This chapter helps you install the Cisco Unified IP Phone on an
IP telephony network.
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 Phone and telephony networks.
For the Cisco Unified IP Phone to successfully operate as a
Cisco Unified IP Phone endpoint in your network, your network must meet the
VoIP configured on your Cisco routers and gateways
Cisco Unified Communications Manager installed in your network
and configured to handle call processing
IP network that supports DHCP or manual assignment of IP address,
gateway, and subnet mask
The Cisco Unified IP Phone displays the date and time from Cisco
Unified Communications Manager. The time displayed on the phone can differ from the Cisco Unified Communications Manager time by up to 10 seconds. If the Cisco Unified Communications Manager
server is located in a different time zone than the phones, the phones do not
display the correct local time.
Cisco Unified Communications Manager Setup
The Cisco Unified IP Phone requires
Cisco Unified Communications Manager to handle call processing. See
Cisco Unified Communications Manager Administration Guide or
refer to the context-sensitive help in the Cisco Unified Communications Manager
application to ensure that Cisco Unified Communications Manager is set up
properly to manage the phone and to properly route and process calls.
If you plan to use autoregistration, verify that it is enabled
and properly configured in Cisco Unified Communications Manager before
connecting any Cisco Unified IP Phone to the network. For information about
enabling and configuring autoregistration, see
Cisco Unified Communications Manager Administration Guide.
You must use Cisco Unified Communications Manager
Administration to configure and assign telephony features to the Cisco Unified
In Cisco Unified Communications Manager Administration, you can
add users to the database, add users to user groups, and associate users to
specific phones. In this way, users gain access to their Cisco Unified CM User
Option page to configure items such as call forwarding, speed dialing, and
voice messaging system options.
The back of the Cisco Unified IP Phone 6901 includes a network
port, which the phone uses to connect to the network.
The back of the Cisco Unified IP Phone 6911 includes these
Network port: Labeled Network
Access port: Labeled Computer (also known as the PC port)
Cisco Unified IP Phone 6911 has a PC port. The
Cisco Unified IP Phone 6901 does not have a PC port.
The network port supports 10/100 megabits per second (Mb/s)
half- or full-duplex connections to external devices. You can use either
Category 3, 5, or 5e cabling for 10 Mbps connections, but you must use Category 5 or 5e
for 100 Mb/s connections.
You can mount the Cisco Unified IP Phone 6901 on the wall
using a standard telephone wall plate with an opening for an RJ-45 connector.
Cisco recommends that you use Leviton Wall Mount plate (Leviton type number:
4108W-0SP) to wall mount the Cisco Unified IP Phone 6901.
You can mount the Cisco Unified IP Phone 6911 on the wall
using special brackets available in the Cisco Unified IP Phone wall mount kit.
The phone does not include wall mount kits. Wall mount kits must be ordered separately.
The message waiting (MWI) LED on the handset and the Mute button LED light during boot up. After successful completion of the boot up process, the LEDs turn off, and the phone is ready for calls. If the phone successfully boots up, it has started up properly. If the phone does not start up properly, the user receives a reorder tone.
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 the
related topics and the
Cisco Unified Communications Manager Security Guide.
