CHAPTER 1
Cisco ASR 907 Router Overview
The Cisco ASR 907 Router seven-rack unit router that belongs to the Cisco ASR90x 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 ASR 907 Router can also be positioned
as a Carrier Ethernet aggregation platform.
The Cisco ASR 907 Router is a cost optimized, fully redundant, centralized forwarding, extended temperature,
and flexible pre-aggregation router.
•Cisco ASR 907 Router Features, page 1
•Interface Numbering, page 15
•Regulatory Compliance, page 15
Cisco ASR 907 Router Features
The key feature of the Cisco ASR 907 Router 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 ASR 907 Router has the following hardware features:
•A larger service scale and higher throughput (400G) Route Switch Processors
(RSP)—A900-RSP3C-400-W
•One-port 100GE Interface Module (A900-IMA1C)
•Two-port 40GE Interface Module (A900-IMA2F)
•1200 Watt PSUs to power the new RSP modules
The Cisco ASR 907 Router includes the following specific components:
•Larger chassis —Seven rack unit in height while still maintaining a shallow depth and side-to-side air
flow.
•Larger fan-tray with removable dust filter.
•New form factor and higher performance RSP—This high performance RSP has aggregate switching
capacity of 480 Gbps in oversubscribed mode.
Cisco ASR 907 Router Hardware Installation Guide
1

•The backplane and the RSP together have the provision to support higher density 10GE modules like
8x10GE and 100GE modules.
•Air flow baffle to allow a system to redirect air and allow front-to-back airflow for cooling.
•Flexible I/O configurations through 16 hot pluggable interface modules (single width). For example,
with RSP3-400-W in oversubscribed mode:
◦16x10G + 2x100G + 80x1G
◦48x10G
•Metro ENET switching features along with TDM pseudo-wire support.
•Network processor provides flexibility to off-load control plane CPU processing for select OAM and
management packets (for example, CCM, BFD, LBM).
•Flexible ENET processing through table-driven packet processing engines.
•On-line insertion/removal (OIR) of all FRUs except GPS module, while the system is operational.
•Power supply (1+1)—Support for both, AC and DC power supplies. A single power supply can support
full system load. If there are two PSUs in the system, they work in a load-sharing mode.
•Fully-redundant system with redundant combined control plane and data plane (excluding interfaces),
timing support, power supplies, and fans.
•Active and standby support of redundant control plane and data plane, and timing
•Intra-chassis IOS redundancy (requires both RSPs)
•Stateful-switchover (50 ms) between active and standby RSPs (for protocols supported by IOS).
•In-service software upgrade (ISSU) supported with same RSPs.
•Timing support for receipt and distribution of network frequency and time including SyncE, BITS,
1PPS/10MHz I/O, IEEE 1588-2008, and NTP.
•Support for ENET OAM.
•T1/E1 line protection compliant with NEBS GR-1089.

GNSS Module (A900-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
Cisco ASR 907 Router Hardware Installation Guide

Cisco ASR 907 Router Overview
GNSS Module (A900-CM-GNSS)

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.
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
•Use a passive splitter if more than one GNSS modules are fed from a single antenna.
Power Supply Features
The Cisco ASR 907 Router supports two 1200W DC/AC power supplies in slot 0 and slot 1.
Slot 2 should be left unused; insert only the PSU blank in slot 2.Note
The AC and DC power supplies support:
•-40.8 VDC to -72 VDC
Cisco ASR 907 Router Hardware Installation Guide
6
Cisco ASR 907 Router Overview
Power Supply Features

•85 VAC to 264 VAC
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 1200W (~100A at +12VDC) to the other FRUs in
the system and are rated for operation at 5ºC above the chassis operating temperature.
See the below tables for the AC and DC power supply specifications.

Cisco ASR 907 Router Overview
Power Supply Features

Redundancy
The Cisco ASR 907 Router 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 AC and DC power supply. The Cisco ASR 907 Router supports current sharing
between the power supplies.
If you install a redundant power supply on the Cisco ASR 907 Router, we recommend that you connect each
power supply to a separate input power source in order to ensure that the router maintains power in the event
of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit breaker.
Dying Gasp
The Cisco ASR 907 Router 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 ASR 907 Router, see Troubleshooting.
Fan Tray
The fan tray modules supported on the router is:
•A907-FAN-E
The ASR907 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. For instructions on how to install
the fan tray, see Installing the Fan Tray. For a summary of the LEDs on the fan tray, see LED Summary.
Dust Filter (A907-FAN-F)
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.
