Basic guidelines for DC-powered systems include the following:

• Each chassis power supply has its own dedicated input power source. The source must comply with the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, and IEC 60950 standards.

• Protect the circuit by a dedicated two-pole circuit breaker. Ensure that the circuit breaker is sized according to the power supply input rating and local or national code requirements.

• The circuit breaker is considered as the disconnect device and is easily accessible.

Cisco NCS 540 Router Hardware Installation Guide

Guidelines for AC-Powered Systems

• The system ground is the power supply and chassis ground.

• Use the grounding lug to attach a wrist strap for ESD protection during servicing.

• Do not connect the DC return wire to the system frame or to the system-grounding equipment.

• Ensure that the DC return is grounded at the source side.

Guidelines for AC-Powered Systems

Basic guidelines for AC-powered systems include the following:

• Each chassis power supply has its own dedicated branch circuit.

• Ensure that the circuit breaker is sized according to the power supply input rating and local or national code requirements.

• The AC power receptacles that are used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles must connect to protective earth ground at the service equipment.

Prevent Power Loss

Use the following guidelines to prevent power loss to the device:

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

• In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the device, which can have substantial current-draw fluctuations due to bursty data traffic patterns.

Safety Warnings

Determining power requirements is useful for planning the power distribution system to support the device.

Preventing ESD Damage

Warning

Ground this equipment. Use a green and yellow 6-AWG ground wire to connect the host to earth ground during normal use. Statement 383

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD may occur when electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. When removing and replacing modules, always follow these ESD prevention procedures:

• Ensure that the device chassis is electrically connected to earth ground.

• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

• If no wrist strap is available, ground yourself by touching a metal part of the chassis.

• When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use available ejector levers or captive installation screws, if any, to release the bus connectors from the backplane or midplane.

Cisco NCS 540 Router Hardware Installation Guide

Safety Warnings

Preventing ESD Damage

• Handle components by only their handles or edges; do not touch the printed circuit boards or connectors.

• Place a removed component board side up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.

• 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.

• Never attempt to remove the printed circuit board from the metal carrier.

For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. Maintain the value between 1 and 10 Mohm.

Network Timing Interfaces

External Alarm Inputs

The router supports four dry contact alarm inputs through an RJ-45 jack at the rear panel.

• Normally Open—indicates that no current flows through the alarm circuit and the alarm is generated when the current is flowing.

Each alarm input can be provisioned as critical, major, or minor.

Console

The RS232 console port provides transmission (Tx), reception (Rx), and ground (Gnd).

Cisco NCS 540 Router Hardware Installation Guide

USB Console

A single USB 2.0 Type-A receptacle on the front panel of the router provides console access to ROMMON, Cisco IOS-XE and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for connection to an external host computer. This interface requires the use of a Type-A to Type-A connector instead of a standard USB cable.

Note

Use of the USB console is mutually exclusive of the RS232 console port. This interface requires the use of a Type-A to Type-A USB cable.

Online Insertion and Removal

The router supports the following OIR operations:

• When an SFP is removed, there is no effect on traffic flowing on other ports.

Cisco NCS 540 Router Overview

• When an SFP is installed, the system initializes that port for operation that is based on the current configuration. If the inserted SFP is incompatible with the current configuration for that port, the port does not become operational until the configuration is updated.

• Both power supplies are installed and active, the load may be shared between them or a single PSU could support the whole load. When a power supply is not working or the input cable is removed, the remaining power supply takes the entire load without disruption.

Power Supply (N540-PWR400-A and N540-PWR400-D)

The Cisco NCS 540 router supports two AC or DC power supplies, which power the router. The second power supply ensures redundancy in the system. Both power supplies support hot swapping capabilities.

Fan Assembly (N540-FAN)

Cisco NCS 540 Router comes with 4 individual fan modules. Fans are located at the rear panel and support hot swapping. Fan flow is supported only on the forward direction from front to back.

Note

The system can function with a single fan failure but if more than one fan is faulty then the system shuts down.
