Review your configuration and issue the commit command.
If you want to return the port to the default, delete the speed statement from the configuration at the
[chassis fpc 6 pic 1 port port-number] hierarchy level and commit the configuration. The network port is
reset to the default 40-Gigabit Ethernet interface.

Using Copper and Fiber SFP Transceivers
When you configure the 10-Gigabit Ethernet ports 0 to 59 as 1-Gigabit Ethernet ports, you can use optical
fiber SFP transceivers in any of the ports. However, copper SFP transceivers are restricted to the lower
two rows. See Figure 63 on page
Figure 63: Supported Placement for Copper and Fiber SFP+ Transceivers
CAUTION:
line card.
Because 1 Gbps copper SFP transceivers are physically larger than optical SFP transceivers, there is
insufficient room for 3 copper SFP transceivers to be stacked. Use the top row only for optical SFP
transceivers. You can stack copper transceivers in the bottom two rows. Ports are arranged belly-to-belly.
Stacking three SFP transceivers in a column can damage the line card. For the recommended configuration,
see Figure 64 on page 142.
