1.6 About SCSI
Be aware of the following issues before using SCSI devices.
1. SCSI ID: Each device attached to the SCSI host adapter must be assigned a unique SCSI ID,
which distinctively identifies a SCSI device for its data transfer and processing. While
connecting more than one SCSI device, each device should have different ID numbers.
2. Terminator: SCSI is featured with high scalability. In order to ensure reliable data
transmission on the SCSI bus, an electrical pathway that consists of adapters and devices,
there should be installed a terminator at the end of the bus. No matter how many SCSI
devices (up to 15) are attached to the bus, a terminator must be added to the last device.

Chapter 2 – Installation
This chapter contains 6 parts:
•The Signal LEDs
•Set the SCSI ID
•Set the Mode
•Install the hard disk drives
•Connect the SCSI port
•Replace the hard disk drives
Notice: Make sure to power off the system during installation or changing any configuration.
2.1 The Signal LEDs
The signal LEDs of the MS-3020 is as figure 2-1 shows. Besides the power LED, there are 8 LEDs on
the front panel of the MS-3020. Every 2 LEDs indicate the status of a hard disk drive.

2.2 Set the SCSI ID
On the rear panel of the MS-3020 there is a SCSI ID switch as figure 2-2 shows. Set the SCSI ID by
adjusting the switch up or down. (Don’t set ID 7. It is normally reserved for the SCSI host adapter)
Setting SCSI ID and configuration mode: Be sure that each device has a unique ID number (see 1.6).
No matter how many MS-3020s (up to 15) are installed and connected, the SCSI ID set on every
switch cannot be the same. The selectable number for the MS-3020 is from 0 to 15.

Table 2-2
1. Pin 1: Reserved
The default is OFF.
2. Pin 2: JBOD Mode vs. Normal Mode
The default is JBOD. It combines 2 or more hard disk drives into a big one. The enlarged
capacity is convenient for mass data storage. In Normal mode the SCSI adapter will detect
the hard disk drives you have connected. You need to enable the SCSI adapter’s LUN support.
Take Adaptec AHA-39160 as example. In SCSI Bios under point SCSI options you need to set
the Multiple LUN to the on state so that the computer can detect all hard disk drives.
3. Pin 3: SCSI Host Transfer Rate at 80MB/s vs. 40MB/s
The default is 80MB/s. If the SCSI adapter is not capable or the signals become unstable after
connecting some MS-3020, lower the speed to 40MB/s.
4. Pin 4: SCSI Host Transfer Rate at 160MB/s
The default is off, but if pin 4 is adjusted to ON, the highest transfer rate will reach 160MB/s.

5. Install the other hard disk drives by repeating step 1 to 4.
Then, set the hard disk drives as Master or Slave in accordance with figure 2-8. Connect in this way,
otherwise the signal LEDs cannot display correctly.

2.5 Connect the SCSI Port
Connect one MS-3020
Connect any one of the SCSI ports on the back of the MS-3020 to the external SCSI port on the host
PC with the enclosed SCSI LVD cable. Then, plug a terminator into another SCSI port on the back of
the MS-3020. If there is no SCSI port on the host PC, insert a SCSI adapter like the Adaptec AHA-
39160 or AHA-39320.
Daisy chain of MS-3020
Use SCSI LVD cables to connect two or more MS-3020, and add a terminator to the last MS-3020. See
figure 2-9 and refer to 2.2 for installing more MS-3020.

Notice
1. It is recommended not to attach any single-ended device to the SCSI adapter where the MS-
3020 is connected. It will drop the performance of the MS-3020.
2. It is invalid to adjust DIP switch during operation. Before changing the setting, power off the
host PC and the MS-3020 first. You had better set JBOD or Normal mode right in the
beginning. The later change may damage the stored data.

Chapter 3 – Troubleshooting
If the installed MS-3020 does not function normally, please check the following items.
1. LEDs do not display normally after powering on
Examine if DIP switch was set right, and if signal line was connected badly.
2. Red LED lights after installing a HDD
If you have installed a hard disk drive, but the red LED lights, please do the following three
things:
•Re-plug the IDE cables and the status signal lines, which are 3-pin color cables
connecting to CN6.
•Replace the hard drive if the red LED still lights.
•Contact the distributor if the problem still exists.
