This chapter helps you install the Cisco Unified IP Phones on an IP telephony network.

Note	Before you install a Cisco Unified IP Phone, you must decide how to configure the phone in your network. Then you can install the phone and verify the functionality. For more information, see Cisco Unified IP Phones and Telephony Networks.

Before you install the Cisco Unified IP Phone, review the requirements in these sections:

The Cisco Unified IP Phones include these components on the phone or as accessories for the phone:

The Cisco Unified IP Phone Expansion Module can be attached to Cisco Unified IP Phone to extend the number of line appearances or speed dial buttons. You can customize the button templates for the Cisco Unified IP Phone Expansion Module to determine the number of line appearances and speed-dial buttons. See the phone button template section for the applicable phone model for details.

Note	The Cisco Unified IP Phones 7971G-GE and 7970G support only the Cisco Unified IP Phone Expansion Module 7914.

Note	The Cisco Unified IP Phone 7945G does not support the Cisco Unified IP Phone Expansion Modules.

You can attach one or more Cisco Unified IP Phone Expansion Modules to the Cisco Unified IP Phone 7975G and 7965G by using one of the following methods:

• When you initially add the phone to Cisco Unified Communications Manager, select

  • 7914 14-Button Line Expansion Module for the Cisco Unified IP Phone Expansion 7914

  • 7915 12-Button Line Expansion Module or 7915 24-Button Line Expansion Module for the Cisco Unified IP Phone Expansion Module 7915

  • 7916 12-Button Line Expansion Module or 7916 24-Button Line Expansion Module for the Cisco Unified IP Phone Expansion Module 7916 in the Module 1 or Module 2 fields, and choose the appropriate expansion module firmware. See Step 6 in the following procedure.

• Attach the expansion module after the phone is configured in Cisco Unified Communications Manager.

You can attach a Cisco Unified IP Phone Expansion Module 7914 to the Cisco Unified IP Phone 7971G-GE and 7970G by using one of the following methods:

• When you initially add the phone to Cisco Unified Communications Manager, choose 7914 14-Button Line Expansion Module in the Module 1 or Module 2 fields and then choose the appropriate expansion module firmware. See Step 6 in the following procedure.

• Attach the expansion module after the phone is configured in Cisco Unified Communications Manager.

The Cisco Unified IP Phone includes an adjustable footstand. When you place the phone on a desktop surface, you can adjust the tilt height to several different angles in 7.5 degree increments from flat to 60 degrees. You can also mount these phones to the wall by using the footstand or by using the optional locking wall mount kit.

To adjust the footstand, push in the footstand adjustment button and adjust the tilt.

You can secure the Cisco Unified IP Phones to a desktop with a laptop cable lock. The lock connects to the security slot on the back of the phone, and the cable can be secured to a desktop.

The security slot can accommodate a lock that is up to 20 mm wide. Compatible laptop cable locks include the Kensington laptop cable lock and laptop cable locks from other manufacturers that can fit into the security slot on the back of the phone.

After the Cisco Unified IP Phone has power connected to it, the phone begins its startup process by cycling through these steps.

1. These buttons flash on and off in sequence:

   • Headset (Only if the handset is off-hook when the phone powers up. In this case, hang up the handset within 3 seconds or the phone launches its secondary load instead of its primary load.)
   • Mute
   • Speaker

2. Some or all of the line keys flash orange.

   Caution

   If the line keys flash red in sequence after flashing yellow, do not power down the phone until the sequence of red flashes completes. This sequence can take several minutes to complete.

3. Some or all of the line keys flash green.

   Normally, this sequence takes just a few seconds. However, if the phone flash memory is erased or the phone load is corrupted, the sequence of green flashes will continue while the phone begins a software update procedure. If the phone performs this procedure, the following buttons light to indicate progress:

   • Headset: Phone is waiting for the network and completing CDP and DHCP configuration. A DHCP server must be available in your network.
   • Mute: Phone is downloading images from the TFTP server.
   • Speaker: Phone is writing images to its flash memory.

4. The phone screen displays the Cisco Systems, Inc., logo screen.

5. These messages display as the phone starts:

   • Verifying load (if the phone load does not match the load on the TFTP server). If this message displays, the phone start up again and repeats step 1 through step 4 above.
   • Configuring IP
   • Updating the Trust List
   • Updating Locale
   • Configuring Unified CM List
   • Registering

6. The main phone screen displays:

   • Current date and time
   • Primary directory number
   • Additional directory numbers and speed dial numbers, if configured
   • Softkeys

If the phone successfully passes through these stages, it has started up properly. If the phone does not start up properly, see Startup Problems.

If you are not using DHCP in your network, you must configure these network settings on the Cisco Unified IP Phone after you install the phone on the network:

• IP address

• IP subnet information (subnet mask for IPv4 and subnet prefix length for IPv6)

• Default gateway IP address

• TFTP server IP address

You may also configure these optional settings as necessary:

• Domain name

• DNS server IP address

The security features protect against several threats, including threats to the identity of the phone and to data. These features establish and maintain authenticated communication streams between the phone and the Cisco Unified Communications Manager server, and digitally sign files before they are delivered.

For more information about the security features, see Cisco Unified Communications Manager Security Guide.
