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.

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.

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

Page 18

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.

CHAPTER 3

• Keep your system components away from radiators and heat sources, and do not block cooling vents.

• Do not spill food or liquids on your system components, and never operate the product in a wet environment.

• Do not push any objects into the openings of your system components. Doing so can cause fire or electric shock by shorting out interior components.

• Position system cables and power supply cable carefully. Route system cables and the power supply cable and plug so that they are not stepped on or tripped over. Ensure that nothing is rests on your system component cables or power cable.

• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local and national wiring rules.

• If you turn off your system to avoid damage of system components, wait at least 30 seconds before turning it on again.

Cisco NCS 540 Router Hardware Installation Guide

Page 20

Site Planning Checklist

Use the following checklist to carry out all site planning tasks:

• The site meets environmental requirements.

• The site’s air conditioning system can compensate for the heat dissipation of the chassis.

• The floor space that the chassis occupies can support the weight of the system.

• Electrical service to the site complies with the safety with electricity requirements.

• The electrical circuit servicing the chassis complies with the power supply requirements.

• Console port wiring and cabling limitations have been considered in accordance to TIA/EIA-232F.

• The chassis Ethernet cabling distances are within prescribed limits.

• The equipment rack where the chassis is to be installed complies with prescribed requirements.

• When selecting rack location, safety, ease of maintenance, and proper airflow requirements have been considered.

Prepare for Installation

Site Power Guidelines

The chassis has specific power and electrical wiring requirements. Adhering to these requirements ensures reliable operation of the system. Follow these precautions and recommendations when planning your site power for the chassis:

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

• Connect each power supply to a separate input power source. Otherwise, it results in total power failure to the system due to a fault in the external wiring or a tripped circuit breaker.

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

• Check the power at your site before installation, and periodically after installation, to ensure that you are receiving clean power. If necessary, install a power conditioner.

• Provide proper grounding to avoid personal injury and damage to the equipment due to power surges or lightning striking power lines. The chassis ground must be attached to a central office or other interior ground system.

Caution

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.

Cisco NCS 540 Router Hardware Installation Guide

Page 21

Prepare for Installation

Note

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.

Electrical Circuit Requirements

Each chassis requires a dedicated electrical circuit. If you equip the device with dual-power feeds, provide a separate circuit for each power supply to avoid compromising the power redundancy feature.

The chassis supports both DC source or an AC source. Ensure that equipment grounding is present and observe power-strip ratings. Make sure that the total ampere rating of all the products plugged into the power strip does not exceed 80% of the rating.

Site Cabling Guidelines

Electrical Circuit Requirements

This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the chassis, consider the type of cable that is required for each component and 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.

Also, consider any additional interface equipment that you need, such as transceivers, hubs, switches, modems, channel service units (CSU), or data service units (DSU).

Before you install the chassis, have on hand all additional external equipment and cables. For information about ordering, contact a Cisco customer service representative.

The extent of your network and the distances between the network interface connections depend, in part, on the following factors:

• Signal type

• Signal speed

• Transmission medium

The distance and rate limits that are referenced in the following sections are the IEEE-recommended maximum speeds and distances for signaling purposes. Use this information as a guideline when planning your network connections before installing the chassis.

If wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the possibility of a lightning strike in your vicinity. The electromagnetic pulse due to lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

Asynchronous Terminal Connections

The chassis provides a console port to connect a terminal or computer for local console access. The port has an RJ-45 connector and supports RS-232 asynchronous data with distance recommendations that are specified in the IEEE RS-232 standard.

Cisco NCS 540 Router Hardware Installation Guide

Page 22

Interference Considerations

When wires are run for any significant distance, there is a risk of receiving stray signals on the wires as interference. If interference signals are strong, it results in data errors or equipment damage.

The following sections describe the sources of interference and how to minimize their effects on the chassis.

Electromagnetic Interference

All the equipment that is powered by AC current can propagate electrical energy that can cause EMI and possibly affect the operation of other equipment. The typical sources of EMI are equipment power cords and power service cables from electric utilities.

Strong EMI can destroy the signal drivers and receivers in the chassis. It can even create an electrical hazard by causing power surges through the power lines into installed equipment. These problems are rare, but could be catastrophic.

To resolve these problems, you need specialized knowledge and equipment that could consume substantial time and money. However, you can ensure that you have a properly grounded and shielded electrical environment, paying special attention to the need for electrical surge suppression.

Prepare for Installation

Radio Frequency Interference

When electromagnetic fields act over a long distance, radio frequency interference (RFI) may be propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more EMI on the wiring.

If you use a twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal.

Lightning and AC Power Fault Interference

If signal wires exceed the recommended cabling distances, or if signal wires pass between buildings, you may encounter a lightning strike on the chassis.

The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple enough energy into unshielded conductors and damage or destroy electronic equipment. For such problems, you must consult with RFI and EMI experts to ensure adequate electrical surge suppression and shielding of signal cables in your operating environment.

Tools and Equipment

You need the following tools and equipment to install and upgrade the device and its components:

• ESD-preventive cord and wrist strap

• Antistatic mat or antistatic foam

• Number 1 and Number 2 Phillips-head screwdrivers

• #12-24 pan-head screws to secure the device to the equipment rack.

• Cables for connecting to network ports (based on the configuration)

• Ethernet hub, switch, or PC with a network interface card for connecting to the Ethernet ports

• Console terminal that is configured for 9600 baud, 8 data bits, no parity, no flow control, and 1 stop bit.

• Console cable for connecting to the console port

Install the Device

Connect to the Console Port

To prevent damage to the fiber-optic cables, Cisco recommends that you keep the transceivers disconnected from their fiber-optic cables when installing the transceiver in the line card. Before removing a transceiver from the router, remove the cable from the transceiver.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

• Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers. The router is typically grounded during installation and provides an ESD port to which you can connect your wrist strap.

• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions can shorten its useful life.

• Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be kept below 0.35 dB.

• Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.

• Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors when they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.

• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other contamination.

• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.

Connect to the Console Port

Before you create a network management connection for the router or connect the router to the network, you must create a local management connection through a console terminal and configure an IP address for the router. You also can use the console to perform the following functions (each of which can be performed through the management interface after you make that connection):

• Configure the router using the command-line interface (CLI).

• Monitor network statistics and errors.

• Configure Simple Network Management Protocol (SNMP) agent parameters.

• Download software updates.

The system console port is an RJ-45 receptacle for connecting a data terminal to perform the initial configuration of Cisco NCS 540 fixed-port chassis. The console cable is shipped with the hardware.

Cisco NCS 540 Router Hardware Installation Guide

Page 34

Connect to the Console Port

Figure 10: Console Port

Follow this procedure to connect a data terminal to the console port.

Before you begin

Install the Device

• The router must be fully installed in its rack, connected to a power source, and grounded.

• The necessary cabling for the console, management, and network connections must be available.

• An RJ-45 rollover cable and DB9F/RJ-45 adapter are provided in the router accessory kit.

• Network cabling should already be routed to the location of the installed router.

Install and Remove QSFP+/QSFP28 Transceiver Modules

This section provides the installation, cabling, and removal instructions for the 40-Gigabit Quad Small Form-Factor Pluggable Plus (QSFP+) and 100 Gigabit (QSFP28) transceiver modules. The modules are hot-swappable input/output (I/O) devices that connect the system’s module port electrical circuitry with either a copper or a fiber-optic network.

Overview

The 40-Gigabit (GE) QSFP+ and 100 Gigabit (QSFP28) transceiver module is a hot-swappable, parallel fiber-optical module with 4 independent optical transmit and receive channels. These channels can terminate in another 40-Gigabit QSFP+ transceiver, or the channels can be broken out to 4 separate 10-Gigabit SFP+ transceivers. The QSFP+ transceiver module connects the electrical circuitry of the system with an optical external network.

The following figure shows the 40-Gigabit optical QSFP+ transceiver. The transceiver is used primarily in short reach applications in switches, routers, and data center equipment where it provides higher density than SFP+ modules. The 100-Gigabit optical QSFP28 transceiver is similar to the 40-Gigabit optical QSFP transceiver.

Electricity section of the Safety Warnings handout topic.

Configuring the Cisco NCS 540 involves these tasks:

• Create the Initial Router Configuration, on page 41

• Verify Device Installation, on page 43

Create the Initial Router Configuration

You must assign an IP address to the router management interface so that you can then connect the router to the network.

When you initially power up the router, it boots up and asks a series of questions to configure the router. To enable you to connect the router to the network, you can use the default choices for each configuration except for the IP address, which you must provide.

CHAPTER 5

Note

Be aware of the router's unique name to identify it among the devices in the network.

Before you begin

• A console device must be connected with the router.

• The router must be connected to a power source.

• Determine the IP address and netmask needed for the Management interfaces: MgmtEth0/RP0/CPU0/0 and MgmtEth0/RP1/CPU0/0:

Step 1 Power up the router.

The LEDs on each power supply light up (green) when the power supply units are sending power to the router, and the software asks you to specify a password to use with the router.

Step 2 When the system is booted up for the first time, a new username and a password is to be created. The following prompt

appears:

Step 3 Enter a new password to use for this router.

Configure the Device

The software checks the security strength of your password and rejects your password if it is not considered to be a strong password. To increase the security strength of your password, make sure that it adheres to the following guidelines:

• At least eight characters

• Minimizes or avoids the use of consecutive characters (such as "abcd")

• Minimizes or avoids repeating characters (such as "aaa")

• Does not contain recognizable words from the dictionary

• Does not contain proper names

• Contains both uppercase and lowercase characters

• Contains numbers as well as letters

Note

Tip

Clear text passwords cannot include the dollar sign ($) special character.

If a password is trivial (such as a short, easy-to-decipher password), the software rejects the password configuration. Be sure to configure a strong password as explained in this step. Passwords are case sensitive.

If you enter a strong password, the software asks you to confirm the password.

Step 4 Reenter the password.

When you enter the same password, the software accepts the password .

Step 5 Enter the IP address for the management interface.

Step 6 Enter a network mask for the management interface.

Step 7 The software asks if you need to edit the configuration. Enter no to not edit the configuration.

• System messages displayed

• SNMP notifications (if configured) sent

• Log environmental alarm event triggered (can be reviewed by running the show alarm command).

• For sensor 2 (intake sensor), the following actions occur:

• If the threshold is exceeded in a switching card, only that card is shut down.

• If the threshold is exceeded in an active route processor card with HA-standby or standby present, only that route processor card is shut down and the standby route processor card takes over.

• If you do not have a standby route processor card in your router, you have up to 2 minutes to decrease the temperature. During this interval, the software monitors the temperature every 5 seconds and continuously sends system messages as configured.

CHAPTER 6

Caution

Step 1 Unscrew the captive thumbscrew at the front of the fan tray.

If you cannot replace a fan tray within three minutes, we recommend that you leave it in the chassis until you are prepared to replace it within that specified time limit.

Note

If you remove more than one fan tray at a time during operations, the router allows up to 2 minutes of operations before shutting down, unless you replace extra missing fan trays within that time. If the router senses an over temperature condition when multiple fan trays are removed, the shutdown can occur in less than 2 minutes.

Step 2 Pull the fan tray to remove the fan tray to be replaced.

Step 3 Hold the fan module with the LED and PID label at the top.

Step 4 Align the fan module to the open fan tray slot in the chassis and press the module all the way into the slot until the left

and right latches click and lock on the chassis.

Step 5 If the chassis is powered on, listen for the fans. You should immediately hear them in operation. If you do not hear them,

ensure that the fan module is inserted completely in the chassis.

Step 6 Verify that the fan module LED is green. If the LED is not green, one or more fans are faulty.

Replace Power Supply

The router provides the choice of two different power supplies:

• DC power—The DC power supply uses 2-position terminal block-style connector with positive latching/securing and labeled connections for +24/48V, GRD, -24/48V. The terminal block connector is of suitable size to carry the appropriate AWG wire size to handle the input current of the power supply. No ON/OFF switch is provided.

• AC power—The AC power supply has an IEC 320-type power receptacle and a 15 Amp service connector. You can use standard right angle power cords with the AC power supply. The power supply includes a power cord retainer. No ON/OFF switch is provided.

You can install dual power supplies for redundancy.
