PWR-C1-715WAC-P

The PWR‑C1‑715WAC‑P is a 715‑watt, AC, Platinum‑rated power module (power supply) made by Cisco. It is used in Cisco Catalyst 9300 series switches (also compatible with C9300L) and other Cisco devices that accept the C1 AC power module format. The “‑P” suffix indicates it’s Platinum-rated, meaning higher efficiency and better performance under typical loads. This power adapter is designed as a plug-in module that fits perfectly in compatible Cisco Catalyst 9300 Series switches. It delivers a 715-watt redundant power supply at AC 100-240 V for user convenience and high-performance. 1,054,881 (ranges from 1.05M to 2.6M depending on temperature, input voltage and vendor).

Features

• High Maximum Power (715 W AC)Provides up to 715 watts of power output, sufficient to support many PoE/PoE+ devices on a Catalyst 9300 switch without overloading the PSU
• High efficiency (Platinum): Less wasted energy, less heat generated, better for power cost savings especially in large deployments.
• Good environmental tolerance: Usable in typical data‑center / wiring‑closet settings, even at moderate altitude and temperature.
• Platinum Efficiency Rating: It is “‑P” for Platinum. Higher efficiency means less wasted power (heat), lower operating costs, and better performance in high‑density or heat‑sensitive environment
• Wide AC Input Voltage Range: Works with 100‑240 VAC, 50‑60 Hz. This gives flexibility for use in many countries / environments without needing special power arrangements
• Good Output Ratings: Delivers ‑56 V at up to ~12.8 A. This voltage/current level is typical for powering internal and PoE circuitry reliably
• Holdup Time / Power Stability: Minimum ~16.7‑20 ms retention at 100 VAC input. That means that during very brief drops in input power, it can keep supplying output long enough to avoid immediate failure/disruption.
• Hot‑Swappable / Redundancy Capable: Can be replaced without powering down (depending on switch configuration), supports redundant PSU setups. Useful for high‑availability network setups.
• LED Indicators: Has “AC OK” (input power status) and “PS OK” (output status) LEDs. Simple way to check operational health without tools
• Compact / Rugged Form Factor: Dimensions and weight (~1.58 × 3.25 × 12.20 in; ~1.2 kg / 2.6‑2.8 lb) make it manageable in space‑constrained racks; designed for heat/range of operating conditions.
• Environmental Tolerance: Operates in ambient temps from about ‑5 °C to +45 °C under typical altitude; storage down to ‑40 °C to +70 °C. Also supports both moderate altitude (e.g. up to ~3,000 m) and variations in humidity (non‑condensing).
• Certifications / EMC / EMI Compliance: Meets international standards for safety, electromagnetic compatibility, etc. Helps with regulatory compliance in asset deployments.

Compatibility & Use Cases

• Designed for Cisco Catalyst 9300 Series (and compatible with other Cisco switches that take the same form‑factor power module).
• For switches with PoE/PoE+ where you need significant power budget, this higher wattage PSU helps in feeding many powered devices (phones, APs, cameras etc.) without overloading.
• Hot‑pluggable/ redundant power configurations: many enterprise switch deployments use dual PSUs so that if one fails, the other can carry the load (or at least keep critical services running). The hot‑swap nature of the PSU helps with this.

Things to Watch Out For

• Power budget vs load: Even with 715W, if you have many PoE/UPoE devices you need to check the total draw, especially at peak/boot time.
• Holdup time: Minimum output hold‑up time spec (how long it maintains output during short AC dips) matters. For 715W AC version it’s around 16.7 ms at 100 VAC.
• Operating altitude & temperature: At higher altitudes or higher ambient temps performance or allowable loads may be reduced. Check how your deployment environment matches the spec.
• Efficiency and heat: Being Platinum rated means less wasted energy & less heat, but still a high‑wattage PSU generates significant heat; make sure your switch enclosure has proper cooling.
