Connecting the Chassis to Ground
Connecting the CSS 11503 or CSS 11506 chassis to earth ground is required for
all DC-powered installations, and any AC-powered installation where compliance
with Telcordia (formerly Bellcore) grounding requirements is necessary. Have the
recommended tools and supplies available before you begin this procedure (see
Table 2-8).
Warning
Never defeat the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable
grounding is available.
Tools and Supplies
The accessory kit shipped with the CSS contains the following items used in this
procedure:
• One 2-hole grounding lug (Panduit no. LCD6-10A-L)
• Two M5 screws for the grounding lug
Table 2-8 lists the other tools, equipment, and supplies that you need to connect
system ground to the chassis. These are items that you must supply.
