Prepare for Installation

• The redundant power option provides a second, identical power supply to ensure uninterrupted power

• Connect each power supply to a separate input power source. Otherwise, it results in a total power failure

• To prevent loss of input power, ensure that the maximum load on each circuit is within the current ratings

• Check the power at your site before installation, and periodically after installation, to ensure that you are

• Provide proper grounding to avoid personal injury and damage to the equipment due to power surges or

Site Cabling Guidelines

This section contains guidelines for wiring and cabling at your site. When preparing your site for network

connections to the router, consider the type of cable required for each component, and the cable limitations.

Consider the distance limitations for signaling, ElectroMagnetic Interference (EMI), and connector

compatibility. Possible cable types are fiber, thick or thin coaxial, foil twisted-pair, or unshielded twisted-pair

cabling.

lightning striking power lines. The chassis ground must be attached to a central office or other interior

ground system.

Cisco N540-6Z18G-SYS-A/D router has single power supply unit.

Statement 1045 Short-Circuit Protection

This product requires short-circuit (overcurrent) protection to be provided as part of the building

installation. Install only in accordance with national and local wiring regulations.

The router requires external surge protection devices for installations where electrical surges higher than

4KV common mode and 2KV differential mode are expected. Failure to do so can result in permanent

damage to the router. For Cisco N540-6Z18G-SYS-A/D router, 2KV common mode and 1KV differential

modes are supported.

The chassis installation must comply with all the applicable codes, and is approved for use with only

copper conductors. The ground bond-fastening hardware must be compatible and preclude loosening,

deterioration, and electrochemical corrosion of hardware and joined material. Attachment of the chassis

ground to a central office or other interior ground system must be made with a 6-AWG gauge wire

copper ground conductor.
