General Site Guidelines

Efficient device operation requires proper site planning and maintenance and proper layout of the equipment,
rack or cabinet (if used), and wiring closet.
To plan and create an acceptable operating environment for your device and prevent environmentally
caused equipment failures:
Keep the area around the chassis free from dust and conductive material, such as metal flakes.
Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that
exhaust from other equipment does not blow into the intake vents of the device.
Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the
equipment. Static discharge can cause components to fail completely or intermittently over time.
Install the device in a secure area, so that only authorized personnel can access the device.

PTX1000 Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the PTX1000 must be
adequately grounded before power is connected to ensure proper operation and to meet safety and
electromagnetic interference (EMI) requirements. To ground a PTX1000, connect a grounding cable to
earth ground and then attach it to the chassis grounding points.
WARNING:
location. It has a separate protective earthing terminal provided on the chassis in
addition to the grounding pin of the power supply cord. This separate protective
earthing terminal must be permanently connected to earth ground for installations
that require a separate grounding conductor to the chassis.
WARNING:
used for SFP+, QSFP+, and QSFP28 ports must be shielded and grounded at both
