Cisco Catalyst 3650 | PWR-C2-640WDC= Catalyst 3650 DC Power Supply 640W

Cisco Catalyst 3650 Series

Switch Models and Corresponding Default Power Supplies

The multigigabit switches support a different set of power supplies than the non-multigigabit switches. In addition the PWR-C1-350WAC is not supported on the multigigabit switches. In addition to the power supplies listed in Table 3, a 640W DC power supply is available at the time of order or as a spare on all non-multigigabit switch models. The DC power supply also delivers PoE capabilities for maximum flexibility (refer to Table 4 for available PoE budget with DC power supplies). 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.

Available PoE with DC Power Supply

Power over Ethernet Plus (PoE+)

The Cisco Catalyst 3650 Series Switches support both PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at standard), which provide up to 30 W of power per port. 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. The 3650 Series can provide a lower TCO for deployments that incorporate Cisco IP phones, Cisco Aironet^® wireless LAN (WLAN) access points, or any IEEE 802.3at-compliant end device. Table 5 shows the power supply combinations required for different PoE needs.

Minimum Power Supply Requirements for Full PoE and PoE+

Cisco Universal Power over Ethernet (Cisco UPOE)

Cisco UPOE is a breakthrough technology, offering the following services and benefits:

●   60W per port to enable a variety of end devices such as Samsung VDI client, BT IP turret systems in trading floors, Cisco Catalyst compact switches in retail and hospitality environments, personal Cisco TelePresence^® systems, and physical access control devices

●   High availability for power and guaranteed uninterrupted services, a requirement for critical
applications (e911)

●   Lower OpEx by providing network resiliency at lower cost by consolidating backup power into
the wiring closet

●   Faster deployment of new campus access networking infrastructures by eliminating the need for a power outlet for every endpoint

The Cisco UPOE capability is available only on select multigigabit models.
