Power supply Cisco C9K-PWR-1600WAC-R

The Cisco C9K-PWR-1600WAC-R is a 1600W AC power supply engineered for use with Catalyst 9500 series switches. Designed to deliver consistent electrical power in enterprise and data center environments, this power supply helps maintain switch uptime and supports high-availability networking setups. Its compact form and standard AC input make it compatible with typical rack-mounted installations where stable, high-capacity power delivery is required.

Advantages

This 1600W AC unit provides high continuous output capacity suitable for densely populated switch line cards and feature-rich configurations. Built to meet Cisco hardware compatibility requirements for Catalyst 9500 systems, it contributes to system redundancy and load sharing when used in multi-supply installations. The design supports standard AC mains input and includes features intended to reduce thermal stress and improve electrical stability during varying load conditions.

Suitable for

• Powering Catalyst 9500 series switches in enterprise campus and data center networks
• Redundant power configurations to increase service availability
• High-density port and module deployments requiring sustained power delivery
• Racks and enclosures with standard AC power infrastructure

Key specifications

• Output power: 1600 watts continuous
• Input: AC mains compatibility (standard rack power environments)
• Form factor: Hot-swappable, rack-compatible power module
• Cooling: Designed for forced-air cooling within switch chassis
• Compatibility: Designed for Catalyst 9500 series platform

How to use

Install the power supply into the designated bay on a Catalyst 9500 series switch while the chassis is powered down, or follow the device-specific hot-swap procedure if supported. Ensure the unit is fully seated and secured according to the switch hardware instructions. Connect the AC mains cable to a properly rated outlet or power distribution unit. Verify the switch recognizes the power module and monitor the system power status through the switch management interface or indicator LEDs.

Usage recommendations

Place the switch and power connections in an environment that meets the manufacturer's temperature and ventilation specifications. For redundancy, use multiple compatible power supplies and ensure power sources are on separate circuits where possible. Regularly inspect power cabling and chassis air paths for obstructions and replace any failed modules promptly to maintain continuous operation.
