Procedure
1. Position one of the two adjustable bottom-support rails at the lowest possible RU in the rack or cabinet
and adjust the length of the rail so that it stretches from the outer edges of the front and rear vertical
mounting rails. Be sure there is at least 9 RU of vertical space above the rails to install the chassis.
You can expand the rail so that its mounting brackets are spaced between 24 to 32 inches (61.0 to
81.3 cm).
