ExtremeSwitching X670-G2-48x-4q Switch Ports and Slots

X670-G2-48x-4q switch ports and slots include:

• 48 fixed autosensing 10GBASE-X SFP+ ports (ports 1-48) that provide 10 Gbps high-density fiber connectivity. Two of these ports are configurable as stacking ports.
• Four 40GBASE-X unpopulated QSFP+ ports (ports 49, 53, 57, and 61 in unpartitioned 40G mode or ports 49 to 64 in partitioned 10G mode) that provide 40 Gbps of fiber connectivity. Of these four ports, two (using SummitStack-V160) or all four (SummitStack-V320) can be configured as stacking ports.
• Ethernet management port (10/100/1000BASE-T).
• Serial console port implemented as an RJ45 connector used to connect a terminal and perform local management.
• Front panel USB port.
• Rear dual PSU power slots with front-to-back or back-to-front airflow.
• Three rear slots for fan modules with front-to-back or back-to-front airflow.
• Two rear panel mini-BNC connectors labeled OUT for connecting a Building Integrated Timing Supply (BITS) or GPS timing source:
  • 1 PPS frame output
  • 10 MHz output
