Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
NOTE: If the reset button is flashing and an LED is lit continuously, either the
devices on that LED’s bus don’t match the controller’s configuration, or an error has
occurred in one of the devices on that bus. Also, a single LED that is lit indicates a
failure of the drive on that port.
Flashing OCP Pattern Display Reporting
Certain events can cause an alternating display of the OCP LEDs. These patterns are
described in Table 4–4.
