Removing the DFC3 Daughter Card

Removing the DFC3 Daughter Card from Modules Without Stiffener Brackets

To remove the DFC3 daughter card from modules that are not equipped with a stiffener bracket, follow these steps:

Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94

Step 1 Attach an ESD grounding strap to your wrist and to ground. (If you are unsure about the correct way to attach an ESD grounding strap, refer tothe “Attaching Your ESD Grounding Strap” section on page 40 for instructions.)

Step 2 Remove the Ethernet module from the Catalyst 6500 series switch. (If you are unsure about the correct procedure for removing a module from the switch chassis, refer to the “Removing and Installing Modules in the Chassis” section on page 32 for removal instructions.)

Step 3 Place the Ethernet module on an antistatic mat with the front of the module facing toward you.

Step 4 If your DFC daughter card has a small metal installation bracket as shown in Figure 3, use a No.1 Phillips-head screwdriver to remove the two cap nuts and the one screw securing the bracket. Set them aside with the bracket. If there is no bracket, just remove the two cap nuts and the one screw.

Step 5 Remove the remaining securing screws. (See Figure 3.)

DFC3A, DFC3BXL, DFC3B specifications

Cisco Systems, a leader in networking and communication technology, has developed various products to enhance the performance and efficiency of network systems. Among these products, the Distributed Forwarding Card series stands out, particularly the DFC3BXL, DFC3B, and DFC3A. These cards are designed to provide advanced data forwarding capabilities in high-performance networking environments.

The DFC3BXL is a high-end forwarding card that supports advanced hardware-based packet forwarding, ensuring minimal latency and maximum throughput. With a forwarding capacity of up to 40 Gbps, it is well-suited for large enterprise networks that require fast and reliable data processing. One of its significant features includes support for load balancing across multiple ports, enhancing the network's efficiency and resilience.

The DFC3B, on the other hand, offers a balanced combination of performance and cost. With a forwarding capacity of 32 Gbps, it is ideal for medium-sized networks looking for reliable performance without the higher price tag associated with the DFC3BXL. It also supports advanced Quality of Service (QoS) features, enabling administrators to prioritize critical applications and manage bandwidth effectively.

Lastly, the DFC3A serves as an entry-level option for organizations that need basic forwarding capabilities. With a maximum forwarding capacity of 16 Gbps, it is suitable for smaller networks or branch offices. Despite being an entry-level card, it still offers essential features such as support for standard networking protocols and basic QoS capabilities.

All three cards leverage Cisco's robust architecture, providing high reliability and fault tolerance. They are designed to be easily integrated into existing Cisco devices, allowing for seamless upgrades and expansions. Additionally, these forwarding cards feature built-in telemetry and diagnostics tools, enabling network administrators to monitor performance in real-time and quickly address potential issues.

Technologically, all three cards utilize Cisco’s innovative ASICs (Application-Specific Integrated Circuits), designed to optimize packet processing. This ensures that packet forwarding remains efficient even under heavy network load conditions.

In summary, Cisco's DFC3BXL, DFC3B, and DFC3A Distributed Forwarding Cards cater to varying needs within enterprise networks, from high-end performance to basic functionality. Their advanced features, coupled with Cisco's proven reliability, make them an excellent choice for organizations looking to enhance their network infrastructure.
