Removing a CFC or DFC Daughter Card

These tools and supplies are required to remove and install the DFC3 daughter card:

•Antistatic mat or foam pad to support the removed module and an antistatic bag to store the removed Central Forwarding Card (CFC) or DFC daughter card

•Your own ESD-prevention equipment or the disposable grounding wrist strap included in the upgrade kit

•Number 1 Phillips-head screwdriver for the DFC daughter card installation hardware

Removing a CFC or DFC Daughter Card

If your module has either a CFC or a DFC daughter card installed, you must remove the daughter card before installing the new DFC daughter card. Two procedures are provided: See either the “Removing the CFC Daughter Card” section on page 10 or “Removing the DFC3 Daughter Card from Modules Without Stiffener Brackets” section on page 13.

Removing the CFC Daughter Card

To remove a CFC daughter card, 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 to the “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 Use a Phillips-head screwdriver to remove the three securing screws and the two cap nuts. (See Figure 1.)

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.
