PRODUCT NOTICE
Notice of Potential Product Concern
Rockwell Automation issues a Product Notice when it identifies a product(s) anomaly that may cause commercial or customer
satisfaction concerns.
Allen-Bradley 1715-AENTR and AADvance T9110 and T9120
May Not Detect Loss of Power Supply
Reference: 2019-07-002
Date: July 2019
This Product Notice informs you of a potential anomaly that exists with the Allen-Bradley® 1715-AENTR Ethernet/IP
Adaptor Module, the AADvance® T9110 Processor Module, and the AADvance T9120 Processor Eurocard. When
used with redundant power supplies, the affected module may not detect and report the loss of a single supply. If the
redundant supply is subsequently lost, the system will lose all power and shut down without system notification.

– Description –
A potential anomaly exists with the Allen-Bradley® 1715-AENTR Ethernet/IP Adaptor Module, the AADvance® T9110
Processor Module, and the AADvance T9120 Processor Eurocard. When used with redundant power supplies, the
affected module may not detect and report the loss of a single supply. If the redundant supply is subsequently lost,
the control system will lose all power and shut down without system notification.
Internal to the potentially affected modules are blocking diodes that prevent power from one power supply affecting
the detection circuitry for the other power supply. When a single supply becomes non-operational, the detection
circuitry signals the system of the loss resulting in an LED indication on the module’s faceplate and the generation of
a fault alarm. The system will continue to operate on the remaining supply.
On a small percentage of modules, the blocking diodes may allow power from the remaining operational power
supply to affect the detection circuitry for the non-operational power supply. This will prevent detection circuitry for
the non-operational supply from signaling a loss supply condition to the system.
