The Cisco Catalyst 9200 Series switch supports dual field-replaceable power supplies. Each switch is shipped with one power supply; a second identical unit can be ordered together with the switch or added later. The optional second power supply can be used to provide redundancy or to supply additional power for PoE+ ports when required.

Advantages

Dual field-replaceable power supplies enable higher availability through power redundancy and allow scalable PoE+ capacity without replacing the main unit. The ability to add the second power supply later provides deployment flexibility and helps match power capacity to changing needs.

Key specifications

• Compatibility: Cisco Catalyst 9200 Series switches
• Configuration: Single power supply included; second identical unit optional
• Function: Redundancy and additional PoE+ power
• Field-replaceable: Yes

How to use

Install the default power supply provided with the switch and connect it to a suitable AC source. If greater availability or additional PoE+ capacity is required, install the optional identical power supply in the spare power bay and connect it to power. The switch will use the supplies to provide redundant power or to aggregate available wattage for PoE+ ports according to the platform's power management rules.

Recommendations

For installations requiring uninterrupted operation, add the second power supply during initial deployment or keep a spare on hand to reduce downtime. Verify PoE+ power budgets for your specific Catalyst 9200 model to ensure the combined supplies meet the expected load.
