All 32 QSFP+ ports on the switch are configured for 40-Gigabit Ethernet only. All ports
are supported as access or uplink ports, but cannot be channelized.
When a 100-Gbps transceiver is inserted into QSFP28 ports

CAUTION:
In release Junos OS Release 17.2R1, changing the system mode
causes the FPC to reboot. Because there can be a slight loss of data while
the FPC reboots, we recommend that you only configure the changes during
a maintenance window for this release.
CAUTION:
Take care when changing the channelization mode from Flexi-pic
to default. If you have existing ports that are channelized in Flexi-pic mode,
remove the channelization from the interface before changing the system
mode. Changing the Flexi-pic mode to the default mode with channelized
