Chapter 6 Troubleshooting the System Hardware

Checking Connections and Switches

Step 5 Power up the appliance.

Step 6 If the self-diagnostic programs were completed successfully and you still suspect a problem, see the “Undetermined Problems” section on page 6-4.

Step 7 Check the system error log to see if an error was recorded by the system.

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 1-1for the location of front panel controls and indicators. See Figure 1-3for the location of back panel connectors on the system.)

To check all the connections and switches, follow these steps:

Step 1 Power down the system. Disconnect all the power cables from their electrical outlets.

Step 2 If the system is connected to a power strip (or power distribution unit), turn the power strip off and then on again.

If the power strip is receiving power go to Step 5.

If the power strip is not receiving power go to Step 3.

Step 3 Plug the power strip into another electrical outlet.

If the power strip is receiving power, the original electrical outlet probably does not function. Use a different electrical outlet.

If the power strip is not receiving power go to Step 4.

Step 4 Plug a system that you know works into the electrical outlet.

If the system receives power, the power strip is probably not functioning properly. Use another power strip.

If the system does not receive power, go to Step 5.

Step 5 Reconnect the system to the electrical outlet or power strip.

Make sure that all connections fit tightly together.

Step 6 Power up the system.

If the problem is resolved, the connections were loose. You have fixed the problem.

If the problem is not resolved, call your customer service representative. (See the “Obtaining

Documentation and Submitting a Service Request” section on page xiv.)

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.

In terms of scalability, the WAVE594K9 is designed to grow with an organization’s needs. It can easily be integrated into existing IT infrastructures and expanded as traffic demands increase. This flexibility makes it an ideal solution for businesses of all sizes, from small enterprises to large corporations.

To summarize, the Cisco Systems WAVE594K9 is a powerful ADC that enhances application delivery through intelligent traffic management, application acceleration, built-in security features, and comprehensive monitoring tools. Its ability to scale effectively makes it a strategic investment for ensuring optimal application performance in today’s dynamic IT environments.
