Once the slide rails are installed on the chassis and on the equipment rack, the
chassis can be installed in the rack by inserting the chassis slide rails into the tracks of
the slide rails already mounted on the equipment rack. When the locking latch on the
chassis slide rail meets the hole in the rack slide rail, the rails lock together. Push the
locking latch in to continue to slide the chassis into the rack rails.
Once the chassis has been fully inserted into the rack, turning the captive
thumbscrews clockwise will lock the chassis securely into the rack.
