Have one person hold the shelf assembly in place while the other person uses the Phillips screwdriver to
install one mounting screw in each side of the assembly.
Step 7
When the shelf assembly is secured to the rack, install the remaining mounting screws.
Note
Use at least one set of the horizontal screw slots on the shelf assembly to prevent slippage.

Step 9
Return to your originating procedure (NTP).
DLP-G7 Mount Multiple Shelf Assemblies in a Rack
Note
A standard ETSI rack can hold three ONS 15454 ETSI shelf assemblies and two air ramps. When
mounting a shelf assembly in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the
stabilizers before mounting or servicing the unit in the rack.
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 assembly to allow air flow to the fan intake. If a second
ONS 15454 ETSI is installed above a shelf assembly, the air ramp between the shelves provides space
for air flow. When using third-party equipment above the ONS 15454 ETSI, provide a minimum of
25 mm (1 inch) between the third-party unit and the bottom of the ONS 15454 ETSI. The third-party
equipment must not vent heat upward into the ONS 15454 ETSI.
Purpose
This task installs multiple shelves in a rack.
