connector Type | Description | Available Components |
|---|---|---|---|
| Console interface | RJ45 |
The console interface can connect to an operation terminal for onsite configuration.
|
|
| 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.
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. |
|
| 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.
NOTE: By default, a combo interface works in auto mode and automatically works as an optical or electrical interface. |
The following optical modules are supported: GPON&EPON Optical Modules (Available in V300R023C00 and Later Versions) GE SFP Copper Modules (Available in V300R023C00 and Later Versions) |
| USB 2.0 ports (Host): two USB 2.0 ports | USB 2.0 Type A |
A USB 2.0 interface provides up to 480 Mbit/s upload and download rates.
|
USB 2.0-compliant USB flash drive |
