8 Getting Started
Installing the Trunk/Extension Cards
1. Before installing the optional service cards, cut and remove the appropriate dummy cover
plates from the main unit.
CAUTION
For safety reasons, smooth the cut edges after removing the dummy cover plates.
2. Position the card in the open slot, making sure that the tabs on the both sides of the card
fit into place. Then, holding the card firmly in place, lower the rear end so that the hole of
the card fits over the extension bolt.
CAUTION
When installing the optional service cards, do not put pressure on any parts of the main
board. Doing so may result in damage to the Hybrid IP-PBX.
