Damage Can Result—Circuit board damage can result if
you do not practice proper ESD procedures or attempt to
remove/insert a circuit board with node power applied.
CAUTION
Mandatory Steps—It is mandatory that appropriate software
shutdown procedures are followed for the A
X
M coprocessor
prior to removing power from the A
X
M node.
Failure to do so can cause damage to the HP-UX file
structure on the coprocessor hard disk.
ATTENTION
It is highly recommended that you perform a node processor
software shutdown when preparing to power off the A
X
M
node. This provides for an orderly departure from the LCN
network.
