17. Turn on power as described in “Powering the System On” on page 780.
Note: The 4-way processor MCM FRU can have odd-numbered processors or even-numbered
processors. If you have just replaced a 4-way MCM module, notify the customer that they can
determine their processor numbering by issuing the command
lsdev -C on the partition that is using
the new processors. If the customer finds that they have new available processors, and four
processors in the defined state, they can remove the defined processors by using the
rmdev
command, and then use the cfgmgr command.
Methods for Testing MCMs and Pass Through Modules for a Short Circuit
The following testing methods are available for use depending on your testing hardware and system
requirements. Use the following list to determine which of the testing methods you should use:
Method 1 — Multimeter and Original Capacitor Book (part number 11P1540)
Use this testing method if you have a handheld multimeter and the original capacitor book. Use
this method only when Method 2 and Method 3 are unavailable. Refer to “Method 1. Testing
MCMs and Pass Through Modules for a Short Circuit” on page 810.
Method 2 — Multimeter and New Capacitor Book (part number 44P2471)
Use this testing method if you have a handheld multimeter and a new capacitor book, or any
capacitor books with the necessary LGA test-support features. Refer to “Method 2. Testing MCMs
and Pass Through Modules for a Short Circuit” on page 813.
Method 3 — New Capacitor Book (part number 44P2471) and LGA Shorts Tester (LGA-ST) (part
number 44P4107)
This method is required for systems with a 1.5 GHz MCM or higher systems. To perform this
procedure, you must have a new capacitor book (or any capacitor books with the necessary LGA
test-support features), and the new LGA-ST. Refer to “Method 3. Testing MCMs and Pass Through
Modules for a Short Circuit” on page 816.
