Hardware settings
Do the following procedure as you install fax boards.
WARNING! Do not remove the cover from the server or expansion
chassis while the power is on, if a CPD/220 fax board is already
installed. The voltage level from the board can cause injury.
WARNING! Never connect a loop-start phone line to a DID fax
port. The voltage in the loop-start line will damage the fax board. If
you are unsure whether the line is a loop-start line, test it with a
volt meter to confirm that there is no voltage.
To set switch block SW1
The switch block SW1 settings determine the fax ports' I/O
addresses.
The CPD/220 board contains four fax ports. Depending on the
configuration of the Unity server, you can install up to two
CPD/220 boards.
Set the SW1 switches on each board as shown below.
First board
Ports 0–3
Second board
Ports 4–7
