|---|---|---|---|
| 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 port: 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: |
|
USB 3.0 port (host) |
USB 3.0 Type A |
A USB 3.0 interface provides up to 5 Gbit/s upload and download rates.
|
|
|
USB interface 2.0 (host) |
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 |
