Connecting Earth Ground to a PTX10000
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you
must connect the chassis to earth ground before you connect it to power.
For installations that require a separate grounding conductor to the chassis, you must attach a protective
earthing terminal bracket on the chassis. There are mounting holes for the terminal bracket on the left-rear
side of the chassis to connect to the earth ground (see Figure 100 on page 234).
NOTE: A ground connection to the protective earthing terminal is not required for an AC-powered
switch. The AC power cords provide adequate grounding when you connect the power supply in
the switch to a grounded AC power outlet by using the AC power cord appropriate for your
geographical location.
If an external ground connection is required, ensure that a licensed electrician has attached an appropriate
grounding lug to the grounding cable you supply. Using a grounding cable with an incorrectly attached lug
can damage the switch.
NOTE: Mount your router in the rack before attaching the grounding lug to the router. For the
PTX10008 and PTX10016, see:
•
Installing the PTX10008 into a Rack on page 209
•
Mounting a PTX10016 in a Four-Post Rack Using a Mechanical Lift
Ensure that you have the following parts and tools available:
•
An electrostatic discharge (ESD) grounding strap (provided).
•
Protective earthing terminal lug (provided).
•
Grounding cable for your PTX10000 (not provided)—The grounding cable must be 6 AWG (13.3 mm²),
minimum 90° C wire, or as permitted by the local code.
•
Grounding lug for your grounding cable (provided)—This bracket attaches to the lower left corner of the
PTX10000 router chassis next to PSU 5, providing a protective earthing terminal for the router. The
grounding lug required is a Panduit LCD6-10A-L or equivalent.
•
A Phillips screwdriver to tighten the two screws that are mounted on the chassis.
An AC-powered PTX10000 gains additional grounding when you plug the power supply in the router into
a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See
“PTX10000 Power Cables Specifications” on page 172.
