Summit X450, X450a, and X450e Series Switches
The Summit X450, X450a, and X450e series switches provide 24 or 48 Ethernet ports.
These switches deliver high-density fast Ethernet connectivity using fixed 10/100/1000BASE-T ports or
installable small form pluggable (SFP) optical modules. Models in dierent series are available both with
and without PoE and in AC or DC power versions.
Each Summit X450, X450a, or X450e series switch has four combination ports that provide
10/100/1000 BASE-T or SFP connectivity for 4 Gbps of copper or fiber connectivity. A serial console
port on the front panel allows you to connect a terminal and perform local management. An Ethernet
management port on the back panel can be used to connect the system to a parallel management
network for administration. Alternatively, you can use an Ethernet cable to connect the Ethernet
management port directly to a laptop to view and locally manage the switch configurations.
