Chapter 4 Installing Hardware Options for the WAVE-594 and WAVE-694

Replacing a Fan

Step 4 Within one minute, insert the new drive into the same slot by aligning the replacement drive assembly with guide rails in the bay and sliding the drive assembly into the bay until it stops. Make sure that the drive is properly seated in the bay.

Step 5 Close the drive handle.

Step 6 Check the hard disk drive status LED after the system has booted to verify that the hard disk drive is operating correctly. If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed.

Step 7 Wait 1 minute and then verify that the replaced disk drive is in the Rebuilding state by using the show disks details command in EXEC mode.

Note The system automatically starts the rebuild operation when it detects the removal and reinsertion of a drive that is part of the logical RAID drive.

Step 8 Wait until the rebuild operation is complete. A disk rebuild operation may take several hours. You can check if the rebuild operation is complete by using the show disk details command in EXEC mode. The physical drive state will be Online and the RAID logical drive state will be Okay after the rebuild operation is completed.

Step 9 Use the show disk tech command in EXEC mode to verify that the firmware and BIOS information is correct for both hard drives.

If you have multiple disk failures and your RAID-1 logical status is Offline, you must recreate the RAID-1 array. For more information on disk removal and replacement procedures, see the Cisco Wide Area Application Services Configuration Guide chapter named “Maintaining Your WAAS System.”

Replacing a Fan

The WAVE appliance supports six fan assemblies that are hot-swappable.

Fan assemblies can only be inserted in one orientation.

Note Fan assemblies must be inserted and can only function with the surface marked “TOP” facing up.

Caution To maintain proper system cooling, do not operate the appliance for more than 1 minute without a fan installed in each bay.

To replace a fan assembly, follow these steps:

Step 1 Review the information in the “Safety Warnings and Cautions” section on page 2-1and the “Safety Guidelines” section on page 2-2.

Step 2 Disengage the fan latch and pull the fan out by the handle (see Figure 4-3).

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.
