This chapter describes how to install the various components in the Cisco NCS 560-4 Router and includes the following sections:
Prerequisites
Before installing the Cisco NCS 560-4 Router, it is important to prepare for the installation by:
Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOP). For more information,
see the Preparing for Installation section.
Unpacking and inspecting the Cisco NCS 560-4 Router
Gathering the tools and test equipment required to properly install the Cisco NCS 560-4 Router
Installing the Router in a Rack
The following sections describe how to install the Cisco NCS 560-4 Router in a rack:
The chassis is shipped with mounting brackets that can be installed on the front of the chassis. To install the brackets:
Note
Mounting brackets are not required if the router is mounted on a 19-inch EIA rack.
Procedure
Step 1
Remove the rack-mount brackets from the accessory kit and position them beside the router chassis.
Step 2
Position one of the brackets against the chassis side and align the screw holes.
Step 3
Secure the bracket to the chassis with the screws removed when performing Step 1. The recommended maximum torque is 6.2 in.-lb
(0.7 N-m).
The following figures shows how to attach the brackets on the Cisco NCS 560-4 Router for a ETSI rack and a 23-inch EIA rack.
Figure 1. Installing the Mounting Brackets for n ETSI Rack
Figure 2. Installing the Mounting Brackets for the 23-inch EIA Rack
Step 4
Position the chassis in the rack as follows:
If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between the mounting
posts.
If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting posts.
Step 5
Align the mounting holes in the bracket with the mounting holes in the equipment rack.
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can
deform or damage the handles.
Figure 3. Mounting the Router on a 19-inch EIA Rack
Note
The router can be mounted in an ETSI rack but the required bend radius for the cables and fibers within the 300 mm ETSI specification
cannot be maintained.
If you want to mount the router in ETSI cabinets, you need to have a custom-made cabinet front door to meet the fiber bend
radius requirement.
Step 6
Install the 8 or 12 (4 or 6 per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the holes in the bracket and into
the threaded holes in the equipment rack posts.
Step 7
Use a tape measure and level to verify that the chassis is installed straight and level.
Assembling the Plenum (N560-4-F2B-AIR-U=)
The plenum allows the air around the router to be distributed evenly.
Note
If a plenum is to be installed on the rack, ensure that it is first assembled before it is mounted on the rack.
Note
Installing the chassis in a plenum changes the air flow direction from right-to-left of router to front-to-back of the router.
Procedure
Step 1
Refer to the figures below to assemble the plenum. Secure all screws using a torque of 11.5 in.-lb (1.3 N-m).

Installing the Power Supply
The Cisco NCS 560-4 Router router provides the choice of three different power supplies—two DC power supplies and one AC
power supply:
1200 W DC power (N560-PWR1200-D-E and A900-PWR1200-D): - 40.8VDC to -72VDC
The A900-PWR1200-D DC power supply uses 3 position terminal block-style connector with positive latching/securing and labeled
connections for RTN and 48V.
The N560-PWR1200-D-E DC power supply uses 2 position terminal block-style connector with positive latching/securing and labeled
connections for RTN and 48V.
The terminal block connector is of suitable size to carry the appropriate AWG wire size (6AWG to 14 AWG) to handle the input
current of the power supply. No ON/OFF switch is provided.
AC power (A900-PWR1200-A): 85VAC to 264VAC
The AC power supply has an IEC-320-C21-type power receptacle and a 20 A service connector. You can use standard right-angle
power cords with the AC power supply. The power supply includes a power cord retainer. No ON/OFF switch is provided.
Caution
Unseat the power supply partially so that there is enough space to open the terminal block cover. Ensure the branch circuit
breaker is turned off. Only after installing the power supply in the chassis, should the branch circuit breaker be turned
on. The branch circuit breaker must be turned off before unplugging the power supply.
Each power supply provides a single primary input power connection. The router supports (2+1) redundancy.
Warning
Read the installation instructions before connecting the system to the power source. Statement 10
Note
Products that have an AC power connection are required to have an external surge protective device (SPD) provided as part
of the building installation to comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety.
Caution
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can
deform or damage the handles.
Preventing Power Loss
Use the following guidelines to prevent power loss to the router.
To prevent loss of input power, ensure that the total maximum load on each circuit supplying the power supplies is within
the current ratings of the wiring and breakers.
In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant
technology. These UPS types can become unstable with systems like the Cisco NCS 560-4 Router, which can have substantial current
draw fluctuations due to bursty data traffic patterns.
Use the information in the DC Power Supply Specifications table to estimate the power requirements and heat dissipation of
a Cisco NCS560-4 Router based on a given configuration of the router. Determining power requirements is useful for planning
the power distribution system needed to support the router.
Power Connection Guidelines
This section provides guidelines for connecting the Cisco NCS 560-4 Router power supplies to the site power source.
Warning
Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate
electrical inspection authority or an electrician if you are uncertain that
suitable grounding is available. Statement 213
Warning
The plug-socket combination must be accessible at all times because
it serves as the main disconnecting device. Statement 1019
Note
The above statement is applicable only to the AC power supplies.
Warning
This product requires short-circuit (overcurrent) protection, to be
provided as part of the building installation. Install only in accordance with
national and local wiring regulations. Statement 1045
Guidelines for DC-Powered Systems
Basic guidelines for DC-powered systems include the following:
Each chassis power supply should have its own dedicated input power source. The source must comply with the safety extra-low
voltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, and IEC 60950 standards.
The circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should be sized according to the
power supply input rating and local or national code requirements.
The circuit breaker is considered the disconnect device and should be easily accessible.
The system ground is the power supply and chassis ground.
Do not connect the DC return wire to the system frame or to the system grounding equipment.
Use the grounding lug to attach a wrist strap for ESD protection during servicing.
Guidelines for AC-Powered Systems
Basic guidelines for AC-powered systems include the following:
Each chassis power supply should have its own dedicated branch circuit.
The circuit breaker should be sized according to the power supply input rating and local or national code requirements.
The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to
the receptacles should connect to protective earth ground at the service equipment.

This section describes the installation and removal of the RSP.
Installing an RSP Module
To install an RSP module in the router chassis, perform the following steps:
Procedure
Step 1
Slip on the ESD-preventive wrist strap that was included in the accessory kit.
Step 2
Choose a slot for the module. Make sure that there is enough clearance to accommodate any equipment that will be connected
to the ports on the module. If a blank module filler plate is installed in the slot in which you plan to install the module,
remove the plate by removing its 2 Phillips pan-head screws.
Step 3
Fully open both the ejector levers on the new module.
Caution
To prevent ESD damage, handle modules by carrier edges only.
Step 4
Position the module in the slot. Make sure that you align the sides of the module with the guides on each side of the slot,
as shown in the figure below.
Figure 25. RSP Installation
Step 5
Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module in the adjacent
slot and both the ejector levers have closed to approximately 45 degrees with respect to the module faceplate.
Caution
If the top slot already has an RSP module installed, and you install a second RSP module in the slot below it, be careful
not to damage the EMI gasket of the bottom RSP module against the ejector levers of the top RSP during insertion.
Step 6
While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane connector. The
ejector levers are fully closed when they are flush with the module faceplate.
Step 7
Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5 in.-lb (.62 N-m).
Note
Make sure that the ejector levers are fully closed before tightening the captive installation screws.
Step 8
Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step ensures
that the EMI gaskets on all the modules are fully compressed in order to maximize the opening space for the new or replacement
module.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward
the open slot, which reduces the size of the opening and makes it difficult to install the new module.
Caution
Blank module filler plates (Cisco part number N560-4-RSP-BLANK) should be installed in any empty chassis slots to keep dust
out of the chassis and to maintain consistent airflow through the chassis.
Note
When installing the cabling to an RSP, we recommend that you leave a service loop of extra cabling sufficient to allow for
fan tray removal.
Note
Close all unused RJ-45 and USB ports on the RSP module using the appropriate dust caps to prevent dust from accumulating
inside the cage. For information on dust caps, see the Installing Dust Caps section.
Removing an RSP Module
Before you remove an RSP from the router, you should save the current configuration on a TFTP server or an external USB flash
drive, using the copyrunning-config {ftp| tftp| harddisk:} command. This saves you time when bringing the module back online.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement
1034
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly
with optical instruments. Statement 1051
To remove an RSP module:
Before you begin
See the table below for the OIR parameters for RSPs.
Table 5. Online Insertion and Removal - Parameters
5 It is not recommended to perform OIR of any module above 40°C ambient
Procedure
Step 1
Slip on the ESD-preventive wrist strap that was included in the accessory kit.
Step 2
Disconnect any cables attached to the ports on the module.
Step 3
Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures that the space
created by the removed module is maintained.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open
slot, which in turn reduces the size of the opening and makes it difficult to remove the module.
Step 4
Loosen the two captive installation screws on the module you plan to remove from the chassis.
Step 5
Place your thumbs on the ejector levers (see ) and simultaneously rotate the ejector levers outward to unseat the module
from the backplane connector.
Step 6
Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place
your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.
Caution
To prevent ESD damage, handle modules by the carrier edges only.
Step 7
Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.
Step 8
Install blank module filler plates (Cisco part number N560-4-RSP-BLANK) in empty slots, if any.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents
inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the
flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers
are in place. Statement 1029
Removing the IM Center Brackets
The IM center brackets are already installed in the chassis. They allow for installing two interface modules of half-width
side-by-side. By removing the IM center bracket, full-width Interface Modules with higher capacity and interface density can
be installed in the chassis.
Procedure
Step 1
Slip on the ESD-preventive wrist strap that was included in the accessory kit.
Step 2
Grasp the IM center bracket from its sides and slide it straight out of its slot.
Figure 26. Removing the IM Center Bracket from the IM Slot
This completes the removal of the IM center brackets.
Interface Module Installation
The following sections describe the various tasks associated with interface module installation on the Cisco NCS 560-4 Router:
Installing an Interface Module
Procedure
Step 1
Slip on the ESD-preventive wrist strap that was included in the accessory kit.
Step 2
Before inserting an interface module (IM), make sure that the chassis is grounded.
Step 3
To insert the IM, carefully align the edges of the IM between the upper and lower edges of the IM slot.
Step 4
Carefully slide the IM into the slot until the IM makes contact with the backplane.
Figure 27. Inserting an Interface Module
Step 5
Tighten the locking thumbscrews on both sides of the interface module. The recommended maximum torque is 5.5 in.-lb (.62 N-m).
Step 6
Connect all the cables to each interface module when ready for test and turn-up.
Caution
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can
deform or damage the handles
Note
Close all unused RJ-45, SFP, XFP, and QSFP ports on the interface module using the appropriate dust caps to prevent dust from
accumulating inside the cage. For information on dust caps, see Installing Dust Caps .
Removing an Interface Module
Procedure
Step 1
Slip on the ESD-preventive wrist strap that was included in the accessory kit.
Step 2
To remove an interface module, disconnect all the cables from each interface module.
Step 3
Loosen the locking thumbscrews on both sides of the interface module.
Step 4
Slide the interface module out of the IM slot by pulling on the handles. If you are removing a blank filler plate, pull the
blank filler plate completely out of the IM slot using the captive screws.
Hot-Swapping an RSP or Interface Module
The Cisco NCS 560-4 Router provides a feature that allows you to remove and replace a redundant RSP module without powering
down the router. This feature, called hot-swapping or OIR, allows you to remove and replace a redundant module without disrupting
router operation.
When two redundant modules are installed in the router, only one of the modules is active. The other one runs in standby mode,
ready to take over processing if the active module fails.
When you remove or insert a redundant module while the router is powered on and running, the router does the following:
Determines if there is sufficient power for the module.
Scans the backplane for configuration changes.
Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively
shutdown state.
Places any previously configured interfaces on the module back to the state they were in when they were removed. Any newly
inserted interfaces are put in the administratively shutdown state as if they were present (but unconfigured) at boot time.
If you insert the same type of module into a slot, its ports are configured and brought online up to the port count of the
original module.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
If the tests pass, the router is operating normally.
If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a problem in the
bus and should be removed.
Use the following guidelines when performing an OIR on an IM:
Allow at least two minutes for the system to reinitialize before inserting a new IM.
Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.
When inserting multiple IMs into the chassis, wait until each IM reaches an OK state before inserting the next IM.
Installing Dust Caps
The following list provides the product IDs (PIDs) for the dust caps that are available for each port type:
RJ-45—A900-DCAP-RJ45-S= (24 dust caps per package) or A900-DCAP-RJ45-L= (240 caps per package)
SFP—A900-DCAP-SFP-S= (24 caps per package) or A900-DCAP-SFP-L= (240 caps per package)
USB—A900-DCAP-USB-S= (12 dust caps per package) or A900-DCAP-USB-L= (120 dust caps per package)
XFP/QSFP—A900-DCAP-XFP-S= (12 dust caps per package) or A900-DCAP-XFP-L= (120 dust caps per package)
To install the dust cap:
Hold the dust cap by its handle.
Insert the dust cap in to the appropriate unused ports (RJ-45, SFP, USB, or XFP/QSFP) on the chassis front panel.

Step 4
Make sure that your modem and the router auxiliary port are configured for the same transmission speed (up to 115200 bps
is supported) and for mode control with data carrier detect (DCD) and data terminal ready (DTR) operations.
Connecting a Management Ethernet Cable
When using the Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X
mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automatically
senses a crossover or straight-through cable and adapts to it.
However, when the Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line interface
(CLI) commands, the port is forced to MDI mode.
When in a fixed-speed configuration and MDI mode:
Use a crossover cable to connect to an MDI port
Use a straight-through cable to connect to an MDI-X port
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Management Ethernet
ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be
grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces
that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors
is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Installing and Removing SFP Modules
The Cisco NCS 560-4 Router supports a variety of SFP modules, including optical and Ethernet modules. For information on
how to install and remove SFP modules, see the documentation for the SFP module at
We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module. This time is recommended
to allow the transceiver software to initialize and synchronize with the standby RSP. Changing an SFP more quickly could result
in transceiver initialization issues that disable the SFP.
Connecting a USB Flash Device
To connect a USB flash device to the Cisco NCS 560-4 Router, insert the memory stick in the USB port labeled MEM. The Flash
memory module can be inserted in only one way, and can be inserted or removed regardless of whether the router is powered
up or not.
Removing a USB Flash Device
To remove and then replace a USB flash token memory stick from a Cisco NCS 560-4 Router, follow these steps:
Procedure
Step 1
Pull the memory stick from the USB port.
Step 2
To replace a Cisco USB Flash memory stick, simply insert the module into the USB port labeled USB MEM. The Flash memory module
can be inserted in only one way, and can be inserted or removed regardless of whether the router is powered up or not.
Note
You can insert or remove the memory stick whether the router is powered on or not.
This completes the USB Flash memory installation procedure.
Connecting Timing Cables
The following sections describe how to connect timing cables to the Cisco NCS 560-4 Router:

Connecting Cables to the BITS Interface
The following steps describe how to connect a cable to the router BITS port:
Procedure
Step 1
Confirm that the router is powered off.
Step 2
Connect one end of the cable to the BITS port using a straight-through, shielded RJ48C-to-RJ48C cable.
Step 3
Connect the other end to the BTS patch or demarcation panel at your site.
Step 4
Turn on power to the router.
For information about the BITS port pinouts, see Troubleshooting.
Note
Use of two BITS sources or a Y-cable is optional. Each BITS input port is routed to both RSPs, so that SETS device on each
RSP has visibility to both BITS inputs.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the BITS ports only
to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at
both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that
connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type
4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors
is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the ToD ports only
to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at
both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that
connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type
4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors
is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Note
For more information about GPS port pinouts, see the LED Details section.
Connecting Cables to a GNSS Interface
The following sections describe how to connect cables from the Cisco NCS 560-4 Router to a GPS unit for input or output timing
of frequency.
Note
A Y-cable is required to connect to a primary and backup RSP in order to ensure that the router continues to transmit timing
signals in the event of a network failure. For a mini-coax connection, this Y-cable can be part number CAB-BNC-7INY (7 inch
BNC Y-cable). For an Ethernet connection, this Y-cable can be a RJ45 Cat5 1-to-2 splitter (3 female port RJ45 connector).
Note
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient to allow
for fan tray removal.
Connecting a Cable to the GNSS Antenna Interface

see Connecting Cables to SFP Modules.
The RJ45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables. Cisco Systems
does not supply Category 5 UTP cables; these cables are available commercially.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Gigabit Ethernet
ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be
grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces
that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors
is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Note
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient to allow
for fan tray removal.
Follow these steps to connect the cable to a copper Gigabit Ethernet port:
Procedure
Step 1
Confirm that the router is powered off.
Step 2
Connect one end of the cable to the Gigabit Ethernet port on the router.
Step 3
Connect the other end to the BTS patch or demarcation panel at your site.
Connecting Cables to SFP Modules
For information on connecting cables to Cisco optical and Ethernet SFP interfaces, see
The Cisco NCS 560-4 Router supports a variety of SFP modules, including optical and Ethernet modules. For information on
how to install and remove SFP modules, see the documentation for the SFP module at
We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module. This time is recommended
to allow the transceiver software to initialize and synchronize with the standby RSP. Changing an SFP more quickly could result
in transceiver initialization issues that disable the SFP.
