The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

CSCO - CSCO-CNTRL-BRD(=)
The version of the Controller board listed above was recently introduced containing a software change.
The Software change caused an issue where upon loss of AC power to a single rectifier in a redundant system, no system alarms are generated, and the AC/DC panel status LEDs fail to indicate the condition. The controller and rectifier do recognize the condition.
This only affects alarming. It does not affect the power system.
A customer reported that their alarms were not working properly when one of the AC power feeds was removed from a redundant power system.
This issue was introduced during a recent cost reduction activity, when a new revision of software was implemented.
The system fails to generate an AC Failure Alarm when a single AC power feed is removed from the shelf assembly. The AC/DC panel status LEDs will also fail to indicate the condition.
There is no workaround for this issue.
Cisco recommends a fix-on-fail strategy for this problem.
Service Logistics has known-good inventory at this time.
The standard RMA process and delivery times are in effect.
