Locating and Grounding the Cisco ONS 15454 ANSI Chassis

Before locating and grounding the Cisco ONS 15454 ANSI chassis, you must complete the prerequisites
mentioned in
the Cisco ONS 15454 ANSI chassis:
Verify that the office ground cable is connected to the top of the bay and the office ground, according to
Step 1
local site practice. (See
Note
Note
Remove any paint and other nonconductive coatings from the surfaces between the chassis ground and
Step 2
bay frame ground point. Clean the mating surfaces and apply appropriate antioxidant compound to the
bare conductors.
Step 3 Attach one end of the shelf ground cable to the ground point on the chassis using the specified dual-hole
lug connector. (See diagrams 1 and 2 in
Step 4 Attach the other end of the shelf ground cable to the bay frame using a dual-hole lug connector according
to the equipment bay frame specifications. (See Diagram 3 in

Figure 1 and
Additional ground cables may be added depending on local site practice. The ONS 15454 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.
