Yes, that's correct And I doubt that there's an orderly shutdown from the panel... I remember being told of only one procedure, but it would not cause damages/issues of sort. In any case we're speaking about something that was meant to be turned on and never turned off unless some maintenance or a big issue. For scheduled maintenance, the qsecofr / admin account could issue a pwrdwnsys , and for a catastrophe where the terminal is not accessible ... the panel does its job -----Original Message----- From: cctalk <cctalk-boun...@classiccmp.org> On Behalf Of Patrik Schindler via cctalk Sent: Wednesday, January 6, 2021 1:27 PM To: General Discussion: On-Topic and Off-Topic Posts <cctalk@classiccmp.org> Subject: Re: DEDICATED HOBBYIST ALERT: IBM AS/400 9406-F2 for cheap sale in Germany Hello, Am 06.01.2021 um 02:04 schrieb mazzi...@tin.it: > Yeh, I know for a fact you cannot setup Hdds for an as/400 unless with > the ibm factory tool.

What I understood from your last posting is that once you reformat an AS/400 disk for 512 Bytes per sector as used by commodity hardware, you can’t use it again on AS/400, even by reformatting. > About the panel ... let me see... > > Press 1 time "arrow up" to get 02 on the display Press "insert" > > panel will show "02 BN" > Press 4 times "arrow up" so that it changes to "02 BM" > Press 2 times the white power on button, to start the > shutdown/poweroff phase This is *not* an orderly shutdown, but some kind of emergency shutdown procedure to prevent excess damage through RAM content not yet flushed to disk. A bit like doing a „sync“ and immediate power off on Unix/Linux. :wq! PoC
