DLP-4 Install the External Brackets and Air Filter
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. The brackets consist of two grooved metal pieces that attach to the bottom of the shelf assembly using three screws each. 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.
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.

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.
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.
Figure 1-2 Installing the external brackets
Step 4 Slide the air filter into the shelf assembly.
Step 5 Return to your originating procedure (NTP).
DLP-5 Mount the Shelf Assembly in a Rack (One Person)

DLP-7 Mount Multiple Shelf Assemblies in a Rack
Note The ONS 15454 must have one inch of airspace below the installed shelf assembly to allow air flow to the fan intake. If a second ONS 15454 is installed underneath a shelf assembly, the air ramp on top of the bottom shelf assembly provides the desired space. However, if the ONS 15454 is installed above third-party equipment, you must provide a minimum spacing of one inch between the third-party shelf assembly and the bottom of the ONS 15454. The third-party equipment must not vent heat upward into the ONS 15454.
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-amp fuse panel (30-amp fuse per shelf minimum) is required.
•If installing the 15454-SA-NEBS3 shelf assembly, a standard 80-amp fuse panel (20-amp fuse per shelf minimum) is required.

Step 1 Verify that the office ground cable (#6 AWG stranded) is connected to the top of the bay according to local site practice.
Step 2 Attach one end of the shelf ground cable (#6 AWG) to the right side of the backplane ground nut. See Figure 1-8 for the location of the ground on the backplane.
Note When terminating a frame ground, use the kep-nut provided with the ONS 15454 and tighten it to a torque specification of 31 in-lbs. The kep-nut provides a frame ground connection that minimizes the possibility of loosening caused by rotation during installation and maintenance activity. The type of prevention the kep-nut provides for the frame ground connection is inherently provided by the terminal block for battery and battery return connections.
Figure 1-8 Ground location on the backplane
Step 3 Attach the other end of the shelf ground cable to the bay.
Step 4 Return to your originating procedure (NTP).
DLP-17 Connect Office Power to the ONS 15454 Shelf
Note If the system loses power or both TCC+ cards are reset and the system is not provisioned to get the time from an NTP/SNTP server, you must reset the ONS 15454 clock. After powering down, the date defaults to January 1, 1970, 00:04:15. To reset the clock, see the "NTP-25 Set Up Name, Date, Time, and Contact Information" procedure.
Note If you encounter problems with the power supply, refer to the Cisco ONS 15454 Troubleshooting Guide.
Warning Do not apply power to the ONS 15454 until you complete all installation steps and check the continuity of the -48 VDC and return.
Step 1 Connect the office power according to the fuse panel engineering specifications.
Step 2 Measure and cut the cables as needed to reach the ONS 15454 from the fuse panel. Figure 1-9 shows the ONS 15454 power terminals.
Step 3 Dress the power according to local site practice.
Warning When installing the ONS 15454, the ground connection must always be made first and disconnected last.
Figure 1-9 ONS 15454 power terminals
Step 4 Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables connected to the BAT1/RET1 (A) power terminals as 1, and the cables connected to the BAT2/RET2 (B) power terminals as 2.
Note Use only pressure terminal connectors, such as ring and fork types, when terminating the battery, battery return, and frame ground conductors.
Caution Before you make any crimp connections, coat all bare conductors (battery, battery return, and frame ground) with an appropriate antioxidant compound. Bring all unplated connectors, braided strap, and bus bars to a bright finish, then coat with an antioxidant before you connect them. You do not need to prepare tinned, solder-plated, or silver-plated connectors and other plated connection surfaces, but always keep them clean and free of contaminants.
Caution When terminating power, return, and frame ground, do not use soldering lug, screwless (push-in) connectors, quick-connect, or other friction-fit connectors.
Step 5 Strip 1/2 inch of insulation from all power cables that you will use.
Step 6 Crimp the lugs onto the ends of all power leads.
Note When terminating battery and battery return connections as shown in Figure 1-9, follow a torque specification of 10 in-lbs.
Step 7 Terminate the return 1 lead to the RET1 backplane terminal. Use oxidation-prevention grease to keep connections non-corrosive.
Warning Do not secure multiple connectors with the same bolt assembly.
Step 8 Terminate the negative 1 lead to the negative BAT1 backplane power terminal. Use oxidation prevention grease to keep connections non-corrosive.
Step 9 If you use redundant power leads, terminate the return 2 lead to the positive RET2 terminal on the ONS 15454. Terminate the negative 2 lead to the negative BAT2 terminal on the ONS 15454. Use oxidation-preventative grease to keep connections non-corrosive.
Step 10 Route the cables out below the power terminals using the plastic cable clamp, as shown in Figure 1-9.
Step 11 Return to your originating procedure (NTP).
DLP-18 Turn On and Verify Office Power
Step 1 Using a voltmeter, verify the office battery and ground at the following points on the fuse and alarm panel:
a. To verify the power, place the black test lead of the voltmeter to the frame ground. Place the red test lead on the A-side connection and verify that it is between -42 VDC and -57 VDC. Place the red test lead on the B-side connection and verify that it is between -42 VDC and -57 VDC.
Note The voltages -42 VDC and -57 VDC are, respectively, the minimum and maximum amperages required to power the chassis.
b. To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red test lead on the A-side return ground and verify that no voltage is present. Place the red test lead on the B-side return ground and verify that no voltage is present.
Step 2 Complete one of the following to power up the node:
•If you are using a 80-amp fuse panel, insert a 20-amp fuse into the fuse position according to site practice.
•If you are using a 100-amp fuse panel, insert a 30-amp fuse into the fuse position according to site practice.
Step 3 Using a voltmeter, verify the shelf for -48 VDC battery and ground:
a. To verify the A-side of the shelf, place the black lead of the voltmeter to the frame ground. Place the red test lead to the BAT1 (A-side battery connection) red cable. Verify it reads between -42 VDC and -57 VDC. Then place the red test lead of the voltmeter to the RET1 (A-side return ground) black cable and verify that no voltage is present.
Note The voltages -42 VDC and -57 VDC are, respectively, the minimum and maximum amperages required to power the chassis.
b. To verify the B-side of the shelf, place the black test lead of the voltmeter to the frame ground. Place the red test lead to the BAT2 (B-side battery connection) red cable. Verify it reads between -42 VDC and -57 VDC. Then place the red test lead of the voltmeter to the RET2 (B-side return ground) black cable and verify that no voltage is present.
Step 4 Return to your originating procedure (NTP).
NTP-7 Install the Fan-Tray Assembly
Caution Do not operate an ONS 15454 without a fan-tray air filter. A fan-tray air filter is mandatory.
Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 Release 3.1 or later shelf assemblies (15454-SA-ANSI, 800-19857). It includes a pin that does not allow it to be installed in ONS 15454 shelf assemblies released before ONS 15454 Release 3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N 800-0714915454). Installing the 15454-FTA3 in a non-compliant shelf assembly may result in failure of the alarm interface panel (AIP), which in turn, will result in power loss to the fan-tray assembly.
Caution You must place the edge of the air filter flush against the front of the fan-tray assembly compartment when installing the fan tray on top of the filter. Failure to do so could result in damage to the filter, the fan tray, or both.
Caution Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the connectors on the back panel of the shelf assembly.
Note To install the fan-tray assembly, it is not necessary to move any of the cable-management facilities.
Step 1 Slide the fan tray into the shelf assembly until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.
Step 2 To verify that the tray has plugged into the backplane, check that the LCD on the front of the fan tray is activated and displays data.
Figure 1-10 shows the location of the fan tray.

Step 1 To route coaxial cables, complete the "DLP-28 Route Coaxial Cables" task.
Step 2 To route DS-1 twisted pair cables, complete the "DLP-29 Route DS-1 Twisted-Pair Cables" task.
Step 3 Continue with the "NTP-11 Install the Rear Cover" procedure.
DLP-28 Route Coaxial Cables
Step 1 Tie wrap or lace the coaxial cables according to local site practice and route the cables through the side cutouts on either side of the ONS 15454. The rubber coated edges of the side cutouts prevent the cables from chafing.
Step 2 Use short lengths of "pigtail" RG179 to terminate the shelf assembly.
Step 3 Use standard RG59 (735A) cable connected to the RG179 for the remainder of the cable run. When using a 10-foot section of the RG179, you can attach a maximum length of 437 feet of RG59 (735A). When using a 30-foot section of RG179, you can attach a maximum length of 311 feet of RG59 (735A).
When using the RG179 cable, the maximum distance available (122 feet) is less than the maximum distance available with standard RG59 (735A) cable (306 feet). The maximum distance when using the RG59 (734A) cable is 450 feet. The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. Attenuation rates are calculated using a DS-3 signal:
•For RG179, the attenuation rate is 59 dB/kft @ 22 MHz.
•For RG59 (735A), the attenuation rate is 23 dB/kft @ 22 MHz.
Use a figure of 5.0 for total cable loss when making calculations. Figure 1-22 shows an example of proper coaxial cable routing.
