Checking the date of last charge for the rack batteries

For racks that have the battery modules present, each module has two dates on the battery label. The label has the "Born on Date" and "Last Charge Date." Complete the following steps to verify the date of last charge for the batteries.

1. At the front, lower left of each rack being installed, observe the rack battery modules (if present). Are there any modules with a "Last Charge Date" more than 8 months prior to today's date?
   • Yes, go to the next step.
   • No, go to Checking for weight reduction feature.
2. Is this rack new from IBM® manufacturing?
   Note: New racks from manufacturing will have a flyer that is similar to one of the following taped to the rack operator panel under the front cover. See the following examples:

   This product manufactured for: IBM Data Storage Systems Ltd. Deakvari fasor 16-18 H-2600 Vac Hungary Machine S/N xxxxx Ucode bundle installed on this machine is: xxxxxxx PN 17P8868

   Assembled in the U.S.A. of U.S. and non-U.S. components. By IBM Corporation, San Jose, California Machine S/N xxxxx Ucode bundle installed on this machine is: xxxxxxx PN 17P8927

   • Yes, go to step 5.
   • No, go to the next step.
3. At the site where this rack was previously installed, the service representative should have performed discontinue procedures for this rack. The procedure directs the service representative to write on a piece of paper the date that the rack was discontinued. The dated paper is then stored in the front upper left document enclosure of the rack. The discontinue date is the new "Last Charge Date". Can you locate the paper with the discontinue date of the rack?
   • Yes, go to the next step.
   • No. It is not possible for you to determine if the battery modules have not been charged for more than 8 months. You will continue with the installation procedure which will automatically determine if the battery modules can be charged. If they can be charged the installation will proceed as normal. If they cannot be charged, an error is displayed and you will be guided to replace the battery modules. Go to Checking for weight reduction feature.
4. Are there any modules with a "Last Charge Date" more than 8 months prior to today's date?
   • Yes, go to the next step.
   • No, go to Checking for weight reduction feature.
5. The batteries have not been charged for more than 8 months. They are now discharged and cannot be charged by the rack charging system. You must replace all battery module sets in this rack before you continue with the installation.
   1. Replace the battery modules now with the rack powered off. You can use the procedures in the service information center, see Exchange the battery module set.
