Locating and Grounding the Cisco ONS 15310-MA ANSI and
ONS 15310-MA ETSI Chassis
Before locating and grounding the Cisco ONS 15310-MA ANSI and the ONS 15310-MA ETSI chassis,
you must complete the prerequisites mentioned in
ground point and attach a ground cable to the Cisco ONS15310-MA ANSI and ONS 15310-MA ETSI
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
Note
Remove any paint and other nonconductive coatings from the surfaces between the chassis ground and
Step 2
the rack frame ground posts. Clean the mating surfaces and apply an appropriate antioxidant compound
to the bare conductors.
Note
Note
Locate the ground connection points, which are located on the left, right, and bottom of the

ONS 15310-MA chassis. (See diagram 1 in
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.
Line up the holes on the lug with the holes on the ground connection point. Use two 10-32 screws to

and Figure 2.)
The ONS 15310-MA is installed in a weather-proof cabinet for outdoors installation, also known
as an Outside Plant (OSP) installation. A 1 inch (minimum) wide copper braid (with minimum
total strands count of 1050 x 36 AWG or 260 x 36 AWG) is required for ONS 15310-MA OSP
installations.
Additional ground cables may be added depending on local site practice. The
ONS 15310-MA 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.
