To channelize a 40-Gbps port to 4 independent 10-Gbps ports, use the set chassis fpc
slot-number pic pic-
number port port-number channel-speed speed
command. For example, to channelize ports 60 through 62 for a
line card in slot 6:
[edit chassis fpc 6 pic 1]
user@switch# set port 60 channel-speed 10g
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.
[edit chassis fpc 6 pic 1]
user@switch# delete port 60 channel-speed 10g
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 60 on page 116 .
Figure 60: Supported Placement for Copper and Fiber SFP+ Transceivers
CAUTION: When you use the latest OEM part number FCLF8521P2BTL (printed on
the transceiver label), you can install 1GbE transceivers (such as QFX-SFP-1GE-T) in any
port with no restrictions. The same applies for devices that support 10GbE copper
transceivers. However, if you are using the older OEM part number SP7041-M1-JN (not
shipped in last 3+ years) instead, do not install 1GbE copper transceivers (such as QFX-
SFP-1GE-T) directly above or below another 1GbE copper transceiver. Use only the top
row or bottom row to avoid damage to the device caused when the transceivers are
installed above or below each other.
