1. QUICK 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 Microsoft iSCSI initiator. 1.1 Make sure all devices on the SCSI side of the system are powered down, i.e. iS5xx iSCSI Bridge, SCSI target devices, and SCSI hosts. 1.
1.8 Type in https://192.168.1.200:4443/enter.php as the URL (see Glossary) and press enter. The following Login page should appear: 1.9 Enter the default Username and Password and click on the Login tab. 1.9.1 Username: admin 1.9.
1.10 You should now be at the Home page. Click on the “iSCSI Target” tab. 1.11 Now you can start configuring your unit for your final iSCSI topology (See section 1.16 Figure B). Modify 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 iSCSI Host machine wishing to access the SCSI devices connected to the iS5xx iSCSI Bridge.
1.12 Confirm changes. 1.13 Once you’ve confirmed changes, the iSCSI Target page will renew with your updated settings.
1.14 In order for your settings to take affect, 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 after 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 successfully configured your iS5xx iSCSI Bridge. If the SCSI bus settings (see section 5.5) or the Web Port interface access (see section 5.
1.17 Connect the SCSI devices to the iS5xx iSCSI Bridge. 1.17.1 Connect the cable from the SCSI devices to the 68-pin SCSI port on the iS5xx iSCSI Bridge. 1.17.2 Make sure the IDs of 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 default. 1.18 Connect the iS5xx iSCSI Bridge’s Ethernet port to your iSCSI Host computer via a CAT 5e or CAT 6 cable.
1.22 Power on your iSCSI Host computer. Open the Microsoft Initiator. Click on the “Initiator Settings” tab. Modify your “initiator node name” accordingly.
1.23 Click on the “Target Portals” tab. Add an available portal.
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”.
1.25 Your Target Portal is now configured.
1.26 Click on the “Available Targets” tab. Click on Refresh. After the screen has refreshed, all available targets through the iS5xx iSCSI Bridge will be displayed. You will need to “Log On” to each one before your iSCSI Host computer is able to fully communicate with the SCSI targets. If 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.
2. DESCRIPTION 2.1 General. Congratulations on your purchase of Paralan’s iS5xx series iSCSI Bridge! Paralan’s family of iSCSI Bridges make it possible to merge parallel SCSI storage into IP (iSCSI) Storage Area Networks (SANs).
3.1.16 256MB SDRAM. 3.1.17 833MHz Freescale processor. 3.1.18 Capable of assigning a unique iSCSI name to each device on the SCSI side of the bus. 3.1.19 Can automatically obtain an IP address from a DHCP server or the user can manually assign an IP address, Subnet mask and Gateway to the iSCSI Protocol Port and Web Port. 3.1.20 Diagnostic web page monitors unit’s boot status. 3.1.21 Diagnostic LEDs for quick and easy unit status. 3.1.
4.3 SCSI Topology. Paralan’s family of iSCSI Bridges may be connected anywhere on the SCSI bus. All models are supplied with on-board terminators enabled. In most cases the iSCSI Bridge will be placed at the end of the SCSI bus and terminators should NOT be disabled (see Figure C).
4.4 SCSI Cables. The most important ingredient in the successful installation of any SCSI system is proper cabling. Many round SCSI cables are, at best, marginal on single-ended systems and will not work at all on differential SCSI systems. Many other round SCSI cables are assembled in a manner that has no regard for wire pair selection. These cables appear to work most of the time but may cause intermittent problems on the SCSI bus that are extremely difficult to troubleshoot.
4.5 Connecting SCSI Devices. SCSI cable installation is easy. This installation assumes the topology in Figure C of section 4.3. 4.5.1 Simply connect a SCSI cable into Paralan’s iSCSI Bridge’s 68-pin High Density “P” SCSI bus Connector (see Image 1 of section 4.2). 4.5.2 Connect the other end of your cable to your SCSI device(s). 4.5.3 Make sure to abide by the SCSI cable length limitations recommended in Table 1 of section 4.4. 4.5.
4.7 Ethernet Cables. You must choose your Ethernet cable carefully depending upon your configuration. If you are connecting your iSCSI Bridge directly to a management computer, a crossover cable is necessary. If you are connecting through an Ethernet switch or router, a straight-through cable will suffice. The type of cable used is equally important (see Table 2 below).
4.10 LEDs. There are 5 LEDs on the iSCSI Bridge that can be used for status/diagnostics (see Image 2 of section 4.6) 4.10.1 SCSI Activity (Yellow). The SCSI Activity LED is labeled “SCSI” on the iS520 and iS550. During normal operation, this LED turns on when there is SCSI activity on the SCSI bus. However, the LED will also indicate when there are no SCSI targets on the SCSI bus. After initial boot, i.e.
4.10.5 Ethernet Link (Yellow/Green). The Ethernet Link LED is labeled “LINK” on the iS520 and iS550. This LED illuminates solid green if the iSCSI Bridge is connected to another active Ethernet component and has negotiated a data transmission rate of 10 or 100Mb/sec. The LED will turn solid yellow for a negotiated rate of 1000Mb/sec. 4.11 Accessing Paralan’s Web-based Utility. For your convenience, use Paralan’s iSCSI Bridge’s Web-based Utility for configuration.
4.11.5 The Login page below should appear. Enter your Username and Password and click on the Login tab. The default Username is “admin” and the default Password is “password”. 4.11.6 You should now be at the Home page. You are now ready to configure your iSCSI Bridge (see section 5).
5. CONFIGURING THROUGH WEB-BASED UTILITY 5.1 General. Paralan’s iSCSI Bridge Web-based Utility configures the unit for many different environments and applications; monitors boot status and updates firmware. Please note that your unit’s serial number is depicted at the upper right hand corner of each web page of the utility. 5.1.2 UNIT MUST BE FULLY BOOTED BEFORE CHANGES TO THE WEB-BASED UTILITY CAN BE MADE! The unit is considered fully booted when the “Status” LED is solid green. 5.1.
5.3 Diagnostic Page. The Diagnostics Page’s three purposes: 5.3.1 To ensure a clean boot of the iSCSI Bridge. If any part of the iSCSI Bridge unit fails to initialize, it will be indicated on this page. In such an event, refer to the Troubleshooting Appendix E of this book. 5.3.2 The current firmware your unit is running is also displayed on this page. 5.3.3 Finally, you can reset your unit by clicking on the “Reboot Device” button. Once pressed, it will take 10 seconds before the unit reboots.
5.4 Web Port Page. By using the Web Port page, the user can modify the “IP Address”, “Subnet Mask”, “Gateway” and “Web Port” settings for the Web-based Utility. By default, there are two network ports on the iSCSI Bridge connected to the same physical RJ45 connector; the Web Port and the iSCSI Target Port. To simplify access to the Bridge you can set the Web Port settings to mirror the iSCSI Target Port settings.
5.5 SCSI Bus Page. This page is used to configure certain parameters specific to the SCSI bus interface. Namely: 5.5.1 SCSI ID: You must choose a unique value for this ID. No other device on the SCSI bus can have a duplicate ID. 5.5.2 Termination: The iSCSI Bridge has on-board terminators. You can toggle these terminators on/off via this page. 5.5.2.1 If you turn the terminators off and the Bridge is at the end of the SCSI bus, i.e. your system has the topology of section 4.
5.6 iSCSI Target Page. By using the iSCSI Target page, the user can modify the “IP Address”, “Subnet Mask”, “Gateway”, “iSCSI Name Prefix”, “iSCSI Protocol Port”, “Max Connections” and “Authentication Method” settings for the iSCSI Target on the Bridge. By default, the iSCSI Bridge’s connection type is set to Static, i.e. the IP Address and Subnet Mask are permanent, as shown in the screen capture below.
5.6.1.1 One-Way CHAP. One-Way CHAP sets a “Username” and “Secret” in the Target (iS5xx iSCSI Bridge) that an initiating device must use in order for the Target to authenticate the Initiator for communications. You must choose “CHAP” on the “Authentication Method” pull-down menu before you can enable “One-Way” CHAP in the “CHAP Direction” pull-down menu. Once you have done so, you can specify a “Target Username” and a “Target Usersecret”.
5.6.1.2 Mutual CHAP. Mutual CHAP sets a Secret for both the Target (iS5xx iSCSI Bridge) and Initiator. You must choose “CHAP” on the “Authentication Method” pull-down menu before you can enable “Mutual” CHAP in the “CHAP Direction” pull-down menu. Once you have done so, you can specify both a Target and Initiator “Username” and “Usersecret”. Ensure that your iSCSI Intiator is correctly configured for authentication. Please see the Glossary for further information.
5.7 Updating Firmware. The iS5xx allows you to update its firmware via the Webbased Utility. Follow the steps below: 5.7.1 Click on the Admin page tab and click the “Proceed” button. 5.7.2 You will need to choose the file you wish to upload using the Browse button and then click the Upgrade button. Once you click the Upgrade button, the Status LED will turn solid red during burning. All files must be “img” files and are case sensitive. Currently the only files that can be uploaded are: 0.img, 1.img, 2.
5.7.3 Wait until the “Upgrade Complete” message appears and the Status LED returns to a solid green state before continuing to the next file you wish to update. If you wish to update an additional file, repeat steps 5.7.1 through 5.7.3. 5.7.

Typically used to connect computers directly together, i.e. computers that are NOT connected via a hub, switch or router. Firewall – The primary method for keeping a computer secure from intruders.
Target are protected from unauthorized iSCSI access. Mutual CHAP provides an added protection over One-Way CHAP for iSCSI communications on the Storage Network. See CHAP and One-Way CHAP. One-Way CHAP – Username and Secret in the Target (iS5xx iSCSI Bridge) that an initiating device must use in order for the Target to authenticate the initiator for communications. When the Initiator tries to contact the Target, the Target will challenge the initiator to provide the correct Secret.
URL – Uniform Resource Locator. The address that defines the route to a file on an Internet server. URLs are typed into a Web browser to access Web pages and files.
C. Troubleshooting a. Reset Button. A manual reset switch is located on the LED end of the iSCSI Bridge. On the iS520 (pictured below) and the iS550 (Rack Mountable version) this switch is accessible through a pinhole on the panel. By pressing this button momentarily, the user can fully reboot the unit while maintaining previous user configuration data. By pressing and holding the button for 15 seconds, the unit will reboot and reset to factory default configuration settings.
incommunicable. If you have changed the IP Address of the Bridge, make sure that your Management/iSCSI Host computer is on the same subnet as the modified IP Address. If you do not remember what settings you’ve modified on your Bridge, you can always return to factory default settings by pressing and holding the reset button down for 15 seconds. D. Factory Defaults. The iS5xx iSCSI Bridge is initially sent out with factory default settings for your Web-based utility.
