15.3.1 Mounting a Single Node
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. To ensure the mounting is secure, use two to four M6 mounting screws for each side of the
shelf assembly. A shelf assembly should be mounted at the bottom of the rack if it is the only unit in the
rack.
