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 different 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.

The rear panel of the switch has an option slot to accommodate one of the Summit port option cards listed in the following table.

Option card compatibility depends on the specific switch series. See the individual switch descriptions for the option card supported on each switch. For option card installation instructions, see Installing Port Option Cards and VIMs.

Two high-speed stacking ports allow you to combine multiple units into a single SummitStack management entity.

Power connectors include an AC or DC power input socket and a redundant power connector. (See specific switch descriptions for more information about the power options.) The switch automatically adjusts to the supply voltage. The redundant power connector allows you to connect the switch to the an external power supply. When a compatible external power supply is used with the Summit X450, X450a, or X450e series switch, the internal and external power supplies are fully fault tolerant. For most switches, if one power supply fails, the other power supply will provide sufficient power to operate the switch. For information about power supply redundancy with the Summit X450a-48p switch, see Summit X450e-48p Power Supplies.
