Power Supply Features
The Cisco NCS 4206 support DC power supplies. For more information about installing the Cisco NCS 4206 power supplies, see Installing the Power Supply.
To estimate the required power supply, use the Cisco Power Calculator.
The power sections provide more information about the power supply.
Redundancy
The Cisco NCS 4206 chassis includes a slot for an optional redundant power supply. The redundant power supply option provides a second power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails. Redundancy is supported either with identical power supplies or a combination of DC power supply. The Cisco NCS 4206 supports current sharing between the power supplies.
If you install a redundant power supply on the Cisco NCS 4206, we recommend that you connect each power supply to a separate input power source in order to ensure that the chassis maintains power in the event of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit breaker.
Status LEDs
LEDs are also provided on each power supply to indicate the status of the input power and the health of the power supply. For more information about the LEDs on the Cisco NCS 4206, see Troubleshooting.
DC Power Specifications
The power supply contains a front panel with mounting screws, a handle for insertion and removal, and two status LEDs. No ON/OFF switch is provided. The power supply is field replaceable and hot-swappable.
The DC power supply model supported on the chassis is:
- A900-PWR900-D2—Provides 900 W output power for system. See the figure below.
![](/c/dam/en/us/td/i/300001-400000/360001-370000/365001-366000/365662.eps/_jcr_content/renditions/365662.jpg)

Plenum
Plenum or air baffle assembly (see the figure below) is used to change the air flow pattern of the unit. When the chassis is installed with the plenum, the air flow pattern is changed from side-side to front-back. The air flow front-back pattern provides a rack installation bay with a cool front zone and hot rear zone. For installing the plenum, see Installing the Chassis in the Plenum.
![](/c/dam/en/us/td/i/300001-400000/360001-370000/365001-366000/365296.eps/_jcr_content/renditions/365296.jpg)
![]() Note |
When the plenum and air filter are installed in the chassis, the system operating temperature is 55 degrees Celsius. |
The air filter must be removed for cleaning or for a replacement.
Air Filter Maintenance
A periodic health check of the filter, every 3 months based on the level of dust in the environment helps in avoiding over clogging of the filters and provide better life. The filter may be used as a single use or reused depending upon the local deployment needs. If reuse of the filter is prohibited, it may be replaced every six months.
If reused, this filter media may be cleaned with slightly compressed air, vacuumed, and/or rinsed with clean water. If a degreaser is required, use only a mild detergent, such as, dish washing liquid.
![]() Caution |
Avoid using harsh solvents or cleaning agents. |
If filter is cleaned with water, the filter should be completely dry before reinstalling. Even though this type of filter may be cleaned, replacement is recommended every two to three years to ensure media durability and eliminate residual dust build-up and subsequent air flow resistance.
RSP Modules
The Cisco NCS 4206 is designed to use up to two RSP modules to handle the data plane, network timing, and control plane functionalities for the chassis. The RSP configuration allows you to use Cisco IOS software to control chassis management, redundancy, external management, and system status indications on the chassis.
RSP features include:
- Loading software onto processor-based interface modules
- Redundant RSP management—The RSP manages detection of RSPs, exchange of health and status information, role negotiation, function for detection, health and status exchange, role negotiation
- Packet processing
- Traffic management, including buffering, queuing, and scheduling, Ethernet MAC functions
- Network clocking functions including phase and time-of-day for BITS, 1 PPS, 10 MHz, and 1588 PTP clock references
- Storage of software images, system configuration, OBFL, SysLog
- PTP packet processing including IEEE 1588-2008 for recovering network timing (frequency, phase, and time) from upstream PTP clocks, for generating PTP frequency and phase references as inputs to the SETS, and for distributing them to downstream PTP clocks
- External management interfaces (RS232 console, management ENET, USB console, USB storage) and system status LED indicators

RSP Redundancy
The Cisco NCS 4206 chassis includes two RSP slots to allow for redundant RSPs. When the chassis uses redundant RSPs, one RSP operates in the active mode and the other operates in the hot standby mode. Removal or failure of the active RSP results in an automatic switchover to the standby RSP.
Network Timing Interfaces
The RSP supports the following network timing interfaces:
-
BITS input/output port—RJ48 jack
-
1 PPS input and output—Mini coax connectors
-
2.048 or 10 MHz input and output—Mini coax connectors
-
Time of Day (ToD) or input/output port and 1 PPS input port—Shielded RJ45 jack
Network timing interfaces support redundancy in a redundant RSP configuration. Network timing interfaces on a redundant RSP remain in operation while the RSP is in hot standby mode.

NCS 4200 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module (NCS4200-1T8S-20CS)
The NCS 4200 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module, iMSG is a cost-effective interface module (IM) that supports CEM and Multiservice Gateway features on the OCn interfaces.
![]() Note |
The Multiservice Gateway features are not supported on this IM on Cisco IOS XE Release 16.12.1. |
![](/c/dam/en/us/td/i/300001-400000/360001-370000/369001-370000/369677.jpg)
The NCS 4200 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module, iMSG IM supports eight SFP optical interfaces supporting at OC-3/OC-12/OC-48/1G rates and a single SFP+ optical interface supporting at OC-192/10G.
This IM operates in two modes:
-
20G mode; uses two XFI lanes towards the system
-
10G mode; uses single XFI lane towards the system
The benefits of this IM are:
-
Improves backplane efficiency
-
Increases system capacity
-
Increases client flexibility
The most important feature of the NCS 4200 1x10G MR + 8x20G LR CEM, iMSG IM is it provides more flexibility from the interface, which allows you to configure any interface speed on the OCn port irrespective of the IM bandwidth. The bandwidth restriction comes into effect only when the circuit is configured.
For example, you can configure the SFP+ port as an OC-192 and the other eight optical ports as OC-48 to have the total interface speed of 30G. However, if you configure only one STS-1 HO CEP on each port that will take only 9xSTS-1, which is equivalent to 500 Mbps (9 x 52Mbps x1.06) of the backplane traffic.
Restrictions
-
On the port capable of OC-192 speed, lower speed such as, OC-3, OC-12, or OC-48 are not supported.
-
No license is required to enable the Ethernet, OTN and Sonet/SDH functionalities.
-
The SFP port supports OC-3, OC-12, and OC-48. SFP+ port supports OC-192.

Temperature Sensor
The Cisco NCS 4206 has a temperature sensor to detect overtemperature conditions inside the chassis.
Temperature Sensors on the RSP modules
The maximum operating temperature of NCS420X-RSP module and the interface modules is less than the maximum operating temperature of the Cisco NCS 4206.
The IOS XE software decides the appropriate temperature thresholds to generate warnings, and shuts down the system when abnormally high temperature is detected.
Patch Panels
The Cisco router has patch panels modules that provide interconnections with the interface modules.
The following table shows different types of patch panel:
