Cisco 3750-X and 3560-X Series Switches Power Supply Requirements for PoE, PoE+ and UPOE Models

The Cisco Catalyst 3750-X and 3560-X Cisco Switches are an enterprise-class lines of stackable and standalone switches, respectively. These switches provide high availability, scalability, security, energy efficiency, and ease of operation with innovative features such as Cisco StackPower (available only on the Catalyst 3750‑X), IEEE 802.3at Power over Ethernet Plus (PoE+) configurations, optional network modules, redundant power supplies, and Media Access Control Security (MACsec) features.

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 and UPOE, which provides 60W of power per port (only on UPOE-capable models). 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. Cisco UPOE switches extend the IEEE 802.3 PoE+ standard to double the power per port to 60 watts. UPOE-enabled ports can be used to deliver power for all current PoE/PoE+ solutions in addition to UPOE devices, including VDI clients, IP turrets for financial trading, personal Cisco TelePresence systems, and more. The maximum UPOE budget available on the Cisco Catalyst 3750-X/3560-X switch is 1800W per switch. This requires the 1100W AC power supply in both the power supply slots. 1800W in POE budget makes sure that the 24-port models support full UPOE on all ports (24 x 60W/port = 1440W) and the 48-port models support up to 30 UPOE connections (30 x 60W/port = 1800W) per switch.

Power Supply Requirements for PoE/PoE+ and UPOE models

POE/POE+	24 Port PoE Switch	48 Port PoE Switch
PoE (15.4W per port)	One C3KX-PWR-715WAC	One C3KX-PWR-1100WAC or Two C3KX-PWR-715WAC
PoE+ (30W per port)	One C3KX-PWR-1100WAC or Two C3KX-PWR-715WAC	Two C3KX-PWR-1100WAC or One C3KX-PWR-1100WAC and one C3KX-PWR-715WAC
UPOE (60W per port)	One C3KX-PWR-715WAC and one C3KX-PWR-1100WAC or Two C3KX-PWR-1100WAC	One C3KX-PWR-715WAC and one C3KX-PWR-1100WAC or Two C3KX-PWR-1100WAC
