Phone Power Requirements
The Cisco IP Conference Phone 8832 can use these power sources:
• Power over Ethernet (PoE) deployment with a Cisco IP Conference Phone 8832 PoE Injector
• Non-PoE Ethernet deployment with a Cisco IP Conference Phone 8832 Non-PoE Ethernet Injector
• Wi-Fi deployment with a Cisco IP Conference Phone 8832 Power Adapter
Table 3: Guidelines for Cisco IP Conference Phone Power
Power Type
PoE power—Provided by either the
Cisco IP Conference Phone 8832
PoE Injector or Cisco IP
Conference Phone 8832 Ethernet
Injector through the USB-C cable
attached to the phone.

Value or Range
IEEE PoE Class 3 via a PoE injector. The phone is
compatible with both IEEE 802.3af and 802.3at switch
blades and supports both Cisco Discovery Protocol
and Link Layer Discovery Protocol - Power over
Ethernet (LLDP-PoE).
Other options include a non-PoE Ethernet injector if
the connected LAN switches don't support PoE. For
WiFi deployment, a Cisco IP Conference Phone 8832
Power Adapter is needed.
Secure boot
USB-C
The Ethernet Specification assumes that the maximum
cable length between each conference phone and the
switch is 100 meters (330 feet).
Guidelines
If you are using either the Cisco IP Conference Phone 8832 PoE Injector
or Cisco IP Conference Phone 8832 Ethernet Injector, make sure that
the switch has a backup power supply to ensure uninterruptible operation
of the phone.
Ensure that the CatOS or IOS version that runs on your switch supports
your intended phone deployment. See the documentation for your switch
for operating system version information.
When you install a phone that is powered by PoE, connect the injector
to the LAN before you connect the USB-C cable to the phone. When
you remove a phone that uses PoE, disconnect the USB-C cable from
the phone before you remove the power from the adapter.
