Interpreting Operations Panel LEDs
The operations panel monitors array hardware components. The panel is not
redundant, but an array can continue to operate if it fails. See your array support
provider for information about servicing the operations panel.
Figure 1-4 shows the operations panel LEDs, which can alert you to errors and
conditions that require your attention. Table 1-2 describes the LEDs. Report any
serious problems to your array support provider.
Note: The serial number for your array is on a label on the operations panel.
