CHAPTER 1
Cisco ASR 903 Router Overview
The Cisco ASR 903 Router is a fully-featured aggregation platform designed for the cost-effective delivery
of converged mobile and business services. With shallow depth, low power consumption, and an extended
temperature range, this compact 3-rack-unit (RU) router provides high service scale, full redundancy, and
flexible hardware configuration.
The Cisco ASR 903 Router expands the Cisco service provider product portfolio by providing a rich and
scalable feature set of Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package.
It also supports a variety of software features, including Carrier Ethernet features, Timing over Packet, and
pseudowire.
The Cisco ASR 903 Router is positioned as a pre-aggregation router in IP RAN (GSM, UMTS, iMAX,
CDMA, and LTE) networks or an aggregation router in Carrier Ethernet networks.
•Cisco ASR 903 Router Features, page 1
•Interface Numbering, page 49
•Regulatory Compliance, page 51
Cisco ASR 903 Router Features
The Cisco ASR 903 Router has the following hardware features:
•3-RU modular chassis designed for installation in a 300 mm European Telecommunications Standards
Institute (ETSI) cabinet
•Dedicated slots in the chassis that support the following:
◦Up to six interface modules
◦Up to two Route Switch Processors (RSP)
◦Up to two AC or DC power supply units
◦One fan tray
•Network frequency, phase, and time inputs and outputs for network interfaces (SyncE and TDM), BITS,
1 PPS or 10 MHz and Timing over Packet (IEEE 1588-2008)
•Adjustable front and rear rail mounting locations

•Front panel access to power supplies, fan tray, RSPs, and interface modules
•Online insertion and removal (OIR) of RSP, interface modules, power supplies, and fan tray
•Discrete status LEDs on power supply, interface module, RSP, and fan tray units
•Four alarm dry contact inputs (either normally open or normally closed)
•Environmental monitoring and reporting functions
•LED indicators for critical, major, and minor alarms
•Side-to-side forced air cooling
•Temperature range, see Cisco ASR 900 Series Aggregation Services Routers Data Sheet.

Power Supply Features
The Cisco ASR 903 Router support AC and DC power supplies. For more information about installing the
Cisco ASR 903 Router power supplies, see the Installing the Power Supply.
To estimate the required power supply, use the Cisco Power Calculator.

Cisco ASR 903 Router Overview
Power Supply Features

The power sections provide more information about the power supply:
Redundancy
The Cisco ASR 903 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 903 Router supports current sharing
between the power supplies.
A redundant power supply on the Cisco ASR 903 Router is recommended. Each power supply should be
connected to separate independent power sources 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.
To comply with IEC 61850-3 (voltage interruptions), redundant power supplies with separately derived
power feeds are required.
Caution
Dying Gasp
The Cisco ASR 903 Router DC power supply supports the Dying Gasp feature, which allows the router to
provide an input power loss notification to the RSP so that the RSP can send appropriate SNMP traps or OAM
messages and update log files on the router. With the DC power supply, the router supports a minimum input
power loss detection time of 2 milliseconds (DC) and continued operation of at least 6 milliseconds (DC)
after the notification.
Continued DC power supply operation may vary for voltages other than +24/-48V.Note
Dying Gasp is not supported on the ASR 900 RSP3 module for 1200W DC power supply.Note
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 903 Router, see Troubleshooting.
DC Power Specifications
The power supply is field replaceable, hot-swappable, and operates separately from the fan tray. 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 DC PSU models supported on the router are:
•A900-PWR550-D—Provides 550 W output power for system 12 V power. Uses a euro-style three-position
terminal block connector.
Cisco ASR 903 Aggregation Services Router Hardware Installation Guide

Cisco ASR 903 Router Overview
Power Supply Features

•A900-PWR550-D-E—Provides 550 W output power for system 12 V power. Uses a T-shaped connector.
The A900-PWR550-D and the A900-PWR550-E power supply can be used with the A900-RSP3C-400-S
RSP modules only if the power consumption is within 550 W. However, A900-PWR1200-D is
recommended.
Note
•A900-PWR1200-D—Provides 975 W output power for system 12 V power with the A903-FAN module.
As most of the system configurations using A900-RSP3C-400-S RSP modules require power exceeding
550 W, we recommend using the A900-PWR1200-D power supply with A900-RSP3C-400-S RSP
modules.
