High-density equipment creates an environment where traditional air distribution methods are often not effective. Densely packed enclosures can cause IT equipment to overheat, resulting in downtime. The Rack Air Removal Unit SX captures exhaust heat, returns the warm air to the plenum and eliminates hot spots from the data center. Through automatic fan speed control based upon temperature, the fans will self-adjust for optimal performance. With a unit-mounted LCD display, users can view temperatures at the rack, monitor alarm conditions and adjust unit set points. The integrated network management card allows for remote monitoring and control. This space-saving solution mounts to the back of either the NetShelter SX or VX enclosure, requiring zero U space. Zero "U" Solution Mounts to the rear of the rack, leaving valuable rack space for other equipment. LCD display Alpha-Numeric Display which displays system parameters and alarms. Adjustable mounting frame The frame can mount on Netshelter SX or VX enclosures and extends to accommodate 42U, 47U or 48U rack heights. Field replaceable components Fans and electronics module can be readily replaced without uninstalling the unit. Dual A-B Power Inputs Draws power from the UPS for power protection with dual feeds for redundancy. Ducted Exhaust System Removes hot air from the data center to prevent re-circulation and eliminate air mixing. Temperature monitoring Changes in temperature are reported via the user interface or e-mail. Increased capacity Higher rate of heat removal allows more equipment to be installed in each rack. Fan guards A safety measure that provides protection from the fan opening by covering the inlet. Fault-tolerant fan system In the event of a fan failure, the remaining fan(s) will continue to operate.
