PRODUCT DESCRIPTION
Cisco 350W AC 80+ platinum Config 1 Power Supply Spare (PWR-C1-350WAC-P=) — Local Warranty
Spare 350W AC Supply for Catalyst 9300 Data Switches
The Cisco PWR-C1-350WAC-P= is the spare version of the 350W AC 80 Plus Platinum Config 1 power supply used in the Catalyst 9300 family. Cisco lists it as the default power supply for the data-only (non-PoE) models C9300-24T, C9300-48T, C9300L-24T-4G, C9300L-24T-4X, C9300L-48T-4G and C9300L-48T-4X.
Platinum-Rated Version of the 350W Module
The "-P" suffix identifies the 80 Plus Platinum-rated version of the PWR-C1 350W AC module, alongside Cisco's other Platinum-rated Config 1 supplies (PWR-C1-715WAC-P, PWR-C1-1100WAC-P and PWR-C1-1900WAC-P).
Hot-Swappable, Dual-Supply Capable
Catalyst 9300 switches run on one or two active power supply modules; the second bay holds either another supply or a blank cover. Cisco's installation guide states the power supply is hot-swappable. In some configurations, such as full PoE+ or power-sharing mode, removing a supply can cause powered devices to shut down until the power budget re-balances, so plan replacement accordingly.
Mixing Supplies in One Switch
Cisco states that a mix of power supply modules (Platinum-certified, Titanium-certified or non-certified) is supported within a switch. This lets you add the PWR-C1-350WAC-P as a second, redundant supply in a switch that already has a 350W module, or use it as a like-for-like replacement.
Simple Status LEDs
Two LEDs on the module show status at a glance: AC OK (green when AC input power is present) and PS OK (green when power output to the switch is active). A power cord retainer helps keep the cord secured in the rack.

Compatibility & Software Support
Compatible Switches
Cisco's Catalyst 9300 data sheet and hardware installation guide list the PWR-C1-350WAC-P as the default supply for the C9300-24T, C9300-48T, C9300L-24T-4G, C9300L-24T-4X, C9300L-48T-4G and C9300L-48T-4X. PoE models (for example C9300-24P/48P and C9300L-24P/48P) ship with higher-rated 715W or 1100W supplies to meet their PoE budget, and Catalyst 9300LM models use the separate PWR-C6 supply range. Cisco does not list this 350W module for any Catalyst 9300X model.
Redundancy and Hot-Swap
With two supplies installed, a single supply can be replaced while the switch stays up, subject to the power budget. Cisco notes that in full PoE+ or power-sharing configurations, removing a supply may temporarily shut down powered devices until budgets re-balance; hot-swapping is recommended when the switch is in StackPower mode with sufficient power available.
Lifecycle Status
As of October 2026, Cisco's Catalyst 9300 Series End-of-Life notice listing does not include an End-of-Sale notice for the PWR-C1-350WAC-P.
Warranty
Local Singapore warranty. For warranty claims, keep your SourceIT invoice as proof of purchase.

Is it hot-swappable?
Yes. Cisco states the Catalyst 9300 power supply is hot-swappable, though in full PoE+ or power-sharing configurations removing a supply may briefly affect powered devices.
Can I mix it with a 715W or non-Platinum supply in the same switch?
Cisco states that a mix of Platinum-certified, Titanium-certified and non-certified power supply modules is supported in a switch.
Is 350W enough for a PoE switch?
Cisco ships PoE models with 715W or 1100W supplies to meet their PoE budgets. The 350W module is the default for data-only models.
What is the operating temperature range?
Cisco specifies -5 to 45°C (23 to 113°F) at altitudes up to 5,000 ft for the power supplies.
