Power On Self Test (POST)
A group of tests run when the FCR200 is powered on.
Processor
Contains the arithmetic and logic, control, and internal memory units that control the FCR200.
- R -
Reset SCSI
For a specific SCSI bus, the host clears all inputs and outputs and then resets the bus and all the devices connected to it.
Responder
The logical function in an N_Port responsible for supporting the exchange initiated by the originator in another N_Port. A FC responder is comparable to a SCSI target. The FCR200 is often the responder.
Router
A device which selectively forwards data between storage networks based on administratively defined preferences. The forwarding decision is based on paths between address mappings among dispersed initiators and targets.
- S -
SCC Addressing
Amenu name.
SCSI
Small Computer System Interface. An industry standard for connecting peripheral devices and their controllers to an initiator.
SCSI Adapter
A
SCSI Addressing
A fast/wide SCSI adapter supports up to 16 devices, including itself. Each device has its own unique SCSI address. The SCSI address of a device dictates the device’s priority when arbitrating for the SCSI bus. SCSI address “7” has the highest priority. The next highest priority address is “6” followed by 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, with “8” being the lowest priority address.
The fast/wide SCSI adapter is factory set to address 7. A narrow SCSI adapter supports up to eight devices, including itself. SCSI address “7” has the highest priority followed by 6, 5, 4, 3, 2, 1, and 0.
SCSI Bus
The means of transferring SCSI data between SCSI devices. It is an
SCSI Device
A single unit on the SCSI bus, identifiable by a unique SCSI address. A SCSI device can act as an initiator or target. For
SCSI Port
An opening at the back of the FCR200 providing connection between the SCSI adapter and the SCSI bus.
SCSI Status
A menu name used to show the number of SCSI devices on the bus.
Shortwave
Lasers or LEDs that emit light with wavelengths around 780 nm or 850 nm. When using multimode fibre (50 nm), shortwave lasers can be used with FC links less than 500m. To achieve longer lengths,
