Unpacking and Installing the Cisco ONS 15454 Four-Shelf and Zero-Shelf Bay Assembly
78-13271-05
Install the Power and Ground
Note When terminating battery and battery return connections as shown in Figure 29 on page 31,
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 29 on
page 31.
Step 11 To power up the node, insert the correct fuse in the correct fuse position according to site practice.
