About the DuraStor Storage Subsystem Additionally, four 68-pin very-high-density SCSI connectors connect the disk channels of the DuraStor 312R storage enclosure. They are: s DISK CH 3 s DISK CH 0 s DISK CH 2 s DISK CH 1 See Appendix A, Port Information connector pin-out details. Two RS-232 serial ports each connect a controller to a VT-100 terminal, and are used when you want to access Disk Array Administrator. Serial A port is for Controller 1; Serial B port is for Controller 2. The switch in the lower right corner of the panel sets the keyboard/keypad input control to either INT (internal, via the OCP) or EXT (external, via the VT-100 keyboard or a computer running Hyper Terminal). Setting the switch to EXT disables the OCP buttons. Note: The front bezel LEDs will work whether the OCP is being used or not. Setting this switch to EXT will not disable the front bezel LEDs. Optical SFP Transceiver The Fibre Channel-to-SCSI RAID appliance uses a hot-swappable Small Form Factor Pluggable (SFP) transceiver. The SFP optical transceiver provides operations up to 2.5 Gb/sec. The transceiver includes a lost signal detect circuit which provides TTL logic high output when an unusable input signal is detected. Figure 2-11. Optical Transceiver 2-11
