2.5 Power Supply alerts
Power-conditioning uninterruptible power supplies are a highly cost-effective step in defending servers from
electrical dangers to their sophisticated and delicate electronic circuits. Once power going to servers has
been conditioned properly, the next critical server subsystems to protect are their power supplies. Dell EMC
PowerEdge servers are designed to offer redundant power supplies.
As shown in the figure below, iDRAC monitors power supply fan functionality and for voltage variances from
preset upper and lower thresholds. If either fan performance or voltage readings are out of tolerance, iDRAC
generates an entry in the log and send the alert. As with CPUs, this type of alert is often visible on properly
configured hypervisor consoles and can trigger an automatic live migration of VMs, if necessary.
