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
● Summit X450a-24t-TAA Switch
● Summit X450a-24tDC Switch
● Summit X450a-24tDC-TAA Switch
● Summit X450a-24x Switch
● Summit X450a-24x-TAA Switch
● Summit X450a-24xDC Switch
● Summit X450a-24xDC-TAA Switch
● Summit X450a-48t Switch
● Summit X450a-48t-TAA Switch
● Summit X450a-48tDC Switch
● Summit X450a-48tDC-TAA Switch
NOTE
In the descriptions that follow, references to a Summit X450a series model number also apply to the equivalent
TAA-compliant switch version.
Summit X450a-24t Switch
The front panel of the Summit X450a-24t switch (Figure 31) 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 more information about combination ports, see “Combination Ports and Failover” on page 16.
For information about SFPs, see the Extre me Ne two rks Plugg a ble Inte rfa c e Mo dule s Ins ta lla tio n G uide .
● 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 58.
