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
Expansion Modules on page 412.
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 sucient 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 100.

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 RJ45 ports or as installable SFP modules.
These switches are available only with AC internal power supplies.
The Summit X450 series switches include the following models:
• Summit X450-24t Switch Ports and Slots on page 82
• Summit X450-24x Switch Ports and Slots on page 83
