Installation into a 19-Inch or 23-Inch Rack
Procedure
To install the chassis in a rack:
1. Determine the preferred placement of the chassis in the rack. The chassis is
24.5 inches high (14U, where 1U is 1.75 inches or 44.45 cm). The center of
the first mounting holes on each side of the chassis is 1.484 inches (3.77 cm)
from the top of the chassis. Mark the appropriate locations for the two upper
mounting screws on each side of the rack.
2. Use the screwdriver to install two screws loosely enough to allow the bracket
keyholes to drop over the screw heads during installation.
3. Place the chassis against the front rails of the rack allowing the installed
mounting screws to pass through the keyholes. Lower the chassis into place,
allowing the keyholes to slide under the screw heads.
This action positions the chassis correctly for installation.
4. Install the remaining three mounting screws for each bracket and tighten all
screws.
Install the next chassis in the same manner.
