Installing battery module sets

Perform this task on any rack from which the battery module sets have been removed.

1. Locate the weight reduction status chart:
   • If the rack is new and IBM® manufacturing applied FC 0200, the status sheet will be computer generated. Continue to the next step.
   • If the rack is not new from IBM manufacturing and FC 0200 was applied by a field service representative, the status sheet will be hand printed. Go to step 3.
2. Remove the Weight Reduction Status chart from the CE envelope. Additional copies are in the boxes on the pallet. The Weight Reduction Status chart contains a record of the original installed location of each battery module. For a sample chart, see Figure 1. For a description of the columns in the chart, see Table 1. Then go to step 4.
   Note: If the status chart cannot be found, contact the next level of support. There is a procedure to get a PDF copy sent from San Jose manufacturing.

   Table 1. Description of columns in a sample Weight Reduction Status chart

   Column in chart	Description of column
   CRINSQ	Battery module serial number
   CRMMDL	Rack model number (mmm in the location code for the battery module chassis: U2nnn.mmm.sssssss-E1x-E2)
   MCSN	Machine serial number
   CRPLL2	Location of the battery module chassis (xxx in the location code for the battery module chassis: U2nnn.mmm.sssssss-xxx-E2; see Figure 2)
   (margin to the right of the table)	Location of the battery module, handwritten by manufacturing (when the rack is viewed from the front, B1 is on the left; see Figure 2)

3. Locate the Weight Reduction Status chart, it should be included in one of the boxes for the removed parts. The Weight Reduction Status chart contains a record of the original installed location of each battery module.
4. Use the information in the status chart to determine where each battery module must be installed, and then go to step 5.

5. Using the location information from step 2, slide each battery module into its original location and secure it with the thumbscrew. For additional guidance, go to Exchange the battery module set
6. Continue with Installing storage enclosures.
