Adding a node 14-33
Four- to five-node expansion (shadowed)
Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999
12 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 all the
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
successfully completes. Power off all modules and proceed
with the software expansion (step 13).
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 12 e).
13 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.
