14-10 Adding a node

Two- to three-node expansion (unshadowed)

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

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

following criteria:

• Install 24 ports in slots 8 to 11.

• Install a maximum of 24 ports in slots 0 to 3.

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.

4 Remove the address jumper located between slots 4 and 5 of

the backplane. See Chapter 8, “Configuring the backplane and

inspecting the printed circuit packs,” for details. Label this

jumper as Address Jumper and store it. You will need this

jumper if you decide later to install disk shadowing.

5 If you have not yet installed a second network loop, and are

going 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 the module. See Chapter 11, “Installing the

Meridian Mail to PBX interface,” for details.

6 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,” see the same

chapter for troubleshooting procedures.

d. Power off module MM0.

e. If node 1 testing has successfully completed, power up

module MM0 again 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.

f. If the hexadecimal display on each non-prime node’s

Enhanced MMP40 board reaches .6 (this indicates that the

testing has successfully completed), power off the module

and proceed with the software expansion (step 7).

g. If the hexadecimal display on any Enhanced MMP40 board

does not increment to .6, then power off the module, replace

that board, and try again (return to step 6 e).
