• Ethernet Category 5e or Ethernet Category 6 cabling.
• Either the 802.3at PoE or the 802.3af PoE injector specification.
Administration methods
You can use the following methods to administer the devices. The following table lists the groups
of configuration parameters that you can administer through each of the corresponding methods:

Precedence of the methods
You can configure most of the parameters using multiple configuration sources. If you configure a
parameter through more than one method, the device applies the settings of the method that has
a higher precedence. The following list shows the precedence of the methods in the order from
highest to lowest:
1. Administration menu on the phone.
2. Web UI. The web interface of the phone has the same precedence than the Administration
menu.
3. Settings file.
4. DHCP.
5. LLDP. When configured using LLDP, network Layer 2 related parameters such as
L2QVLAN, L2Q, L2QAUD, L2QSIG, DSCPAUD, DSCPSIG, and PHY2VLAN have higher
precedence over other sources if the same settings are provided through other
administrative methods.
Note:
When parameters of the settings file are removed, or are not used, they are reset to the
default value.
