I did not have recent experience with 5494.
But way back a couple of years ago microcode updates were distributed as PTFs to
OS/400.
It would be downloaded to 5494 at first contact (and also updated on diskette).
You would only need to reboot controller to activate the changes at first
convenience.
(And 5494 stores current configuration in CMOS, so Perle is not original.)

Subject:  Upgrading Controller Microcode





I have a bunch of remote workstation controllers that I needed to upgrade
the microcode for 'Y2K' compliance.  Upgrading the Perle 494's was a snap
(as are most things with Perle).  I was able to download the update from
their web site.  It comes with an install utility to create the image on a
STANDARD floppy diskette.  All you need to do is insert the disk and reboot
the controller.  The configuration is stored in CMOS and backed up on to the
floppy disk with each boot.  Does anyone know if the IBM 5494 controllers
work the same way?  IBM also puts the files up on their web site, but in
typical IBM fashion, you need a 2.88 MB floppy drive in order to create the
microcode diskette.  Who the heck has such an animal?  Nobody that I know
of.... So you end up having to order the microcode from them.... I have no
doubt it cost more to package and ship the diskettes to me than what they
are worth... No wonder everything blue is so expensive...
