Connecting the array to servers and switches
See
“Cabling the P6300/P6500 EVA” (page 58)
for examples of connecting servers and switches
to the array in server-based management and array-based management configurations.
Labeling cables using labeling kit
A labeling kit is provided with the disk enclosure. Label both ends of each cable using the materials
in the supplied labeling kit.
Connecting the power cords
WARNING!
To reduce the risk of electric shock or damage to the equipment:
•
Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
•
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
•
To remove power to the equipment, unplug the power cord from the power supply.
•
Route the power cord so that it is not likely to be walked on or pinched by items placed against
it. Pay particular attention to the plug, electrical outlet, and the point where the cord is attached
to the array.
To protect your system from power failure related downtime, each array ships with a redundant
power supply. See
Table 3 (page 30)
to determine the best method for connecting your power
supplies to your power source to eliminate downtime due to power-related failure.
When connecting the power cables, use the power cables shipped with the array. After power is
supplied to the array, the power supply automatically senses the input voltage and the power
supply LED illuminates as solid amber.
NOTE:
If you ordered the AF092A rack, HP recommends that you use the 1.37 meter (minimum
length) power cords.

Level of Protection
Connection Method
Protects you from downtime when one of the array power supplies fails.
The remaining power supply/fan module can operate the array until you install
a replacement module.
Array power supplies connected to
one power source
Protects you from downtime when one of the array power supplies fails.
Protects you from data loss when one of your power sources fails, due to a pulled
cable or tripped breaker.
The remaining power source can power the EVA until the failed power source is
restored or relocated.
Depending on the cause and duration of the power outage, you can use this time
to properly shut down your storage subsystem.
Array power supplies connected to
two separate power sources
Protects you from downtime when one of the array power supplies fails.
Protects you from data loss when one or both of your power sources fails, due to
a pulled cable, tripped breaker, or local power outage.
The remaining power source or the UPS will power the array until power is restored
to the source. Depending on the cause and duration of the power outage, you
can use this time to properly shut down your storage subsystem.
Array power supplies connected to:
•
Two uninterruptible power
supplies
•
Two separate power sources
For more information about power sources, see the HP P6300/P6500 Enterprise Virtual Array
User Guide.
