1

1 O&M Precautions



When performing high-voltage and AC operations, use dedicated tools and wear

protective equipment.



Before replacing a component which is not hot swappable, you must switch off the

upstream circuit breaker or fuse, and verify that the component to be replaced is powered

off.



Assess impact on the system before switching off the general input circuit breaker or

turning off the cooling system during parts replacement.



Do not install or remove power cables for a device which is powered on. Transient

contact between the core of the power cable and the conductor may generate electric arcs

or sparks, which may cause fire or hurt human eyes.



Before removing component cables, mark the cables with their corresponding port

numbers for later connection.



Before powering off the system, seek the customer's consent first.
