THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT
TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS
MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY
PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following inform ation is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Route Processor 1 (RP1), the Cisco ASR 1000 Series Embedded Services Processor (ESP5, ESP10, and
ESP20), and the shared port adapters.

With the exception of the Cisco ASR 1002 Router, all FRUs (Cisco ASR 1000 Series Route Processor 1,
Cisco ASR 1000 Series Embedded Services Processor, and SPAs) are designed to work in the different
chassis models. (The Cisco ASR1000-ESP20 is not supported in the Cisco ASR 1002 Router.) The
power supplies and fan modules are chassis specific. The SPAs are supported in all chassis
configurations although there are SPA restrictions in the Cisco ASR 1002 Router.

Chassis Slot and Logical Interface Numbering

The Cisco ASR 1000 Series Routers have a slot numbering system located on both sides of the card
module location. The chassis slots are physically numbered from zero starting at the bottom of the
chassis. This section describes the slot numbering for the Cisco ASR 1000 Series Routers:

• Cisco ASR 1006 Router Slot Numbering, page 1-5

• Cisco ASR 1004 Router Slot Numbering, page 1-7

• Cisco ASR 1002 Router Slot Numbering, page 1-7

Cisco ASR 1000 Series SPA Interface Processor (SIP) subslots begin their numbering with “0” and have
a horizontal orientation. The SIP subslot numbering is indicated by a small numeric label beside the
subslot on the faceplate. Some commands allow you to display information about the SPA itself, such as
show idprom module and show hw-module subslot. These commands require you to specify both the
physical location of the SIP and SPA in the format, Slot/Subslot, where:

• Slot—Specifies the chassis slot number in the Cisco ASR 1000 Series Routers where the SIP is

installed.

• Subslot—Specifies a subslot of the SIP where the SPA is installed.

MAC Address Information

The Media Access Control (MAC) or hardware address is a standardized data link layer address that is
required for certain network interface types. These addresses are specific and unique to each port and
are not used by other devices in the network. The Cisco ASR 1000 Series Routers assign and control the
MAC addresses of its shared port adapters.

You can identify shared port adapter slots by using software commands. To display information about:

• All shared port adapter slots, use the show interfaces command.

• A specific shared port adapter slot, use the show interfaces command with the shared port adapter

type and slot number in the format show

interfaces port-adapter-type slot-number/port-number.

Note If you abbreviate the command (sh int) and do not specify shared port adapter type and slot number (or

arguments), the system interprets the command as show interfaces and displays the status of all shared
port adapters and ports.

The MAC addresses are assigned to the slots in sequence. For example, in the Cisco ASR 1006 Router,
the first address is assigned to slot 0 and the last address is assigned to slot 6. The actual MAC address
assignment is 16 MAC addresses per SPA slot for half-height SPAs and 64 per SPA slot for full-height
SPAs. Also, the Cisco ASR 1000 Series RP1 RP Management Ethernet port is assigned one MAC
address from the end of the pool and for a Cisco ASR 1006 Router with two Cisco ASR 1000 RP1s, each
ASR10000 RP1 is assigned one MAC address.

Using this address scheme, you can remove shared port adapters and insert them into other routers
without causing the MAC addresses to move around the network or be assigned to multiple devices.

Cisco ASR 1000 Series Aggregaion Services Routers Hardware Installation and Initial Configuration Guide

OL-13208-03

Chapter 1 Cisco ASR 1000 Series Routers Hardware Overview

If the MAC addresses were stored on each shared port adapter, online insertion and removal would not
function because you could never replace one shared port adapter with an identical one; the MAC
addresses would always be different. Also, each time a shared port adapter was replaced, other devices
on the network would have to update their data structures with the new address. If the other devices did
not update quickly enough, the same MAC address could appear in more than one device at the same
time.

Note Storing the MAC addresses for every slot in one central location means the addresses stay with the

memory device on which they are stored.

Online Insertion and Removal

In the modular chassis configurations, most Cisco ASR 1000 Series Router field-replaceable units
(FRUs) support online insertion and removal (OIR). However, the removal of critical non-redundant
FRUs will result in service interruption.

Functional Overview

Note As you disengage the shared port adapter from the router, online insertion and removal (OIR)

administratively shuts down all active interfaces in the shared port adapter.

Online insertion and removal (OIR) allows you to install and replace shared port adapters while the
router is operating; you do not need to notify the software or shut down the system power, although you
should not run traffic through the shared port adapter you are removing while it is being removed. Online
insertion and removal is a method that is seamless to end users on the network, maintains all routing
information, and preserves sessions.

All SPA OIR events are independent of one another. An OIR event of a single SPA does not affect the
other SPAs in that ASR1000-SIP10 or any other system function.

Note The Cisco ASR 1002 Router differs from the Cisco ASR 1006 and Cisco ASR 1004 routers. The Cisco

ASR

1002 Router supports the Cisco embedded ASR1000-RP1 which is a combined route processor and
carrier card which are not field-replaceable units. The Cisco ASR1000-ESP5 or ASR1000-ESP10 are

The following is a functional description of OIR for background information only; for specific
procedures for installing and replacing a shared port adapter in Cisco ASR 1000 Series Routers, refer to
the online configuration note for each shared port adapter.

When you remove or insert a shared port adapter in a Cisco ASR 1000 Series Router, the Control
Processor notifies the Cisco ASR1000-RP1, which in turn notifies the forwarding engine control
processor (FECP), and then performs as follows:

• Rapidly scans the midplane for configuration changes.

OL-13208-03

• Initializes all newly inserted shared port adapters, noting any removed interfaces and placing them

in the administratively shutdown state.

• Brings all previously configured interfaces on the shared port adapter back to the state they were in

when they were removed. Any newly inserted interfaces are put in the administratively shutdown
state, as if they were present (but not configured) at boot time. If a similar shared port adapter type
is reinserted into a slot, its ports are configured and brought online up to the port count of the
original SPA.

Functional Overview

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions allow you to maintain normal system operation by
identifying and resolving adverse conditions prior to loss of operation.

Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Over temperature

conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate
clearance around the sides of the chassis so that cooling air can flow through the chassis interior
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.

Environmental Monitoring

The environmental monitoring functions use sensors to monitor the temperature of the cooling air as it
moves through the chassis.

The local power supplies provide the ability to monitor:

• Input and output voltage

• Output current

• Outlet temperature

The router is expected to meet the following environmental operating conditions:

• Operating Temperature Nominal: 5° to 40°C

• Operating Temperature Short Term: 5° to 55°C

• Operating Humidity Nominal: 5% to 85% non-condensing

• Operating Humidity Short Term: 5% to 90% non-condensing

• Operating Altitude: 198 to 13,200 feet (60 to 4000 meters)

• DC Input Range: –40.5 to –72 VDC

• AC Input Range: 85 to 264 VAC

If the air temperature exceeds a defined threshold, the system controller displays warning messages on
the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts
down the system.

In addition, the power supplies monitor internal power supply temperatures and voltages. A power
supply is either within tolerance (normal) or out of tolerance (critical). If an internal power supply
temperature or voltage reaches a critical level, the power supply shuts down without any interaction with
the system processor.

The environmental monitoring functions use the following levels of status conditions to monitor the
system:

• Normal—All monitored parameters are within normal tolerances.

• Warning—The system has exceeded a specified threshold. The system continues to operate, but

operator action is recommended to bring the system back to a normal state.

• Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to

operate; however, the system is approaching shutdown. Immediate operator action is required.
