APC Switched Rack PDU AP7900B
It lets you power-cycle individual outlets over the network to reboot hung equipment remotely.
Not for: Home labs that only need more outlets in a rack.
What the AI looks for in Power Distribution Units
- Input plug and circuit
- Match the PDU plug to the receptacle: NEMA 5-15P for 15A, 5-20P or L5-20P for 20A, L5-30P for 30A circuits. A mismatched plug either will not fit or will not deliver the rated capacity.
- Continuous load
- Keep sustained load at or below 80% of the circuit and PDU amp rating. This is the standard derating for continuous loads and it prevents nuisance trips.
- Outlet types
- Choose NEMA 5-15R outlets for consumer gear, or IEC C13 and C19 outlets for servers and switches. IEC outlets lock in better and are what server power cords use.
- Feature tier
- Basic PDUs only distribute power. Metered PDUs show load. Switched PDUs add remote on/off per outlet. Pay for metering or switching only if you will monitor or reboot equipment remotely.
- Mounting
- Choose 1U horizontal for short racks or 0U vertical for full-height racks. Vertical PDUs save rack units and place outlets near each server.
Brands that matter
- APC (Schneider Electric): The reference brand for metered and switched rack PDUs.
- CyberPower: Good-value basic and metered rack PDUs.
- Tripp Lite (Eaton): Wide range of basic to switched PDUs.
What to avoid
- Daisy-chaining PDUs or power strips
- Running a 20A plug PDU on a 15A circuit through an adapter
Questions
Is a PDU the same as a surge protector power strip?
No. Many PDUs have no surge suppression. Check the spec sheet if you need surge protection, or put the PDU behind a UPS.
