Audible Alarms [ES4000/5000/8000 Only]

There are two conditions that cause an alarm to sound on the ES4000, ES5000 and ES8000.

• Disk Drive Failure: If one of the drives in the RAID 1 mirror fails, an alarm begins to sound. The alarm continues to sound until the failed disk is replaced.
• Power Supply Failure: If one of the two power supplies fails completely, an alarm begins to sound. The alarm continues to sound until the failed power supply is replaced. If a power supply fails partially, the alarm does not sound.
