Summit X450a Series Switches
The Summit X450a series switches are 24-port or 48-port switches without PoE options. The Ethernet
ports are implemented as fixed 10/100/1000BASE-T RJ-45 ports or as installable SFP modules. These
switches are available with either AC or DC internal power supplies. The switch automatically adjusts
to the supply voltage. The internal AC power supply operates from 100 VAC to 240 VAC. The internal
DC power supply operates from -36 VDC to -72 VDC.
The Summit X450a series switches include the following switches:

Summit X450a-24t Switch
The front panel of the Summit X450a-24t switch (Figure 21) includes:
Twenty fixed autosensing 10/100/1000 BASE-T ports (ports 1-20) that provide 20 Gbps of
high-density copper connectivity
Four combination ports (ports 21-24) using RJ-45 connectors and SFPs to provide 4 Gbps of copper
or fiber connectivity
For information about SFPs, see the Extreme Networks Pluggable Interface Modules Installation Guide.
LEDs to indicate port status and switch operating conditions. For a description of the LEDs and their
operation, see “Summit X450, X450a, and X450e Series Switch LEDs” on page 43.
