3850 Series 12-Port SFP IP Base Ethernet Managed Network Switch
WS-C3850-12S-S
The Cisco Catalyst 3850 Series provides capabilities that ideally
suited to support the convergence of wired
and wireless access. The new Cisco Unified Access Data Plane (UADP)
Application-Specific Integrated
Circuit (ASIC) powers the switch and enables uniform wired-wireless
policy enforcement, application visibility,
flexibility, and application optimization. This convergence is
built on the resilience of the new and improved Cisco
StackWise-480 technology.
The Cisco Catalyst 3850 Series Switches support full IEEE 802.3at
Power over Ethernet Plus (PoE+), Cisco
Universal Power Over Ethernet (Cisco UPOE), modular and
field-replaceable network modules, RJ-45 and
fiber-based downlink interfaces, and redundant fans and power
supplies.

The Cisco Catalyst 3850 Series Switches support dual redundant
power supplies.The switch ships with one power
supply by default, and the second power supply can be purchased at
the time of ordering the switch or at a later time.
If only one power supply is installed, it should always be in power
supply bay 1. The switch also ships with three
field-replaceable fans. (See Figure 7.)
