Summit X770-32q Switch Ports and Slots
The front panel of the Summit X770-32q switch includes:
32 40-gigabit Ethernet ports capable of supporting passive
copper QSFP+ and active fiber QSFP+.With quad fan-out SFP+
cables, the QSFP+ ports can be partitioned into 10-gigabit data lanes: 24 of the
ports can be partitioned into four 10-gigabit data lanes, and the remaining
eight ports can be used as single 10-gigabit data lanes. This yields a total of
104 10-gigabit ports as shown in X770 Port Numbers for 10G mode and 40G
Mode :

When ports are used for stacking they are not available for normal Ethernet
connectivity. For more information about stacking, see Building Stacks .
Management port (10/100/1000-Mbps).
Front panel USB port for access to external storage.
RJ45 RS-232c serial console port used to connect a terminal and
perform local management.
LEDs to indicate port status and switch operating conditions.
For a description of the LEDs and their operation, see Summit X770 Series Switch LEDs .
