Summit X450 Series, X450a Series, and X450e Series
Switches
The Summit X450 series, Summit X450a series, and Summit 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 following Summit option
cards:
Summit XGM-2xn option card, which allows you to add one or two10-Gigabit XENPAK modules
Summit XGM2-2xn option card, which allows you to add one or two 10-gigabit XENPAK modules
Summit XGM2-2xf option card, which allows you to add one or two 10-Gigabit XFP modules
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
Chapter
4, “Summit Option Cards.”
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” on page 42.

Summit X450 Series Switches
The Summit X450 series switches are 24-port switches without PoE options. The ports are implemented
as fixed 10/100/1000BASE-t RJ-45 ports or as installable SFP modules. These switches are available only
with AC internal power supplies.
The Summit X450 series of switches consists of the following switches:
