Cisco C9400-PWR-3200DC | 3200W DC Power Supply, Hot-Swappable, -48V

Q: Which Catalyst 9400 chassis models are compatible with the C9400-PWR-3200DC?
A: The C9400-PWR-3200DC is compatible with Catalyst 9400 Series chassis including C9404R (4-slot), C9407R (7-slot), and C9410R (10-slot) models requiring high-capacity redundant DC power.

Q: Can I mix AC and DC power supplies in the same Catalyst 9400 chassis?
A: Yes, you can mix AC and DC power supplies in redundant configurations. In N+N mode, all active PSUs must be the same type (all AC or all DC), and all standby PSUs must be the same type. The higher capacity modules should be configured as standby.

Q: What is the advantage of the DC power supply over the AC version?
A: The DC power supply is designed for environments with existing DC power infrastructure, such as telecom facilities and data centers with -48V DC distribution. It provides the same 3200W output as the AC model but uses direct current input for compatibility with DC power systems.

Q: Does the C9400-PWR-3200DC support hot-swapping?
A: Yes, the C9400-PWR-3200DC is hot-swappable. When redundant power supplies are installed, you can remove and replace a faulty module without interrupting chassis operation or causing network downtime.

Q: What PoE standards does this power supply support?
A: The C9400-PWR-3200DC supports IEEE 802.3af (PoE), 802.3at (PoE+), and 802.3bt (PoE++), as well as Cisco UPOE+ delivering up to 90W per port when used with compatible line cards.
