System Recovery
 
This section can be referred to in the event the MS2085A/89A does not boot properly and the normal attempts to restart the instrument have failed.
Introduction
If the MS2085A/89A fails to boot properly, a second boot attempt will load a recovery menu as shown in Figure: Recovery Mode. This menu is only displayed when the instrument fails a normal boot process. A failure to boot properly might not indicate a problem. A boot disruption, such as removing power before the instrument can complete the boot process, will initiate a recovery menu on the next boot.
Recovery Mode 
If you see this screen:
1. Select the REBOOT INSTRUMENT button once the recovery menu loads.
2. If boot failure continues, a system recovery can be performed by pressing CONTINUE TO RECOVERY MODE.
The Recovery Mode menu (Figure: Recovery Mode) shows instrument information and provides a variety of recovery options in ascending invasive order:
1. Select REBOOT to reboot the instrument without any further action.
2. Save all internal user files and logs by inserting a USB device and press the EXPORT button.
3. Refer to Reset for information about various reset options.
4. Refer to Boot Order to select a different boot order.
5. Refer to Install SW to SLOT X to reload or update the system software.

Install SW to SLOT X
The recovery mode shows two slots (A and B). These slots contain different system software packages that are installed. Each slot contains the following information:
• Slot name (A,B): Boot version package (A or B).
• Slot count (3,2,1): The count indicates how many unsuccessful boot attempts before the slot is marked as unbootable. Every failed attempt decrements the value until it reaches 0 (unbootable). This count can be reset to 3 using the Reset menu.
• Slot version: The version represents the software package version available in the slot.
You can install a new software package by inserting a USB memory device with the system software file (.raucb) and pressing “Install SW to SLOT X.” The X will be replaced with an A or B depending on which slot is to be overwritten. You will not be able to select which system software file will be installed from the attached USB, it will always install the first one found.
