DLP-G679 Mount the ONS 15454 Shelf in a Rack (Two People)
Tools/Equipment
Prerequisite Procedures
Required/As Needed
Onsite/Remote
Security Level
Note
The ONS 15454 ETSI requires 616.5 mm (24.24 inch) minimum of vertical rack space and 25 mm (1 inch)
below the installed shelf to allow air flow to the fan intake. If a second ONS 15454 ETSI is installed above
a shelf, the air ramp between the shelves provides space for air flow. To ensure that the mounting is secure,
use two to four M6 mounting screws for each side of the shelf. A shelf should be mounted at the bottom of
the rack if it is the only unit in the rack.
Note
The ONS 15454 ANSI must have one inch (25.4 mm) of airspace below the installed shelf to allow air flow
to the fan intake. If a second ONS 15454 is installed underneath a shelf, the air ramp on top of the bottom
shelf provides the desired space. However, if the ONS 15454 is installed above third-party equipment, you
must provide a minimum spacing of one inch (25.4 mm) between the third-party shelf and the bottom of the
ONS 15454. The third-party equipment must not vent heat upward into the ONS 15454.
Procedure
Step 1
Verify that the proper fuse and alarm panel has been installed in the top mounting space. If a fuse and alarm
panel is not present, you must install one according to manufacturer's instructions:
• (ETSI only) Verify that the fuse rating does not exceed 30A.
• The fuse rating for ANSI chassis must not exceed 30A.
Step 2
Ensure that the shelf is set for the desired rack size (either 23 inches [584.2 mm] or 19 inches [482.6 mm]).
Step 3
Using the hex tool that shipped with the assembly, install the two set screws into the holes that will not be
used to mount the shelf. Let the set screws protrude sufficiently to hold the mounting brackets.
