What the shared parts are
- Floor PDUs, RPPs, static transfer switches, ATS — Floor-mounted power distribution units, remote power panels, and the static and automatic transfer switches that route power between utility, UPS, and generator sources down to the rack level.
- UPS (static, modular, rotary/DRUPS) & UPS power semis — Uninterruptible power supplies that bridge the gap between a utility outage and generator start, built as static (battery-based), modular, or rotary/diesel-rotary (DRUPS) designs, plus the power semiconductors inside them.
- Paralleling switchgear & generator controls — Switchgear and control systems that synchronize and combine the output of multiple generators so they can operate as one larger backed-up power source, and manage the transition between utility, UPS, and generator power.
