CHAPTER 5: Configuration and Operation

5.12 Network Control of SCSI Switch

The 6 x 4 Electronic SCSI Matrix Switch may be controlled over a TCP/IP network through its LAN port.

5.12.1LAN-PORT CONFIGURATION

You can remotely control the SCSI Switch through a standard 10-Mbps Ethernet connection running TCP/IP. In the SCSI Switch’s factory-default setting, the LAN port will be enabled and the RS-232 COM2 port (which shares the same circuitry and is most often used for daisychaining SCSI Switches) will be disabled. If you want to daisychain SCSI Switches, you will need to disable the LAN port and enable the COM2 port. To do this, scroll through the control menus in the switch’s front- panel LCD (see Section 4.3) until you reach the SET SERIAL PORTS menu. Move the cursor to the DAISY CHAIN option and press ENTER on the switch’s keypad to change the setting from N to Y.
