This is an APC Start-Up Service (5x8 tier), a professional installation and commissioning service rather than a physical product — it's typically sold alongside a UPS or other power-protection hardware purchase from APC/Schneider Electric to have a qualified technician perform the initial site installation, configuration and startup verification of the equipment. The "5x8" designation refers to the service's coverage window, meaning it's delivered during standard business hours across a 5-day work week (as opposed to a 24x7 service tier), so scheduling should account for normal weekday availability rather than expecting after-hours or weekend callout. Services like this are commonly bundled with larger UPS, PDU or data-centre power equipment purchases to ensure correct installation and that manufacturer warranty terms tied to professional commissioning are met, rather than the buyer self-installing complex power infrastructure.
