1.5 Connecting SCSI devices to the SCSI port The ATTO iPBridge SCSI port connects SCSI storage devices to the network. The SCSI port is a bus capable of supporting up to15 devices in LVD mode and each bus is capable of 40, 80 or 160 MB/sec. (Ultra, Ultra2 or Ultra3) transfer rates. The SCSI bus auto-negotiates the appropriate sync rates with the connected devices.
Cabling Cables and devices must be chosen to maximize performance and minimize the electrical noise from the high-speed data transfers available with the SCSI protocol. Cabling and termination methods become important considerations for proper performance. SCSI cables and devices are subject to specific length and number limitations to deal with electrical problems that arise at increased operating speeds.
1.6 Configuring the iPBridge Communicate with the ATTO iPBridge through the GbE port using ATTO ExpressNAV or Telnet or through the serial port. The preferred method to communicate with and manage the iPBridge is through the GbE port using ATTO ExpressNAV, a GUI web-based interface. ATTO QuickNAV, a utility program, automatically finds your iPBridge on the network so that you can begin configuration. You may use the Command Line Interface through the serial port or through the GbE port using Telnet.
Using ATTO ExpressNAV ATTO ExpressNAV is the recommended management tool for the iPBridge. It is a webbased graphical user interface (GUI) that allows you to manage the iPBridge by clicking choices and commands in traditional GUI fashion or by entering Command Line Interface commands directly, as you would in a terminal emulation session. The minimum requirement for browsers is Internet Explorer 5.5 or Netscape Navigator 6.2. Access from any web browser that supports the latest standards for XHTML 1.
The iPBridge will save the changes and perform a restart. set ipgateway dp0 e.f.g.h where e.f.g.h is a valid gateway. 9 To save the settings, type saveconfiguration restart 10 Once rebooted, verify that the iPBridge can be accessed by your network using standard network techniques such as the ping command. Using Telnet Up to three Telnet sessions can be conducted simultaneously.
