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.
Professionally tested. Factory reset. Backed by 25+ years of enterprise trust.
This refurbished Cisco C9300-NM-8X is an 8-port 10G SFP+ network module designed as an optional uplink expansion for the Cisco Catalyst 9300 Series switches. Every unit is professionally tested, reset to factory defaults, and inspected through WhaleyComm's ISO 9001-certified process before it ships. At $399, this is a high-confidence path to expanding your Catalyst 9300 uplink capacity without the new-unit price tag.The C9300-NM-8X installs into the front-panel network module slot of compatible Catalyst 9300 switches and delivers 8 x 10 Gigabit Ethernet SFP+ uplink ports with backward compatibility for 1G SFP optics. All 8 ports operate simultaneously and are auto-discovered by Cisco IOS XE on insertion — no additional licensing or software upgrades required. The module is hot-swappable, meaning installation or replacement does not require powering down the switch or interrupting live traffic. Interface ports are designated TenGigabitEthernet1/1/1 through TenGigabitEthernet1/1/8 in IOS XE regardless of operating speed.
For organizations looking to scale campus aggregation, strengthen uplink density, or migrate from lower-speed interfaces without service disruption, the C9300-NM-8X delivers enterprise-grade performance at a fraction of new list pricing. WhaleyComm has served 5,000+ enterprise customers over 25+ years — when we ship a unit, it works.

Ideal Use Cases
Campus Aggregation Uplink Expansion
Add 8 x 10G SFP+ uplinks to a Catalyst 9300 switch to handle higher-density aggregation traffic across campus distribution layers — without replacing the host switch or disrupting live traffic.
Data Center Edge Connectivity
Connect Catalyst 9300 access switches to data center core or top-of-rack switches over 10G fiber using SR, LR, or other supported SFP+ transceivers, delivering high throughput at the network edge.
Server Farm Uplink Density
Provide dedicated 10G uplinks to high-performance servers or virtualization hosts, eliminating bottlenecks caused by lower-speed built-in uplinks on the base switch chassis.
Live Module Replacement or Hot-Swap Maintenance
Replace a failed or aging network module in an active Catalyst 9300 switch without powering down the chassis, preserving uptime in production environments where maintenance windows are limited.
Gradual 10G Migration from 1G Infrastructure
Use the C9300-NM-8X's backward compatibility with 1G SFP optics to migrate incrementally — running a mix of 1G and 10G connections simultaneously while transitioning the broader network at your own pace.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
No. The C9300-NM-8X does not require any additional licensing. Cisco IOS XE auto-discovers the ports on insertion and brings them up without manual configuration or software upgrades.
Yes. The C9300-NM-8X is hot-swappable, meaning it can be inserted or removed from a live switch without powering down the chassis or interrupting traffic on other ports. Always follow proper ESD precautions during handling.
Yes. The C9300-NM-8X is backward compatible with 1G SFP optics. All ports default to 10G and are designated as TenGigabitEthernet interfaces in IOS XE, even when operating at 1G speeds. This allows mixed-speed deployments on the same module.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
