Warnings And Precautions - HP DL740 - ProLiant - 4 GB RAM User Manual

A single ProLiant DL740 server typically weighs between 48 and 61 kg (105 and
135 lbs), depending on configuration. If a single ProLiant DL740 server is the only
component installed in a rack, you must add two ballast kits. Each kit contains two
18 kg (40 lb) ballasts. Two ballast kits (a total of four ballasts) equal 73 kg (160 lb),
bringing the total up to a minimum of 136 kg (300 lb).
If two ProLiant DL740 servers are the only components installed in a rack, you must
add a single ballast kit, which maintains a minimum weight of 91 kg (200 lbs)
remaining in the rack when one of the servers is extended.
For more information, refer to any additional installation documentation provided
with the rack.
