Mounting an ONS 15327 in a rack
One person can install the shelf assembly using the mounting screws provided. For easier lifting, the
shelf should be empty of cards and the fan tray.
Procedure: Mount the ONS 15327 in a Rack
Step 1
Ensure that the shelf assembly is set for the desired rack size (either 19 or 23 inches).
Step 2
Lift the shelf assembly to the desired rack position.
Step 3
Align the screw holes on the mounting ears with the mounting holes in the rack.
Step 4
Install one mounting screw in each side of the assembly.
You should use at least one set of the horizontal screw slots on the mounting brackets to prevent future
slippage.
Step 5
When the shelf assembly is secured to the rack, install the remaining mounting screws.
1.3.3 Mounting Multiple Nodes
Most standard seven-foot racks can hold 12 ONS 15327s and a fuse and alarm panel.
