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.
