5) Once complete, information of both installed and uploaded firmware versions as well as
compatibility and signature-checking results are displayed.
• If anything is incorrect, click Discard Upload. •
6) To proceed with the update, click Update Firmware.
Warning: Do NOT power off the PRO4X during the update.
7) During the firmware update:
• • A progress bar appears on the web interface, indicating the update status.
• • The front panel display shows the firmware upgrade message.
• The outlet LEDs flash if the relay boards are being updated. If the firmware update does not include •
the update of the relay board firmware, outlet LEDs do NOT flash.
• No users can log in. •
• Other users' operation, if any, is forced to suspend. •
8) When the update is complete, the unit resets, and the Login page re-appears.
Important: If you are using the PRO4X with an SNMP manager, download its MIB
again after the firmware update to ensure your SNMP manager has the correct MIB
for the latest release you are using.

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 PRO4X 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 PRO4X to stop working, you can recover it by using a special
utility rather than returning the device.
Contact Raritan Technical Support for the recovery utility. You will also need an appropriate firmware
file in the recovery procedure.
