Product Details
6. Connect the SB822 rechargeable external battery unit, using the 2 m (2.2 yd) cable TK821V020. Plug one end into the battery unit and the other into the external battery supply socket of the PM8xx processor unit
7. Ensure that the green Power LED and the yellow Charge LED on the SB822 are both turned on.
8. In a redundant CPU configuration containing two PM858/PM861/PM862/PM864/PM865/PM866/PM867/PM891 processor units, use two SB822 battery units, one for each processor unit.
9. Due to the batteries being connected in parallel, it is necessary, when using the external battery, to remove the internal battery from the PM8xx in order to avoid reducing available memory back-up time.
Do not connect the TK821V020 cable until the AC 800M Controller has been powered up normally and the memory back-up function has been activated, that is, the B(battery) LED flashes. If no normal power supply is connected to the PM8xx processor unit, the CPU memory will immediately start to consume battery power when the cable is connected.
