All my life, whenever I'm doing any hardware upgrades I have always pulled
the plug from the socket. Now granted, this is for PCs; I don't have much
of a track record on iSeries hardware.
I'm going to install some additional memory, and my natural inclination
would be to disconnect the power. However, I've had folks from IBM tell me
to never remove the power except for the most dire situations, such as
replacing planar boards.
Those of you who have done this, what do you do? Do you disconnect power?
