Exhibit 1.2-1 Installation instructions 1 2 3 Install the iPBridge 2700C in the target device. (See the board layout diagram below.
2 Configuring the iPBridge Set up your iPBridge by first getting an IP address, then use ATTO ExpressNAV to map devices. Default values are appropriate for most other configurations, but may be modified for your needs using ATTO ExpressNAV. Configuration of the ATTO iPBridge, also known as iPBridge Services, is available through the ATTO ExpressNAV, a browser-based interface, or the Command Line Interface (CLI).
2.1 Getting an IP address Set up your iPBridge by first getting an IP address, then use ATTO ExpressNAV to map devices. The iPBridge is set up by default to request an IP address from a DHCP server. If you do not have a DHCP server to assign IP addresses to devices, get an IP address from your network administrator. Use the QuickNAV utility from the CD included with your iPBridge to find your iPBridge on your network. 1 2 3 Work from the computer attached to the iPBridge on the same broadcast domain.
2.2 Target management Devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use the Automatic Target Management feature in the ATTO ExpressNAV interface. or deny access between initiators and devices as needed. CAUTION Changing the device map can affect the host’s view of devices and your application configuration To map devices, you must have a host computer connected to the iPBridge Ethernet port.
Multiple target nodes Multiple targets allow you to create a more configurable mapping scheme which can segregate storage into different iSCSI nodes within the iPBridge, with each iSCSI target having its own set of access criteria. For example, if you have two servers and a library with four tapes and a media changer, the default nodes would provide both servers access to all tapes and the media changer (default target mode).

2.3 Additional configurations Additional configurations to improve usability and security are available on the iPBridge 2700. Use ATTO ExpressNAV or the Command Line Interface. Set the Real Time Clock Before proceeding you should set the Real Time Clock. You can set the time automatically by using the Simple Network Time Protocol (SNTP). SNTP is enabled by default. 1 2 3 Note The iPBridge must remain powered on for more than 24 hours to ensure the date and time are set.
SNMP protocol Remote system monitoring is available using Simple Network Management Protocol (SNMP). An agent resides in the iPBridge which takes information from the iPBridge and translates it into a form compatible with SNMP. If certain conditions arise, the agent sends asynchronous notifications (traps) to a client. Refer to Diagnostic commands on page 43 for detailed information on the commands which regulate SNMP on the iPBridge.
3 ATTO ExpressNAV interface The easiest way to communicate with the ATTO iPBridge is to use the browser-based interface. ATTO ExpressNAV. This chapter provides additional information about the interface and how to use it. The recommended management tool for the iPBridge is ATTO ExpressNAV, a web-based interface which may be accessed from any web browser that supports the latest standards for XHTML 1.0 and CSS1.
Exhibit 3.
3.1 ATTO ExpressNAV pages Each page in the ATTO ExpressNAV interface provides information and/or configuration parameters based on a specific topic. Each page can be reached through the menu at the side of each page An image on each page’s header shows each port in the product faceplate. Each port is clickable and will also take you to the appropriate page.
Manual Target Management: iSCSI Target Management ExpressNAV is the preferred interface for setting up targets and access to targets. This page allows you to set up and configure iSCSI targets individually for Access Control, Device Maps and iSCSI CHAP. For the default target, Access Control and CHAP are disabled by default. For all manually-created targets, Access Control is enabled and CHAP is disabled by default. Refer to Target management on page 11, and Mapping commands on page 53 for details.
4 Updating firmware Several processors control the flow of data in the ATTO iPBridge 2700. The firmware to control these processors can easily be upgraded in the field using the ATTO ExpressNAV interface or the PUT command from an FTP connection. The ATTO ExpressNAV method is preferred. Preliminary steps Using ATTO ExpressNAV 1 1 Connect to ExpressNAV (refer to ATTO ExpressNAV interface on page 19) and click on the Firmware page.

5 Troubleshooting If it is clear that a particular component system is at fault in a problem situation, go directly to that component. If it is not clear, the best approach is to troubleshoot using the inside-out method. You may check on the status of your iPBridge using the ExpressNAV interface. Refer to ATTO ExpressNAV pages on page 21 to see which pages may contain the information you need.
• • • • a bicolor LED, embedded in the connector on each Gigabit Ethernet port, indicates 100/1000 MbE speed. Green on indicates 100MbE and yellow on indicates 1000 MbE. a green LED for each Gigabit Ethernet port indicates link/activity, where on solid indicates link, blinking indicates activity and off is no link is present. a green LED for each Fibre Channel port indicates link where off means no link.
Check host versions Check the following to find problems on attached hosts: • • • • Operating system version Service pack version Host adapter version Host adapter firmware version • • Host adapter device driver version iSCSI driver version If an update is required, perform the update. For an updated list of supported iPBridge host platforms and host adapters, visit www.attotech.com. Check iPBridge product versions and update firmware 1 Enter ATTO ExpressNAV.
able to log in. Enter “iSCSI” into this field for auto iqn discovery. Cat5E and Cat6 cable are the best cabling for the iPBridge. 2 Verify the IP address, subnet mask, and gateway are properly set on each data port on the iPBridge for your network environment. Refer to ATTO ExpressNAV interface on page 19. 3 Verify that the Ethernet speed is set to auto: check the Ethernet page of the ATTO ExpressNAV interface, or check the LED link lights to determine if the Ethernet speed is correct.
7 Some older switches cannot autonegotiate between the host and the switch properly. You could have to force the host or switch to the desired speed. For a NIC using an OS iSCSI driver, continue to the iSCSI OS driver section. 7 Verify that the hosts and the iPBridge are using the same port number to communicate iSCSI on the ATTO ExpressNAV iSCSI page. The default port number for the iPBridge is 3260. 8 Check cable integrity. Check the cables for solid connections.
3 Verify that packets are not being dropped along the LAN/WAN. Many utilities track packet activity and switch statistics. applications, slows the system no matter how fast everything else is in the system. 1 Checking the Ethernet host adapter or NIC Ethernet storage adapters generally outperform accelerated NICs and un-accelerated NICs by offloading most of the processing from the host.
6 Alternative interface options Alternative methods to using the ATTO ExpressNAV interface may be used to manage the iPBridge. ATTO ExpressNAV is the recommended interface. Use the serial port or header 1 Connect a cable from iPBridge RS-232 serial port or header to the serial (COM) port on a personal computer. 2 Turn on the iPBridge. 3 Start a terminal emulation program on the personal computer, and use it to connect to the iPBridge.
