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

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

Connect to the Management Ethernet Port
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.
Note
To prevent an IP address conflict, do not connect the management Ethernet port until the initial configuration
is complete.
To connect cables to the system management port, attach Category 5 cables directly to the RJ-45 receptacle
on the management Ethernet port.

Installing and Removing Modular Port Adapters
Note
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.
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.
Caution
Always handle the MPA by the carrier edges and handle; never touch the MPA components or connector pins
(See the figure below).
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:
