Questions & Answers
Which power supplies does the Catalyst 9500 use?
Standard Catalyst 9500 models use PWR-C4 650W AC modules, while 9500 high-performance models use 950W AC or DC modules (PWR-C4-950WAC-R and DC variants). Match the PSU to your exact switch SKU.
Are Catalyst 9500 power supplies hot-swappable?
Yes. The 9500 supports hot-swappable, field-replaceable power supplies, allowing replacement without service interruption in redundant configurations.
Does the Catalyst 9500 need two power supplies?
The switch operates on one, but as a core and aggregation platform it should always run 1+1 redundant supplies connected to independent power feeds.
What is the difference between -R and -F PSU SKUs?
The suffix indicates airflow direction: -R is front-to-back (port-side exhaust) and -F is back-to-front (port-side intake). Match PSU airflow to your fans and hot and cold aisle design.
Can I use DC power with the Catalyst 9500?
Yes. DC power supply options are available for high-performance 9500 models, and they are common in service-provider and industrial facilities with -48V DC plants.
Are 9500 and 9300 power supplies interchangeable?
No. The 9300 uses PWR-C1 modules and the 9500 uses PWR-C4 modules. The two families are not cross-compatible.
Why does PSU airflow direction matter?
Mismatched airflow recirculates hot air into the chassis, raising temperatures and risking thermal shutdown. All PSUs and fan trays in one chassis must share the same airflow direction.
Where can I buy genuine Catalyst 9500 PSUs?
ORM Systems stocks genuine PWR-C4 650W and 950W modules with warranty, verified compatibility, volume discounts, and fast worldwide shipping.
