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.

NTP-A5 Install the Electrical Interface Assemblies
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband
cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Note EIAs are normally factory installed. Verify that the correct EIA is installed on the shelf assembly. If not,
install the correct EIA.
Step 1 Complete the “DLP-A12 Install a BNC or High-Density BNC EIA” task on page 1-17 as needed. BNCs
are locking connectors; the high-density BNC also allows you to access every port on every card.
Step 2 Complete the “DLP-A13 Install an SMB EIA” task on page 1-19 as needed. SMBs allow you to access
every port on every card using more space and efficient cabling.
Step 3 Complete the “DLP-A14 Install the AMP Champ EIA” task on page 1-21 as needed. AMP Champs are
exclusive to DS-1 cables.
Note To attach cables to the EIAs, see the “NTP-A9 Install the Electrical Card Cables on the
Backplane” procedure on page 1-45.
Step 4 Continue with the “NTP-A6 Install the Power and Ground” procedure on page 1-23.
Stop. You have completed this procedure.
