Adding a node 14-15
Three- to four-node expansion (unshadowed)
Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999
9 Remove and install VP4 or VP8 cards as necessary to meet the
following criteria:
Module 0
Install 24 ports in slots 8 to 11.
Install 24 ports in slots 0 to 3.
Module 1
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.
10 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 completes successfully, 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.
f. After the hexadecimal display on each non-prime nodes
Enhanced MMP40 board reaches .6, the testing has
successfully completed. Power off all modules and proceed
with the software expansion (step 11).
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 from step 10 e.
11 Refer to the “Comprehensive upgrade” chapter in the
System
Installation and Modification Guide
(NTP 555-7001-215) for
further instructions on how to complete the expansion.
12 Configure the switch for the TNs that correspond to the added
ports. See Chapter 12, “Configuring the Meridian 1,” for details.
