4.3 Start-Up Sequence

4.3.1 Overview

iR5065 / iR 5055 / iR5075 / / /
The system software used to control the machine is stored on the HDD.
When the machine is started, the CPU on the main controller PCB reads the system software from the HDD according to the instructions of the boot ROM boot
program, and writes it to the image memory (SDRAM) of the controller PCB.
While the CPU reads the system software from the HDD to the image memory (DRAM), the control panel shows the following screen, using a progress bar to
indicate the progress of the start-up sequence.
Do not turn off the main power while the progress bar is indicated, as access is being made to the HDD. Turning off the power can cause a fault on the HDD (iden-
tified by E602).
