Set Up Your Device Network - Polycom CX5500 Administrator's Manual

Set Up Your Device Network

The Polycom CX5500 system operates on an Ethernet local area network (LAN). This section shows you
several automated and manual ways to configure Polycom phones to operate in a LAN.
Connecting your Polycom phone to the LAN will initiate a startup sequence. Note that only step 1 is
required and automatic (except for phones on a WLAN). Steps 2, 3, and 4 are optional as all these
settings can be manually configured on the device. It is common to complete step 3 using a DHCP server
within the LAN. The phone uses the following startup sequence:
1 The phone establishes network connectivity.
Wired phones will establish a 10M/100M/1000M network link with an Ethernet switch device.
Telephony will not function until this link is established. If the phone cannot establish a link to the
LAN, an error message Network link is Down will display.
2 Apply appropriate security and Quality of Service (QoS) settings (optional).
Assign the phone to a VLAN and/or 802.1X authentication.
3 Establish DHCP negotiation with the network and IP address, network addressing options, network
gateway address, and time server.
4 Provision server discovery.
To facilitate boot time, contacting the provisioning server is delayed until the phone is operational.
You can also disable contacting the provisioning server, for example, to reduce the server load
after a power failure.
After the provisioning server discovery is complete, the phone initiates the provisioning process described
