Grounding the CPE
This section provides information for installing a proper ground for Calix’s Customer
Premises Equipment (CPE), which includes various models of the ONT. This document also
provides NEC requirements for installing a ground.
Grounding Options
The grounding requirements for various ONT models differ depending on where the unit is
installed. Exterior mounted ONTs require a direct bond to the buildings primary earth
electrode. For internally mounted ONTs, or ONTs which do not incorporate the Calix
enclosure, It is allowable to connect to the buildings electrical ground circuit.
Important:
It is absolutely critical that the MEM, when mounted, be connected to a known
good ground. Failure to properly ground the unit during installation will cause loss of
services.
