Port Connection Guidelines

Depending on the chassis and installed line cards, you can use Quad Small Form-Factor Pluggable Plus

(QSFP+), QSFP28, SFP, SFP+, CFP-DCO, and RJ-45 connectors to connect the ports on the line cards to

other network devices.

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

Connect Router to the Network

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.

Statement 1051—Laser Radiation

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or

view directly with optical instruments.

Warning

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 NCS 5500 fixed-port chassis. The console cable is shipped with the hardware.

port

Follow this procedure to connect a data terminal 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 are provided in the router accessory kit.

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

Step 1 Set your terminal to these operational values: 115200 bps, 8 data bits, no parity, 2 stop bits (115200 8N1).

Step 2 Attach the terminal end of the cable to the interface port on the data terminal.

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.

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

Note

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.

Connect Router to the Network

Create the Initial Router Configuration

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:

!!!!!!!!!!!!!!!!!!!! NO root-system username is configured. Need to configure root-system username.

!!!!!!!!!!!!!!!!!!!!

--- Administrative User Dialog ---

Enter root-system username:

% Entry must not be null.

Enter root-system username: root

Enter secret:

Use the 'configure' command to modify this configuration.

User Access Verification

Username: root

Password:

RP/0/RP0/CPU0:ios#

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

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

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

Note

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.

Tip

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.

Step 8 The software asks if you need to save the configuration. Enter yes to save the configuration.

Connect Router to the Network

Create the Initial Router Configuration

Connect to the Management Ethernet Port

The management Ethernet port provides out-of-band management, which enables you to use the command-line

interface (CLI) to manage the router by its IP address. This port uses a 10/100/1000 Ethernet connection with

an RJ-45 interface.

To prevent an IP address conflict, do not connect the management Ethernet port until the initial configuration

is complete.

Note

To connect cables to the system management port, attach Category 5 cables directly to the RJ-45 receptacle

on the management Ethernet port.

Connect to the Management Ethernet Port

To comply with GR-1089-CORE, Railway EN 50121, Smartgrid IEC 61850, and IEEE 1613, the intra-building

port(s) of the equipment must use shielded intra-building cabling/wiring that is grounded at both ends.

Note

Before you begin

You must have completed the initial router configuration.

Step 1 Plug the cable directly into the RJ-45 receptacle.

Step 2 Connect the network end of your RJ-45 cable to a switch, hub, repeater, or other external equipment.

Installing and Removing Modular Port Adapters

The following sections describe how to install or remove MPA on the Cisco NCS 55A2-MOD-S , Cisco NCS

55A2-MOD-SE-S, Cisco NCS-55A2-MOD-HX-S,Cisco NC55A2-MOD-SE-H-S, and Cisco NCS

55A2-MOD-HD-S router.

Handling Modular Port Adapters

Each modular port adapter (MPA) circuit board is mounted to a metal carrier and is sensitive to electrostatic

discharge (ESD) damage.

Always handle the MPA by the carrier edges and handle; never touch the MPA components or connector pins

(See the figure below).

Caution

When a bay is not in use, a blank MPA Slot Filler must fill the empty bay to allow the router or switch to

conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across

the installed modules. If you plan to install a MPA in a bay that is not in use, you must first remove the blank.

Online Insertion and Removal

Cisco NCS 5500 series modular port adapters (MPAs) support online insertion and removal (OIR).

Modular port adapters (MPAs) support the following types of OIR:

• Soft OIR

Soft OIR uses the IOS XR hw-module subslot rack/slot/subslot reload,hw-module subslot

rack/slot/subslot shutdown, and no hw-module subslot rack/slot/subslot shutdown commands to

complete online insertion and removal.

• Managed OIR

A managed online insertion and removal of Modular port adapters (MPAs) is comprised of the following

steps:

• Shut down the MPA with the hw-module subslot rack/slot/subslot shutdown command.

• Confirm that the LEDs have gone from green to off.

• Execute the do show platform command to verify that the MPA to be removed is in the disabled

state.

• Physically remove the MPA to be replaced.

• Physically insert the replacement MPA

• Return the MPA to the up state with the no hw-module subslot rack/slot/subslot shutdown

command.

• Hard OIR

You can perform the OIR in a running system, by not executing any commands:

Online Insertion and Removal

• Loosen and remove the right ejector screw.

• Loosen and remove the left ejector screw.

• Remove and replace the MPA.

Modular Port Adapter Installation and Removal

This section provides step-by-step instructions for removing and installing a modular port adapter (MPA) in

a Cisco NCS 55A2-MOD-S, Cisco NCS 55A2-MOD-SE-S or Cisco NCS 55A2-MOD-HD-S router.

After you remove the MPA from the slot, wait for 60 seconds before you reinsert the MPA.

Note

After you unscrew both ejector screws, wait for 15 seconds before removing MPA from the slot.

Note

During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly

touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94

Warning

To remove and install a MPA, do the following:

1. To insert the MPA, locate the guide rails inside the chassis that hold the MPA in place. They are at the

bottom left and bottom right of the MPA slot and are recessed about an inch.

2. Carefully slide the MPA all the way in the chassis until the MPA is firmly seated in the MPA interface

connector. When fully seated, the MPA might be slightly behind the faceplate.

The MPA will slide easily into the slot if it is properly aligned on the tracks. If the MPA does not slide easily,

do NOT force it. Remove the MPA and reposition it, paying close attention to engaging it on the tracks. Push

the MPA inside the slot until you hear a click. Continue to push the MPA further until you hear a second click.

The MPA is fully seated only after the second click is heard.

Note

3. After the MPA is properly seated, use a number 2 Phillips screwdriver to tighten the captive screws on

the MPA. Ensure that you first tighten the right screw and then the left.

Avoid over torquing the MPA captive screws when installing the MPA. Tighten the captive screws on the

MPA to a torque of 6 +/-0.5 inch-pound.

Note

4. To remove the MPA from the chassis, use a number 2 Phillips screwdriver to loosen the captive screws

on the MPA. Ensure that you first loosen the right screw and then the left.

5. Grasp the MPA and pull the MPA from the chassis. (You have already disconnected the cables from the

MPA.)

Install and Remove Transceiver Modules

Install and Remove SFP Modules

Before you remove or install an SFP or SFP+ module, read the installation information in this section.

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or

view directly with optical instruments. Statement 1051

Warning

Protect the line card by inserting a clean SFP/SFP+ module cage cover, shown in the figure below, into the

optical module cage when there is no SFP or SFP+ module installed.

Caution

Figure 6: SFP/SFP+ Module Cage Cover

Protect the SFP or SFP+ modules by inserting clean dust covers into them after the cables are removed. Be

sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another

module. Avoid getting dust and other contaminants into the optical ports of your SFP or SFP+ modules,

because the optics do not work correctly when obstructed by dust.
