Updating the HPDU Firmware
When performing a firmware upgrade, the HPDU keeps the power status of each outlet unchanged so that no server operation is interrupted. During and after the firmware upgrade, outlets that were powered before the firmware upgrade remain powered on and outlets that were powered off remain powered off. You must be the administrator or a user with the Firmware Update permission to update the HPDU firmware.
The HPDU web-interface-based firmware upgrade time varies from unit to unit, depending on various external and internal factors. Upgrades through other management systems, such as Sunbird Power IQ, may take additional time beyond the control of the HPDU itself.
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 an upgrade (depending on the number of outlets). The microcontroller is upgraded only when required. 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 HPDU firmware upgrade time.
- Select Maintenance → Update Firmware.
- Click ? and select a firmware file.
-
Click Upload.
When the progress bar indicates that the upload is complete, information of both installed and uploaded firmware versions and compatibility and signature-checking results display.
- If anything is incorrect, click Discard Upload.
-
To proceed with the update, click Update Firmware.
Caution - Warning: Do not power off the HPDU during the update.
During the firmware update process, the following actions occur:
-
Progress bar appears in the web interface, indicating the update status.
-
Front panel display shows the firmware upgrade message.
-
Outlet LEDs blink 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 blink.
-
No users can successfully log in to the HPDU.
-
Other user operations, if any, are forced to suspend.
-
When the update is complete, the HPDU resets, and the Login page appears.
-
Other logged-in users are logged out when the firmware update is complete.
Note - If you are using the HPDU 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.To use a different method to update the firmware, see Firmware Update through SCP or Bulk Configuration or Firmware Upgrade through DHCP/TFTP.
