Grounding the Chassis
Two system (earth) grounding holes are provided in an enclosure near the top of
the chassis.
Shelf Grounding Guidelines
To make an adequate grounding connection, you need the following parts and
tools:
•
Grounding lug.
•
Lug mounting adapter.
•
Two M4 (metric) hex-head screws with locking washers.
•
One grounding wire. We recommend 6 AWG. The length of the grounding
wires depends on the location of your Cisco ONS 15540 ESPx within the site
and its proximity to proper grounding facilities.
•
Number 2 Phillips head screwdriver.
•
Crimping tool. This tool must be large enough to accommodate the girth of
the grounding lug when you crimp the grounding cable into the lug.
•
Wire-stripping tool.
Note
The grounding lugs, lug mounting adapter, and M4 screws are included in your
accessory kit that ships with the system.
