The Cisco NCS 4216 is a seven-rack unit router that belongs to the Cisco NCS 4200 family of routers. This router complements Cisco’s offerings for IP RAN solutions for the GSM, UMTS, LTE, and CDMA. Given its form-factor, interface types and GigabitEthernet density the Cisco NCS 4216 can also be positioned as a Carrier Ethernet aggregation platform.
The Cisco NCS 4216 is a cost optimized, fully redundant, centralized forwarding, extended temperature, and flexible pre-aggregation router.
The key feature of the Cisco NCS 4216 is to increase per platform and rack-unit interface density, especially when combining multiple interface types such as Gigabit Ethernet (GE), TDM, 10GE, 40GE and 100GE.
The Cisco NCS 4216 has the following hardware features:

The following table summarizes the system specifications and environmental requirements for the Cisco NCS 4216.
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. |
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 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 cal energy to PE (Protective Earth).
Surge arrestors should support DC-pass and suitable for the GPS frequency range (1.575GHz) with low attenuation.
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 cal Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable. |

The Cisco NCS 4216 supports DC power supplies. The DC power supplies support:
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.

For more information about installing the Cisco NCS 4216 power supplies, see the Installing the Power Supply.
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.
The Cisco NCS 4216 DC power supply does not support the Dying Gasp feature.
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.
DC Power Supply Specifications table summarizes the input power specifications for the Cisco NCS 4216 DC power supply units.
The fan tray modules supported on the router is:
The NCS4216 Fan tray uses
The fan tray has the following hardware features:
For more information about air flow guidelines, see Air Flow Guidelines section. For instructions on how to install the fan tray, see Installing the Fan Tray section. For a summary of the LEDs on the fan tray, see LED Summary section.
The dust filter on the fan tray is a quadrafoam 45PPI filter which is 85 percent dust resistant. For installing the fan filter, see Removing and Replacing the Dust Filter section.
Air Plenum or air baffle assembly is used change the air flow pattern of the unit. When the router 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 Air Plenum (A907-F2B-AIR) in the Rack section.
Note | When the air plenum and the fan filter are installed in the chassis, the system operating temperature is 55º C. |
The door provides access to the shelf, and acts as a protective panel.
The front door of NCS 4216 provides access to the shelf, and fan-tray assembly.
The front door acts as protective panels. The laser warning label is placed on the rear of the chassis.
The following figure illustrates the door design showing the front and back of the door.
The Cisco NCS 4216 is designed to use up to two RSP modules to handle the data plane, network timing, and control plane functionalities for the router. The RSP configuration allows you to use Cisco IOS software to control chassis management, redundancy, external management, and system status indications on the router.
The following sections describe the Cisco NCS 4216 RSP:
RSP features include:
Effective Cisco IOS-XE Release 3.18.06v.S, the Cisco NCS 4216 supports the following RSP:
The RSP does not provide external network interfaces for user traffic. All network interfaces are provided through separate IMs.
The RSP provides the following features on the Cisco router:
The following Ethernet interface modules support swapping on the Cisco NCS4216-RSP module.
Use the hw-module subslot default command before performing a swap of the modules. to default the interfaces on the interface module.

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. |
The RSP supports the following network timing interfaces:
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.
