Downgrade from 3.3.10 to pre-3.3.10:
There is no downgrade sequence limitation. However, firmware
downgrade in a cascading chain is NOT recommended. Consult
Raritan (or Legrand) Technical Support first if downgrade is needed.
Firmware versions earlier than 3.3.10 are compatible with any
pre-3.3.10 version so you can downgrade or upgrade all devices of
the chain in a random order when all firmware versions in the chain
are prior to version 3.3.10.
Note: It is suggested to always stick to the same sequence as the above
diagram though there is no firmware downgrade limitation.
Full Disaster Recovery
For SRC, disaster recovery can be performed via the USB connection
only.
If the firmware upgrade fails, causing the SRC to stop working, you can
recover it by using a special utility rather than returning the device to
Raritan.
Contact Raritan Technical Support for the recovery utility, which works in
Windows XP/Vista/7/10 and Linux. In addition, an appropriate SRC
firmware file is required in the recovery procedure.
Viewing Firmware Update History
The firmware upgrade history is permanently stored on the SRC. It
remains available even though you perform a device reboot or any
firmware update.
To view the firmware update history:
1. Choose Maintenance > Firmware History.
Each firmware update event consists of:

Update date and time

Previous firmware version

Update firmware version

Update result
2. If wanted, you can resort the list by clicking the desired column
header. See
