## Manually Setting the DHCP Client Hardware Address

Use this procedure to manually set or change the Client Hardware Address, if you use static addressing rather than DHCP.

1. While the telephone is on-hook and idle, press the following sequence of keys on the telephone’s faceplate:

Mute 2 4 2 3 3 7 # (Mute C H A D D R #)

NOTE: Press the Mute button momentarily. Do not press this button while pressing other keys/buttons.

The telephone displays the following text left-justified at the top of the display:

chaddr=ddd New=

where ddd is the value of NVCHADDR, the system variable for the DHCP Client Hardware Address.

1. To change the Client Hardware Address value, enter a valid client hardware address. This value is usually the MAC address, which DHCP then converts to an integer preceded by zeroes.

For all IP telephones, if a value different from the current value of NVCHADDR is entered, the following text displays left-justified at the top of the display:

Save new value? *=no #=yes

1. Press the * button to terminate the procedure, or the # button to save the new value. If you press the # button, the telephone displays the following text:

New value being saved

The telephone saves the new value.
