WARNING! There is a risk of explosion, fire, or personal injury if the battery pack is incorrectly replaced or mistreated. To reduce the risk: • Do not attempt to recharge the battery outside of the controller. • Do not expose to water or temperatures higher than 60˚C. • Do not abuse, disassemble, crush, puncture, short external contacts, or dispose of in fire or water. • Replace only with the HP spare designated for this product. CAUTION: Do not dispose of batteries, battery packs, and accumulators with general household waste. Use the public collection system or return them to HP, your authorized HP Partners, or their agents. NOTE: • Always replace batteries in pairs, not individually. • Temperature, age, and cache size can affect battery life. This time span also applies if the controller cache module is removed from the array controller. When power is restored to the storage system, an initialization process writes the preserved data to the hard drives. This is particularly important for data that has been cached by a posted-write operation, but has not yet been written to the hard drives. • Batteries on a new controller might be discharged. In this case, a POST message is displayed on the controller display panel when the controller is powered on, indicating that the controller cache module is temporarily disabled. No user action is required, because internal circuitry automatically recharges the batteries. Recharging the batteries can take up to four hours. The controller functions properly during this time, although without the performance advantage of the controller cache module. When the batteries are charged to 90 percent of their capacity, the controller cache module is automatically enabled. 1. Remove the controller as instructed in Removing the controller. 2. Remove the controller cache module as instructed in Removing the controller cache module. 3. Push down on the battery retaining clip, located near the lower corner of the module. 15516 4. Swing the battery pack away from the cache module to about a 30-degree angle. maintenance and service guide 81
