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 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.
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 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.

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
Minimum output voltage -36/18 VDC

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 Router RSP:
Supported RSP Features, page 1-7
RSP Redundancy, page 1-7

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,

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 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.
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.

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.

Interface Numbering

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.

Serial Number Label Location

Figure 1-9 shows the serial number label location on the Cisco ASR 903 Router.
Figure 1-9 Cisco ASR 903 Router Serial Number Location
Interface Numbering
The Cisco ASR 903 Router chassis includes:
Six interface module slots
Two RSP module slots
Two power supply slots
One fan tray slot
Each network interface on a Cisco ASR 903 Router is identified by a slot number and a port number.

Regulatory Compliance

Figure 1-10 shows interface numbering in a Cisco ASR 903 Router.
Figure 1-10 Cisco ASR 903 Router Slot Numbers
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.
Regulatory Compliance

Information for the Cisco ASR 903 Router document.
