This APC Smart-UPS is a line-interactive unit rated at 3000VA/2100W, built into a 2U rack chassis with the mount kit included — so it goes straight into a standard 19" rack without separate hardware. A VRLA battery is included in the unit as sold, giving it a self-contained runtime out of the box, and the listing explicitly notes no network management card is fitted, meaning remote/SNMP monitoring would need an optional card added separately if that's required. It carries a 2-year repair-or-replace warranty. Line-interactive (rather than online/double-conversion) means it corrects minor voltage sags and surges without switching to battery, only fully transferring to battery on an actual outage — a reasonable middle ground between cost and protection for rack equipment that doesn't need zero-transition-time online power.
