Locating and Grounding the Cisco ONS 15310-CL ANSI Chassis
Before locating and grounding the Cisco ONS 15310-CL ANSI chassis, you must complete the
prerequisites mentioned in
ground cable to the Cisco ONS 15310-CL ANSI chassis:
Verify that the office ground cable is connected to the top of the rack according to local site practice.
Step 1
(See
Figure 1
Remove any paint and other nonconductive coatings from the surfaces between the shelf ground and the
Step 2
rack frame ground posts. Clean the mating surfaces and apply an appropriate antioxidant compound to
the bare conductors.

Step 3
Using the 10-32 screws that came with the ship kit, attach one end of the chassis ground cable to the
ground connection point located on the center of the rear panel as you face the chassis. Using a wire
stripper, strip 0.875 inches (2.22 cm) from the end of the ground cable.
Crimp the two-hole lug to the ground cable.
Step 4
Step 5
Line up the holes on the lug with the holes on the ground connection point, located at the center of the
rear panel as you face the chassis. Use two 10-32 screws to attach the lug to the ground connection point.

Additional ground cables may be added depending on local site practice. The
ONS 15310-CL ANSI chassis is designated only for a Common Bonding Network (CBN),
according to the GR-1089-CORE Issue 4 (sec 9.3) definitions.
The DC power battery return (BR) terminal or positive terminal must be grounded at the source
end (power feed or DC mains power end). The DC power BR input terminal is not connected to
the equipment frame (chassis), so it is configured as DC-I according to the GR-1089-CORE,
Issue 4 (sec 9.8.3) definitions.
