Problem: The controller’s STATUS LED is on but there is no RS-232 display. (The
controller’s STATUS LED is on the controller board and is only visible if you
open your enclosure or if it is connected to a status LED on your enclosure.)
Check that the RS-232 cable is the correct type (direct connect). Check that the
terminal emulation utility on the computer system is properly configured. See
Accessing the Disk Array Administrator Using the RS-232 Serial Port on page 3-1.
Problem: The controller reports a SDRAM memory error.
Check that the SDRAM DIMM is fully seated in the connector and the latches are
fully engaged into the DIMM notches. Check that the SDRAM is from the Chaparral
approved vendor list. See the Chaparral technical support web site for the latest
updated information.
Problem: The controller reports a Battery error.
Verify that the 3-cell NiMH battery pack is being used. The battery packs from other
Chaparral external RAID controllers, such as the G6322, are not compatible. You will
not damage the battery pack or the controller by using the wrong battery, but the
controller will not operate properly. Check the battery pack cable for breaks. Ensure
that the battery connector is fully seated in the controller connector mate.
Warning And Error Events
There are a number of conditions that trigger warning or error events, activate the
alarm, and may affect the state of the STATUS and FAULT LEDs. The alarm or
buzzer sounds mainly when the Disk Array Administrator displays a warning or error
event. The controller’s STATUS LED is on the controller board and is only visible if
you open your enclosure or if it is connected to a status LED on your enclosure. The
FAULT LED is only visible if it is connected to a fault LED on your enclosure.
The alarm will silence when you acknowledged the event by pressing Esc. The events
in these categories are listed below.
