Black Box PS651 Spare Power Supply
Overview
The Black Box PS651 is a direct replacement power supply designed to maintain continuous operation for the KV0416A and KV1424A KVM switches. When a primary power source fails or requires replacement, this unit ensures your critical switching infrastructure remains online, preventing downtime in environments that depend on uninterrupted access to servers or workstations.
Compatibility
This power supply is specifically engineered for the Black Box KV0416A 16-port KVM switch and the KV1424A 24-port KVM switch. It is not compatible with other Black Box KVM models or third-party equipment. Ensure your KVM switch model number matches exactly to guarantee proper fit and function.
Installation Notes
Connect the PS651 to the designated power input port on the KV0416A or KV1424A KVM switch. Use only the provided power cord and ensure it is connected to a grounded AC outlet. Avoid using extension cords where possible to minimize signal interference and power loss. The unit operates within standard indoor environmental conditions; do not expose to moisture or extreme temperatures.
