Summit X440-24tDC Switch Ports and Slots

The front panel of the Summit X440-24tDC 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.

For information about SFPs, see the Extreme Networks Pluggable Interface Modules Installation Guide.
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.
