configuration. High line (200-240 VAC) delivery is required to operate the system in its current
configuration" message and only boot to RBSU.
At POST, the server automatically detects whether the power supplies are connected to high-line power or
low-line power. If the server is configured with eight populated CPU sockets or a detected high power GPU,
the system will halt if it detects that the server is plugged into low-line power. This occurs by design because
systems configured eight processors, and/ or high power graphics cards, with a large amount of memory,
hard drives, or other options might require more power than can be provided by low-line power. POST halts
this low-line configuration as a precaution against the server having insufficient power during operation.
If a you wish to operate a server in this configuration when utilizing low-line power, the power supply solution
should be verified as sufficient using the HP Power Advisor (http://www.hp.com/go/hppoweradvisor). If
the power solution is not deemed sufficient, the server may not have sufficient power to operate normally. If
the solution is deemed sufficient, a ROM-Based Setup Utility option, outlined below, can be used to allow the
system to operate in this configuration.
If the HP Power Advisor has determined that the server can be reliably powered at low-line power in this
configuration, perform the following steps to override the Power Supply Requirements setting in ROM-Based
Setup Utility (RBSU):
1. When the server halts, access RBSU.
2. Select "Advanced Options".
3. Scroll down to "Power Requirements Override" and choose to enable it.
4. Exit RBSU,which will reboot the server and should bypass the message on the subsequent boot.
