Summit X440-24t-10G Switch Ports and Slots
The front panel of the Summit X440-24t-10G switch includes:
• Twenty-four fixed autosensing 10/100/1000BASE-T ports (ports 1–24) that provide 24 Gbps of high-
density copper connectivity.
• Four unpopulated SFP ports (ports 21–24) that provide 4 Gbps of
fiber connectivity. The SFP ports
support both 100BASE-FX and 1000BASE-X optical modules.
Ports 21 through 24 are implemented as shared ports that pair a copper port with a fiber port. For
more information about combination ports, see Combination Ports and Failover on page 25.
For information about SFPs, see the Extreme Networks Pluggable Transceivers Installation Guide.
• Two unpopulated SFP+ ports (ports 25 and 26) that provide 20 Gbps of fiber connectivity.
•
Ethernet management port.
• Serial console port implemented as an RJ45 connector, 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 X440 Series Switch LEDs on page
78.
