To install the Mailbox Expansion Card, insert the card in the vertical
slot on the lower front of the voice messaging system module
(see Figure 2-3). Make sure the arrows on the Mailbox Expansion Card
label face up and in. Also make sure the card is pushed in all the way.
Turn on power to the control unit. The green Power LED should light—if it
does, skip to Step 6. If the green Power LED does not light, power down
the control unit, reseat the voice messaging system module, then power
up the control unit again. If the green Power LED still does not light, call
for support as indicated on the inside front cover of this guide.
Next, the voice messaging system module performs self-diagnostic tests.
The LEDs work as follows:
