Power Supply
VessRAID 1800i Series
VessRAID 1800i Series 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 1700i Series
VessRAID 1700i Series 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 319.
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 236 for instructions on replacing a power supply.
Battery
VessRAID uses an optional 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 103 (WebPAM
PROe) or page 153 (CLU).
If the battery does not respond, installing a replacement battery
will correct a marginal or failed condition.
See page 240 for instructions on replacing the battery.
