GNSS Module (NCS4216-CM-GNSS)
The GNSS module is present on the RSP. It is a pluggable module that allows direct interface with the external antenna.
Note |
Using a single GPS antenna input for both RSPs requires usage of external splitters. |
Warning |
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023 |
Note |
The GNSS module is not hot swappable. |
GNSS Module RF Input Requirements
- The GNSS module requires an
active GPS/GNSS antenna with built-in Low-Noise Amplifier (LNA) for optimal
performance. The antenna LNA amplifies the received satellite signals for two
purposes:
- Compensation of losses on the cable
- Lifting the signal amplitude in the suitable range for the receiver frontend
The Amplification required is 22dB gain + cable/connector loss + Splitter signal loss.
The recommended range of LNA gain (LNA gain minus all cable and connector losses) at the connector of the receiver module is 22dB to 30dB with a minimum of 20dB and a maximum of 35dB.
- GNSS module provides 5V to the active antenna through the same RF input.
- Surge requirement:
GNSS modules have built-in ESD protections on all pins, including the RF-input pin. However, additional surge protection may be required if rooftop antennas are being connected, to meet the regulations and standards for lightning protection in the countries where the end-product is installed.
A lightning protection must be mounted at the place where the antenna cable enters the building. The primary lightning protection must be capable of conducting all potentially dangerous electrical energy to PE (Protective Earth).
Surge arrestors should support DC-pass and suitable for the GPS frequency range (1.575GHz) with low attenuation.
- Antenna Sky visibility:
GPS signals can only be received on a direct line of sight between antenna and satellite. The antenna should see as much as possible from the total sky. For proper timing, minimum of four satellites should be locked.
Note |
The antenna terminal should be earthed at the building entrance in accordance with the ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable. |
Power Supply Features
The Cisco NCS 4216 supports DC power supplies. The DC power supplies support:
- -40 VDC to -72 VDC
The power supplies are hot-swappable. They are enclosed to prevent exposure to high voltages, and therefore, no power cable interlock is required. However, the power supplies are automatically shut down when removed from the chassis. The power supplies are rated to deliver 900W (~75A at +12VDC) to the other FRUs in the system. The DC power supply has dual input feeds.
The following table shows the DC power supply specifications.

Note |
For normal operation, only one power feed is sufficient but an alarm is generated if only one power feed is present. You can suppress this alarm using the alarm profile configuration. |
For more information about installing the Cisco NCS 4216 power supplies, see the Installing the Power Supply .
Redundancy
Three power supplies can be plugged in the NCS 4216 chassis that works in the 2+1 redundancy mode. For the normal operation of the chassis, at least two power supplies should be powered on. When all the three power supplies are plugged in, they work in a current sharing mode.
Each power supply has dual feed. It is recommended to connect each power feed to a separate input source.
Dying Gasp
The Cisco NCS 4216 DC power supply does not support the Dying Gasp feature.
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 4216, see Troubleshooting section.
The DC Power Supply Specifications table summarizes the input power specifications for the Cisco NCS 4216 DC power supply units.

RSP Redundancy
The Cisco NCS 4216 chassis includes two RSP slots to allow for redundant RSPs. When the router 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.
Note |
Interface Module Slot support will vary based on Interface Modules used in other slots. For more information, refer the Configuration Guides for details. |
Network Timing Interfaces
The RSP supports the following network timing interfaces:
-
BITS input/output port—RJ48 jack
-
Wire Wrap Interface Through an Adapter
-
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.

The single port 100 Gigabit Ethernet interface module supports100 Gigabit Ethernet port. The figure above shows the interface module.
For more information about installing a 1X100GE module, see the Interface Module Installation section.
2-Port 100 Gigabit Ethernet Interface Module (2X100GE)
The 2-port 100 Gigabit Ethernet Interface Module (NCS4200-2H-PQ) design supports only one 100G QSFP28 optics on Port 0. Port 1 is disabled with RSP3. It currently supports only one mode of operation with 100Gbps of traffic with RSP3.
For more information about installing a 1X100GE module, see the Interface Module Installation section.
Limitations
After any QSFP28 100G optics is inserted, it approximately takes around 10 seconds for the optics to be detected and link to come up. The optics requires this time delay to be complete the initiation and operation.

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. |
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.
