Product Overview
Product Overview
The Performance Routing Engine 4 (PRE4) is the fifth generation parallel express forwarding (PXF)
packet processing and scheduling engine for the Cisco 10008 router. Figure 1 shows the front of the
Cisco 10008 router.
Figure 1 Cisco 10008 Router Chassis—Front View
The PRE4 performs all Layer 2 and Layer 3 packet manipulation related to routing and forwarding
through the Cisco 10008 router. Its advanced application-specific integrated circuit (ASIC) technology
supports very high performance throughput with IP services enabled on each port.
The PRE4 consists of two main logical and physical cards:
•The fast packet (FP) card—Performs fast path forwarding and output scheduling.
•The route processor (RP) card—Contains the configuration, management route processing engine,
and backplane interconnect. The FP card plugs into the RP card.
The PRE4 runs Cisco IOS Release 12.2(33)SB and later releases. Benefits of the PRE4 include:
1Blower module 5PRE4—slot 0A
2Primary Power Entry Module (PEM) 6PRE4—slot 0B
3Redundant PEM 7Line card slots 5 to 8
4Line card slots 1 to 4

Cisco 10008 Router PRE4 Installation and Configuration Guide
OL-13840-01
Product Overview
•800-MHz dual processor
•Sixty-four PXF network processors arranged as 8 columns and 8 rows
•512 MB packet buffer and 128 MB control memory with error-correcting code (ECC)
•4 GB ECC-protected route processor (RP) memory
•10 million packets per second (Mpps) forwarding performance through the PXF complex
•5.6 Gbps backplane bandwidth for each full-height backplane slot
•11.2 Gbps backplane bandwidth to each SPA interface processor (SIP)
•Maximum transmission unit (MTU) support of 9216 bytes
•An external CompactFlash slot (Disk0)
•A 100/1000 Mbit Ethernet interface for communication between two redundant PRE4.
•Full backward compatibility with all existing line cards supported on the Cisco 10008 router
•Hierarchical Queueing Framework (HQF) that provides up to three levels of service granularity
By centralizing packet processing in the PRE4, the Cisco 10008 router architecture frees up space on
line cards, enabling high interface density, yet retaining the compact Network Equipment Business
Systems (NEBS) transmission equipment form factor.
Redundant PRE4
You can configure two PRE4 in a single chassis for redundancy. If the active PRE4 fails, the standby
PRE4 automatically takes over operation of the router. Because all the line cards are physically
connected to both the active and standby PRE4, the failure of a single PRE4 does not require user
intervention.
If a failure occurs, all line cards automatically reset to the redundant PRE4. Startup and running
configurations of the standby PRE4 are synchronized with the active PRE4, ensuring the fastest possible
cut-over time if the active PRE4 fails.
PRE4 Front Panel

Product Overview
PRE4 Connectors
The front panel on the PRE4 contains three ports with RJ-45 connectors.
•Console port (CONSOLE)—This asynchronous serial port is used to connect a terminal to the PRE4
for local administrative access.
•Auxiliary port (AUX)—This asynchronous serial port is used to connect a modem to the PRE4 for
remote administrative access.
•NME Port—This Ethernet port is used to connect the PRE4 to a Fast Ethernet port.
CompactFlash Card Slot
The external CompactFlash slot can store the Cisco IOS image or a system configuration file on a flash
memory card. The system can also boot from the software stored on the flash memory card.
LED Indicators and Buttons
The LEDs on the PRE4 front panel provide a visual indication showing the status of PRE4 operation.
Table 2 describes the PRE4 LEDs and buttons.

Alphanumeric Display
The alphanumeric display on the front panel provides information on the state of the PRE4. The display
consists of two 4-character LED panels. Table 3 describes the most common messages. If you report a
problem to Cisco, it is helpful to include the message on the PRE4 alphanumeric display in your problem
report.
CRITICAL, MAJOR,

Off No alarm.
Note Alarm relay contacts can be used to connect the router
to an external visual or audio alarm system. This feature
enables any CRITICAL, MAJOR, or MINOR alarms
generated by the router to activate the visual or audible
alarms. Shutting off an audible alarm does not disable
the alarm LEDs.

Safety Guidelines
Before you begin the PRE4 installation procedure, review the safety guidelines in this section to avoid
injuring yourself or damaging the equipment. Before you install, configure, or perform maintenance on
the router, you should also review the safety warnings listed in the Regulatory Compliance and Safety
Information for the Cisco 10000 Series Routers document.

Safety Warnings
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may
harm you. A warning symbol precedes each warning statement. The following warning is an example of
a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard.
Warning IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar
with standard practices for preventing accidents. Use the statement number provided at the end of
each warning to locate its translation in the translated safety warnings that accompanied this device.
Statement 1071
SAVE THESE INSTRUCTIONS
Note If you need translations of the safety warning, see the Regulatory Compliance and Safety Information
for Cisco 10000 Series Routers document.
Software Compatibility
The PRE4 has specific Cisco IOS software requirements. Table 4 shows the minimum required Cisco
IOS software for the PRE4.
Use the show version command to display the system software version that is currently loaded and
running.
If the output of the show version command indicates that the Cisco IOS software is a version earlier than
the version identified as the minimum Cisco IOS software release in Table 4, check the contents of the
CompactFlash memory to determine if the required images are available on your system.
The output of the show flash command provides a list of all files stored in the CompactFlash memory.
If the correct software version is not installed, contact Cisco Customer Service (see the “Obtaining
Documentation, Obtaining Support, and Security Guidelines” section on page 68).
Installation Guidelines
This section contains guidelines for the following:
•A new installation
•A replacement installation
•The required tools and equipment

Cisco 10008 Router PRE4 Installation and Configuration Guide
OL-13840-01
Installation Guidelines
The PRE4 is hot-swappable, which means you can remove and replace a PRE4 while the system is
operating—if you have a standby (redundant) PRE4 installed in the chassis. This feature allows you to
add, remove, or replace a PRE4 while the system maintains all routing information and ensures session
preservation.
Caution Replacing the active PRE4 in a non-redundant chassis (no standby PRE4) causes a system shutdown and
stops all traffic. If possible, alert all subscribers that the system will not be functioning during the
replacement. The line cards shutdown automatically due to the hardware Online Insertion and Removal
(OIR) interlock in their power systems.
Caution To prevent electrostatic discharge (ESD) damage, handle the PRE4 by the faceplate or the card carrier
edges only. Avoid touching the printed circuit board and its components, or any connector pins.
New Installation Guidelines
If you are replacing the PRE4 in a non-redundant system, you must configure the PRE4 using the
configure command. For configuration information, refer to the “Configuring a PRE4” section on
page 19.
Replacement Installation Guidelines
If the PRE4 is replaced in a redundant system containing two PRE4, the standby (or newly installed)
PRE4 automatically assumes the configuration of the active PRE4; do not configure the new PRE4.
Required Tools and Equipment
You need the following tools and equipment to install the PRE4:
•A 3/16-inch flat-blade screwdriver
•An ESD-preventive wrist or ankle strap with connection cord
•A terminal console to connect to the PRE4 after it is installed
Powering Off the System
Use the following steps to power down the system:
Caution If you have redundant Power Entry Modules (PEMs), set both power switches to the off (0) position. See
Figure 3 for the DC PEM power switch and Figure 4 for the AC PEM power switch.
Step 1 Attach an antistatic strap to your wrist or ankle and to an ESD socket on the chassis, or to a bare metal
surface on the chassis or frame.
Step 2 Set the power switch to the off (0) position.
