• The QDD-400G-ZR transceiver can be installed in the top 12 QSFP56-DD ports and 10
bottom QSFP56-DD ports.
• The QDD-400G-ZR-M transceiver can be installed in the top 12 QSFP56-DD ports and 6
bottom (in separate 1x2 cages) QSFP56-DD ports.
• We Recommend that you install the top ports with QDD-400G-ZR or QDD-400G-ZR-M
transceivers before installing the bottom ports.
• Temperature derating due to altitude does not occur.
Table 2 on page 10 describes the maximum number of ports for each interface type supported by the
QSFP56-DD ports.

NOTE: Port speeds are configured using the set interfaces
You configure ports to operate at a particular speed by using the appropriate speed option. If you
configure a port to operate at a certain speed, and you want to return the port to the default
configuration, delete the speed statement from the configuration at the [interfaces
hierarchy level and commit the configuration. The network port is reset to the default Ethernet
interface.
