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.
