Installing an IP4700

Abnormal Powerdown

If an IP4700 is powered down abnormally (for example, a plug kick
or a brownout), data is saved to the storage system vault disks (disks
0 through 8), and is not lost. See Figure 2-20. However, when the
IP4700 is powered up again, it will take longer to come on line,
because it first must write the vault disk data to the correct volumes.
