Product overview
C9500-40X-E densifies fixed 10G on Catalyst 9500: forty SFP+ ports, up to 960 Gbps full-duplex, up to 720 Mpps, Non-PoE, StackWise Virtual, and PWR-C4-950WAC-R front-to-back cooling on authorized data.
Choose it when day-one 10G density needs far more than sixteen fixed ports. Stay on C9500-16X-E when sixteen ports plus a modular uplink cover the design.

Deployment role
- High-density fixed 10G core / aggregation
Deployment scenarios
Campus or aggregation cores lighting many 10G SFP+ links on one fixed switch.
Migrations consolidating multiple lower-density 10G platforms.
Enterprise campus core where uplink density is the primary constraint. Campus core or collapsed-core where northbound uplinks are the constraint.
Technical selection notes
Higher capacity follows the denser faceplate — do not treat Tbps as a reason to skip 16X if port count fits 16X.
Not recommended for
Not a 16-port fixed 10G faceplate.
Not a PoE closet switch.
Not a 100G/400G spine.
What to confirm on the quote
- Exact PID C9500-40X-E
- 10G optic types and lit count
- StackWise Virtual yes/no
- Airflow / PSU preference
- Quantity, destination, documentation
Related / alternative models
Same-brand family first, then same deployment role, then cross-brand equivalents when useful. Different power/optic technologies are labeled explicitly.
FAQ
How many 10G ports are listed?
40 × 10 Gbps SFP+.
What capacity is listed?
Up to 960 Gbps full-duplex and up to 720 Mpps.
When is 16X enough?
When about sixteen fixed 10G ports plus an NM cover day-one needs.
What PSU is listed?
PWR-C4-950WAC-R with front-to-back cooling language.
Is there a universal winner vs 16X?
No. Match port density and optic plan first.
What belongs on the RFQ?
Exact PID, optics, SV, airflow, quantity, destination.
