We are providing specifications below to explain why you should consider purchasing the Cisco 36 Port Expansion Module Networking, including a general overview, performance specifications, relevant images, media files, and technical information about the N9K-X9636C-R compatibility.


The N9K-X9636C-R Cisco Buffer Line card is a 36 port expansion module designed for the Cisco Nexus 9500 series switches. Here are some key specifications of the module:

  • Port density: The N9K-X9636C-R provides 36 ports of 100 Gbps connectivity, allowing for high-speed data transfer and network traffic management. The module supports QSFP28 transceivers, which provide a range of options for connecting to different types of network equipment.
  • Buffer capacity: The line card has a large buffer capacity of 36 MB per port, which helps to prevent packet loss and improve overall network performance. The buffer capacity allows for efficient management of traffic bursts, reducing the likelihood of network congestion.
  • Switch fabric capacity: The N9K-X9636C-R is designed to work with the Cisco Nexus 9500 series switches, which have a high-capacity switch fabric capable of supporting up to 30 Tbps of throughput. This allows for high-speed data transfer and efficient network operations.
  • Latency: The line card has a low latency of less than 3 microseconds, making it ideal for real-time applications such as voice and video communication. The low latency ensures that data packets are transmitted quickly and efficiently, reducing delays and improving overall network performance.
  • Power consumption: The N9K-X9636C-R has a maximum power consumption of 650 watts, making it an energy-efficient option for high-performance network operations.
  • Management and control: The line card can be managed and controlled through the Cisco Nexus 9500 series switches, which provide a centralized interface for configuring and monitoring network traffic. The switches allow for real-time visibility into network performance, as well as the ability to configure network policies and troubleshoot issues as they arise.


The installation of the N9K-X9636C-R Cisco Buffer Line card involves the following steps:

  • Ensure compatibility: Before installing the line card, ensure that it is compatible with the Cisco Nexus 9500 series switch and the chassis that you are using. Check the technical specifications and ensure that the switch has sufficient power and cooling capacity to support the new line card.
  • Power off the switch: Power off the Cisco Nexus 9500 series switch and disconnect all power cables. Ensure that the switch is completely powered off and all LEDs are off before proceeding.
  • Install the line card: Locate the expansion module slot on the switch and remove the protective cover. Carefully insert the line card into the slot, making sure that the connectors are aligned properly. Press down firmly on the line card until it clicks into place.
  • Connect cables: Once the line card is securely installed, connect the network cables to the QSFP28 ports on the line card. Ensure that the cables are connected properly and securely.
  • Power on the switch: Reconnect all power cables to the switch and power it on. Wait for the switch to complete its startup sequence and verify that the line card is detected and functioning properly.
  • Configure the line card: Once the line card is installed and functioning properly, configure it according to your network requirements. Use the Cisco Nexus 9500 series switch management interface to configure the line card and set up any necessary network policies or protocols.
  • Test the line card: Test the line card and verify that it is operating properly. Run network tests and monitor the performance of the line card to ensure that it is meeting your network requirements.

Security Features

The N9K-X9636C-R Cisco Buffer Line card 36 Ports Expansion Module provides several security features that help ensure the security of data transmission and network infrastructure. Here are some of the key security features:

  • Access Control Lists (ACLs): The line card supports the use of ACLs, which allow administrators to define rules for controlling network access and traffic flow. ACLs can be used to limit access to specific resources, block certain types of traffic, and prevent unauthorized access to the network.
  • Port security: The line card supports port security features, which allow administrators to restrict access to specific ports on the switch. This helps to prevent unauthorized access to the network and protect against network attacks.
  • Network segmentation: The line card supports network segmentation features, which allow administrators to divide the network into smaller segments based on factors such as location, department, or function. This helps to prevent the spread of malware and other network attacks by containing them within a specific network segment.
  • Role-based access control (RBAC): The line card supports RBAC features, which allow administrators to assign different levels of access to different users based on their roles within the organization. This helps to ensure that users only have access to the resources and data that they need to perform their job functions.
  • Encryption: The line card supports encryption features, which help to ensure the confidentiality and integrity of data transmitted over the network. The line card supports various encryption protocols such as AES and SHA, which provide strong encryption and hashing capabilities.
  • Network monitoring: The line card supports network monitoring features, which allow administrators to monitor network traffic for suspicious activity and potential security breaches. Network monitoring can help to detect and respond to security threats in real-time, improving the overall security of the network.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

For all your expansion module needs, we've got you covered with high-performance devices that increase functional capability and ease business processes.

You can talk to any of our staff and consult on what would be the best way forward when getting an expansion module to complement and enhance existing infrastructure, meet your immediate and future needs.

We have hardware level 12 with firmware 3.0 or higher modules that allow for the installation of up to 14 expansion modules below the base module for resilient performance. Expansion modules connect to the base module using USB Type-A connectors. That's not all, we have hardware level 11 and lower that supports up to 9 expansion modules.

With an expansion module, you get additional cartridge storage as well as tape drive capacity. We have expansion modules that contain up to two drives and two power supplies.

Expansion modules will need a power supply only if you install a tape drive in it. A single power supply can actually power two drives. However, you can add a second power supply for redundancy purposes. Without a tape drive, the expansion module is powered via the USB cable connected to the base module.

Expansion modules require 2U rack space and will be shipped with the necessary mounting hardware used to secure it to the rack.
