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
®
wireless 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 8 shows the power supply combinations
required for different PoE needs.

eXpandable Power System (XPS) 2200
The XPS 2200 is the next-generation redundant power system (RPS). It not only provides the functionalities
offered by the RPS but also provides enhanced services with the support for Cisco StackPower technology. When
used with the Cisco Catalyst 3560-X, it provides RPS functionality, but when used with the Cisco Catalyst 3750-X,
it provides StackPower functionality to all the stack members, including power supply redundancy.
The XPS supports dual redundant power supplies and fans. Up to nine switches can be connected to the XPS
2200, and it can provide power backup to two of the failed switches concurrently (when appropriately sized power
supplies are used). The power supplies used by the XPS 2200 are the same as the ones supported in the Cisco
Catalyst 3750-X and 3560-X Series Switches. The XPS 2200 is fully configurable for setting switch priorities in
case of multiple failures.
Please refer to the XPS 2200 Performance Specifications section at the end of this document.

Experience
Borderless Networks, a Cisco architecture, deliver the new workspace experience, connecting anyone, anywhere,
using any device, to any resource securely, reliably, and transparently. Cisco's Borderless Networks architecture
addresses primary IT and business challenges to help create a truly borderless experience by bringing
interactions closer to the employee and customer.
