Summit X440-L2-48t Switch
The front panel of the Summit X440-L2-48t switch (Figure 51) includes:
● Forty-eight fixed autosensing 10/100/1000BASE-T ports (ports 1–48) that provide 48 Gbps of
high-density copper connectivity
● 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 22.
For information about SFPs, see the Extreme Networks Pluggable Interface Modules Installation Guide.
● Ethernet management port
● Serial console port implemented as an RJ-45 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 77.

The rear panel of the Summit X440-L2-48t switch (Figure 52) includes:
● 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. See
“Installing an EPS-C2 Chassis” on page 322 for more information.
● AC power input socket
The internal AC power supply operates from 100 VAC to 240 VAC.
