Documentation from the manufacturer
Faults and fixes 6GK5786-2AB60-2AA0
Problems with 6GK5786-2AB60-2AA0: the red F LED is on
The F (fault) LED of a SCALANCE switch also comes on when one of the two redundant power inputs L1/L2 is not connected; that is the most common message and not a defect. Also: a port configured as monitored without link, a ring fault or a rejected C-PLUG. The cause is shown in the web interface under Fault.
What do I check when replacing a 6GK5786-2AB60-2AA0?
Carry over the C-PLUG with the configuration, then the replacement starts with the same settings. Without C-PLUG set the IP address, VLANs and ring settings again via the web interface or PST. Check that the firmware version matches the ring or redundancy partners.
Fault not fixed: replace, exchange or repair the 6GK5786-2AB60-2AA0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6GK5786-2AB60-2AA0 refurbished (tested, with a test report per serial number) or new in factory packaging, with a 24-month warranty. The current lead time is shown with the condition on this page. Prefer an exchange: you get a refurbished unit straight away and return the faulty one within 14 days. Repairing your own unit is also possible: diagnosis, then a fixed price.
What information should I send for a quick diagnosis?
A photo of the rating plate (order number, product version, firmware), the exact fault code or LED state, when the fault occurs (at power-up, on enable, under load) and what you have already tried. For PLCs an export of the diagnostic buffer, for drives the parameter set. With that we can usually say the same day whether replacing, exchanging or repairing is best.
