Cisco NCS 4216 Overview
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.

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.
Using a single GPS antenna input for both RSPs requires usage of external splitters.Note
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023Warning
The GNSS module is not hot swappable.Note
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.
Cisco NCS 4216 Hardware Installation Guide
5
Cisco NCS 4216 Overview
GNSS Module (NCS4216-CM-GNSS)

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.
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.
Note
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.

Power Supply Features

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.
Fan Tray
The fan tray modules supported on the router is:
•ASR907-FAN-E
The NCS4216 Fan tray uses
•Four dual rotor fans—for the PSU area cooling
•12 fans (three columns for four fans)—60x60x38mm fans for the RSP and IM area
The fan tray has the following hardware features:
•It provides side-to-side forced air cooling
•It provides redundant fans
•It is field replaceable
•It contains status LEDs
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.
Dust Filter (A907-F2B-AIR)
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 (A9X7-F2B-AIR)
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.
When the air plenum and the fan filter are installed in the chassis, the system operating temperature is 55º
C.
