Cisco Catalyst C9300-NM-2Y 

Network Modules

Cisco Catalyst 9300 Series switches (C9300X and C9300 SKUs) support optional network modules for uplink ports. These modules offer flexibility for uplink speeds ranging from 1G to 40G, including multigigabit options for high-performance environments. The default switch configuration does not include the network module.

Power supplies

The Cisco C9300-NM-2Y is a network module designed for the Catalyst 9300 Series switches, specifically offering 2 x 25G SFP28 uplink ports. It doesn’t have its own power supply—instead, it relies on the switch chassis it’s installed in.

Note:

• You can install one or two power supply modules in the switch.
• If only one is installed, the second slot should be covered with a blank plate.
• Power stacking is supported via StackPower, allowing switches to share power across the stack.

Stacking

The NM-2Y module is not used for stacking, but for uplink connectivity to other network devices. Stacking is handled via dedicated StackWise ports on the Catalyst 9300 switches and not through the NM-2Y module.

If you’re planning a deployment and want both stacking and high-speed uplinks, you’ll typically:

• Use StackWise ports for stacking.
• Use C9300-NM-2Y for uplinks to aggregation or core switches.

Fan

Cisco Catalyst 9300 Series switches also come with three field-replaceable fans and support (N+1) redundancy.

Fan Module Details for Catalyst 9300 Series

• The C9300 series switches, including those using the C9300-NM-2Y module, come with three field-replaceable fan modules.
• These fans support N+1 redundancy, meaning the system can tolerate one fan failure without impacting performance.
• The standard fan module part number is FAN-T2=, which is compatible across various Catalyst 9300 model

Security

Security Features of C9300-NM-2Y

• Built for Secure Networking: The 9300 Series is Cisco’s lead stackable platform for secure access, supporting Software-Defined Access (SD-Access), which enables policy-based automation and segmentation.
• Trustworthy Hardware: Includes Secure Boot Ensures that only trusted software is loaded during startup, preventing unauthorized firmware or software from compromising the system and image signing, ensuring only trusted software runs on the device.
• MACsec Encryption: Supports IEEE 802.1AE MACsec, providing line-rate Layer 2 encryption for secure data transmission.
• Advanced Threat Protection: Integrates with Cisco DNA Center and Cisco Identity Services Engine (ISE) for dynamic policy enforcement and threat containment.
• Network Visibility: Offers Encrypted Traffic Analytics (ETA) to detect malware in encrypted traffic without decryption.
• ACL and QoS Scaling: Supports up to 5120 ACL entries, allowing granular traffic control and prioritization

Resiliency and high availability

Resiliency Features

• Cisco StackWise® Technology: Supports stacking of up to 8 switches with sub-50-ms failover, enabling seamless redundancy and simplified management.
• Stateful Switchover (SSO): When stacked, switches can perform nonstop forwarding during a failover event, preserving sessions and minimizing downtime.
• Cisco StackPower: Allows power sharing and redundancy across the stack, ensuring uninterrupted operation even if one power supply fails.
• Modular Uplinks: Offers flexibility and redundancy in uplink configurations, helping maintain connectivity during link failures.

High Availability Capabilities

• Cisco IOS XE Operating System: A modern, modular OS that supports hot patching and advanced programmability, reducing the need for disruptive reboots.
• UADP 2.0 Architecture: Enables high throughput and scalability, ensuring the switch can handle demanding workloads without performance degradation.
• Advanced QoS and Traffic Management: Intelligent services like granular bandwidth control and traffic prioritization ensure consistent performance even under load
