Summit X460 Series Switches
The Summit X460 series switches are 24-port or 48-port switches that provide Ethernet connectivity
using fixed 10/100/1000BASE-T RJ45 ports or installable SFP or SFP+ optical modules.
Two Summit X460 models support the PoE+ IEEE 802.3at standard and provide up to 30 Watts of
power per port. These models provide a total switch PoE power budget of 380 Watts with a single
installed power supply and 760 Watts with two installed power supplies.
Four of the Summit X460 models include ports that support Synchronous Ethernet. Five models have
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 can be used to connect the system to a parallel
management network for administration. Alternatively, you can use an Ethernet cable to connect this
port directly to a laptop to view and locally manage the switch configurations. The Ethernet
management port supports 10/100/1000 Mbps speeds.
The rear panel of the switch provides slots for installing the Summit option cards listed in the following
table. These port option cards allow you to add high-speed data ports or stacking ports to the switch.
Summit X460 series switches require an ExtremeXOS version of at least 12.5.1 but not greater than 16.x.

Cooling is provided by a replaceable fan module. Two power supply bays accommodate either an AC or
DC power supply; the PoE-capable models require a specific AC power supply. For more information
about the power supplies used in the Summit X460 switches, see Replaceable Internal Power Supplies
on page 185.
