In addition to the power supplies listed in Table 4, a 440WDC power supply is available as a spare (should be
ordered separately) on all switch models. The DC power supply also delivers PoE capabilities for maximum
flexibility (refer to Table 5 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.

Power over Ethernet Plus (PoE+)
In addition to PoE (IEEE 802.3af), the Cisco Catalyst 3850 Series Switches support PoE+ (IEEE 802.3at
standard), which provides up to 30W of power per port. The Cisco Catalyst 3850 Series Switches can provide a
lower total cost of ownership (TCO) for deployments that incorporate Cisco IP phones, Cisco Aironet
®
wireless
LAN (WLAN) access points, or any IEEE 802.3at-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 6 shows the power supply combinations required for
different PoE needs.
