Recovering Stacking Units after Upgrade Failure
If a Stacking Unit encounters the update failure, with its failsafe capability
, you can restore the
Stacking Unit’s function by yourself.
1. Make sure only one Stacking Unit (the one that encounters the update failure) is connected to
the Main Unit. If not, refer to STEP 2 in the previous section Updating Stacking Units for
Failsafe Upgrade Feature for instructions.
2. Check the Front Panel LCD display on the Stacking Unit to see whether it enters the boot
loader mode as one of the picture shown below:

If not, press and hold FUNC and ESC on the Front Panel of the Stacking Unit simultaneously,
and power cycle the Stacking Unit at the same time. This forces it to enter the boot loader
mode.
3. Follow the steps outlined in General Update Procedure in this chapter to upgrade your
Stacking Unit., but you must choose the .hex file, “R-P2SBLR-0C5.hex,” as the firmware file.
User Stations
Updating User Stations for Failsafe Upgrade Feature (P2-UST Only)
The failsafe capability is a standard feature of the P2-EUST. P2-UST with a version older than
1F9 does not have this feature. For an older P2-UST, you can simply upgrade its firmware to get
the failsafe feature.
The procedures are the same as those outlined in General Update Procedure. Note that the
filename for upgrading the User Station for failsafe capability is “V5_1F9.hex” or later.
Verify the Firmware Version
On the upgraded User Station, activate the OSUI screen, and press F8 to display the User
Station’s version information.
