Note:
SCSI Termination
All SCSI buses require termination on both ends of the bus to
prevent signal degradation. Most SCSI card supplies the termi-
nation on the origination end of the SCSI bus. Termination for
the opposite end if the bus is provide by the vendor.
the SCSI adapter internal connector and the its SCSI-IN
connector.
b. Add the SCSI LVD cable supplied with the SCSI adapter kit
to RAID subsystem SCSI OUT connector. The end of the
SCSI bus farthest from its SCSI OUT must have a
terminator installed.
Note:
LCD status Termination
There are a variety of failure conditions that cause the RAID
subsystem monitoring LED to light. Table1-1 provides a sum-
mary of the front panel LED and RAID subsystem LED.

• Step 9 RAID Creation Method
It is necessary to connect LCD panel with keypad or a serial device
(terminal emulation) in order to create the RAID system. The
RAID subsystem is normally delivered without LCD pre-installed.
Method 1:
LCD Panel with Keypad
The LCD status panel informs you of the Disk Array’s current
operating status at a glance. If you need to add the front panel
and keypad function, you also need one another drive bay space.
Install the LCD Module on the controller backplane in order to
operate the LCD interface function. For additional information on
using the LCD panel and keypad to configure the RAID subsystem
see “LCD Configuration” on Chapter 6.
