Connect your phone
Get your phone ready by installing the components and get it connected to the network and power.
The phone register process varies with deployment ways. Your phone may get registered automatically when you connect it to the network. Otherwise, you must get the activation code from your administrator to register your phone.
Use the information in this section to connect your phone in a wired network.
Your phone supports Power over Ethernet (PoE). If your network supports PoE, an Ethernet connection powers up your phone and connects it to the network. You don't have to connect the shipped power adapter.
1 |
Connect the shipped handset to the handset port.
|
2 |
Insert the foot stand to the slots on the back of the phone. The foot stand is designed for two tilt angles. Try both tilt angles to find the best position for your viewing preferences. To switch to the other angle, unplug the foot stand, flip it over, and reinsert it to the slots.
|
3 |
Connect your phone to the network with the shipped Ethernet cable. If your network supports PoE, your phone powers up when you connect it to the network. Otherwise, go to the next step to connect the power adapter.
|
4 |
(Optional) Connect your phone to a power socket with the power adapter that you purchased separately from Cisco. Your phone boots up automatically when it connects to the power source.
If your network supports PoE, skip this step.
|
What to do next
Follow the steps in this section to connect your phone in a wireless network.

|
3 |
Connect your phone to a power socket with the shipped power adapter.
Your phone boots up automatically when it connects to the power source.
|
4 |
Press Start on the Welcome screen. |
5 |
Choose your wireless network from the list, enter the username and password, and press Apply. |
What to do next
Register your phone
Depending on how your administrator configures your phone on the call control system, you might use one of the following methods to register your phone:
- Method 1: No action is required during the phone registration. The registration is done automatically.
- Method 2: A 16-digit activation code is required during the phone registration. You can get it from your administrator in advance. Enter the activation code when you are prompted for it.
- Method 3: An alternate TFTP server address is required if your phone is missing a TFTP address. You can get it from your administrator when this situation occurs. You need to manually enter the alternate TFTP server to continue the registration.
By default, 802.1X authentication is disabled on your phone.
If your network uses the 802.1X protocol, ensure that you enable 802.1X authentication on your phone by accessing
. Otherwise, your phone will fail to connect to the network.Your phone gets registered automatically when it boots up and connects to the network. In this scenario of auto registration, you don't need to enter any input as the whole registration proceeds automatically.
Before you begin
- You have turned on your phone.
- Your administrator has configured your phone on the call control system.
