Note If the system loses power or both TCC+ cards are reset, 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 "NTP-25 Set Up Name, Date, Time, and Contact Information" section.
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 1-10 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 1-10 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 1-10, follow a torque specification of 10 in-lbs. 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. This type of prevention is inherently provided by the terminal block for battery and battery return connections.
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 1-10.
Step 11 To power up the node, insert the correct fuse in the correct fuse position according to site practice.
Step 12 Return to your originating procedure (NTP).

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.
Note When using the RG179 cable with SMB connectors, remember that the maximum distance available with the RG179 cable is less than the maximum distance available with standard RG59 cable. If you only use the RG179, the maximum available distance is 50 feet versus the 450 feet available with the larger RG59 cable.
Step 2 Use short lengths of "pigtail" RG179 to terminate the shelf assembly.
Step 3 Use standard RG59 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. When using a 30-foot section of RG179, you can attach a maximum length of 311 feet of RG59.
The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. The attenuation rate for RG59 cable (based on testing with Belden 923, the equivalent of 328A cable) is ~1.0 dB/100 feet at 22 Mhz (DS-3 data rate). The attenuation rate of RG179 is
