 The user management operation, if any, is forced to suspend.
7. When the update is complete, a message appears, indicating the
update is successful.
8. The Dominion PX device resets, and the Login page re-appears. You
can now log in and resume your operation.
Note 1: The other logged-in users are also logged out when the firmware
update is complete.
Note 2: If you are using Dominion PX with an SNMP manager, you
should re-download the Dominion PX MIB after the firmware update.
This ensures your SNMP manager has the correct MIB for the latest
release you are using. See
Using SNMP (on page 136).
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 web-interface-based upgrades.
Upgrades through other management systems, such as Raritan'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.
Viewing Firmware Update History
The firmware upgrade history, if available, is permanently stored on the
Dominion PX device.
This history indicates when a firmware upgrade event occurred, the prior
and new versions associated with the firmware upgrade event, and the
upgrade result.
To view the firmware update history:
1. Choose Maintenance > View Firmware Update History. The Firmware
Update History dialog appears, with the following information
displayed.
