Hard disk drive status LED (amber)
Each hard disk drive has a status LED. When this amber LED is lit
continuously, it indicates a drive failure. When it is flashing, it indicates that
a drive Identify or Rebuild is in progress.
Rear view: power supply
The two hot-swap power supplies are on the rear of the EXP3000.
Attention: The EXP3000 comes with two installed power supplies. When one
power supply fails, the power-supply unit must be replaced to reestablish
redundancy. When you replace a failed unit with a new power supply, make sure
that you perform this operation in less than 10 minutes to prevent overheating.
The power-supply controls and connectors are shown in the following illustration.
