Cisco 8832 connectivity?

Does a new 8832 Conference phone supposed to come with a LAN or power injector. We are POE,however doesn't it need some sort of Ethernet injector or brick? The phone I received had nothing in the box with it. Is the injector/brick ordered separate?.....Thanks,

Re: Cisco 8832 connectivity?

Hi there


●   Power over Ethernet (PoE): A Cisco IP Conference Phone 8832 Ethernet Injector is required. Please order CP-8832-K9, CP-8832-W-K9, CP-8832-EU-K9, CP-8832-EU-W-K9 or CP-8832-NR-K9, which includes the Ethernet injector inside the base package.


Before You Begin


Ensure that you have the latest firmware version installed on your Cisco Unified Communications Manager. Check for updated device packages here:




Step 1   Choose the power source for the phone:
  • Power over Ethernet (PoE) using either the Cisco IP Conference Phone 8832 PoE Injector or the Cisco IP Conference Phone 8832 Ethernet Injector. North American users can use either injector. Outside North America, users must use the Cisco IP Conference Phone 8832 PoE Injector.


  • Non-PoE using the Cisco IP Conference Phone 8832 Ethernet Injector and a power adapter.


For more information, see Ways to Provide Power to Your Conference Phone.

Step 2   Connect the phone to the switch.
  • If you use PoE:
    1. Plug the Ethernet cable into the LAN port.


    2. Plug the other end of the Ethernet cable into either the Cisco IP Conference Phone 8832 PoE Injector or the Cisco IP Conference Phone 8832 Ethernet Injector.


    3. Connect the injector to the conference phone with the USB-C cable.


  • If you do not use PoE:
    1. Plug the power adapter into the electrical outlet.


    2. Connect the power adapter to the Cisco IP Conference Phone 8832 Ethernet Injector using a USB-C cable.


    3. Plug the Ethernet cable into the Ethernet injector.


    4. Plug the Ethernet cable into the LAN port.


    5. Connect the Ethernet injector to the conference phone using a second USB-C cable.




Hope this helps!

Re: Cisco 8832 connectivity?

I don't think that answers the question. 


I think what you are saying is the "spare part" model doesn't include a power source of any kind, for example:


CP-8832-EU-W-K9 is bundled with an Ethernet injector or an 18W power adapter (to be determined at order time)

CP-8832-EU-W-K9= has just the unit itself


The problem is that the datasheet doesn't really make it clear what the different adapters do or what regions they are necessary for. I assume that most folks already have switches supplying 15w for 802.11af class 3, so presumably no wall power socket is necessary. Some photographs on the datasheet would help.


I'm in a position to buy all the options and hopefully find out, but it's a bit wasteful.

Re: Cisco 8832 connectivity?

It says something about pick one of the options when you order the non spare part. If you pick that part on CCW it asks you to configure it with a power source.

The spare doesn’t come with any power adapter like you note, and the unit has only USB-C so we are back to boxes and bricks to power these, even with PoE. That’s for sure unexpected if you don’t read closely.

Re: Cisco 8832 connectivity?

Yes, I also noticed that on CCW, ordering the non-spare part code forces you to buy a power source, but I'm still bewildered by what each component does. These are the part codes mentioned on the datasheet:


PWRCLIP-EU -> Snap-in wall power adapter for continental EU (not sure about Switzerland)


The user guide provides some diagrams on four possible ways to power these phones, but the terms "PoE Injector", "Ethernet Injector", "Non-PoE Ethernet Injector" and "Ethernet Injector with the Ethernet power option" don't really help.


Since the majority probably have switches supporting 802.3af/Class3 (15.4w), I believe no wall-power is necessary (unless daisy-chaining two units). Do you know what would be the correct part codes for this case?





P.S. My assumption is that the CP-8832-POE is for those who have 802.3af/Class3 capable switches and a regional combination of CP-8832-ETH-WW plus PWRCLIP-EU is for those without poe capable switches.

Re: Cisco 8832 connectivity?


We order the CP-8832-POE for this which is a grey rectangular brick that plugs into the Ethernet, and has a USB-C jack. It comes with a USB-C cable to connect to the phone. I worry that the brick will get lost when moving the phone around and have ordered a spare but it is what it is.

>From my internal documentation:

The Cisco 8832 can be powered from PoE, which is the recommended model to minimize daisy chains, and the number of cables.

Order part CP-8832-POE= (stocked) for the PoE / USB-C power adapter, with USB-C cable.

Part CP-8832-PWR= only provides power for use with Wi-Fi connectivity (not used, not stocked).

Part CP-8832-ETH= (not stocked) allows for Ethernet with external AC power.

I remember taking a minute to try and figure out what these do. As far as European power, it's possible that the wall part that comes with the ETH and PWR models (or the worldwide, the data sheet makes some comment about this) is a switching supply that takes the clip on pins to work with whatever locale the power is ordered in. The ATAs I believe are like this.

The data sheet says "compatible with 802.3af and 802.3at" which is not really a good way to describe the device. I have a couple powered by the POE brick now, it reads as a Class 3 budgeting for 13.9W with CDP. Power detail shows it's drawn 9.0 peak and 7.0 idle but I don't know how much they've been used or at what volume level.

I think you'd do just fine with the -POE part.

Awesome answer, thank you Adam.
