FAQ

Q1. How can a buyer verify the exact 6GK7277-1AA10-0AA0 switch?

Check the complete rating label and confirm CSM 1277, four RJ45 ports, 10/100 Mbit/s operation, 24 V DC supply and 45 x 100 x 75 mm dimensions.

Q2. How can New, Used or Refurbished condition be distinguished?

Request dated photos of the label, all RJ45 ports, power terminal, LEDs, housing and packaging, together with traceable condition records.

Q3. How should supplier legitimacy be checked?

Verify the legal company record, address, payment beneficiary and invoice details, and require the complete article number on the quotation.

Q4. Which specifications should an engineer verify before ordering?

Confirm four RJ45 ports, unmanaged switching, 10/100 Mbit/s rate, 19.2 to 28.8 V DC supply, IP20 rating, mounting method, dimensions and 0.15 kg weight.

Q5. What physical evidence should be requested before payment?

Ask for dated close-up photos showing the label, connector condition, 3-pole power terminal, diagnostic LEDs and packaging.

Q6. Can the successor or another switch suffix replace it automatically?

No. Port count, mounting, power range, dimensions and approvals must be reviewed against the installed S7-1200 network.
