⚙️ Fit Notes

• Confirm the switch model and original adapter number before ordering. Not every 2530, 1820 or 1920S switch uses this external adapter.
• The connector must match in physical shape, keying and electrical pinout. A visually similar 4-pin connector does not guarantee compatibility.
• This adapter outputs 54V DC. Do not connect it to equipment requiring 12V, 19V, 24V or another voltage.
• The adapter does not increase the connected switch’s rated PoE budget.
• The 2930F 8G PoE+ models require a higher-output 180W adapter such as 5066-5559 and are not compatible with this 90W unit.
• The 84W adapter 5066-5568 is intended for different equipment and should not be treated as interchangeable.
• Connect the DC plug to the switch before connecting the AC power cable.
• The included North American cable uses a NEMA 5-15P wall plug. Other regions require an appropriately approved IEC C13 cable.
• The linked C13 cable is an optional spare or replacement because a compatible power cable is already included with this listing.
