This document contains instructions for installing (or replacing) the second-generation Channel
Interface Processor (CIP2) in the Cisco 7000 series routers and the Cisco 7500 series routers.
Important Note to Users The following Cisco Internetwork Operating System (Cisco IOS)
releases support the CIP2: Cisco IOS Release 10.2(13), or later, Release 10.3(13), or later,
Release 11.0(10), or later, or Release 11.1(5) or later.
Prior to these Cisco IOS releases being available, CIP2 is supported with a special microcode image.
This microcode image is available through download from Cisco Connection Online (CCO), on
diskettes shipped with the CIP2 when shipped separately from a system (as a spare), or is already in
Flash memory on a preconfigured system. For instructions on placing CIP2 microcode in Flash
memory, see the section “CIP2 Microcode” on page 37.
Once CIP2 microcode has been copied into Flash memory, a configuration command must be
specified to instruct the Cisco IOS to use this microcode image instead of the microcode image
bundled with your version of the Cisco IOS. For instructions on configuring the Cisco IOS to use a
CIP2 microcode image from Flash memory, refer to the section “Configuring Microcode” on
page 39.
For additional specific CIP2 software and hardware requirements, refer to the section “Software and
Hardware Prerequisites” on page 13. For complete and detailed descriptions of CIP2-related
interface and configuration commands, configuration options, and requirements, refer to the
publications listed in the section “If You Need More Information” on page 2.

What Is the CIP2
What Is the CIP2
This section discusses channel attachment and the CIP2, its LED functions, and its memory and
cable requirements.
Channel Attachment Overview
A mainframe channel (referred to as a channel) is an intelligent processor that manages the protocol
on the communications media and controls the data transfer to and from the main central processing
unit (CPU) storage. Devices called input/output processors (IOPs) communicate between the host
CPU and the channel. One IOP controls multiple channels, and there is no relationship between the
number of CPUs and the number of IOPs.
The channel relieves the mainframe CPU of direct communication with input/output (I/O) devices,
which saves processing cycles and allows data processing and communications tasks to run
concurrently. Channels use one or more channel paths as the links between mainframes and I/O
devices. I/O devices are connected directly to control units, which provide the logical capabilities
required to operate and control the I/O devices.
CIP2 Overview The CIP2 provides up to two channel-attached interfaces for Cisco 7000 series and Cisco 7500
series routers, eliminating the need for a separate front-end processor.
The CIP2 interfaces are combinations of a bus and tag (also called an original equipment
manufacturer’s interface [OEMI] and a parallel I/O interface) adapter and an Enterprise Systems
Connection (ESCON) adapter.
The bus and tag adapter is called the Parallel Channel Adapter (PCA), and the ESCON adapter is
called the ESCON Channel Adapter (ECA). The PCA and ECA connect directly to the CIP2, and
any combination of the two adapters can be used.
Note The ECA and PCA adapters can be upgraded or replaced (in the field) by a Cisco-certified
maintenance provider only. The CIP2 supports online insertion and removal (OIR), which allows
you to install or remove a CIP2 while the system is operating, without shutting down system power.
Caution To prevent system problems in Cisco 7000 series and Cisco 7500 series systems running
Cisco IOS images earlier than Cisco IOS Release 11.1(5), CIP2 (second-generation) cards must not
be installed in the same chassis system with CIP (first-generation) cards.

Second-Generation Channel Interface Processor (CIP2) Installation and Configuration 5
What Is the CIP2
CIP2 DescriptionThe CIP2 (see Figure 1) consists of a motherboard that is mounted on a metal carrier and one or two
ECA and/or PCA interfaces. (The CIP2’s readsChannel Interface Processor 2.) The ECA and PCA
interfaces attach to the motherboard by means of a multipin connector located at the rear edge of the
adapter. The CIP2 has two DRAM SIMMs (see Figure 1) and comes configured with 32 MB of
DRAM as the minimum standard (default) memory configuration. The CIP2 also has a Flash
memory device for storing the CIP2 microcode boot image. (See Figure 1.)
Figure 1 Channel Interface Processor, Horizontal Orientation
Note The ECA and PCA adapters can be upgraded or replaced (in the field) by a Cisco-certified
maintenance provider only.
Caution To prevent damage, and to prevent insertion problems caused by misalignment of the
adapters and motherboard, do not attempt to remove the adapters or motherboard from the carrier.
CIP2 Model Numbers
There are three CIP2 carrier types, which offer the following five interface adapter combinations:
•Single PCA on a PCA/ECA carrier (CX-CIP2-PCA1)
•Combination PCA and ECA (CX-CIP2-ECAP1)
•Single ECA on a dual ECA carrier (CX-CIP2-ECA1)
•Dual ECA on a dual ECA carrier (CX-CIP2-ECA2)
•Dual PCA on a dual PCA carrier (CX-CIP2-PCA2)

Bus and Tag CablesFollowing are descriptions and illustrations of the bus and tag cables.
Y Cable
The bus and tag cable with three 78-pin connectors (shown in Figure 5) has a DB-78 male (PCA)
connector on the CIP2 end, a DB-78 female connector on the next-control-unit end, and a DB-78
male connector on the from-host end.
Figure 5 PCA Bus and Tag Cable (CAB-PCA-Y)
The model number is CAB-PCA-Y (referred to as the Y cable)The male connector might be labeled
IN and is typically black, but can also be a dark gray. The female connector might be labeled OUT
and is typically light gray. The female OUT cable is nearest to the select/bypass switch, which is
discussed on the following page. (The IBM part number is 89F8392; however, this is subject to
change.)
Caution The Y cable must connected directly to the PCA. Do not connect any other cables directly
to the PCA.

Second-Generation Channel Interface Processor (CIP2) Installation and Configuration 11
What Is the CIP2
Note the switch marked S(for select mode) and B(for bypass mode). The switch is located on the
rear of the PCA connector. (See Figure 6.) The select/bypass switch is required to allow the cable to
be separated from the PCA without “opening” the select-out loop.
Caution To prevent halting the system or negatively affecting the mainframe operating system,
verify that the select/bypass switch is in bypass mode before you remove the PCA connector from
the CIP2.
Figure 6 Select/Bypass Switch on the Rear of the PCA Connector (CAB-PCA-Y Bypass Shown)
In select mode the PCA is operational, and the select-out signal is passed in a loop to all control lines
on the channel. All control units have a relay that shorts the incoming select-out signal to the
outgoing select-out signal when power is not applied to the control unit. When power is applied, the
relay is opened, and the signal is passed to the PCA.
Without the select/bypass switch in bypass mode, the channel would need to be taken offline before
servicing or replacing a CIP2. If the selected address does not match, the select-out signal is passed
to the next control unit. If the select-out signal gets all the way back to the channel, the control unit
being addressed is not present.
Note In bypass mode, the incoming select-out signal is shorted to the outgoing select-out signal,
bypassing the PCA and allowing other devices on the channel to function properly.
Caution Make sure you provide adequate strain relief for the heavy bus and tag cables that attach
to the PCA, to prevent damaging the PCA connector on the CIP2 by unintentionally disconnecting
the Y cable from the PCA connector.
VA and VB Cables
The two bus and tag cables with connector blocks have a DB-78 (male or female) connector on the
CIP2 end and 48-pin type-A connector blocks on the bus and tag ends. (See Figure 7.) VA and VB
cables are 56 inches (1.42 meters) in length.
For the bus and tag cable that attaches between the host and the PCA, the model number is
CAB-PCA-VA, and it is referred to as the VA cable. The female 78-pin connector might be labeled
IN and is typically light gray. The cable labeled P2 is bus, and the cable labeled P3 is tag. Looking
into the end of the female 78-pin connector (on the VA cable), with the wide part of the connector
D-shell on top, the P2 (bus) cable is on the right, and the P3 (tag) cable is on the left. The plastic on
the ends of the bus and tag connectors might be black or dark gray.
H2445

12 Second-Generation Channel Interface Processor (CIP2) Installation and Configuration
What Is the CIP2
The IBM part number is 12G8058; however, this is subject to change. The VA cable ships with a
terminator; the Cisco model number CAB-PCA-VA includes this terminator. The terminator and VA
cable together have the IBM part number 12G7988; however, this is subject to change.
For the bus and tag cable that attaches between the next control unit and the PCA, the model number
is CAB-PCA-VB, and it is referred to as the VB cable. The male 78-pin connector might be labeled
OUT and is typically black or dark gray. The cable labeled P2 is bus, and the cable labeled P3 is tag.
Looking into the end of the male 78-pin connector (on the VB cable), with the wide part of the
connector D-shell on top, the P2 (bus) cable is on the left, and the P3 (tag) cable is on the right. The
plastic on the ends of the bus and tag connectors might be light gray (as opposed to the black or dark
gray plastic on the VA cable). The IBM part number is 12G7933; however, this is subject to change.
Caution To prevent potential system problems, do not connect the VB cable directly to the PCA.
You must connect the Y cable to the PCA, then connect the VB cable to the Y cables as appropriate.
Figure 7 PCA Bus and Tag, VA and VB Cables
The Y cable always attaches to the PCA. The VA cable attaches between the male end of the Y cable
and the host. The VB cable attaches between the female end of the Y cable and the next (or new)
control unit. Do not connect the VB cable directly to the PCA. If the PCA is the last control unit,
channel termination is required at the end of the Y cable that points away from the host. (See
Figure 5.) For attachment instructions refer to the section “Attaching the CIP2 to the Channel” on
page 30.

Safety Guidelines
This section lists safety guidelines you should follow when working with any equipment that
connects to electrical power or telephone wiring.
Electrical EquipmentFollow these basic guidelines when working with any electrical equipment:
•Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
•Disconnect all power and external cables before moving a chassis.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Telephone Wiring Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
ESD damage, which can occur when electronic cards or components are improperly handled, results
in complete or intermittent failures. Each processor module contains a printed circuit card that is
fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are
integral components of the carrier. Although the metal carrier helps to protect the board from ESD,
use an ESD-preventive wrist or ankle strap whenever you handle any electronic system component.
Following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
•When you work at the interface processor end of the chassis, connect the equipment end of the
strap to a captive installation screw on an installed interface processor, or to any unpainted
chassis surface.
•When you install a processor module, use the ejector levers to properly seat the bus connectors
in the backplane, then tighten both captive installation screws. These screws prevent accidental
removal, provide proper grounding for the system, and help to ensure that the bus connectors are
seated in the backplane.

16 Second-Generation Channel Interface Processor (CIP2) Installation and Configuration
Installation Prerequisites
•Handle processor modules by the carrier handles and carrier edges only; never touch the board
or any connector pins.
•When you remove a processor module, place it card side up on an antistatic surface or in a static
shielding bag. Immediately place the module in a static shielding bag if you need to return it to
the factory.
•Avoid contact between electronic equipment and clothing. Antistatic straps only protect the
equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Caution For safety, periodically check the resistance value of the antistatic strap. The
measurement should be between 1 and 10 megohms.
Online Insertion and Removal—An Overview
The OIR feature allows you to remove and replace interface processors while the system is
operating; you do not need to notify the software or shut down the system power.
Note This section describes the mechanical functions of the system components and emphasizes
the importance of following the correct procedures to avoid unnecessary board failures. This section
is for background information only; specific procedures for the CIP2 are contained in the following
sections.
Each interface processor contains a male connector with which it connects to the system backplane.
Each card (male) connector comprises a set of tiered pins, in three lengths. The pins send specific
signals to the system as they make contact with the backplane. The system assesses the signals it
receives and the order in which it receives them to determine what event is occurring and what task
it needs to perform, such as reinitializing new interfaces or shutting down removed ones.
For example, when inserting an interface processor, the longest pins make contact with the
backplane first, and the shortest pins make contact last. The system recognizes the signals and the
sequence in which it receives them. The system expects to receive signals from the individual pins
in this logical sequence, and the ejector levers help to ensure that the pins mate in this sequence.
When you remove or insert an interface processor, the backplane pins send signals to notify the
system, which then performs as follows:
1Rapidly scans the backplane for configuration changes.
2Initializes all newly inserted interface processors, noting any removed interfaces and placing
them in the administratively shut down state.
3Brings all previously configured interfaces on the interface processor back to the state they were
in when they were removed. Any newly inserted interfaces are put in the administratively shut
down state, as if they were present (but unconfigured) at boot time. If a similar interface
processor type has been reinserted into a slot, its ports are configured and brought on line up to
the port count of the original interface processor.
The system brings on line only interfaces that match the current configuration and were previously
configured as up; all others require that you configure them with the configure command.
OIR functionality enables you to add, remove, or replace interface processors with the system on
line, which provides a method that is seamless to end users on the network, maintains all routing
information, and ensures session preservation.

contact a customer service representative for ordering information.
•Number 2 Phillips or one-quarter-inch flat-blade screwdriver for the captive installation screws
on the CIP2. (Although most interface processors use slotted screws, some interface processor
carriers use Phillips screws.)
•A new CIP2 with one of the product numbers listed on page 1 or in the section “CIP2 Model
Numbers” on page 5.
•The appropriate cables for your CIP2 type: bus and tag for a PCA (with terminal blocks or 78-pin
connectors) and/or ESCON fiber with duplex connectors for an ECA.
•ESD-preventive wrist strap or other device for preventing ESD damage.
•Interface processor filler (MAS7K-BLANK) if you are removing a CIP2 and not installing a new
CIP2 or other interface processor in the empty slot.
Microcode Overview
Microcode, also known as firmware, is a set of processor-specific software instructions that enables
and manages the features and functions of a specific processor type. At system startup or reload, the
system loads the microcode for each processor type present in the system.
The CIP2 microcode boot image resides in a Flash memory device on the CIP2 motherboard. The
entire CIP2 microcode image is delivered on a Flash memory card, on floppy disks, or is available
via download from CCO.
New microcode is released to enable new features, improve performance, or fix bugs in earlier
versions. The Cisco 7000 series and Cisco 7500 series routers feature downloadable software and
microcode for most upgrades. These features enable you to download new (upgraded) images
remotely, store the images in router memory, and load the new images at system startup without
having to physically access the router. You can store multiple versions for a specific processor type
in Flash memory, and use configuration commands to specify which version the system should load
at startup. All interfaces of the same type (for example, all CIP2s) use the same microcode image.
Caution To ensure proper operation of the CIP2, and to preclude system problems, you should use
only the CIP2 microcode image that is recommended for the version of Cisco IOS you are running.
By default, the CIP2 microcode is loaded from either the flash memory (if you have a 7000 and 7010
with a RP) or the Flash memory card in slot0. The default version can be found by entering the show
microcode command.

What Is the Cisco 7000 Series?
The Cisco 7000 series consists of the Cisco 7000 and Cisco 7010 routers.
Note For specific software and hardware requirements for the Cisco 7000 series systems, refer to
the section “Software and Hardware Prerequisites” on page 13.
In the Cisco 7000, slot 5 is reserved for the RSP7000 (7000 RSP slot shown in Figure 8), which
contains the system processor and performs packet switching functions; slot 6 is reserved for the
RSP7000CI (7000 CI slot shown in Figure 8), which contains all of the environmental monitoring
functionsfor the Cisco 7000. The remaining fiveslots (slots 0 through4) are for interfaceprocessors,
including the CIP2.
