Provides sine wave output, complete battery backup and power protection for mission-critical IT installations, edge networks and other advanced network applications. This 9PX rack-mount online double-conversion UPS system provides reliable, low-maintenance battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage valuable IT equipment or destroy data. Ideal for locations that are difficult to access or infrequently maintained, the 9PX2000RT-L is an efficient "set it and forget it" solution. It's ideal power management for education, commercial, financial or healthcare networking components, including Cisco switches and servers. The hot-swappable maintenance-free lithium-ion battery modules have a service life of 8 to 10 years. They allow you to work through short power failures and give you enough time to safely save files and shut down your system in case of a prolonged blackout. Exclusive ABM technology increases battery life by 50% and closely monitors battery health to provide advanced notice when batteries need replacing. These lithium iron phosphate (LFP) batteries provide 80 to 120 percent more runtime at full load than equivalent lead-acid UPS systems while weighing up to 40% less, reducing the overall UPS weight. For mission-critical applications demanding continuous uptime, the UPS supports the connection of up to 4 expanded battery modules (9PXEBM72RT-L, sold separately) for hours of extended runtime. The NETWORK-M2 network card (sold separately or as a network card bundle) enables full remote configuration and management, including load shedding, reboots of connected equipment and safe shutdowns. UPS Firmware can also be flashed remotely through the NETWORK-M2 without dropping the load, so you don't have to plan for downtime. The card meets both UL 2900-1 and IEC 62443-4-2 standards for cybersecurity, which were developed to address the vulnerability of connected devices to known malware / exploits and to protect business from these risks. The optional Environmental Monitoring Probe Gen 2 (EMPDT1H1C2, sold separately) provides a variety of environmental monitoring capabilities, including temperature and humidity conditions. One L5-20R and six 5-20R managed outlets provide connected equipment with pure sine wave AC output and allow you to monitor power consumption down to the outlet group level. Power provided by these outlets is filtered to protect connected equipment against damaging surges and line noise. Four 5-20R outlets are grouped into two load banks that let you shed non-critical loads to extend runtime for critical loads. The high-contrast front-panel LCD provides control settings and critical information to help diagnose any issues. The interface rotates to accommodate both rack-mount and tower configurations, and it tilts up to 45° for more comfortable viewing. RS-232 And USB ports connect to a serial-enabled device for a variety of communication options (cables are included). A dry-contact relay port can be programmed through the LCD to provide reliable communications to automation and industrial components. The RPO/ROO port permits emergency shutdown or remote restart of all connected equipment.
