2.3 Installing the Optional Service Cards
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.
