Figure 9: ONS 15454 ETSI Shelf Dimensions
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 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 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.
The following figure shows the rack mounting position for the ONS 15454 ETSI shelf.
