Removing and Installing Modules in the Chassis

Step 4 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of substeps:

Horizontal slots

a.Position the module in the slot. (See Figure 23.) Make sure that you align the sides of the module carrier with the slot guides on each side of the slot.

b.Carefully slide the module into the slot until the EMI gasket along the top edge of the module makes contact with the module in the slot above it and both ejector levers have closed to approximately 45 degrees with respect to the module faceplate. (See Figure 24.)

c.Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create a small (0.040 inch [1 mm]) gap between the module’s EMI gasket and the module above it. (See Figure 24.)

Caution Do not press down too hard on the levers. They will bend and be damaged.

d.While gently pressing down, simultaneously close the left and right ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 25.)

Note Failure to fully seat the module in the backplane connector can result in error messages.

e.Tighten the two captive installation screws on the module.

Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.

f.Verify that the module STATUS LED is lit. Check the STATUS LED periodically. If the STATUS LED changes from orange to green, the module has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the module has not successfully completed the boot process and may have encountered an error.

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.
