1. QUI K INSTALLATION GUIDE
These instructions will get the user up and running quickly using the most basic settings
and topology. This setup assumes that both your management and iSCSI host computer
are running Windows 2000/XP. It also assumes that your iSCSI Host computer will be
running the Microso t iSCSI initiator.
1.1 Make sure all devices on the SCSI side o the system are powered down, i.e.
iS5xx iSCSI Bridge, SCSI target devices, and SCSI hosts.
1.2 Connect your management computer to the iS5xx iSCSI Bridge’s Gigabit
Ethernet port labeled “iSCSI” (See Figure A).
1.2.1 I your management computer is using a 10/100 Network card you will
need to use a “crossover” cable that is CAT 5, CAT 5e, or CAT 6
compliant.
1.2.2 I your management computer is using a GbE (Gigabit Ethernet) Network
card you can use either a straight-through or crossover cable that is CAT
5e or CAT 6 compliant.
1.3 Apply power to the iS5xx iSCSI Bridge. Wait until the “Status” LED (Light
Emitting Diode) on the bridge turns solid green. A solid green on the Status
LED indicates that the unit has ully booted and is ready or Ethernet
communication. I the Status LED does NOT turn green, please re er to
Appendix C section d.
1.4 I you have not already done so, boot your management computer. I you are
using a irewall, ensure that port 4443 is open between your management
computer and the iS5xx iSCSI Bridge.
1.5 Once your management computer is ully booted, make sure that the “Link” LED
on the iS5xx iSCSI Bridge is illuminated. I it is not illuminated, you may be
using an incorrect Ethernet cable. Make sure your con iguration agrees with the
cabling requirements o step 1.2.
1.6 Set the management computer’s IP address to 192.168.1.xxx (xxx can be
substituted with any available address except 200) and subnet to 255.255.255.0.
Reboot the management computer, i needed, or settings to take e ect.

1.7 Now that your management computer has rebooted, open your Web browser.
Windows IE (Internet Explorer) 5.5 or higher is recommended.

1.8 Type in https://192.168.1.200:4443/enter.php as the URL (see Glossary) and
press enter. The ollowing Login page should appear:
1.9 Enter the de ault Username and Password and click on the Login tab.
1.9.1 Username: admin
1.9.2 Password: password

Page 10
1.10 You should now be at the Home page. Click on the “iSCSI Target” tab.
1.11 Now you can start con iguring your unit or your inal iSCSI topology (See
section 1.16 Figure B). Modi y the iSCSI Target Port settings accordingly.
Ensure that the iSCSI Host computer and the iS5xx iSCSI Bridge are on the
same subnet.
This subnet must match the iS SI Host
machine wishing to access the S SI devices
connected to the iS5xx iS SI Bridge.
The correct Gateway number must be
entered if using a Gateway to reach the iS5xx.
Otherwise, leave blank.

Page 11
1.12 Con irm changes.
1.13 Once you’ve con irmed changes, the iSCSI Target page will renew with your
updated settings.

Page 12
1.14 In order or your settings to take a ect, you will need to reboot the unit. Click
on the Diagnostics tab. On the Diagnostics page, click on “Reboot Device”.
The unit will begin reboot a ter 5 seconds. Wait until the “Status” LED on the
Bridge turns solid green.
1.15 Once the iS5xx iSCSI Bridge has rebooted and the “Status” LED is solid green
you have success ully con igured your iS5xx iSCSI Bridge. I the SCSI bus
settings (see section 5.5) or the Web Port inter ace access (see section 5.4) is to
be changed, you will need to re-login. See steps 1.8 and 1.9 or instructions on
how to log in.
1.16 It is now time to connect all devices or your inal setup. Make sure
all devices on the SCSI side o the system are powered down, i.e. iS5xx iSCSI
Bridge, SCSI drives, and SCSI hosts.

1.17 Connect the SCSI devices to the iS5xx iSCSI Bridge.
1.17.1 Connect the cable rom the SCSI devices to the 68-pin SCSI port on the
iS5xx iSCSI Bridge.
1.17.2 Make sure the IDs o the SCSI devices connected to the iS5xx iSCSI
Bridge are set to a values other than 7.
1.17.3 Terminate the SCSI bus at the last physical SCSI device. The iS5xx iSCSI
Bridge is terminated internally by de ault.
1.18 Connect the iS5xx iSCSI Bridge’s Ethernet port to your iSCSI Host computer
via a CAT 5e or CAT 6 cable. I your management computer is unctioning as
your iSCSI Host computer, this step can be skipped.
1.19 Turn on your SCSI targets and wait or them to be ready.
1.20 Apply power to the iS5xx iSCSI Bridge.
1.21 Wait until the Status LED on the bridge turns solid green. The iS5xx iSCSI
Bridge will automatically discover all SCSI targets on the bus. I there are no
SCSI targets connected, the “SCSI” LED will constantly pulse. In this case,
see the Troubleshooting section C.b in the Appendices.

1.22 Power on your iSCSI Host computer. Open the Microso t Initiator. Click on the
“Initiator Settings” tab. Modi y your “initiator node name” accordingly.

1.23 Click on the “Target Portals” tab. Add an available portal.

Page 16
1.24 Enter an Address that matches the “IP Address” you entered in step 1.11. Enter
the Socket port that matches the “iSCSI Protocol Port” you entered in step 1.11
Click “OK”.

Page 17
1.25 Your Target Portal is now con igured.

Page 18
1.26 Click on the “Available Targets” tab. Click on Re resh. A ter the screen has
re reshed, all available targets through the iS5xx iSCSI Bridge will be
displayed. You will need to “Log On” to each one be ore your iSCSI Host
computer is able to ully communicate with the SCSI targets. I a target
drive is to be permanently located, use the “Persistent Targets” tab to set its
location so that it will be automatically available upon system boot-up.
Each “Name”
represents an
actual S SI drive
connected to a
single iS5xx
iS SI Bridge.

2. DES RIPTION
2.1 General. Congratulations on your purchase o Paralan’s iS5xx series iSCSI
Bridge! Paralan’s amily o iSCSI Bridges make it possible to merge parallel
SCSI storage into IP (iSCSI) Storage Area Networks (SANs). I you do not
have an IP SAN, Paralan’s iSCSI Bridges will easily and inexpensively locate
storage and backup SCSI devices anywhere or disaster recovery or remote
backup – yards, meters, kilometers, or miles – the distance is unlimited! Paralan
o ers the iSCSI Bridge in three standard orm actors to meet a variety o
con iguration needs:
2.1.1 iS520: Stand-Alone Box version. Simply connect cables and
apply power.
2.1.2 iS521: Board version. Per ect or OEMs and System Integrators
to incorporate into their own packages.
2.1.3 iS550: Rack Mountable version. Conveniently mounts Paralan’s
iSCSI Bridges into storage racks.
