NonStop NS2400 Series Planning Guide

DescriptionSystem State
Normal halt condition. Halted processors do not participate in power-fail
handling. A normal power-on also puts the processors into the HALTED state.
HALTED
Loss of optic power from the blade element occurs, or the UPS batteries suppling
the blade elements are completely depleted. When power returns, the system
is essentially in a cold-boot condition.
