Upgrading Ports
Prepare Unit
1 Shut down and park the voicemail system using the Windows Admin program (Setup,
Advanced, Shutdown) or the telephony interface.
2 Disconnect power to the system.
3 Disconnect all phone lines from the voicemail ports.
4 Remove unit from wall by lifting off the mounting screws (if wall mounted).
5 Place unit on sturdy flat surface, preferably on a static dissipating surface such as a
properly grounded anti-static mat.
Access Line Card Mounting and Install Card
1 It is highly recommended to use anti-static precautions, such as a static-dissipating wrist
strap (see Tools Required above), before opening the upgrade kit and whenever the
voicemail unit is open. This point cannot be overstressed. This unit and the hardware
upgrade kit contain static-sensitive components. These components MUST receive
adequate protection from electro-static discharge.
2 Remove top cover by unscrewing the four screws, two on each of the bottom side edges
of the unit. Slide the cover off towards the end with the LED lights.
Figure 6-1. Removing the Cover
3 Locate the line card (the RJ-11 connectors for the phone lines).
4 The old 4 port line card and the new 8 port line card are mounted the same. They differ in
the number of components stuffed onto the line card. During the removal and installation
process, note the location of screws, ribbon cable, and the orientation of the ribbon
cables.
5 Remove the two ribbon cables and note the orientation for installation to the 8 port card.
