Appendix B Maintaining the WAVE-594 and WAVE-694

Using Power Protection Devices

Power Source Interruptions

Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, power cables should always be properly grounded and one or both of the following methods should be used:

Use one of the power protection devices described in the “Using Power Protection Devices” section on page B-5.

Place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following:

Copier machines

Air conditioners

Vacuum cleaners

Space heaters

Power tools

Teletype machines

Adding machines

Laser printers

Facsimile machines

Any other motorized equipment

Besides these appliances, the greatest threats to a system’s supply of power are surges or blackouts caused by electrical storms. Whenever possible, turn off the system and any peripherals and unplug them from their power sources during thunderstorms.

If a blackout occurs—even a temporary one—while the system is turned on, turn off the system immediately and disconnect it from the electrical outlet. Leaving the system on may cause problems when the power is restored; all other appliances left on in the area can create large voltage spikes that can damage the system.

Using Power Protection Devices

A number of devices are available that protect against power problems such as power surges, transients, and power failures. The following subsections describe some of these devices:

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.
