Dual Redundant Modular Power Supplies

The Cisco Catalyst 3750-X Series and 3560-X Series Switches support dual redundant power supplies. The switch
ships with one power supply by default, and the second power supply can be purchased at the time of ordering the
switch or at a later time. If only one power supply is installed, it should always be in the power supply bay 1.
Figure 5.
Table 4 shows the different power supplies available in these switches and available PoE power.

In addition to the above power supplies a 440W DC power supply is available as a configurable option on all switch
models. The DC power supply also delivers 175W of PoE for maximum flexibility, and customers can mix and match
the AC and DC power supplies in the two available power supply slots. Any of these power supplies can be installed
in any of the switches.

Power over Ethernet Plus (PoE+)

In addition to PoE 802.3af, the Cisco Catalyst 3750-X and 3560-X Series Switches support PoE+ (IEEE 802.3at
standard), which provides up to 30W of power per port. The Cisco Catalyst 3750-X and 3560-X Series Switches can
provide a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet
LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to
each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise
be necessary in IP phone and WLAN deployments. Table 5 shows the power supply combinations required for
different PoE needs.
