4 If you plan to have more than 24 ports, install a second network

loop cable from the Meridian 1 switch to the J5 connector on

the backplane of module MM0. See Chapter 11, “Installing the

Meridian Mail to PBX interface,” for details.

5 To have more than 48 ports do the following:

a. Install a utility card in module MM1, slot 5.

b. Install a third network loop cable from the Meridian 1 switch

to the J4 connector on the backplane of module MM1. See

Chapter 11, “Installing the Meridian Mail to PBX interface,”

for details.

c. Remove the EVB terminator, if there is one, from shroud S7

in module MM1.

6 Remove and install VP4 or VP8 cards as necessary to meet the

following criteria:

Module 0

• Install 24 ports in slots 8 to 11.

Module 1

• Install 24 ports in slots 0 to 3.

• Install a maximum of 24 ports in slots 8 to 11.

Note:

Fill up the voice card slots: start from the left in a given

node and begin with any VP8 cards designated for that node.

7 Perform diagnostics as follows:

a. Check that the main administration terminal is connected to

node 1.

b. Power up module MM0 and observe the node 1 bootup

messages on the terminal and the hexadecimal display on

node 1’s Enhanced MMP40 board.

c. If the terminal output or the hexadecimal display does not

follow the normal bootup sequence described in Chapter 17,

“Troubleshooting operational problems,” then go to Chapter

17 for troubleshooting procedures.

d. Power off module MM0.

e. If node 1 testing successfully completes, power up both

modules and observe the hexadecimal display on the

Enhanced MMP40 boards in the remaining nodes.

The hexadecimal displays should increment to at least .6 on

each non-prime node.
