6- Install the VOIPU Card

! Observe anti-static precautions when handling the VOIPU cards.
·
Wear a suitable anti-static strap connected to an Earth point.
Installation Considerations:
·
Each VOIPU card will use a slot in a 2OPBOX. Each 2OPBOX has two slots.
·
The XN120 can have up to three 2OPBOXs; one box can be connected to each XN120 Unit (1 main
unit plus 2 expansion units).
Are there sufficient trunk ports available for the VOIPU card?
·
The XN120 can have a maximum of 51 trunk ports, including the trunks used by the XN120 unit(s).
·
A VOIPU will use 4 of the XN120's trunk ports.
·
A VOIPU with a VOIPUDB installed will use 8 of the XN120's trunk ports.
·
If there are not sufficient trunks ports available on the system when the VOIPU card is installed the card
will not initialise.

XN120 Voice Over IP Card Guide
Ensure the power is switched OFF to the XN120 system.
Loosen the two screws and remove the lid of the 2OPBOX.
Fit the VOIPU card into any of the slots.
(If you have just one card to install then use Slot CN1 as this will keep
the ports assigned to the card in order should you later install another
card into CN2).
