Downgrade from 3.3.10 to pre-3.3.10:
There is no downgrade sequence limitation.
Firmware versions earlier than 3.3.10 are compatible with each other
so you can downgrade or upgrade all devices of the chain in a
random order when .
Note: Firmware downgrade in a cascading chain is NOT recommended.
Consult Raritan Technical Support first if downgrade is needed. It is
suggested to always stick to the same sequence as the above diagram.
A Note about Firmware Upgrade Time
The PDU firmware upgrade time varies from unit to unit, depending on
various external and internal factors.
External factors include, but are not limited to: network throughput,
firmware file size, and speed at which the firmware is retrieved from the
storage location. Internal factors include: the necessity of upgrading the
firmware on the microcontroller and the number of microcontrollers
that require upgrade (which depends on the number of outlets). The
microcontroller is upgraded only when required. Therefore, the length of
firmware upgrade time ranges from approximately 3 minutes (without
any microcontroller updated) to almost 7 minutes (with all
microcontrollers for 48 outlets updated). Take the above factors into
account when estimating the PDU's firmware upgrade time.
The time indicated in this note is for PX3TS web-interface-based
upgrades. Upgrades through other management systems, such as
Sunbird's Power IQ, may take additional time beyond the control of the
PDU itself. This note does not address the upgrades using other
management systems.
Full Disaster Recovery
If the firmware upgrade fails, causing the PX3TS device 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 PX3TS
firmware file is required in the recovery procedure.
