Table 7-409 Functions of the ET1D2L02QSC0
Function Description

Basic function

  • Provides two 40GE optical ports for data transmission and line-rate switching.

  • Allows a 40GE port to split into four 10GE ports.

Distributed forwarding

Performs concurrent data forwarding using a distributed data plane.

Hot swapping

The ET1D2L02QSC0 is hot swappable.


A 40GE network can be established by installing 40GE cards on aggregation switches and core switches, as shown in Figure 7-186.

Figure 7-186 40GE cards deployed on a campus network

A 40GE network with 40GE cards deployed has the following advantages:

  • Provides higher bandwidth.
  • Is compatible with 10GE networks because a 40GE interface can be split into four 10GE interfaces. This feature enables customers to seamlessly upgrade their 10GE networks to 40GE networks.
  • Has a higher efficiency and lower packet loss ratio than a 40GE network established by bundling four 10GE lines for load balancing.

The 40GE cards are used on networks that need to provide high bandwidth, for example, video surveillance bearer networks and high-definition (HD) video conference bearer networks. The following uses an HD video conference bearer network as an example to describe application of 40GE cards.

Transmission of HD video and voice flows consumes high bandwidth on a network, especially on the aggregation layer and core layer. The bandwidth of aggregation and core devices usually becomes a bottleneck on an HD video conference bearer network. As shown in Figure 7-186, 40GE cards are deployed on the aggregation layer and core layer to transmit HD video and voice flows faster, more efficiently, with fewer packets lost. This deployment ensures sufficient bandwidth for the HD video conference bearer network and delivers high quality HD images and voice.

Indicators and Ports

Blinking: The port is transmitting and receiving data.




Steady on: A link has been established on the port.


RUN/ALM: running status indicator


Steady on: The card has been powered on, but the software is not running.

Slow blinking: The card software is running properly.

Fast blinking: The card software is starting.


Steady on: The card has failed and the fault requires manual intervention.


Steady on: The card is powered off. (For example, the card has been forcibly powered off using the power off command or is about to start.)
