The 8271-216 is a manageable ethernet switch from 1996 with full duplex 10base-t ports. https://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/2/897/ENUS196-112/index.html&request_locale=en

Mine has two additional 100base-tx modules (universal feature cards).
One module seems to be dead.

The switch is functional except for one essential point, it doesn't
write it's diagnose info and it's configuration to disk. After reboot
all settings are lost.

To make sure the 1MB flash disk is working I made an upgrade to software revision 5.1 (bootimage and mainimage). Unfortunately this does not
solve the problem.

Does anyone experienced the same problem or can give me a tip on how to
get the switch to re-enable its memory?

Regards

Wolfgang
