It All Starts With Rack Systems 
Liebert and Knurr brand computer rack systems offer all 
the advanced features and innovative flexibility required to 
accommodate today’s dense and complex IT systems and 
network gear. 
Knurr racks simplify equipment installation, improve cable 
management and increase visibility and control of equipment 
inside the rack.
Liebert enclosures integrate power and cooling to provide 
a complete rack-based support system. Liebert pioneered 
this approach with the Little Glass House and today provides 
enclosures, such as the Liebert MCR and Liebert XDF, which 
protect sensitive electronics in almost any environment.
UPS Systems  
Emerson Network Power offers Liebert brand UPS in all 
three major uninterruptible power supply (UPS) system 
configurations:
Stand-by UPS—Passes utility power straight through to 
the protected load with a 2-6 ms break in power when 
transferring to battery back-up. 
Line-Interactive UPS—Provides power conditioning with 
a 2-6 ms break in power when transferring to battery 
back-up.
On-Line (Double Conversion) UPS—Delivers continuous, 
high-quality AC power to equipment with no break when 
transferring to battery. Protects equipment from virtually 
all power disturbances due to blackouts, brownouts, sags,
