If you do not properly install and securely fasten the rack rails according to this procedure, you risk
serious personal injury and could damage the storage enclosure.
Attach the outer rack rails in 4U increments. Select the location for the outer rails based on the following factors:
•
Rack system safety precautions
•
Position in the rack
•
Population of the storage enclosure, full or partial
