Configuring SCSI devices

1If you have not already, open an ExpressNAV session. For instructions, refer to Opening an ExpressNAV session on page 21.

2Determine the current speed and transfer rates: type at the SCSI page.

3SCSI Port Bus Speed controls the transfer rate at which the iPBridge attempts to negotiate with its SCSI devices. Default is Ultra3. Complete the appropriate settings.

4SCSI Port Sync Transfer specifies whether synchronous SCSI transfers should be negotiated with devices on the specified SCSI port. The default is enabled. Change the setting if desired.

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 42 for detailed information on the commands which regulate SNMP on the iPBridge.

Contact your network administrator for the MIB software and appropriate MIB file for your iPBridge. Use the SNMP page of the ExpressNAV interface to enable traps or extended traps.
