N-Platform Hardware Installation and Safety Guide
Reliable earthing
Ensure that an external grounding connection is available for the product.
Follow these guidelines:
• For AC-powered products, use only the AC power cords that have been provided with the product.
Using other cords could be hazardous to your safety.
• For DC-powered products, ensure that the product is grounded to the ground termination connector
labeled with the IEC 60417-5019 symbol:
Always make the ground connection first when you install the product, ensuring that it is in place before
turning on the power or connecting any network cables. When disconnecting the product, remove the
ground connection last, only after the power has been completely turned off and all cables have been
disconnected. When the installation is done in a rack, the rack must be grounded to provide an adequate
ground location for the ground wire that is attached to the chassis.
ESD requirements
Damage from Electromagnetic Static Discharge (ESD) can occur when electronic components are
improperly handled.
Its results can be complete or intermittent system failures. Proper ESD protection is required whenever you
handle equipment. It is not necessary to open the product chassis to add or remove any components. The
following general grounding guidelines apply in the event that a power supply module or ZPHA module
must be replaced.
• Always use an ESD wrist strap when adding or removing components from the chassis.
• Avoid touching the circuit boards or connectors on all cards and modules.
• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body. ESD voltages on clothing can still cause damage.
• Place a removed component board-side-up on an antistatic surface or in a static-shielding container
that is also grounded to the same point as the IPS. If you plan to return the component to the factory,
immediately place it in a static-shielding container.
Hot swapping guidelines
Hot swapping allows you to remove and replace cards without disconnecting power to the system.
