Dying Gasp
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.
Caution
Dying Gasp
Status LEDs
To comply with IEC 61850-3 (voltage interruptions), redundant power supplies with separately derived power
feeds are required.
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.
Note
Dying Gasp is not supported on the ASR 900 RSP3 module for 1200W DC power supply.
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.

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
Note
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.
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
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.
