Combo interfaces
1) Introduction
The A6602 provides four Combo interfaces. Each Combo interface consists of an electrical
Ethernet interface and an optical Ethernet interface, but either the electrical Ethernet interface
or the optical Ethernet interface can operate at one time.
Each fixed electrical Ethernet interface supports 10/100/1000 Mbps auto-sensing. For the rate
and duplex for the electrical Ethernet interfaces, see
Table 1-14 Rate and duplex for the electrical Ethernet interfaces
10 Mbps (auto-sensing)
100 Mbps (auto-sensing)
1000 Mbps (auto-sensing)
The electrical Ethernet interface LEDs are above the RJ-45 ports. The LEDs in triangle and
inverted triangle indicate the status of the lower and upper electrical Ethernet interfaces,
respectively.
Each optical Ethernet interface supports a rate of 1000 Mbps in full-duplex mode. The optical
Ethernet interface LEDs are in the middle of the four Combo interfaces and use separate LEDs
to indicate the status of the corresponding SFP interfaces.

For a Combo interface, the default operating interface is the Ethernet electrical interface.

For a Combo interface, you can use either the electrical Ethernet interface or the optical

Ethernet interface. You can use the combo enable { copper | fiber } command in interface
view to switch between the optical and electrical Ethernet interfaces.
For details about the combo enable { copper | fiber } command, refer to HP SR6600 Routers
