Port Connection Guidelines
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:
- 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.
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.
Interfaces and Port Description
For location of ports on the routers, see Network Interfaces.
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 5700 chassis.
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.
- Network cabling should already be routed to the location of the installed router.
Procedure
Set your terminal to these operational values: 115200 bps, 8 data bits, no parity, 1 stop bits (115200 8N1).
Attach the terminal end of the cable to the interface port on the data terminal.
Attach the other end of the cable to the console port.
