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.
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 Cisco NCS 540 fixed-port chassis. The console cable is shipped with the hardware.
