Summit X440-48p Switch Ports and Slots
The front panel of the Summit X440-48p switch includes:
• Forty-eight fixed autosensing 10/100/1000BASE-T PoE+ ports (ports 1–48). In addition to 48 Gbps
of high-density copper connectivity, these ports also provide a full 30 Watts of PoE+ per port. This
switch provides a total switch PoE power budget of 380 Watts.
• Four unpopulated SFP ports (ports 45 – 48) that provide 4 Gbps of fiber connectivity. The SFP ports
support both 100BASE-FX and 1000BASE-X optical modules.
Ports 45 through 48 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.
• 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 X440-48p switch (Figure 64 on page 77) 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. See Installing an
EPS-C2 Power Supply on page 380 for more information.
• AC power input socket.
The internal AC power supply operates from 100 VAC to 240 VAC.
