Removal and replacement procedures 24
These symbols, on power supplies or systems, indicate that the equipment is supplied
by multiple sources of power.
WARNING:
To reduce the risk of injury from electric shock, remove all power cords
to completely disconnect power from the system.
•
Each enclosure has two or more power supply cords. A single rack or cabinet
may contain more than one enclosure. Power may be supplied in a redundant
fashion. Removing any single source of power does not necessarily remove power
from any portion of the system. When performing any service other than hot-plug
module replacement, you must completely disconnect all power to that portion of
the system.
•
When performing service procedures on enclosures, shut off the circuit breakers to
both A and B AC power feeds and then disconnect all power cords from the
outlets before servicing.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
WARNING:
To reduce the risk of electric shock or damage to the equipment:
•
Never reach inside the chassis while the system is powered up.
•
Perform service on system components only as instructed in the user documentation.
WARNING:
A risk of electric shock from high leakage current exists. Before connecting the AC
supply to the power enclosures, be sure that the electrical outlets are properly grounded
(earthed).
CAUTION:
Always be sure that equipment is properly grounded and that you follow proper
grounding procedures before beginning any installation procedure. Improper grounding can
result in ESD damage to electronic components. For more information, see "Preventing
electrostatic discharge (on page
22
)."
CAUTION:
When performing non-hot-plug operations, you must power down the server blade
and/or the system. Use caution when performing other operations, such as hot-plug
installations or troubleshooting.
CAUTION:
Protect the equipment from AC power fluctuations and temporary interruptions with
a regulating facility UPS device. This device protects the hardware from damage caused by
power surges and voltage spikes and keeps the system in operation during a power failure.
Power down
Be sure that the partner server blades are the first units to be powered down and the last to be powered
back up. Taking this precaution ensures that the system and the OS are shut down in an orderly manner.
IMPORTANT:
If installing a hot-plug device, it is not necessary to power down the MDS600.
To power down the MDS600:
