Before supplying power to the PTX10008, ground the chassis and install the power supplies appropriate to your system
(AC, DC, and HVAC/HVDC)
Ground the PTX10008
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 20).
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.
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 PTX10008 (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 router chassis
next to the bottom power supply, 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 PTX10008 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.
To connect earth ground to a PTX10008 chassis:
1. Verify that a licensed electrician has attached the cable lug (provided in the accessory kit) to the grounding cable.
2. Connect the other end of the grounding cable to a proper earth ground, such as the rack in which the router is mounted.
3. Attach an ESD grounding strap to your bare wrist, and connect the strap to the ESD grounding point next to the
earthing posts (see Figure 19).
