The Calix E7-20 ground system can be connected to a Common Bonding Network (CBN) or
Isolated Bonding Network (IBN).
Note:
For environments that employ an IBN scheme, the low voltage and frame grounds on
the E7-20 shelf are isolated from the input power DC-return.
The installation kit includes a 12-foot ground cable, plus hardware to attach it to the E7-20
frame ground. The grounding terminal for anti-static wrist strap connection is located on the
left side of the chassis.
