Cisco ONS 15454 DWDM Procedure Guide, R8.0
78-17704-02
Chapter 1 Install the Shelf and Common Control Cards
NTP- G16 Connect the Office Ground to the ONS 15454 ANSI
Step 1
Verify that the office ground cable (#6 AWG stranded) is connected to the top of the bay according to
local site practice.
Step 2
Attach one end of the shelf ground cable (#10 AWG) to the right side of the backplane ground nut. See
for the location of the ground on the backplane.
Note
When terminating a frame ground, use the Kepnut provided with the ONS 15454 and tighten it
to a torque specification of 31 in-lb. The Kepnut provides a frame ground connection that
minimizes the possibility of loosening caused by rotation during installation and maintenance
activity. The type of prevention the Kepnut provides for the frame ground connection is
inherently provided by the terminal block for battery and battery return connections.
