Namely, that the "DTDs will be attached to the automation device by an Ethernet switch or hub and that this subnet is isolated from the Internet for security." << 2.2 Automation Device Components This document assumes that DTDs will be attached to the automation device by an Ethernet switch or hub and that this subnet is isolated from the Internet for security. The automation device contains the following components: ? Management application accessible via front panel and/or Internet. ? Automation application client (see ADC-3) ? Remote SMC device server (see ADC-3) ? Ethernet ADI port (see ADC-3 and T10/07-469r2) While the automation application client and remote SMC device server must use the Ethernet iADT port to access DTDs? iADT ports, the network protocol servers and the management application do not necessarily use the same Ethernet port. >> While it is true that some installations will be configured this way, it is also true that some installations will require that the DTDs' ethernet port is accessible by the external network. We cannot limit what vendors are going to do here. Thanks, Kevin D. Butt SCSI & Fibre Channel Architect, Tape Firmware MS 6TYA, 9000 S.
