Power Supplies
Astra ES are equipped with redundant power supplies. The
advantage of dual power supplies is that, should one fail, the
other will continue powering the subsystem until the faulty one
can be replaced. Astra ES is capable of operating on a single
power supply. As a result, if one power supply fails you must
watch the front panel LEDs or Astra Web GUI in order to
become aware of the condition.

The power supplies are hot-swappable, meaning you can leave
the Astra ES running when you replace the bad one. Be careful,
however, to remove the faulty power supply and not the good
one, or Astra ES will come to an immediate stop and your data
will be unavailable until the system is powered and booted
again.

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.

Battery
Astra ES uses a battery as backup power for the cache. Should
a power failure occur, the battery enables the cache to hold data
up to 60 hours. The battery recharges during normal Astra ES
operation.

In most cases, installing a replacement battery will correct a
marginal or failed condition. The battery is located in the cooling
unit above the controller. Remove the cooling unit for access.
