Step 6 When the SODIMM is installed, check the two alignment holes, and ensure that the spring retainer is visible. If it is not, the SODIMM is not seated properly. If any SODIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SODIMM firmly back into the socket until the retainer springs snap into place.

Installing the DFC3 Daughter Card

This section contains two DFC3 installation procedures. One procedure covers installing the DFC3 daughter card on modules that are not equipped with stiffener brackets. A second procedure is included that covers installing the DFC daughter cards on WS-X6748-GE-TX modules that are equipped with stiffener brackets.

Installing the DFC3 Daughter Card on Modules Without Stiffener Brackets

To install the DFC3 on modules that do not have stiffener brackets, 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 new DFC3 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 Align the mounting holes on the DFC3 daughter card (see Figure 14) with the male standoffs on the module. (See Figure 15.) Make sure that the remaining mounting holes on the DFC3 daughter card are aligned with the remaining standoffs on the module.

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.
