The Black Box Spare Power Supply is a 12VDC, 1.5A redundant external adapter for KVM devices, suited to users who need a compatible spare or replacement for equipment requiring up to 1.5A.
Recommended For
- IT technicians replacing a failed or missing power supply on a Black Box DCX3000-DVR KVM receiver.
- KVM administrators keeping a spare 12V, 1.5A supply on hand for compatible Black Box equipment to reduce downtime if the installed adapter fails.
- Installers who need a replacement supply with a 3-pin locking connection to help prevent accidental power-cable disconnects on compatible equipment.
Real-World Use Scenarios
- When a compatible KVM device’s original power supply is lost or fails, use the PS656 as a replacement to get the device powered again; confirm the device requires 12VDC and no more than 1.5A.
- For a compatible Black Box DCX3000-DVR Digital KVM Remote User Station, keep the PS656 available as a spare so a failed or missing adapter can be replaced without sourcing a different power supply.
- In a workstation or equipment area where power cables may be tugged, the PS656’s 3-pin locking interface is intended to help prevent accidental disconnection from the compatible KVM device.
- For IT teams maintaining compatible Black Box KVM equipment, storing a PS656 as a spare can make a matching replacement available when a power supply needs to be swapped.
