Warning

To prevent the equipment from overheating, do not operate it in an area that exceeds the maximum

recommended ambient temperature of 131°F (55°C). To prevent airflow restriction, allow at least

1 inch (25.4 mm) of clearance around the ventilation openings.

Warning

The ONS 15454 should be installed in the lower rack position or mounted above another ONS 15454

shelf assembly.

Warning

The ONS 15454 must have 1 inch of airspace below the installed shelf assembly to allow air flow to

the fan intake. The air ramp (the angled piece of sheet metal on top of the shelf assembly) provides

this spacing and should not be modified in any way.

Note The 10 Gbps compatible shelf assembly (15454-SA-10G) and fan-tray assembly (15454-FTA3) are

required with the ONS 15454 XC10G, OC-192, and OC-48 any slot (AS) cards.

Step 1 Complete the “DLP-A3 Reverse the Mounting Bracket to Fit a 19-inch (482.6 mm) Rack” task on

page 1-6 if you need to convert from a 23-inch (584.2 mm) to a 19-inch (482.6 mm) rack.

Step 2 To install the air filter in an alternative location, complete the “DLP-A4 Install the External Brackets and

Air Filter” task on page 1-8.

Step 3 Complete the necessary rack mount task:

•DLP-A5 Mount the Shelf Assembly in a Rack (One Person), page 1-9

•DLP-A6 Mount the Shelf Assembly in a Rack (Two People), page 1-10

•DLP-A7 Mount Multiple Shelf Assemblies in a Rack, page 1-11

Step 4 Continue with the “NTP-A3 Open and Remove the Front Door” procedure on page 1-12.

Stop. You have completed this procedure.

DLP-A3 Reverse the Mounting Bracket to Fit a 19-inch (482.6 mm) Rack

Caution Use only the fastening hardware provided with the ONS 15454 to prevent loosening, deterioration, and

electromechanical corrosion of the hardware and joined material.

Caution When mounting the ONS 15454 in a frame with a nonconductive coating (such as paint, lacquer, or

enamel) either use the thread-forming screws provided with the ONS 15454 shipping kit, or remove the

coating from the threads to ensure electrical continuity.

Step 1 Remove the screws that attach the mounting bracket to the side of the shelf assembly.

Step 2 Flip the detached mounting bracket upside down.

Text imprinted on the mounting bracket will now also be upside down.

Step 3 Place the widest side of the mounting bracket flush against the shelf assembly (see Figure 1-1).

The narrow side of the mounting bracket should be towards the front of the shelf assembly. Text

imprinted on the mounting bracket should be visible and upside down.

Step 4 Align the mounting bracket screw holes against the shelf assembly screw holes.

Step 5 Insert the screws that were removed in Step 1 and tighten them.

Step 6 Repeat the task for the mounting bracket on the opposite side.

Chapter 1 Install the Shelf and Backplane Cable

NTP-A2 Install the Shelf Assembly

DLP-A4 Install the External Brackets and Air Filter

Note The shelf assembly ships with external (bottom) brackets that you can use to install the air filter on the

bottom of the shelf rather than beneath the fan-tray assembly. When you use the brackets to install the

fan-tray air filter, you do not need to remove the fan-tray assembly to access the air filter. Attach the

brackets to the bottom of the shelf assembly before installing the rack.

Note If you choose not to install the brackets, install the air filter by sliding it into the compartment at the

bottom of the shelf assembly. Each time you remove and reinstall the air filter in the future, you must

first remove the fan-tray assembly. Do not install an air filter in both filter locations on any shelf

assembly.

Step 1 With the fan-tray assembly removed, place the ONS 15454 face down on a flat surface.

Note Although the filter will work if it is installed with either side facing up, Cisco recommends that you

install it with the metal bracing facing up to preserve the surface of the filter.

Step 2 Locate the three screw holes that run along the left and right sides of the bottom of the shelf assembly.

Step 3 Secure each bracket to the bottom of the shelf assembly using the screws (48-0003) provided in the

backplane standoff kit (53-0795-XX).

Each bracket has a filter stopper and a flange on one end. Make sure to attach the brackets with the

stoppers and flanges facing the rear of the shelf assembly (the top, if the ONS 15454 is face-down during

installation).

Figure 1-2 illustrates bottom bracket installation. If you do not use the brackets, in the future you must

remove the fan-tray assembly before removing the air filter. The brackets enable you to clean and replace

the air filter without removing the fan-tray assembly.

Purpose This task installs the external brackets and air filter.

Step 5 Return to your originating procedure (NTP).

DLP-A5 Mount the Shelf Assembly in a Rack (One Person)

Step 1 Verify that the proper fuse and alarm panel has been installed in the top mounting space. If a fuse and

alarm panel has not been installed, you must install one according to manufacturer’s instructions.

•If installing the 15454-SA-ANSI shelf assembly, a 100-A fuse panel (30-A fuse per shelf minimum)

is required.

•If installing the 15454-SA-NEBS3 shelf assembly, a standard 80-A fuse panel (20-A fuse per shelf

minimum) is required.

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.

Step 3 Using the hex key that shipped with the assembly, install the two set screws into the screw holes that will

not be used to mount the shelf.

Step 4 Lift the shelf assembly to the desired rack position and set it on the set screws.

Step 5 Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 6 Using the Phillips screwdriver, install one mounting screw in each side of the assembly.

Step 7 When the shelf assembly is secured to the rack, install the remaining mounting screws.

Note Use at least one set of the horizontal screw slots on the ONS 15454 to prevent slippage.

Step 8 Remove the temporary set screws.

Step 9 Return to your originating procedure (NTP).

DLP-A6 Mount the Shelf Assembly in a Rack (Two People)

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’s instructions.

•If installing the 15454-SA-ANSI shelf assembly, a 100-A fuse panel (30-A fuse per shelf minimum)

is required.

•If installing the 15454-SA-NEBS3 shelf assembly, a standard 80-A fuse panel (20-A fuse per shelf

minimum) is required.

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]).

Step 3 Using the hex key that shipped with the shelf assembly, install the two set screws (48-1003-XX) into the

screw holes that will not be used to mount the shelf.

Step 4 Lift the shelf assembly to the desired position in the rack.

Step 5 Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 6 While one person holds the shelf assembly in place, the other person can install one mounting screw in

each side of the assembly using the Phillips screwdriver.

Purpose This task allows two people to mount the shelf assembly in a rack.
