Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Cisco C9300-NM-8-10G is an 8-port 10 Gigabit Ethernet expansion network module engineered specifically for the Cisco Catalyst 9300 Series modular switches. By slotting into the dedicated network module bay, it dramatically increases uplink density and aggregate bandwidth, making it an ideal solution for enterprises that need to scale their core or distribution layer connectivity without deploying additional chassis.This Refurbished module provides eight SFP+ ports capable of operating at 10GE speeds, enabling high-throughput connections to servers, storage systems, or upstream aggregation switches. It integrates seamlessly with Cisco IOS XE software, preserving access to advanced features such as QoS, security policies, and network programmability that are native to the Catalyst 9300 platform.
Sourced as a Refurbished unit and fully tested prior to shipment by WhaleyComm, the C9300-NM-8-10G offers significant cost savings compared to new pricing while maintaining the reliability expected of enterprise-grade Cisco hardware. It is an excellent choice for organizations looking to maximize the value of existing Catalyst 9300 investments, refresh aging uplink infrastructure, or deploy additional switching capacity in budget-conscious environments.
Whether you are expanding a campus network, upgrading data center top-of-rack connectivity, or increasing inter-switch bandwidth, the C9300-NM-8-10G delivers the port density and speed necessary to keep pace with growing traffic demands.

Ideal Use Cases
Campus Distribution Layer Uplink Expansion
Organizations running Cisco Catalyst 9300 modular switches at the distribution layer can use this module to add eight additional 10GE uplinks, reducing bottlenecks between access and core layers. This is especially valuable in high-density wireless or IP telephony environments where bandwidth demand continues to grow.
Data Center Server and Storage Connectivity
The eight SFP+ ports allow direct 10GE connections to servers, NAS devices, or storage arrays, consolidating rack-level connectivity onto an existing Catalyst 9300 switch. This eliminates the need for a separate top-of-rack switch and simplifies cable management in smaller data center footprints.
Budget-Conscious Network Refresh
IT teams tasked with upgrading aging uplink infrastructure while managing capital expenditure can leverage this Refurbished module to increase port density at a fraction of new-unit pricing. It delivers enterprise-grade 10GE performance within the familiar Cisco IOS XE management environment already in use.

Compatibility Details
Review supported optics, cables, software, management protocols, and environment-specific compatibility guidance.
✓
The C9300-NM-8-10G is compatible with Cisco Catalyst 9300 Series switches that feature a dedicated network module slot, including modular SKUs such as the C9300-24UX, C9300-48UXM, C9300-48UN, and other NM-capable variants [Verify full model list]. It is not compatible with fixed-configuration Catalyst 9300 models that do not include a network module bay.
✓
Software compatibility requires Cisco IOS XE; consult Cisco's official release notes to confirm the minimum recommended IOS XE version for your specific deployment. Transceiver compatibility follows Cisco's SFP+ specification for 10GE optics (e.g., SFP-10G-SR, SFP-10G-LR) [Verify supported transceiver list with Cisco compatibility matrix].

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
This module is designed for Cisco Catalyst 9300 Series switches that include a dedicated network module expansion slot. Fixed-configuration Catalyst 9300 models without a module bay are not compatible; verify your specific switch SKU supports a network module before ordering.
The C9300-NM-8-10G uses SFP+ form-factor transceivers for 10 Gigabit Ethernet connectivity. Compatible Cisco SFP+ optics such as SFP-10G-SR (short range) or SFP-10G-LR (long range) are required and are not included with the module.
Refurbished means this module has been previously deployed and has since been professionally inspected, tested, and verified to meet functional specifications by WhaleyComm prior to resale. It offers the same core performance as a new unit at a reduced price point.
Basic port functionality on the C9300-NM-8-10G operates under the existing IOS XE software running on the host Catalyst 9300 switch. However, advanced feature licenses (such as DNA Advantage or DNA Essentials) may be required depending on the specific capabilities you intend to use; consult Cisco's licensing documentation for your deployment scenario.
