9.3 Software Upgrading
In this chassis, you can upgrade the software via the IAP tool
(In Application Programming). This offers the possibility, to
replace the entire SW image without having to remove the
flash-RAM from its socket. You can find more information on
this in Chapter 5 ("Service Modes, Error Codes, and
Faultfinding") in the paragraph “IAP Tool”.
