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 node.
Failure to do so can cause damage to the HP-UX file
structure on the coprocessor hard disk.
ATTENTION
It is also 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.
