Installing the DFC3 Daughter Card

Installing the DFC3 Daughter Card on Modules Equipped with a Stiffener Bracket

Note Some early versions of the WS-X6748-GE-TX Ethernet modules have a stiffener bracket mounted across the top front part of the module, which requires a modified procedure to install the DFC daughter card.

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

To install the DFC daughter card on a WS-X6748-GE-TX Ethernet module that is equipped with a stiffener bracket, follow these steps:

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 “Attaching Your ESD Grounding Strap” section on page 40 for instructions.)

Step 2 Remove the new DFC3 daughter card from the antistatic bag and the installation hardware from the bag.

Note The DFC3 daughter card is designed to be installed on different modules; therefore, there may be more mounting holes on the DFC3 daughter card than there are standoffs on the module. Not all mounting holes on the DFC3 daughter card will be used in all installations. Visually verify that there are standoffs beneath the mounting holes before installing the securing screws.

Step 3 Position the DFC3 daughter card over the module, and slightly tilt the DFC3 daughter card so that the back end will clear the module connectors.

Step 4 Carefully slide the DFC3 under the two stiffener bracket tabs. (See Figure 20.) Verify that the DFC daughter card is under the two stiffener bracket tabs.

Caution You must position the DFC daughter card under the two stiffener bracket tabs. If you install the DFC daughter card above the two stiffener bracket tabs, you can permanently damage the DFC daughter card.

Step 5 Align the mounting holes on the DFC3 daughter card with the male standoffs on the module. (See Figure 20.) Make sure that the remaining mounting holes on the DFC3 daughter card are aligned with the remaining standoffs.

Note You should visually verify that there are standoffs beneath the mounting holes before installing the securing screws.

Step 6 Press down on the edge of the DFC3 daughter card (see Figure 20) to seat the DFC3 daughter card power connector to the module power connector.

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.
