for T1/E1 Upgrade Card
Installing the MVP24-48/30-60 Upgrade Card
Both the MVP2410 and the MVP3010 use the same mechanical chassis. This chassis accommodates a second
MultiVOIP circuit card or motherboard module. The add-on module for the MVP2410 is the MVP24-48 product;
the add-on module for the MVP3010 is the MVP30-60 product. The MVP2410G will not accept an expansion
card because its second card slot is occupied by gatekeeper circuitry.
To install an expansion card into an MVP2410 or MVP3010, you must:
1. Power down and unplug the MVP2410/3010 unit.
2. Using a Phillips or star-bit screwdriver, remove the blank plate at the rear of the MVP2410/3010 chassis
(see Figure C-1). Save the screw.

3. A power cable for the expansion card (+5V) is already present within the MVP2410/3010 unit. This power
cable has a two-pin connector. When the rear cover plate has been removed, the cable is accessible from
the rear at the right side of the expansion slot. Locate this connector within the MVP2410/3010. See Figure
C-2.
