• AC Power Specifications, page 1-5
Redundancy
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 power supply fails or input power on one line fails. The
Cisco ASR 903 Router supports current sharing between the power supplies.
If you install a redundant power supply on the Cisco ASR 903 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 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 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.
Table 1-2 summarizes the input power specifications for the Cisco ASR 903 Router DC power supply.

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

how to install the fan tray, see Installing the Fan Tray, page 3-8. For a summary of the LEDs on the fan
tray, see “LED Summary” section on page 5-7.
RSP Modules
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, redundancy, 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

• 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 recovering network timing (frequency, 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.
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 power 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.
Note If you are using redundant RSPs, both the RSPs must be of the same type because a mixed configuration
of two different RSP types is not supported.

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.
