• AC Pow er Specifications, page 1-5
Redundancy The Cisco ASR 903 Router chassis includes a slot for an optional redundant po wer supply . The
redundant power supply option p rovides a second, identical power sup ply 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 po wer supplies.
If you install a redundant po wer su pply 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.
Dying Gasp The Cisco ASR 903 Router DC power supply supports the Dying Gasp feature, which allows th e 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 po wer supply , the router supports a
minimum input power loss detect ion time of 2 milliseconds (DC) and continued operation of at least 6
milliseconds (DC) after the notification.
Note Continued DC power supply operat ion may vary for voltages other t han +24/-48V .
Status LEDs LEDs are also provided on each power supply to indicate the status of the input po wer and the health of
the power supply . For more inform ation about the LEDs on the Cisco ASR 903 Router, see Ch apter 5,
“Troubleshooting. ”
DC Power Specifications The Cisco ASR 903 Router uses a +24/-48 V olts Direct Current (VDC) (-19 to -72 VDC supply
tolerance) power supply . The power supply provides 550 W output power fo r 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 remov al, and two status LEDs. No ON/OFF switch is provided.

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, red undancy, external management , and system status
indications on the router .
The following sections describe the Cisco ASR 903 Rout er RSP:
• Supported RSP Features, page 1-7
• RSP Redundancy, page 1-7
• Network Timing Interf aces, page 1-8
• RSP Interfaces, page 1-8
RSP features include:
• Loading software onto processor-based interface mod ules
• Redundant RSP management—The RSP manages detection of RSPs, exchange of health and status
information, role negotiation, fun ction for detection, health and status exchange, role ne gotiation
• Packet processing

Cisco ASR 903 Router Features
• Traff ic management, including buf fering, queuing, and scheduling, Ethernet MA C functions
• Network clocking functions including phase and time-o f-day for BITS, 1 PPS, 10 MHz, and 1588
PTP clock references.
• Storage of software images, system configurat ion, 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 do wnstream 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 memo ry, 3 -Mb buffer table,
576-Mb forwarding memory , and 1,536-Mb packet b uffer 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, b ut they hav e the same interfaces and
functionality .
Supported RSP Features The RSP provides the following feat ures on the Cisco router:
• Centralized data plane, timing, and control plane functions for the sy stem
• High-level control of interface modules
• Management functionalities for the router
• Control plane (host) CPU and associated memory in which IOS-XE and plat form control software
runs
• Nonvolati le memory for storage of software images, configurations, and system f iles
• 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 failu re of the active RSP results in an automatic switcho ver to the standby RSP .
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 sup ported.

Interface Numbering Temperature Sensor The Cisco ASR 903 Router has a temperature sensor to detect overt emperature conditions inside the
chassis. The overtemperature detection trips at 75 de grees 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.
Serial Number Label Location Figure 1-9 shows the serial number lab el location on the Cisco ASR 903 Router.

Interface Numbering
The Cisco ASR 903 Router chassis includes:
• Six interface module slots
• T wo RSP module slots
• T wo power supply slots
• One fan tray slot
Each network interface on a Cisco ASR 903 Router is identified by a slot number and a por t number.

Regulatory Compliance Figure 1-10 shows inter face numbering in a Cisco ASR 903 Router.
Figure 1 -10 Cisco ASR 903 Router Slot Numbers
Following is an e xplanation 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 i nterfaces 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 o n.
