LPU–NSQ1GT8C40
Ethernet interface introduction
NSQ1GT8C40 provides eight electrical interfaces (10Base-T/100Base-TX/1000Base-T) and four
Combo interfaces. A Combo interface consists of an electrical interface and an optical interface. The
default operating interface is the electrical interface.
z
For the interface speed and duplex mode of electrical interfaces and the Combo interfaces
operating in electrical interface mode, see Table 1-20.

The electrical 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. For the description
of the electrical interface LEDs, refer to Table 1-7.
z
The optical interface of a Combo interface supports 1000 Mbps in full duplex mode. It has an
interface LED on the right of the optical interface, indicating the status of the SFP optical interface.
For the description of the optical interface LEDs, refer to Table 1-7.
For a Combo interface, either the electrical interface or the optical interface can operate at one time.
You can use the
combo enable
{
copper

fiber
} command in interface view to switch between the
electrical and optical interfaces. For details about the
