Summit X440-24p Switch Ports and Slots

The front panel of the Summit X440-24p switch includes:

Twenty-four fixed autosensing 10/100/1000BASE-T PoE+ ports (ports 1–24). The Summit X440-24p switch supports the PoE+ IEEE 802.3a standard and provides up to 30 Watts of power per port. This switch provides a total switch PoE power budget of 380 Watts.
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 Transceivers 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.
