Troubleshooting the System Hardware

This chapter provides basic troubleshooting information to help you identify some common problems that might occur with your WAVE-594 and WAVE-694.

This chapter contains the following sections:

Identifying System Problems, page 6-1

Checking Connections and Switches, page 6-2

Troubleshooting the Ethernet Controller, page 6-2

Undetermined Problems, page 6-4

Problem-Solving Tips, page 6-5

Error Symptoms, page 6-6

Use the information in this chapter to determine whether a problem originates with the hardware or the software. For further assistance, contact your Cisco customer service representative.

Note When console redirection is enabled (it is disabled by default), 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.)

Caution Customer-replaceable components include the WAVE Interface Modules, hard disk drives, power supply assemblies, fans, and memory. 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 the Cisco Technical Assistance Center (TAC).

Identifying System Problems

To identify system problems, follow these steps:

 

Step 1

Check the power LED.

 

Step 2

Check the system fault LED (see System fault LED, page 1-3). If the status is yellow, check for alarms

 

 

using the show alarms command.

 

Step 3

Power down the appliance and all external devices.

 

Step 4

Check all cables and power cords. (See the “Checking Connections and Switches” section on page 6-2.)

694, WAVE594K9 specifications

Cisco Systems WAVE594K9 is a state-of-the-art application delivery controller (ADC) that is designed to optimize the performance and availability of applications across a wide area network. As part of Cisco’s advanced networking solutions, the WAVE594K9 effectively enhances application delivery, ensuring a seamless user experience even under heavy traffic conditions.

One of the primary features of the WAVE594K9 is its ability to provide comprehensive traffic management. This device intelligently load balances incoming requests and distributes them across multiple servers. By optimizing resource allocation, it minimizes response times and maximizes throughput, which is particularly beneficial for organizations dealing with fluctuating traffic patterns.

The WAVE594K9 also excels in application acceleration. This is achieved through various optimization techniques, including compression and caching. By reducing the size of transmitted data and storing frequently accessed content closer to users, the WAVE594K9 significantly speeds up application delivery. As a result, businesses can ensure that their users experience minimal latency, even when accessing resource-intensive applications.

Security is another key characteristic of the WAVE594K9. It integrates advanced security features, such as application layer firewalls, SSL offload capabilities, and DDoS protection. These built-in security measures not only safeguard sensitive data but also improve performance by offloading decryption tasks from application servers, allowing them to focus on processing actual requests.

Moreover, the WAVE594K9 is equipped with robust monitoring and reporting tools. Administrators can gain real-time insights into application performance, user activity, and traffic patterns. This level of visibility enables proactive management and troubleshooting, which helps in identifying and resolving potential issues before they impact end-users.
