Note
Ground the Device
Before you begin this task, ensure that you have read and understood the safety warnings in the Preventing
ESD Damage section of the Safety Warnings handout.
Before you connect the power or turn on the power to the device, you must provide an adequate device ground
(earth) connection to your device.
This section describes how to ground the device. The grounding lug location is on the back panel of the device.
To ground the device:
1. Verify that the ground cable is connected to the top of the rack and according to local site practice.
Figure 25: Ground Lug
2. Attach one end of the shelf ground cable (No. 6 AWG cable) to the ground point on the rear of the router
using the specified dual-hole lug connector.
a. Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end
of the grounding cable.
b. Insert the stripped end of the grounding cable into the open end of the grounding lug.
c. Use the crimping tool to secure the grounding cable in the grounding lug.
d. Remove the adhesive label from the grounding pad on the chassis.

Ground the Device

e. Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and
insert the two #10-32 pan head Phillips screws with washers through the holes in the grounding lug
and into the grounding pad.
f. Ensure that the lug and cable do not interfere with other equipment.
g. Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your
site to ensure adequate earth ground.
Install the AC Power Cables
To install the AC power cables in the power supply slots:
1. Plug the power supply cord in to the power supply module.
2. Wrap the tie around the power supply cord.
3. Ensure that the power supply cord is secured to the power supply module.
4. Tighten the tie around the power supply cord as shown.
These images are for only representation purposes. Certain variants of Cisco NCS 540 routers don’t
include a tie for the power supply cord.
Note
Activate an AC Power Supply Module
Perform the following procedure to activate an AC power supply:
1. Plug the power cord into the power supply.
Install the Device

Install the Device
Install the AC Power Cables

2. Connect the other end of the power cord to an AC-input power source.
3. Verify power supply operation by checking if the respective power supply front panel LED (PS0 or PS1)
is green.
4. If the LEDs indicate a power problem, see Troubleshooting for troubleshooting information.
5. If you are also connecting a redundant AC power supply, repeat these steps for the second power source.
If you are connecting a redundant AC power supply, ensure that each power supply is connected to a
separate power source in order to prevent power loss in the event of a power failure.
Note
The operating voltage range is 90V-265VAC, 50/60Hz.
Install the DC Power Cables
When installing DC power supply, use 14AWG for longer cables and 14-16AWG for shorter cables,
90°C temperature rated cable. The recommended cable length is three meters maximum from source.
Note
• Always ensure that the building’s installation for short-circuit (overcurrent) protection does not
exceed 15A.
• We recommend you to use a circuit breaker or a fast acting fuse with a maximum DC rating, based
on the router variants for over current protection.

2. If the LEDs indicate any issues with power problem, see Troubleshooting.
3. If you are also connecting a redundant DC power supply, repeat these steps for the second power source.
If you are connecting a redundant DC power supply, ensure that each power supply is connected to a
separate power source in order to prevent power loss in the event of a power failure.
Note
The operating voltage range is -20V to -72VDC.
Port Connection Guidelines
To prevent damage to the fiber-optic cables, we recommend 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.

Activate a DC Power Supply Module

• 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 for 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.
Keep unused ports covered with dust caps in order to protect them from dust and insects.
Note
Connect to the Console Port
Before you begin:
• 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.
• Network cabling should already be routed to the location of the installed router.
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.
You can connect the router to the computer USB port using the following options:
•Connect Using USBA-A Cable
1. Use USBA-A cable to connect from the USB console port (USB CONS) on the router to the USB
port of the computer.
