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.
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 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]).
The following figure shows the rack-mounting position for the ONS 15454 ETSI.
