Note
Port Connection Guidelines
Depending on the chassis and installed line cards, you can use Quad Small Form-Factor Pluggable Plus
(QSFP+), QSFP28, SFP, SFP+, and RJ-45 connectors to connect the ports on the line cards to other network
devices.
To prevent damage to the fiber-optic cables, we recommend 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:
Install the Device
12
Install the Device
Activate a DC Power Supply Module

•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 for 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.
Connect to the Console Port
• 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.
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.
Only RJ45 to DB-9 adapter cable is provided in the package.

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.
Figure 18: Console Port
To comply with GR-1089-CORE, the intra-building port(s) of the equipment must use shielded intra-building
cabling or wiring that is grounded at both ends.
Note
1. Plug the cable directly into the RJ-45 receptacle.
2. Connect the network end of your RJ-45 cable to a switch, hub, repeater, or other external equipment.

Figure 20: 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.
Caution
We strongly recommended that you do not install or remove the SFP or 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 or SFP+ module. Removing and
inserting a module can shorten its useful life; so you should not remove and insert modules more than it is
absolutely necessary.
Caution
When installing an SFP or SFP+ module, you would hear a click as the triangular pin on the bottom of the
module snaps into position 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 or SFP+ module.
