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:

  For information about QSFP+ optical modules, see the Extreme Networks Pluggable Transceivers Installation Guide.

• Groups of two or four ports configurable to be stacking ports as shown in the following table:
  

  X770 Stacking Method and Ports

  Stacking Method	Ports
  SummitStack-V	103 and 104
  SummitStack-V160	103 and 104
  SummitStack-V-320	101 and 103, 102 and 104

  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.
• Stack number indicator.
