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 information 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.

Introduction

CHAPTER

Introducing the Cisco Wide Area Application Engine

This chapter provides a basic functional overview of the Cisco Wide Area Application Engine 7326 (WAE-7326), and describes the hardware, major components, and front and back panel indicators and controls.

This chapter contains the following sections:

• Introduction, page 1-1

• Software Functional Description, page 1-4

• Hardware Features, page 1-6

The Wide Area Application Engine (WAE-7326) supports three different software installations that provide a comprehensive set of services for the remote office: Cisco Wide Area Application Services (WAAS) software, Cisco Wide Area File System (WAFS) software and Cisco Application and Content Networking System (ACNS) software.

The following software releases support the WAE-7326 appliance:

OL-6831-02

• WAAS 4.0.1 and later

• WAFS 3.0 and later

• ACNS 5.3.3 and later

The WAE-7326 has a baseboard management controller that provides environmental monitoring for the appliance. If environmental conditions exceed thresholds or if system components fail, LEDs on the baseboard management indicate the problem. The error log also lists all critical errors. The baseboard management controller also provides remote server management capabilities through the OSA SMBridge management utility program.

Note The baseboard management controller is also known as the service processor.

Csico Wide Area Application Engine 7326 Hardware Installation Guide

OL-6831-02

Chapter 1 Introducing the Cisco Wide Area Application Engine

The WAE-7326 includes two integrated Broadcom Gigabit Ethernet controllers, which support connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network.

The WAE includes large data-storage and hot-swap capability. The WAE-7326 supports up to six 25.4 mm (1-inch) slim, 3.5-inch hot-swap hard disk drives installed on Ultra-Slim hard disk drive trays in the hot-swap bays. With the hot-swap feature, you can add, remove, or replace hard disk drives without powering down the appliance.

Note The WAE-7326 hardware supports installing (hot-swapping) hard disk drives

without powering off the device. However, Cisco software applications that run on the WAE-7326 appliance do not support hot-swapping. You must reload the WAE appliance before the software recognizes the new hard disk drives.

The Active Memory feature of your WAE-7326 improves the reliability of memory through memory mirroring and online spare memory. Memory mirroring stores data in two pairs of DIMMs simultaneously. Online spare memory disables a failed pair of DIMMs from the system configuration and activates a pair of online spare memory DIMMs.

Your WAE also includes a large system-memory capacity. The memory bus supports up to 16 GB of system memory. The memory controller supports error correcting code (ECC) for up to eight industry-standard, 1.8 V, 240-pin, double-data rate (DDR) II, PC3200, registered SDRAM DIMMs.

Introduction

OL-6831-02

The addition of an optional network interface card (NIC) in the WAE-7326 provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associated with this primary connection is automatically switched to the redundant Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.

The WAE-7326 supports up to two Intel Xeon microprocessors. If the appliance comes with only one microprocessor, you can install an additional microprocessor to enhance performance and provide symmetric multiprocessing (SMP) capability.

Chapter 1 Introducing the Cisco Wide Area Application Engine

Software Functional Description

The operation of the WAE is dependent on the software application that is installed on it. This section describes WAAS, ACNS and WAFS software:

• WAAS Software Description, page 1-4

• ACNS Software Description, page 1-5

• WAFS Software Description, page 1-5

WAAS Software Description

With WAAS software installed, the WAE appliance functions as either a WAAS Central Manager or a WAAS Application Acceleration Engine. The WAAS Central Manager provides a graphical user interface to monitor and configure all Acceleration Engines. The WAAS Acceleration Engine is deployed in remote branch offices and in the data center to accelerate TCP applications that access data across the network.

The Application Acceleration Engine functionality operates at different levels based on the software licenses purchased. WAAS 4.x, software offers the WAAS Transport License or the WAAS Enterprise License options.

Cisco WAAS software helps enterprises meet the following objectives:

1-4

• Provide branch office employees with LAN-like access to information and

applications across a geographically distributed network.

• Migrate application and file servers from branch offices into centrally

managed data centers.

• Minimize unnecessary WAN bandwidth consumption through the use of

advanced compression algorithms.

• Provide print services to branch office users. Cisco WAAS allows you to

configure a WAE as a print server so you do not need to deploy a dedicated system to fulfill print requests.

• Improve application performance over the WAN by addressing the following

common issues:

–

Low data rates (constrained bandwidth)

–

Slow delivery of frames (high network latency)

–

Higher rates of packet loss (low reliability)

Csico Wide Area Application Engine 7326 Hardware Installation Guide

OL-6831-02

Chapter 1 Introducing the Cisco Wide Area Application Engine

ACNS Software Description

With ACNS software installed, the WAE appliance functions as a Content Distribution Manager, Content Engine, or Content Router. The Content Distribution Manager provides a graphical user interface to manage registered Content Engines and Content Routers. The ACNS solution addresses the need to distribute and receive high-bandwidth, media-rich content across the Internet or an intranet without performance losses or content-delivery delays.

ACNS software offers the following content-based services:

• Content caching and hosting

• Proxy services

• Content replication

• Video streaming

In Content Engine mode, the WAE operates either as a component of an ACNS network or as a standalone content-caching device and is generally positioned on the WAN edge between your enterprise network and the Internet.

Software Functional Description

Note The WAE-7326 supports device-mode configuration and can be configured with

ACNS 5.x software to operate as a Content Engine, a Content Router, a Content Distribution Manager, or an IP/TV Program Manager.

To deploy Cisco Content Engines with Cisco ACNS software within your existing network, your network must support Cisco IOS software and the Web Cache Communication Protocol (WCCP). WCCP transparently redirects HTTP requests to a Content Engine, and the Content Engine responds to those requests.

WAFS Software Description

With WAFS software installed, the WAE appliance functions as a File Engine. The File Engine is an Internet file delivery device that provides the following file-based services:

• Segment-level file and metadata caching

• Protocol-specific latency reduction

• WAN transport-level optimization

Statement 1021

OL-6831-02

Chapter 1 Introducing the Cisco Wide Area Application Engine

The WAE-7326 has three Ethernet connectors. Two of the Ethernet connectors are attached to the Ethernet controllers. The Ethernet controllers are integrated on the system board. They provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in the server support auto-negotiation, the controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operate at that rate and mode. You do not have to set any jumpers or configure the controllers. However, you must install a device driver to enable the operating system to address the controllers.

The third Ethernet connector is the Remote Supervisor Adapter II SlimLine Ethernet connector. Use this connector to enable remote server management through a network. This connector is active only if an optional Remote Supervisor Adapter II SlimLine is installed.

Ultra320 SCSI Controller System Board Connectors

The WAE-7326 has one SCSI LVD port connector located on the back panel. The integrated dual-channel SCSI controller with integrated RAID supports two independent Ultra320 SCSI channels: one external and one internal. Each channel supports up to 15 SCSI devices. You can use the external LVD SCSI channel connector on the rear of the server to connect different types of SCSI devices, such as drives or printers.

This controller uses the following features to perform these actions:

• Double-transition clocking to achieve up to 320 MB-per-second data-transfer

rates.

• Domain-name validation to negotiate compatible data-transfer speeds with

each device.

• Cyclic redundancy checking (CRC), instead of the usual parity checking, to

improve data reliability.

• An active terminator for SCSI bus termination.

SCSI IDs

1-14

The WAE-7326 has one SCSI cable, which connects the internal connector on the system board to the standard hot-swap-drive backplane. If you plan to attach external SCSI devices, you must order additional cables. To select and order the correct cables for use with external devices, contact your Cisco marketing representative or authorized reseller.

Each SCSI device that is connected to a SCSI controller must have a unique SCSI ID. This ID enables the SCSI controller to identify the device and ensures that different devices on the same SCSI channel do not attempt to transfer data

• Form and Function

• Ports and LED Indicators

• Inline Network Adapter Cabling Requirements

• Installation Scenarios and Cabling Examples for Fast Ethernet Connections

For adapter specifications, see Table A-3 in Appendix A.

Form and Function

Your appliance supports one optional 4-port Ethernet inline network adapter. The inline network adapter is a full-height, three-quarter-length PCI-X network interface card that contains four independent Gigabit Ethernet ports. (See

Figure 1-9.)

Figure 1-9 Inline Network Adapter

The Cisco WAE inline network adapter provides inline traffic interception capability for your appliance. When your appliance is configured for inline interception mode, you can set attributes to control which interfaces are to be used over which VLANs. By default, the adapter operates on all inline-capable interfaces and VLANs. You can configure the inline redirection feature using the WAAS 4.0.7 CLI or the WAAS 4.0.7 Central Manager GUI.

Csico Wide Area Application Engine 7326 Hardware Installation Guide

OL-6831-02

Chapter 1 Introducing the Cisco Wide Area Application Engine

The WAAS software defines two new interface types: A group interface that represents an inline pair grouping and a port interface that represents the individual port. These interfaces are referred to as inlineGroup and inlinePort, respectively.

InlineGroup interfaces are numbered using the format slot/group. The slot number is the slot in which the adapter is inserted. (In the WAE 500 series and 600 series appliances, the adapter must be installed in slot 1 only.) The group number is either 0 or 1 (each adapter has 2 group pairs). The group number is displayed on the adapter label.

InlinePort interfaces are numbered slot/group/lan or slot/group/wan. The last attribute is the LAN or WAN designator.

The inline network adapter also includes an onboard programmable Watch Dog Timer (WDT) controller. You can set the time to wait after a failure event, such as a power outage or a kernel crash, before the unit begins to operate in mechanical bypass mode. In mechanical bypass mode, traffic is bridged between the LAN and WAN ports of each group. Mechanical bypass mode prevents the WAE from becoming a single point of failure and allows traffic to continue to flow between the router and the client while it passes through an unresponsive WAE without being processed.

For more information about configuring the inline network adapter, see the Cisco

Wide Area Application Services Configuration Guide.

Inline Network Adapter Cabling Requirements

Your inline network adapter ships with two types of cables: crossover and straight-through. When you connect the WAE inline network adapter, proper cabling depends on the link speed (Gigabit Ethernet or Fast Ethernet) and the types of devices (DCE or DTE) being connected.

Note You must retain the same link speed from one end of the connection to the other

end. Inline adapter interfaces are able to autonegotiate link speeds. If any of your connecting interfaces are configured for Fast Ethernet (whether on a switch or a router), your WAE inline adapter uses Fast Ethernet. If any of your connecting interfaces are configured for Gigabit Ethernet, your WAE inline adapter uses Gigabit Ethernet. Speed and duplex settings are port-specific, so two inline ports can negotiate different speeds independently.

If you are connecting a WAE inline appliance between two devices using Gigabit Ethernet, you can use either straight-through cables, crossover cables, or any combination of the two cable types, regardless of the type of device. However, for consistency, we recommend that you use straight-through cables for all Gigabit Ethernet connections.

Table 1-7 shows the cable requirements for WAE and non-WAE connections when

you are using Gigabit Ethernet end to end.

WAE to WAE Crossover or Straight-through

Some switches support automatic medium-dependent interface crossover (MDIX). You can configure MDIX by using the mdix auto global configuration switch command. If your switch supports MDIX, you do not need to follow these cabling rules because MDIX automatically adjusts transmit and receive pairs when an incorrect cable type (crossover or straight-through) is installed on a 10/100 Fast Ethernet port. However, when you configure MDIX, you must also configure the port to use autosense (not manual selection of speed/duplex).

of the WAE inline appliance, you must consider the types of devices that are being connected, and you must use the correct cables. You must follow these cabling instructions for the inline network adapter to work properly. (See Tabl e 1- 8 . For illustrations and examples, see the “Installation Scenarios and Cabling Examples

for Fast Ethernet Connections” section on page 1-22.)

Crossover or Straight-through

1-20

To connect the inline network adapter using the correct cables for Fast Ethernet connections, follow these steps:

Step 1 Determine which type of cable you would use for a direct connection between

your two end devices (without a WAE inline network appliance connected between them) by using the following standard cabling rules:

• When you are directly connecting two network devices that are similar, such

as two switches, use a crossover cable.

• When you are directly connecting two network devices that are different, such

as a switch and router, use a straight-through cable.

Csico Wide Area Application Engine 7326 Hardware Installation Guide

OL-6831-02

Chapter 1 Introducing the Cisco Wide Area Application Engine

Note Because the inline network adapter has an internal crossover connection

that becomes active when the InlineGroup interface is placed in mechanical bypass mode, you must figure out which cable you would use to connect the two network devices directly, and then you must install the other cable type (on one side, usually the WAN side of the inline appliance) instead.

Table 1-8 shows the cable requirements for WAE and non-WAE connections when

you are using Fast Ethernet end to end.

Step 2 Connect Fast Ethernet ports on both the LAN and the WAN sides of the WAE

inline appliance by using the following cable types:

• On the LAN side of the connection, use a straight-through cable between the

WAE inline appliance and the network device.

• On the WAN side of the connection, use the cable that is different from the

cable that you would use to connect the two network devices directly (as determined in Step 1).

Csico Wide Area Application Engine 7326 Hardware Installation Guide

1-21

Chapter 1 Introducing the Cisco Wide Area Application Engine

Hardware Features

For example, if you are connecting a router and a switch (two different devices) through the WAE inline appliance, use a straight-through cable on the LAN side of the connection and use a crossover cable on the WAN side of the connection. (If you were connecting the two different devices directly, you would use a straight-through cable, so use the crossover cable instead.)

If you are connecting two switches (or two similar devices), use straight-through cables on both the LAN and the WAN sides of the WAE inline appliance.

Figure 1-11 through Figure 1-13 show the cables to use for the WAE LAN

and WAN connections between Fast Ethernet ports.

Installation Scenarios and Cabling Examples for Fast Ethernet Connections

WAE appliances can be installed physically between two network devices (such as the branch office router and branch office LAN switch) by connecting the WAE inline network adapter ports to the network devices using the proper cables.

If you are connecting a WAE inline appliance between two devices using Gigabit Ethernet, you can use either straight-through cables, crossover cables, or any combination of the two cable types, regardless of the type of device. This section shows cabling examples for Fast Ethernet connections only, because Fast Ethernet has specific cabling requirements.

The inline network adapter has four ports that are divided into two inline groups (see the “Ports and LED Indicators” section on page 1-18). The WAE can be physically placed inline between two distinct network paths, creating redundant WAN links. (See Figure 1-11.)

1-22

Two WAEs with inline network adapters can also be installed back-to-back in a serial fashion between two network devices for failover purposes. In this type of serial cluster configuration, if one WAE fails or becomes overloaded, the other WAE can provide optimization. (See Figure 1-12.)

Note When you connect two WAE inline appliances to each other in serial fashion,

always use a crossover cable between the two WAEs. (See Figure 1-13.)

into the appliance as you lean over it.

• Avoid dropping any metallic objects, such as paper clips, hairpins, or screws,

into the appliance.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the appliance. To prevent static damage, discharge static electricity from your body before you touch any of your system’s electronic components. You can do so by touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

• When unpacking a static-sensitive component from its shipping carton, do not

remove the component from the antistatic packing material until you are ready to install the component in your system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

Installing the Chassis on a Tabletop

When you install a WAE on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following points:

• The chassis should be installed off the floor. (Dust that accumulates on the

floor is drawn into the interior of the chassis by the cooling fans. Excessive dust inside the WAE can cause overtemperature conditions and component failures.)

Installing the Wide Area Application Engine 7326

OL-6831-02

• There must be approximately 19 inches (48.26 cm) of clearance at the front

and rear of the chassis for accessing network cables or equipment.

• The WAE will receive adequate ventilation (it is not being installed in an

enclosed cabinet where ventilation is inadequate).

To install the WAE on a workbench or tabletop, follow these steps:

Step 1 Remove any debris and dust from the tabletop or workbench, as well as from the

surrounding area. Also make sure that your path between the WAE and its new location is unobstructed.

Step 2 Attach the rubber feet to the bottom of the chassis. The rubber feet have an

adhesive backing. Peel the protective tape off the adhesive and stick the feet to the bottom of a clean chassis surface. Place one foot in each corner.

Step 3 Place the chassis on the tabletop or workbench.

Step 4 Ensure that no exhaust air from other equipment will be drawn into the chassis.

Also make sure that there is adequate clearance at the front and rear of the chassis.

Removing or Replacing a WAE

3-14

Warning

Cisco Wide Area Application Engine 7326 Hardware Installation Guide

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Ultimate disposal of this product should be handled according to all national laws and regulations.

To remove a WAE from your network, power it down, disconnect the power cords and network cables, and physically remove the chassis from the rack.

The WAE is in constant communication with the router on your network. When the router notices that the WAE is no longer responding to it, the router stops sending requests to the WAE. This is transparent to users. If other WAEs are attached to the router, the router continues sending requests to the other WAEs.

When you remove a WAE, the pages that were cached on that device are no longer available to the router or other WAEs. You might see an increase in outgoing web traffic that might have otherwise been fulfilled by the WAE that you are removing. However, after a time, the router and other WAEs redistribute the load of web traffic.

Statement 1

Statement 1040

OL-6831-02

Chapter 3 Installing the Wide Area Application Engine

If you remove the last WAE from your network, you can also disable WAE support on the router. However, this action is not necessary because leaving WAE support enabled when there are no WAEs attached has no effect on the router’s performance.

To replace a WAE, remove it from the network, and then install a new WAE and configure it using the same configuration parameters (IP address, and so forth) that you used for the removed WAE.

(Personal System/2 [PS/2] or Universal Serial Bus [USB]) for Linux and ACNS software troubleshooting. However, the keyboard and mouse are supported by the BIOS for power-on self-test (POST) and diagnostic programs that are located in the device ROM.

When console redirection is enabled, all the tests available from a keyboard are accessible through the console connection as well. (Mouse support, however, is not available through the console connection.)

You can run all the diagnostics and tests that are supported by the BIOS, with a few exceptions. Tests for a disk drive, for example, are invalid because the device does not include a disk drive in the hardware configuration.

Tests for peripheral devices (such as mouse, keyboard, and monitor) and ports (such as the USB port) that are not supported by ACNS software are also invalid.

Caution Customer-replaceable components include the Fibre Channel adapter and hard

disk drives. All other components that are not orderable as spare hardware options can only be replaced by a qualified service technician. Once you have identified a faulty component, contact Cisco Technical Support. (See the “Obtaining

Documentation” section on page xvii.)

Step 3 Set all display controls on the terminal or display device to the middle position.

Step 4 Power up all external devices.

Step 5 Power up the device.

Step 6 Record any POST error messages that are displayed on the screen. If an error is

displayed, look up the first error in the “POST Error Codes” section on page 5-52.

Step 7 Check the system error LED on the front panel (see Figure 1-2); if it is on, see the

“System Error LED and the Diagnostic Panel LEDs” section on page 5-33.

Step 8 Check the system error log. If an error was recorded by the system, see the

“Symptoms and Solutions” section on page 5-28.

Step 9 Start the diagnostic programs and check for the following responses:

• One beep

• Readable instructions or the main menu

Step 10 Take one of the following actions:

• If you received both responses, run the diagnostic programs. For information

on how to use the diagnostic programs, see the “Using the System Diagnostic

Programs” section on page 5-5.

Identifying System Problems

If the diagnostic programs were completed successfully and you still suspect a problem, see the “Undetermined Problems” section on page 5-25.

• If you did not receive both responses, find the failure symptom in the

“Symptoms and Solutions” section on page 5-28.

Checking Connections and Switches

Improperly set switches and controls and loose or improperly connected cables are the most likely source of problems for the chassis or other external equipment. A quick check of all the switches, controls, and cable connections can easily solve these problems. (See Figure 1-2 for the location of front panel controls and indicators. See Figure 1-3 for the location of back panel connectors on the system.)

Chapter 5 Troubleshooting the System Hardware

Using the System Diagnostic Programs

The device diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the following major components of the device: the system board, Ethernet controller, RAM, serial ports, and hard disk drives. You can also use the diagnostic programs to test some external devices. See the “Diagnostic Programs

and Error Messages” section on page 5-7.

If you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

When troubleshooting, note the following points:

• If multiple error codes are displayed, diagnose the first error code that is

displayed.

• If the computer stops with a POST error, go to the “POST Error Codes”

section on page 5-52.

• If the computer stops and no error message is displayed, go to the

“Undetermined Problems” section on page 5-25.

• For power supply problems, see the “Power Supply LED Errors” section on

page 5-50.

• For safety information, see Chapter 2, “Preparing to Install the Wide Area

Application Engine.”

• For intermittent problems, check the error log.

Diagnostic Tools Overview

The following tools are available to help you identify and resolve hardware-related problems:

• POST beep codes and error messages

Cisco Wide Area Application Engine 7326 Hardware Installation Guide

OL-6831-02

5-5

Using the System Diagnostic Programs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. See the next section, “POST,” for more information.

• Error log

The POST error log contains the three most recent error codes and messages that the system has generated during POST. The system error log contains all the error messages that were issued during POST.

• SCSI error messages

For information on SCSI errors, see the “SCSI Errors” section on page 5-60.

• Diagnostic programs and error messages

The device diagnostic programs are stored in ROM on the system board. These programs are the primary method of testing the major components of your device. See the “Diagnostic Programs and Error Messages” section on

page 5-7 for more information.

• Light Path Diagnostics

Your device has LEDs to help you identify problems with device components. These LEDs are part of the Light Path Diagnostics that are built into your device. By following the path of LEDs, you can quickly identify the type of system error that occurred. See the “Using Light Path Diagnostics” section on

page 5-21 for more information.

• Error symptom charts

These charts list problem symptoms, along with suggested steps to correct the problems. See the “Error Symptoms” section on page 5-43 for more information.

Chapter 5 Troubleshooting the System Hardware

POST

5-6

When you power up the device, it performs a series of tests to check the operation of device components and some of the hardware options installed in the device. This series of tests is called the power-on self-test, or POST.

If POST finishes without detecting any problems, a single beep sounds, and the first screen of your operating system or application program appears.

Cisco Wide Area Application Engine 7326 Hardware Installation Guide

OL-6831-02

Chapter 5 Troubleshooting the System Hardware

If POST detects a problem, more than one beep sounds, and an error message appears on your screen. See the “Beep Symptoms” section on page 5-28 and

“POST Error Codes” section on page 5-52 for more information.

Note If you have a power-up password or administrator password set, you must enter

the password and press Enter when prompted, before POST will continue.

Note A single problem might cause several error messages. When this occurs, work to

correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time that you run the test.

The POST error log contains the three most recent error codes and messages that the system generated during POST. The system error log contains all messages issued during POST and all system status messages from the service processor.

You can view the contents of the system error log from the diagnostic programs.

Using the System Diagnostic Programs

Diagnostic Programs and Error Messages

The device diagnostic programs are stored in upgradable ROM on the system board. These programs are the primary method of testing the major components of your device.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the device displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when the diagnostic programs are run.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where:

Function Name is the name of the function being tested when the error occurred. This corresponds to the function code (fff) shown in the error code format in the previous section.

Result can be one of the following:

• Passed—This result occurs when the diagnostic test is completed

without any errors.

5-8

• Failed—This result occurs when the diagnostic test discovers an error.

• User Aborted—This result occurs when you stop the diagnostic test

before it is complete.

• Not Applicable—This result occurs when you specify a diagnostic test

for a device that is not present.

• Aborted—This result occurs when the test could not proceed, for

example, because of the system configuration.

• Warning—This result occurs when a possible problem is reported

during the diagnostic test, such as when a device driver is not found.

• Test-specific string—This is additional information that you can use to

analyze the problem.

Chapter 5 Troubleshooting the System Hardware

Note If diagnostic error messages appear that are not listed in the tables, make sure that

your device has the latest levels of BIOS and diagnostics microcode installed.

Checking the Power Subsystem

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition.

To perform a general procedure for troubleshooting power problems, follow these steps:

Step 1 Power down the device and disconnect all AC power cords.

Step 2 Check for loose cables in the power subsystem. Also check for short circuits, for

example, if there is a loose screw causing a short circuit on a circuit board.

Step 3 Remove adapters and disconnect the cables and power connectors to all internal

and external devices until the device is at the minimum configuration required to start it.

Step 4 Reconnect all AC power cords and power up the device. If the device starts up

successfully, replace adapters and devices one at a time until the problem is isolated. If the device does not start up from the minimal configuration, replace components of a minimal configuration one at a time until the problem is isolated.

Checking the Power Subsystem

Chapter 5 Troubleshooting the System Hardware

Troubleshooting the Ethernet Controller

Note The following are the minimum operating requirements:

• One power supply

• Power cage assembly

• System board

• One microprocessor and voltage regulator module (VRM)

• Memory module (with a minimum of two 128-MB DIMMs)

Troubleshooting the Ethernet Controller

This section provides troubleshooting information for problems that might occur with the 10/100/1000-Mbps Ethernet controller.

Network Connection Problems

If the Ethernet controller cannot connect to the network, check the following conditions:

• Make sure that the cable is installed correctly.

The network cable must be securely attached at all connections. If the cable is attached but the problem remains, try a different cable.

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps, you must use Category 5 or higher cabling.

• Determine whether the hub supports autonegotiation. If it does not, try

configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.

• Check the Ethernet controller LEDs on the device back panel. (See

Figure 1-3.)
