2.2 Installation of the PBX
Note
When installing or removing the optional service cards, the power switch of the PBX must be in the off
position.
Installing Optional Service 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.
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.
