WAWEIS 3.3V AC/DC Adapter for Linksys EtherFast EFAH08W EFAH05W EZXS55W

SKU CH-NM66-S39M8

A 3.3 V AC/DC power adapter compatible with Linksys EtherFast EFAH08W, EFAH05W and EZXS55W switches, with 6.5 ft cord and FCC, CE, RoHS certification

  • World-wide 100-240 V input works across regions
  • 3 V DC output matches Linksys EtherFast EFAH08W, EFAH05W, EZXS55W
  • 5 ft cord gives flexible placement
  • FCC, CE and RoHS certified for safety
  • Over-current, over-voltage, short-circuit and total-power protection built in

Replacement 3.3V Adapter

This WAWEIS AC/DC adapter replaces the original mains supply for Linksys EtherFast EFAH08W, EFAH05W and EZXS55W switches. It delivers a regulated 3.3VDC output from a 100-240VAC 50/60Hz input. The unit is not a 7.5VDC adapter and does not use a 3-prong connector. FCC, CE and RoHS certifications confirm compliance with safety standards.

Upgrade From Faulty Units

The adapter replaces a lost, damaged or failing original power supply that shows intermittent operation or no power at all. Over current, over voltage, short circuit and total power protection guard the connected switch against electrical faults. A 6.5 ft power cord provides extra reach compared with shorter factory cables. The jump is worth it when the original unit is unavailable or unreliable.

Desktop Switch Integration

The adapter plugs directly into the DC input of the supported EtherFast models, powering 5-port or 8-port desktop switches without an external brick. World-wide input voltage allows use on any mains supply from 100V to 240V. Built-in overload, overheat and anti-interference features protect the switch electronics. Buyers needing a 7.5VDC supply or a 3-prong connector must select a different model.

Questions about this item

What connector type does the 3.3 V adapter use for the Linksys EtherFast EFAH08W EFAH05W EZXS55W?

The unit is explicitly described as NOT a 3-prong connector and NOT a 7.5 VDC supply; it provides a 3.3 VDC output matched to the listed models.

How do I install the adapter correctly, and what common mistake should I avoid?

Connect the 100-240 VAC mains lead, then plug the 3.3 VDC output into the EtherFast device; the frequent error is using a 7.5 VDC supply instead of the required 3.3 V unit.

When should I replace the power cord or the adapter itself?

Replace the 6.5 ft cord if insulation is damaged or the plug becomes loose; replace the adapter if over-voltage, over-current or short-circuit protection trips repeatedly.
