Chapter 2 Hardware Installation
This chapter discusses the basic operational installation and the Disk Drive
installation.
The following topics are covered in this chapter:
Preparing for the Installation
Disk Drive Installation
Table and Shelf Installation
Rack-Mount Installation
2.1 Preparing for the Installation
If you will be connecting your FASTORA DAS-208CC Disk Array to the
computer using a SCSI adapter, installed the adapter(s) in an available slot in
the computer prior to beginning FASTORA DAS-208CC installation. See your
operating system manuals for the configuration procedures for the host bus
adapter.
2.1.1 Disk Drive SCSI IDs
SCSI devices communicate and exchange data by addressing each other‘s
SCSI ID, an unique number assigned to each device. The disk array has four
SCSI channels; two for hosts and the other two for the drives. The disk array
controller is always set to take SCSI ID 7 on each of the drive channels. Eight
drive slots are connected to two separate SCSI drive channels. The slots with
number 1, 2, 3, and 4 are connected to SCSI disk channel 1 and the rest slots
with number 5, 6, 7, and 8 are connected to SCSI disk channel 2. The SCSI

13
FASTORA DAS-208CC Disk Array
IDs for the disk drives will be set automatically according to their placement in
the enclosure, as shown below: Refer to Table 1-2 in 1.4.2 for details.
2.1.2 Terminating Disk Drive Channels
All SCSI buses must be terminated at each end. Termination absorbs electrical
signals and prevents those signals from bouncing back along the bus and
causing interference.
The SCSI drive channels of FASTORA DAS-208CC have been terminated
inside the chassis on the back plane. There is no need to terminate the disk
drives!

SCSI ports.
FASTORA DAS-208CC can be connected to the host computer via 2 Ultra 3
SCSI ports.
2.1.4 Host Bus SCSI ID Assignment
You may assign any SCSI ID to the host channel. The range of SCSI IDs on a
Wide SCSI bus starts from 0 to 15. You can use the LCD panel or a terminal to
set the host channel ID. (Refer to Section 3.1 Configuration Methods for more
information.) Be sure to assign an ID that does not conflict with any other
devices on the host bus as well as the host adapter.
2.1.5 Host Bus Termination
The disk array is shipped with host channel buses terminated. If the disk array
is not the last device on the host bus, you must turn off termination from the
LCD panel or a terminal.
2.1.6 Back Plane
The back plane of FASTORA DAS-208CC is specifically designed to furnish
the stability of voltage and provide the reliability for disk array.
2.1.7 Connecting the Power Cord

Chapter 3 Configuration
FASTORA DAS-208CC can be configured via its LCD panel or via a terminal.
This chapter will discuss the configuration methods and the detailed
information about the operation modes.
This chapter covers the following topics:
Configuring Through the LCD Display Panel
Configuring Through a Terminal
Operation Modes
Main Menu
3.1 Configuring Through the LCD Display Panel
The LCD Panel consists of a two lines 16-character LCD display, two LED
indicators, four push buttons, and a reset button, allowing users to configure
and monitor the operation of the disk array. A menu of configuration options will
appear on the display. By using the Up arrow, Down arrow, ESC, and ENTER
buttons, users can traverse various menu levels and configure his desired
parameters.
The function of the buttons is descried as follows:
(↑) Up Arrow To scroll upward through the menu items;
(↓) Down Arrow To scroll downward through the menu items;
Enter To select a menu item, open a sub-menu, and select a value
ESC To exit a sub-menu and returns to the previous menu.

18
FASTORA DAS-208CC Disk Array
If you wish to start with the LCD display panel as quickly as
possible, refer to Chapter 4.1.1Quick Setup via LCD Display
Panel to configure the disk array.
3.2 Configuring Through a Terminal
The LCD control panel allows the exploration of all configurable features of the
disk array. However, the frame of the LCD panel only allows a few messages
of output. In this case, a very limited amount of information can be displayed at
a given time on the LCD display panel.
In fact, using a terminal to configure your disk array will be exactly the same as
using the LCD display to do the configuration. Unlike the LCD display that can
only show 2 lines of the configuration information, a terminal, connected via a
modem or direct serial interface, displays all information pertinent to a particular
function on a larger terminal screen. In addition, the help information, which is
impractical to be shown on the LCD panel, is also available on the terminal.
3.2.1 Connecting a Terminal
Located at the rear of the disk array, a RS-232 connector, marked as Console,
can be used to support the local terminal access. When connecting a terminal
to the disk array, make sure you have attached the supplied RS-232cable to
the right Console connector. Note that you should set up the communication
parameters before using this terminal. To start up:
1. Plug one end of the supplied RS-232 cable to the port marked as Console
at the rear of the disk array.
2. Connect one end of the RS-232 cable to the COM port of your terminal or
PC.
3. Run an equivalent program of the terminal.
Note

FASTORADAS-208CC, namely:
Baud rate: 115,200
Data bit: 8
Stop bit: 1
Parity: None
Flow Control: None
You shall see a pop-up screen indicating that the connection has been setup
successfully. Then, you may configure the disk array with your terminal. Refer to
section 3.2.3 Control Key Definition under ANSI Terminal to learn the control keys
for terminal emulation.
Please note that if you wish to start to configure with your terminal as quickly
as possible, you may refer to Section 4.1.2 Quick setup via Terminal
Configuration.
3.2.2 Using PC for Terminal Emulation
If you do not have a dedicated terminal, you can still use a PC configured as a
terminal, running a terminal emulation program. Microsoft Windows and
Windows 95 both have built-in terminal emulation support. Please select ANSI
terminal as the terminal type for the terminal emulation. You can also use other
terminal emulation programs such as KERMIT or VTERM. If you cannot see
anything on the screen after the session has been established, press TAB key
followed by Ctrl-D key combination to refresh the screen.
Follow the same steps discussed in section 3.2.1 Connecting a Terminal to
connect your PC to the disk array.

FASTORA DAS-208CC Disk Array
3.2.3 Control Key Definition under ANSI Terminal
Using ANSI terminal display, the following keys are supported:
A- used to scroll upward through the menu items
Z- used to scroll downward through the menu items
ENTER - used to select a menu item, open a sub-menu, and select a value
ESC - used to exit a sub-menu and return to the previous menu
TAB - used to switch between windows
The rest of the alphanumeric keys are also supported for password input and
when prompted for Yes or No input.
3.3 Operation Modes
FASTORA DAS-208CC Disk Array has three operation modes: Self-Diagnostic
Mode, Operation Mode, and Configuration Mode. We will discuss each of the
RAID disk array operation mode in the following sections.
3.3.1 Self Diagnostic Mode
To ensure flawless operation, the disk array has a built-in self-diagnostic utility.
Self-diagnostics will be performed automatically upon power up of the disk
array or right after you restart the unit. In this mode of operation, all
components will be tested. If any problem occurred, it will report to the user.
The Self-Diagnostic mode runs three major diagnostics. The first diagnostic
tests the CPU and supporting the core logic chips, internal bus, memory, SCSI
controllers, and RS-232 controllers. The second diagnostic tests the presence
of disks on each individual disk channel. It also checks the functionality of the
disks found. The last diagnostic tests RAID functionality.
