N560-RSP4 route processor is a medium-scale route processor with 800 Gbps throughput, maximum 700MPPS packet processing rate,
and wide form factor.
N560-RSP4-E route processor is a large-scale route processor with 800 Gbps throughput, maximum 700MPPS packet processing rate,
and wide form factor.
For more information on N560-RSP4 and N560-RSP4-E route processors, see Product specifications.
The N560-RSP4 and N560-RSP4-E route processors (RSPs) increase the system capacity, interface density and scale of the routers
they are installed in. These RSPs operate on the 64-bit IOS-XR (eXR) operating system and are designed to support 1:1 redundancy
for the data plane. Both RSPs receive and forward traffic; however, only the active data plane forwards traffic to the external
network.
The N560-RSP4 and N560-RSP4-E are supported on the Cisco ASR 907 Routers (which effectively turns the Cisco ASR-907 Router
into an NCS560-7 Router, running the Cisco IOS-XR software) and can be installed in any available route processor slot in
these chassis.
Note
Do not use the N560-RSP4 and N560-RSP4-E route processors together in the same router.
RSP Redundancy
When two RSPs are installed in a router, one RSP is the active RSP and the other is a backup, or standby, RSP. If the active
RSP fails or is removed from the system, the standby RSP detects the failure and initiates a switchover. During a switchover,
the standby RSP assumes control of the router, connects with the network interfaces, and activates the local network management
interface and system console.
Note
If your system includes redundant RSPs, both RSPs should be of the same type and have the same memory size. We strongly recommend
that you avoid configuring your router using mixed route processor cards.
External Interfaces
Network Interfaces
The N560-RSP4 and N560-RSP4-E modules support the following network interfaces through the pluggable IMs:
GE SFP ports – supporting 1000/1GE modes with A900-IMA-8CS1Z-M
GE C-SFP ports – supporting 1000/1GE BASE-BX modes with A900-IMA-8CS1Z-M
10GE SFP+ ports – supporting 10GE mode with A900-IMA-8CS1Z-M, A900-IMA-8Z, and A900-IMA-8Z-L IMs
100GE QSFP-28/QSFP-DD 100G ZF1/QSFP+ Ethernet ports using 2 x 100GE IM – supporting both 100GE and 40GE with N560-IMA-2C.
Effective Cisco IOS XR Release 7.3.2, only 100GE is supported on the N560-IMA-2C-DD. Effective Cisco IOS XR Release 7.8.1 Quad Small Form-Factor Pluggable Double Density (QSFP-DD 100G ZF1) is supported on the interface module. Only 100GE is supported
in a single fixed wavelength mode.
Network Timing Interfaces
The following network timing interfaces are located on the RSP:
BITS simultaneous input and output (T1/E1)—RJ48 jack
1PPS input—mini-coaxial connector
1PPS output—mini-coaxial connector
2.048/10MHz input—mini-coacoaxialx connector
2.048/10MHz output—mini-coax connector
ToD input or output—shielded RJ45 jack
GNSS RF input port—To support high availability, an RSP GPS support with single antenna, external passive splitter is required
to split output while maintaining the minimum RF power input required by GNSS receiver.
The network interfaces are sources and destinations of frequency (for example, SyncE, T1/E1, SONET/SDH) and phase/ToD (for
example, IEEE 1588-2008 PTP).
Management Interfaces
Copper 10/100/1000Base-T LAN management port—RJ45 jack
Console/Aux RS232 serial ports—RJ45 jacks
Console—USB 2.0 type A receptacle
Mass Storage—USB 2.0 or 3.0 type A receptacle
Indicators
Status LEDs are present on the RSP. For more information on LED, see LED Details.
Licensing
The Cisco NCS 560 router with RSP4/RSP4-E utilizes Cisco’s IOS-XR Software Flexible Consumption Licensing Model. For information
on the IOS-XR Flexible Consumption License, see:
For the NCS 560 with RSP4 RSP4-E, the Flexible Consumption Model comprises two software suites:
The Essentials software suite is required for active ports in the system and is a per-100-Gbps capacity license.
The Advanced software suite is required when one or more of the Advanced software suite features are used (for example, L2VPN,
L3VPN, and E-VPN Services), and is on a per-100-Gbps capacity license.
The Essentials software suite supports the following features on a per-100-Gbps capacity license:
Starting with Cisco IOS XR Release 7.5.1, 1G mode is supported on A900-IMA8Z-L IM. Use the following command to configure A900-IMA8Z-L interface module in 1G mode:
hw-module quad1slot0mode1g
The A900-IMA-8CS1Z-M interface module is supported on 0-15 slots of the chassis. Out of the nine physical ports, the first
eight are CSFP ports, thus a total of 17 ports are present in the interface module. Out of these 17 ports of the interface
module, ports 0-15 are 1G CSFP ports and port 16 is 10G SFP+ port. However, for slots 0, 1, 14, and 15, you can only use the
even ports of the interface module. This is because the odd ports are unusable due to bandwidth restrictions.
Starting with Cisco IOS XR Release 7.4.2, the A900-IMA-8CS1Z-IM interface module is supported on slots 0, 1, 14, and 15 in 8 x 1G and 1 x 10 mode by disabling the
odd 1G ports. You can achieve this by using the following command to disable the eight unused odd ports (1, 3, 5, 7, 9, 11,
and 15) within the slots:
hw-module slot <0-15 >im-mode1
Out of the nine even ports of the interface module, ports 0, 2, 4, 6, 8, 10, 12, and 14 can be used as 1G ports and port 16
can be used as 10G port. Disabling the odd ports of the interface module helps increase the router's port density by optimizing
hardware resource utilization.

Fan Tray (FAN-H)
FAN-H enhances the thermal performance of the chassis. It supports industrial temperature ambient condition with industrial
temperature optics in the chassis.
For information about the installation of the fan tray, see the Installing the Fan Tray section.
Fan Tray (A907-FAN-E)
The A907-FAN-E has:
Four dual rotor fans—for the PSU area cooling
12 fans (three columns for four fans)—60x60x38mm fans for the RSP and interface modules
This fan tray has redundant fans and provides side-to-side forced air cooling. A907-FAN-E is a field replaceable unit (FRU).
The following table describes the fan speed when used with the N560-RSP4 route processor.

Online Insertion and Removal
The Cisco routers, interface modules, and FAN-H are designed to support online insertion and removal (OIR). However, time-to-OIR
for FAN-H fan tray is dependent on the temperature of the chassis. At room temperature of up to 30° C, fan tray OIR should
be done within two minutes.
Note
Before replacing the card, you must perform a graceful shutdown of the card to avoid disk corruption.

8 Fan Tray OIR should be performed only when a fan's failed
condition is encountered and other fans are spinning at max
speed.
9 It is recommended to shut down the interface
modules before attempting to remove them from the
chassis.
Note
Consecutive IMs insertions, consecutive IMs reload or removal, and subsequent IM
re-oinsertion should be done while waiting at least 180s between the actions.
Power Supply Requirement
As the N560-RSP4 supports various interface modules, there are system configurations that require wattage higher than 1200W
to support the chassis power. In this case, (2+1) configuration is recommended for 1200W DC or 1200W AC power supply unit
(PSU), where the two PSUs are required for system operations and one PSU is redundant. In this case, all three PSUs are in
load sharing mode and the system continues to operate with one PSU failure. For more details on system power, see the CPC
tool or get in touch with your Cisco Sales contact.
