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 pro viding a rich and
scalable feature set of Lay er 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package .
It also supports a variety of software features, in cluding Carrier Ethernet fe atures, 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.

Dying Gasp

Chapter 1 Cisco ASR 903 Router Overview

• AC Power Specifications, page 1-5

The Cisco ASR 903 Router chassis includes a slot for an optional redundant power supply. The
redundant power supply option provides a second, identical power supply to ensure that power to the
chassis continues uninterrupted if one p ower supply fails or input power on one line fail s. The
Cisco ASR 903 Router supports current sharing between the power supplies.

If you install a redundant po wer supply on the Cisco ASR 903 Router, we recommend that you connect
each power supply to a separate input po wer source in or der to ensure that the router mai ntains po wer in
the event of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit
breaker.

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.

Note Continued DC power supply operation may vary for voltages other than +24/-48V.

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 Chapter 5,

“Troubleshooting.”

DC Power Specifications

The Cisco ASR 903 Router uses a +24/-48 Volts Direct Current (VDC) (-19 to -72 VDC supply
tolerance) power supply. The power supply provides 550 W output power for system 12 V power. The
power supply is field replaceable, hot-swappable, and operates separately from the fan tray.

The power supply uses a three-position terminal block-style connector with labeled connections for
ground, -24/48 V, and +24/48 V . The po wer 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 Cisco ASR 903 Router uses a modular fan tray that is separate from the power supply. The fan tray
contains twelve fans and provides sufficient capacity to maintain operation indefinitely in the event of
an individual fan failure.

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

• It contains an alarm port with four external alarm inputs

tray, see “LED Summary” section on page 5-7.

The Cisco ASR 903 Router 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, red undancy, external management, and system status
indications on the router.

The following sections describe the Cisco ASR 903 Router RSP:

• Supported RSP Features, page 1-7

• RSP Redundancy, page 1-7

• Network Timing Interfaces, page 1-8

• RSP Interfaces, page 1-8

RSP features include:

• Loading software onto processor-based interface modules

• Redundant RSP management—The RSP manages detection of RSPs, exchange of health and status

information, role negotiation, function for detection, health and status exchange, role negotiation

• Packet processing

OL-25178-04

Chapter 1 Cisco ASR 903 Router Overview

• Traffic management, including buffering, queuing, and scheduling, Ethernet MAC functions

• Network clocking functions including phase and time-of-day for BITS, 1 PPS, 10 MHz, and 1588

PTP clock references.

• Storage of software images, system configuration, OBFL, SysLog

• PTP packet processing including IEEE 1588-2008 for reco ver ing network t iming (frequenc y, phase,

and time) from upstream PTP clocks, for generating PTP frequency and phase references as inputs
to the SETS, and for distributing them to downstream PTP clocks

• External management interfaces (RS232 console, management ENET, USB console, USB storage)

and system status LED indicators

Supported RSPs

The Cisco ASR 903 Router supports the following RSPs:

• A900-RSP1A-55—Provides 2 GB of SDRAM, 5 Mb of TCAM memory, 3-Mb buffer table,

576-Mb forwarding memory, and 1,536-Mb packet buffer memory.

• A900-RSP1B-55—Provides 4 GB of SDRAM, 20 Mb of TCAM memory, 144-Mb buffer table,

1152-Mb forwarding memory, and 1,536-Mb packet buffer memory.

Cisco ASR 903 Router Features

Note The supported RSPs have different memory capacities, but they have the same interfaces and

functionality.

Supported RSP Features

The RSP provides the following features on the Cisco router:

• Centralized data plane, timing, and control plane functions for the system

• High-level control of interface modules

• Management functionalities for the router

• Control plane (host) CPU and associated memory in which IOS-XE and platform control software

runs

• Nonvolatile memory for storage of software images, configurations, and system files

• Enabling and monitoring the health and presence of fan trays, interface modules, and po wer supplies

• Field replacement and hot-swap capabilities

RSP Redundancy

The Cisco ASR 903 Router 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.

OL-25178-04

Note If you are using redundant RSPs, both the RSPs must be of the same type because a mixed conf iguration

of two different RSP types is not supported.

Cisco ASR 903 Router Hardware Installation Guide

Cisco ASR 903 Router Features

Network Timing Interfaces

The RSP supports the following network timing interfaces:

• BITS input/output port—RJ48 jack

• 1 PPS input and output—Mini coax connectors

• 2.048 or 10 MHz input and output—Mini coax connectors

• Time of Day (ToD) or 1 PPS input or output 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.

Temperature Sensor

The Cisco ASR 903 Router has a temperature sensor to detect overtemperature conditions inside the
chassis. The overtemperature detection trips at 75 degrees C +/- 5% with the ambient (inlet) trip point
at 67 degrees C. This condition is reported to the processor as an interrupt, and the softw are takes action
to generate the appropriate alarms.

Following is an explanation of the slot or port numbering:

• The n u m b e r i n g f o r m a t is Interface type slot or interface number. Inte r fa c e ( p o r t ) n u m b e r s b eg i n a t

logical 0 for each interface type.

• Interface module slots are numbered from bottom to top, with logical interfaces on each module

numbered from left to right. Interfaces are hard-wired. Therefore, port 0 is always logical interface
0/0, port 1 is always logical interface 0/1, and so on.
