Cisco PWR-C5-1KWAC 1000W Power Supply 80 Plus Platinum for Catalyst 9200 Series 

The Cisco PWR-C5-1KWAC/2 is a 1000W AC power supply for Cisco Catalyst 9200 Series switches, providing 100-240 VAC input and supporting high-availability and high-performance network environments. You can find specific details such as input current, output ratings (54V at 16.5A), and holdup time in datasheets available on vendor sites. Model: PWR‑C5‑1KWAC (also seen as PWR‑C5‑1KWAC=) designed to delivers up to 1000 Watts AC power for Cisco Catalyst 9200 / 9200L switches, particularly useful when many ports require Power over Ethernet (PoE) or for high‑capacity deployments. Form‑factor: Hot‑plug/swappable “Config‑5” PSU module.

Features

• High capacity (1000 W): Enough to support full PoE loads and network operations in medium to large switch installations.
• Wide AC input range (100‑240 VAC, 50‑60 Hz): Good for global deployments and areas with varying supply voltages.
• Efficiency: This 1 kW AC PSU is in the “Platinum” category for efficiency at full load in many Cisco Catalyst 9200 models. That means high power conversion efficiency and less wasted heat.
• Holdup time: Minimum output holdup (holding power briefly during dips) is about 20 milliseconds at 100 VAC input. This helps tolerate short disturbances in power without resetting the switch.
• LED indicators: Usually two‑colour LEDs for status (e.g. “AC OK,” “PS OK”) so you can see if input and output are functioning.
• Redundancy: Catalyst 9200 series can use two of these PSUs in a switch for redundancy (or to share load, especially with heavy PoE usage). One PSU is enough for many setups, but dual PSUs give reliability and higher/guaranteed PoE power
• Hot‑plug module: Can be replaced or added without shutting down the switch, simplifying maintenance.
• Short hold‑up time: Minimum ~20 milliseconds at 100 VAC input, meaning small power interruptions are tolerated without resetting the system.
• Certifications & safety compliance: Meets a range of international standards (UL, IEC, FCC, CE, etc.), which is important for regulatory and operational safety.

Use / Compatibility Notes

• Compatible with Catalyst 9200 / 9200L models that accept the Config‑5 PSU.
• Be aware that some lower‑port or non‑PoE models may not need or support the full 1 kW, so check switch model and PSU slot.
• Correct cabling and power infrastructure needed: the PSU draws substantial current when supplying full load + PoE. Ensure the AC side (power cord, breaker, UPS) can handle ~12‑16.5 A. Also ensure ventilation is adequate.

• Useful in redundancy setups: you can install two PSUs so one can take over if the other fails, or share the load.

• Suitable where AC supply may fluctuate but needs to be stable — the wide input range helps.

• Requires adequate cooling and airflow because at full load it dissipates significant heat. Ambient temperature, altitude also matter.

Limitation

• Single PSU Limits Redundancy: Without a secondary PSU, power redundancy isn’t available, increasing risk of downtime in PSU failure.
• Compatibility: Only compatible with Cisco Catalyst 9200/9200L series supporting Config-5 PSU modules. Not universal across all Cisco devices.
• Power Output Cap: Limited to 1000 watts max. If your network’s PoE demand exceeds this, some devices may receive reduced power or lose connectivity.
• Heat Generation: At full load, it produces significant heat requiring good ventilation and cooling. Poor airflow can shorten lifespan or cause failures.
