Tripp Lite's slim SmartPro 2U 3000 UPS System provides intelligent, line-interactive battery backup with extended-run capability for networks and servers. It may be mounted in racks (using only 2U rackspace), as a tower, on walls or under counters. 3, 000 VA of battery backup allows you to work through short blackouts or safely shut down during longer ones. The unit has 9 outlets, diagnostic LEDs and 4 built-in communications ports that work with PowerAlert Software to provide e-mail or pager notification of power problems and the simultaneous automatic unattended shutdown of multiple servers.
