Power Supply
VessRAID 1840s
VessRAID 1840s has two power supplies. The advantage of two
power supplies is that, should one fail, the other will continue
powering the subsystem. The power supplies are hot-swappable.
VessRAID 1740s
VessRAID 1740s has only one power supply and it is not
replaceable onsite. If you need to replace the power supply,
contact Technical Support and make arrangements to return the
subsystem to Promise for service. See page 291.
Fan Failure
As noted above, if a power supply fan fails, you must replace the
power supply. Without the fan to cool it, the power supply will
overheat and eventually fail anyway.
See page 208 for instructions on replacing a power supply.
Battery
VessRAID uses a battery as backup power for the cache. Should
a power failure occur, the battery enables the cache to hold data
up to 72 hours. The battery recharges during normal VessRAID
operation.
First, try reconditioning the battery. See page 90 or page 135.
If the battery does not respond, installing a replacement battery
will correct a marginal or failed condition.
See page 212 for instructions on replacing the battery.
