Observe the "Last Charge" label on each primary battery service module (top module in the vertical set of four). See Figure 2.
Note: The label may be located on the front surface of the BSM or on the top surface of the BSM power connector. For this step, you will use the "Last Charge" date , not the "Born On" date .

Do any primary modules have a "Last Charge" date more than 8 months prior to today's date?
- Yes, go to the next step.
- No, reinstall the BSM set enclosure covers (if removed) and then go to step 7.

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 the topic Checking for weight reduction, feature code 0200.
Are there any modules with a "Last Charge Date" more than 8 months before today's date?
- Yes, go to the next step.
- No, if removed, reinstall the covers and then go to Checking for weight reduction, feature code 0200.
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. Open the service information center. If you have a management console available in a Model 961 that is already powered on, you can display the procedure there. If not, use the service documentation CD included in the ship group to view the information center. Go to Exchanging parts > Rack Power and Cooling > Models 961, 96E > DC-UPS battery service module (BSM) set.
