IBM feature #1051 is the battery assembly for the IBM System Storage DS8870, machine types 2421, 2422, 2423 and 2424, models 961 and 96E. It is the single-phase DC-UPS battery service module, applies to all models, and is a lead acid battery set.
Every DS8870 rack contains two DC-UPS units with integrated batteries, and each DC-UPS takes one or two battery service module sets depending on the configuration ordered. A model 961 or 96E without the extended power line disturbance option (#1055) takes one #1051 set per DC-UPS, and a model with #1055 takes two. The on-battery period is 4 seconds without #1055 and 50 seconds with it. If both DC-UPS units in a frame lose AC input, the units go on battery and the system starts a shutdown when AC is not restored.
Battery service module sets sit at UPS locations E1-E12 and E2-E12 in every system, with further sets at E1-E11 and E2-E11 and, in larger configurations, E1-E10 and E2-E10. Each set connects through a primary module with J20 power and J30 signal connectors and secondary modules with J21 power and J31 signal connectors. A separate feature code is not required for the DC-UPS itself.
