Where To Go Next - Cisco Catalyst 3850 Hardware Installation Manual

Switch Installation
PoE inline power supports devices compliant with the IEEE 802.3af standard, as well as prestandard Cisco
IP Phones and Cisco Aironet Access Points. Each port can deliver up to 15.4 W of PoE. PoE+ inline power
supports devices compliant with the IEEE 802.3at standard, by delivering up to 30 W of PoE+ power per port
to all switch ports.
See Power Supply Modules
on 24- and 48-port switches.
Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are
made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection
methods, unless the exposed metal parts are located within a restricted access location and users and service
people who are authorized within the restricted access location are made aware of the hazard. A restricted
access area can be accessed only through the use of a special tool, lock and key or other means of security.
Statement 1072
Warning Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted.
After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the
emergency calling service. In the USA, this emergency number is 911. You need to be aware of the emergency
number in your country. Statement 371
Caution Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a
suitable and safe earth ground before connecting them to the switch or other devices.
Caution
Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling
to connect Cisco prestandard IP Phones and wireless access points, IEEE 802.3af, or 802.3at (PoE+)-compliant
devices. You must remove any cable or device that causes a PoE fault.

If the default configuration is satisfactory, the switch does not need further configuration. You can use any
of these management options to change the default configuration:
• Start the Network Assistant application, which is described in the getting started guide. Through this
• Use the CLI to configure the switch as a member of a cluster or as an individual switch from the console.
• Use the Cisco Prime Infrastructure application.
• If you are using Cisco IOS XE Denali 16.1.x and later releases, see the Configuring the Switch chapter
OL-26779-05
for the power supply modules required to support PoE, PoE+, and Cisco UPOE
GUI, you can configure and monitor a switch cluster or an individual switch.
in this guide for information about setting up the switch.
