MVP428 Upgrade Card Installation Instructions_______________________
11. Locate the male 60-pin vertical connector near the LED edge of the main
circuit card. Check that pins are straight and evenly spaced. If not, then
correct for straightness and spacing. Locate the 60-pin female connector
on the upgrade circuit card.
12. Set the upgrade circuit card on top of the main circuit card. Align the
upgrade card’s 4 pairs of phone-jacks with the 4 pairs of holes in the
backplane of the main card. Slide the phone jacks into the holes.
13. Mate the upgrade card’s 60-pin female connector with the main card’s 60-
pin male connector.

14. There are four copper-plated attachment holes, two each at the front and
rear edges of the upgrade card. Attach the upgrade card to the main card
using 4 Phillips screws. The upgrade card should now be firmly attached
to the main card.
15. Slide the main circuit card back into the chassis far enough to allow re-
connection of power cable.
16. Re-connect power cable.
17. Slide the main circuit card fully into the chassis.
18. Re-attach the backplane of the main circuit card to the chassis with 3
screws.

Installation Instructions
for
MVP428 Upgrade Card
Note:Your MultiVOIP firmware must be at version 6.09 or higher
before you can install the MVP428 Upgrade Card.
In this procedure, you will install an additional circuit board into the MVP410,
converting it from a 4-channel voip to an 8-channel voip.
Procedure in Detail
1. Power down and unplug the MVP410 unit.
2. Using a Phillips driver, remove the blank cover plate at the rear of
the MVP410 chassis. Save the screws.

5. Unplug the power connector from the main circuit board.
6. Slide the main circuit board completely out of the chassis and place on a
non-conductive, static-safe table-top surface.
7. Remove mounting hardware (2 screws, 2 nuts, and 4 standoffs) from its
package.
8. On the phone-jack side of the circuit card, three screws attach the circuit
card to the back panel. Two of these screws are adjacent to the four phone-
jack pairs. Remove these two screws.

10. There are two copper-plated holes at the LED edge of the circuit card.
Place a nut beneath each hole (lockwasher side should be in contact with
board) and attach a standoff to each location.
