Depending on the chassis, you can use Quad Small Form-Factor Pluggable Plus (QSFP+), QSFP28, SFP28, and RJ-45 connectors to connect the ports on the router 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 router. 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:
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.
Note For location of ports on the routers, see Network Interfaces.
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):
The system console port is an RJ-45 receptacle for connecting a data terminal to perform the initial configuration of NCS 5700 chassis.
Follow this procedure to connect a data terminal to the console port.
Before you begin
Procedure
Step 1 Set your terminal to these operational values: 115200 bps, 8 data bits, no parity, 1 stop bits (115200 8N1).
Step 2 Attach the terminal end of the cable to the interface port on the data terminal.
Step 3 Attach the other end of the cable to the console port.
Table 1: RJ-45 Straight-through Cable Pin-outs
You must assign an IP address to the router management interface so that you can then connect the router to the network.
After you boot the router, follow the guided setup/prompts 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 These routers are designed to boot up in less than 30 minutes, provided the neighboring devices are in full operational state.
Note Note down the router's unique name. It helps to identify the router among the devices in the network.
Before you begin
Procedure
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. The Administrative User Dialog prompt appears.
Step 2 When the system is booted up for the first time, you must enter root-system username. Use the default username and password that is provided to you. Later, you can create new username and password. 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: cisco
Enter secret:
Use the 'configure' command to modify this configuration. User Access Verification
Username: cisco Password:
RP/0/RP0/CPU0:ios#
Note Username is cisco. Reach out to your accounts team to obtain the password. You can later modify the password in Step 3.
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:
Note Clear text passwords cannot include the dollar sign ($) special character.
Tip 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.
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.
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.
Procedure
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.
The RJ-45 cable is available on the Management port. To access the RJ-45 cable, perform the following steps:
Note When the router is fully operational, all ports are populated with cables. It becomes difficult to access the RJ-45 cable using bare hands. Hence the below procedure is recommended to remove RJ-45 cable from the management port.
Figure 2: Remove RJ-45 Cable from the Jack
Before you remove or install an SFP28 or SFP+ module, read the installation information in this section.
Note The Cisco NCS 57B1 router has only QSFP-DD sockets, therefore you need QSA module (QSFP to SFP+ Adapter) CVR-QSFP-SFP10G to support SFP+ module.
Note The Cisco NCS-57C3-MOD router has three rows of SFP28 ports. In the top row, install SFP28 transceivers with the electrical connectors on the bottom. In the two bottom rows, install SFP28 transceivers with the electrical connectors on the top.
Figure 3:QSFP to SFP+Adapter
Insert CVR-QSFP-SFP10G in to the QSFP-DD port of the line card, followed by the insertion of the SFP+ pluggable.
Use the show inventory command to get details of the Cisco devices that are installed in the router. The adapter details are displayed.
Note The CVR-QSFP-SFP10G support is expected in a future release. Therefore, in release 7.3.15 SFP+ modules can't be used.
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.
Protect the line card by inserting a clean SFP+ module cage cover, shown in the figure below, into the optical module cage when there is no SFP+ module installed.
Figure 4:SFP + Module Cage Cover
Protect the 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+ modules, because the optics do not work correctly when obstructed by dust.
We strongly recommended that you do not install or remove the SFP+ module with fiber-optic cables attached to it because of the potential of damaging the cable, the cable connector, or the optical interfaces in the module. Disconnect all cables before removing or installing an SFP+ module. Removing and inserting a module can shorten its useful life, so you should not remove and insert modules any more than is absolutely necessary.
Note When installing an SFP+ module, you should hear a click as the triangular pin on the bottom of the module snaps into the hole in the receptacle. The click indicates that the module is correctly seated and secured in the receptacle. Verify that the modules are completely seated and secured in their assigned receptacles on the line card by firmly pushing on each SFP+ module.
The bale clasp SFP+ module has a clasp that you use to remove or install the module (see the figure below).
Figure 5:Bale Clasp SFP+Module
To install this type of SFP+ module, follow these steps:
Procedure
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Close the bale clasp before inserting the SFP+ module.
Step 3 Insert the QSA module (CVR-QSFP-SFP10G) in to the port. Line up the SFP+ module with the QSA module and slide it into the module.
Note When installing an SFP+ module, you should hear a click as the triangular pin on the bottom of the SFP+ module snaps into the hole in the receptacle. This click indicates that the module is correctly seated and secured in the receptacle. Verify that the SFP+ modules are completely seated and secured in their assigned receptacles on the line card by firmly pushing on each SFP+ module. Use the QSA adapter for using SFP+ modules.
To remove this type of SFP+ module, follow these steps:
Procedure
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Disconnect and remove all interface cables from the ports; note the current connections of the cables to the ports on the line card.
Step 3 Open the bale clasp on the SFP+ module with your index finger, as shown in the figure below. If the bale clasp is obstructed and you cannot use your index finger to open it, use a small flat-blade screwdriver or other long, narrow instrument to open the bale clasp.
Step 4 Grasp the SFP+ module between your thumb and index finger and carefully remove it from the port, as shown in the figure below.
Note This action must be performed during your first instance. After all the ports are populated, this may not be possible.
Figure 6: Removing a Bale Clasp SFP+Module
Step 5 Place the removed SFP+ module on an antistatic mat, or immediately place it in a static shielding bag if you plan to return it to the factory.
Step 6 Protect your line card by inserting a clean SFP+ module cage covers into the optical module cage when there is no SFP+ module installed.
This section provides the installation, cabling, and removal instructions for the QSFP-DD transceiver modules. The modules are hot-swappable I/O devices that connect the system's module port electrical circuitry with either a copper or a fiber-optic network.
The following figure shows a 400-Gigabit QSFP-DD optical 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 100GE/400GE QSFP-DD optical transceiver and 100-Gigabit QSFP28 optical transceiver are similar to the 40-Gigabit QSFP+ optical transceiver.

Step 8 Press firmly on the front of the QSFP+ or QSFP28 transceiver module with your thumb to fully seat the transceiver in the module's transceiver socket (see the below figure).
If the latch is not fully engaged, you might accidentally disconnect the QSFP+ or QSFP28 transceiver module.
Figure 13: Seating the 40-Gigabit QSFP+ or 100-Gigabit QSFP28 Transceiver Module (Optical Transceiver Equipped with a Bail-Clasp Latch Shown)
Step 9 For optical QSFP+ or QSFP28 transceiver modules, reinstall the dust plug into the QSFP+ or QSFP28 transceivers optical bore until you are ready to attach the network interface cable. Do not remove the dust plug until you are ready to attach the network interface cable.
Before you begin
Before you remove the dust plugs and make any optical connections, follow these guidelines:
Note 40-Gigabit QSFP+ or QSFP28 transceiver modules are keyed to prevent incorrect insertion.
Note The multiple-fiber push-on (MPO) connectors on the optical QSFP+ or QSFP28 transceivers support network interface cables with either physical contact (PC) or ultra-physical contact (UPC) flat polished face types. The MPO connectors on the optical QSFP+ or QSFP28 transceivers do not support network interface cables with an angle-polished contact (APC) face type.
Procedure
Step 1 Remove the dust plugs from the optical network interface cable MPO connectors. Save the dust plugs for future use.
Step 2 Inspect and clean the MPO connector's fiber-optic end faces.
Step 3 Remove the dust plugs from the QSFP+ or QSFP28 transceiver module optical bores.
Step 4 Immediately attach the network interface cable MPO connectors to the QSFP+ or QSFP28 transceiver module (see the figure below).

Figure 15: Removing the 40-Gigabit QSFP+ or 100-Gigabit QSFP28 Transceiver Module
Step 4 Place the QSFP+ or QSFP28 transceiver module into an antistatic bag.
You can connect optical interface ports on line cards with other devices for network connectivity.
Depending on the line card model that you are using, you can use either QSFP+ or QSFP28 transceivers. Some transceivers work with fiber-optic cables that you attach to the transceivers and other transceivers work with pre-attached copper cables. When installing fiber-optic cables for a port, you must install SFP transceivers for 1-Gigabit optical ports or install SFP+ transceivers for 10-Gigabit optical ports or QSFP+ transceivers for 100-Gigabit ports before installing the fiber-optic cable in the transceivers.
Removing and installing a transceiver can shorten its useful life. Do not remove and insert transceivers any more than is absolutely necessary. We recommended that you disconnect cables before installing or removing transceivers to prevent damage to the cable or transceiver.
When you need to remove fiber-optic transceivers, you must first remove the fiber-optic cables from the transceiver before you remove the transceiver from the port.
Depending on the router, the GNSS LED is located on the front or the rear side of the router.
Procedure
Step 1 Connect one end of a shielded coaxial cable to the GNSS RF IN port.
Step 2 Connect the other end of the shielded coaxial cable to the GNSS antenna after the primary protector.
Note The GNSS RF In port should have a primary protector installed to meet the Local Safety guidelines.
The GNSS RF In coaxial cable shield must be connected to the Facility Equipment Ground through the chassis. The chassis must have the ground wire connected to the Facility Equipment Ground.
GPS Port Pinouts
The platform is capable of receiving or sourcing GPS signals of 1 PPS & 10 MHz. These interfaces are provided by two mini-coax 50-Ohm, 1.0/2.3 DIN series connector on the front panel. Similarly there are two mini-coax 50-Ohm connectors provided in the front panel to output this 1PPS and 10MHz.
The table below summarizes the GPS port pinouts.
