Summit X440-24t Switch Ports and Slots
The front panel of the Summit X440-24t 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 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 on page
78.
• Stack number indicator.

The rear panel of the Summit X440-24t switch (shown in Figure 40 on page 62) includes:
• Two high-performance stacking ports with associated LEDs.
• Redundant power input connector for optional connection to the EPS-C2 External Power Module.
The connecting redundant power supply cable is shipped with the power module unit. For more
information, see Installing an RPS-500p Redundant Power Supply on page 396 or Installing an EPS-
C2 Power Supply on page 380.
• AC power input socket.
The internal AC power supply operates from 100 VAC to 240 VAC.
