Description
Indicator
Switch Used to enable the automatic power on
restart feature, which specifies how the disk
array is powered on when the AC power is
turned on or restored after a power outage.
ENABLE: When the AC power is turned on, the
disk array is powered on automatically.As with
all sophisticated electronic equipment, unstable
power conditions during a restart can cause
problems. This switch should be in the ENABLE
position only if the power to the disk array is
subject to power conditioning equipment, such
as a UPS, to ensure that the power restored to
the disk array is stable. If your site does not
have a UPS, keep this switch in the DISABLE
position. After a power outage, follow the
manual restart procedure only after power has
been restored and verified to be stable.
DISABLE: The disk array must be powered
on manually, using the PS ON/OFF switch
(10) or the host power control interface (PCI)
(mainframe only).Do not change the switch
position unless directed to do so by HP service
personnel.
Switch Determines how the disk array is powered
on or off. During normal operation,
this switch may be in either position,
depending on your operating environment.
REMOTE: Disk array is powered on/off by the
instructions of the host PCI (mainframe only).
LOCAL: Disk array is powered on/off by the PS
ON/OFF switch (10).Do not change the switch
position unless directed to do so by HP service
personnel.
Switch Used by an HP support representative to test
the functioning of the LEDs on the control panel
or to reset various alarms. During normal
operations, this switch should be in the middle
position between LED TEST and CHK RST. Do
not change the switch position unless directed
to do so by HP service personnel.
