Standby Power
When one or both of the PSU
Unit that connects the ztC Endurance system to electrical power. Each system includes two PSUs, located at the rear. power cords are connected to live power outlets, low-level standby power is present in the system. Standby power Low-level power that remains present even after the ztC Endurance system has been powered down. Standby power enables the primary Baseboard Management Controller (BMC) to monitor the status of system components, even when system power is off. Using standby power, administrators or ztC Endurance Customer Support (if authorized) can connect to the system through the 1G management port to diagnose problems, or to turn system power on and off from a remote location.
To completely shut off power, the power cords must be unplugged. enables the primary Baseboard Management Controller (BMC Controller used for out-of-band monitoring and management of the ztC Endurance system. Each ztC Endurance system includes two BMCs; the primary BMC monitors the status of system components, even when system power is off.
BMCs are equipped with an Ethernet port that can be connected to the Stratus ActiveService Network (ASN). BMCs can communicate with the ASN even when the host operating system is unavailable. This allows remote management, and, if necessary, troubleshooting by the CAC or your authorized Stratus service representative over the internet.) to monitor the status of system components, even when the system power is off.
Standby power also allows for continuous operation of the ports used for the BMC: the 1G management ports (see System Ports). Therefore, while the system power is off, administrators (or, if authorized, Stratus Customer Service) can still connect to the system through the 1G management ports to diagnose problems, or to turn system power on and off from a remote location.
