DLP-G560 Mounting the Reversible Brackets on the ONS 15454 M6 Shelf for ANSI Rack Configuration
Caution
When mounting the ONS 15454 M6 in a frame with a nonconductive coating (such as paint, lacquer, or
enamel) either use the thread-forming screws provided with the ONS 15454 M6 ship kit, or remove the coating
from the threads to ensure electrical continuity.
Note In an ANSI rack, reversible mounting brackets (19-inch or 23-inch) are used to install the shelf. The mounting
brackets can be installed in the front or the middle position of the chassis.
Procedure
Step 1 To mount the reversible brackets:
• For a 19-inch (482.6-mm) configuration, place the widest side of the mounting bracket flush against the
shelf (see
ANSI Configuration, on page
of the shelf.
• For a 23-inch (584.2-mm) configuration, place the narrow side of the mounting bracket flush against the
shelf (see
ANSI Configuration, on page
of the shelf.
Step 2
Align the mounting bracket screw holes against the shelf screw holes.
Step 3 Insert the screws and tighten them to a torque value of 11.5 in-lb (1.3 N-m).
Step 4
Repeat steps 1 through 3 for the mounting bracket on the opposite side.
The following figure shows mounting the brackets for a 19-inch (482.6-mm) configuration.
