Chapter 1 Install the Shelf and Common Control Cards
NTP- G5 Mount the Shelf Assembly in a Rack (One Person)
DLP-G5 Mount the Shelf Assembly in a Rack (One Person)
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. To ensure that 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.
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:
•
The fuse rating for both ETSI and ANSI chassis must not exceed 30A.
Step 2
Ensure that the shelf assembly is set for the desired rack size (either 23 inches [584.2 mm] or 19 inches
[482.6 mm]).
Purpose
This task allows one person to mount the shelf assembly in a rack.
