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.

No tools are required for the procedure.

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. The battery is hot-swappable.

No tools are required for the procedure.
