Table 3-478 USB interface attributes
Attribute Description
Connector type TYPE-A
Standards compliance USB 2.0
Working mode Host
GE combo interface
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 one of them can work at a time.
When one of the Ethernet interfaces is working, the other interface is shut down.
l 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.
l The GE optical interface (100/1000 Mbit/s auto-sensing) transmits and receives services
at 100 Mbit/s or 1000 Mbit/s.
NOTE
l In V200R008C30 and earlier versions, a combo interface works as an electrical interface and uses a
network cable to transmit and receive data by default.
l In V200R008C50 and later versions, a combo interface works in auto mode and automatically works as
an optical or electrical interface by default.
DO interface
The DO interface provides output signals to instruct the connected device to perform required
actions.
Table 3-479 describes DO interface attributes.
Table 3-479 DO interface attributes
Attribute Description
Connector type 3-pin Phoenix terminal block
Signal type Passive DO, Boolean value (short circuit
and open circuit)
Cable type 6.2.2 3-Pin Phoenix Connector (DO)
ETH interface
The ETH interface is used to log in to the route to perform configuration and management.
Table 3-480 lists the attributes of the ETH interface.
