Tripp Lite Hot-Swap Modular UPS systems provide greater availability than other types of UPS systems typically installed in network applications. All UPS types support equipment during a power failure because they feature battery backup support. Line-interactive UPS systems will not support equipment during an internal fault, because they do not feature an internal automatic bypass. Line-interactive and typical on-line UPS systems will not support equipment during UPS repair, because they do not feature an external manual bypass switch and a detachable PDU. Only Tripp Lite Hot-Swap Modular UPS systems provide continuous availability through every application scenario.
