Summit X250e-48p Switch Ports and Slots
The front panel of the Summit X250e-48p switch includes:
• Forty-eight fixed autosensing 10/100BASE-T PoE ports (ports 1–48). In addition to 4.8 Gbps of high-
density copper connectivity, these ports provide a full 15.4 Watts of PoE per port when used with the
EPS-600LS External Power Module.
• Two combination ports (ports 49–50) using RJ45 connectors and SFPs to provide 2 Gbps of copper
or fiber connectivity.
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.
• LEDs to indicate port status and switch operating conditions.
For a description of the LEDs and their operation, see Summit X250e Series Switch LEDs on page
43.
• Stack number indicator showing the position of this switch in a stacked
configuration.
• Serial console port used to connect a terminal and perform local management.

• Two high-performance stacking ports with associated LEDs.
• Redundant power input connector for use with one or more EPS-600LS External Power Modules
(Model No. 10913) installed in an EPS-C chassis (Model No. 10912).
The connecting redundant power supply cable is shipped with the EPS-C chassis. The PoE capability
of the Summit X250e-48p switch varies depending on the number of external power modules in use.
For more information, see EPS-600LS External Power Module on page 170.
• AC power input socket.
The internal AC power supply operates from 100 VAC to 240 VAC.
