Page 11: Operating As Both A Scsi And Fibre Channel Device
On the SCSI bus, the PSFR-CP41 acts as a SCSI initiator passing requests from hosts on the Fibre Channel network to target devices on the SCSI bus. The PSFR-CP41 uses a single SCSI ID. The default ID is 7 and can be changed when configuring the PSFR-CP41. -
Page 12: Processing Scsi Information
1. A FC host issues a command. The FC host encapsulates the command in the FCP protocol and sends the packet to the PSFR-CP41. 2. The FC port in the PSFR-CP41 receives the packet, interprets the FC infor- mation, and places the packet in buffer memory. -
Page 13: Processing Fibre Channel Information
Processing Fibre Channel Information Processing Fibre Channel Information The PSFR-CP41 processes information from the SCSI bus host by requesting operations of targets on a Fibre Channel Storage Area Network (SAN). The information is processed using the same method as described in the previous section, except it begins with the SCSI host bus issuing commands and the information passing through the PSFR-CP41 to the FC SAN. -

Page 16: Installation Procedure
Installing the PSFR-CP41 Installation Procedure Place the PSFR-CP41 so the rear fan vent and the front intake vents remain clear of obstructions to ensure proper airflow. 1. Remove the router from the protective bag. 2. Determine where the PSFR-CP41 will be mounted. - Page 17 Mounting the PSFR-CP41 in a Rack To reduce injury or equipment damage, the mounting brackets must be level. If the brackets are not level, the PSFR-CP41 cannot be installed correctly. Operating Manual Installing the PSFR-CP41 5. Locate the front of the mounting brackets.

Page 21: Interfaces And Connections
Mounting the PSFR-CP41 in a Rack Interfaces and Connections There are four different types of physical interfaces to the PSFR-CP41: Fibre Channel SCSI RS-232 (Serial port) Ethernet The RS-232 and Ethernet ports are used primarily for PSFR-CP41 configu- ration and management. MIB information for each interface is discussed later in this chapter. -
Page 22: Fibre Channel Connection
Both switches and hubs may allow for individual ports to be configured for different media types. The PSFR-CP41 must be connected to the hub or switch port with the appropriate cabling for the media type in use on both the PSFR- CP41 and the port to which it is connected. -

SCSI bus. If the PSFR-CP41 is located at one end of the SCSI bus, an external terminator should be installed. A terminator is provided with the PSFR-CP41. - Page 24 3. Connect the other end of the SCSI cable to the next SCSI device on the bus. 4. If the PSFR-CP41 is at the end of the SCSI bus, place the terminator provided with the router on the PSFR-CP41’s other SCSI connector. If the router is not at the end of the bus, attach a second SCSI cable to the other SCSI connector.

0. In this mode, the PSFR-CP41 automatically obtains an available address and participates on the loop, as long as there is at least one address available on the loop that is connected to the PSFR-CP41. Fibre Channel supports up to 126 devices on an arbitrated loop. -

Auto addressing is described further in this section. The PSFR-CP41 automatically detects if it is connected to a loop or a switch, and will use the appropriate type without further configuration. -
Page 35: Address Mapping
Indexed Addressing Indexed Addressing allows for generic Fibre Channel host bus adapters to access SCSI devices attached to the PSFR-CP41. This is done by use of a table which is indexed by sequential FCP LUN values, indicating selected BUS:TARGET:LUN devices. - Page 36 An example of such an environment is where hot plug devices may be used, thereby changing the order of devices on the SCSI bus.

SCSI devices attached to the PSFR-CP41. The Access Method used is the SCC Logical Unit Addressing method. In SCC Addressing mode, the PSFR-CP41 will respond to FCP commands, as in a SCC controller device. A subset of the SCC behavior is implemented. LUN mappings corresponding to the SCC Peripheral Device Addressing are inter- preted as controller commands, and are acted on by the PSFR-CP41 directly. - Page 38 Configuring the PSFR-CP41 The PSFR-CP41 uses a menu structure to configure the PSFR-CP41 through the serial and telnet interfaces. The currently selected menu and the firmware version currently executing will be displayed. Menu items are selected by entering the number of the menu desired, and exited by entering an ‘X’. In general, the configuration options present in the serial interface correspond to those available through SNMP and telnet.

Operation Indicators Operation Indicators The PSFR-CP41 router is equipped with rear panel LED indicators for monitoring overall router status. The LED functionality is detailed below: Power This green indicator turns on when power is applied to the router. Fault This amber indicator is lit when the PSFR-CP41 detects a fault condition. -

ID’s greater than 15 (e.g. 16 and up). This problem can be resolved by configuring the PSFR-CP41 to use hard addressing, and setting the AL_PA used by the unit to a value that the HBA will map to an ID with a value less than 16. -
Page 41: Device Management
Device Management Configuring the PSFR-CP41 Device Management The PSFR-CP41 can be managed through the RS-232 port, over Ethernet via Telnet Web-Browser, or via SNMP. FTP and TFTP are also supported for firmware downloads. Serial The serial port allows for configuration of all device characteristics. - Page 42 Configuring the PSFR-CP41 Communicating with the PSFR-CP41 The PSFR-CP41 is designed to function directly out of the shipping container with no special configuration required. However, you have the ability to monitor various aspects of the PSFR-CP41’s performance by connecting a terminal or terminal emulator to the serial port on the rear of the router.

Page 66: Indexed Addressing Option
This is done by use of a table which is indexed by sequential LUN values, indicating selected BUS:TARGET:LUN devices. It is not possible in this mode to address the PSFR-CP41 unit as a controller unit directly when using the Indexed Addressing option. The size of the table is equal to the number of busses times the number of targets per bus, less one initiator ID per bus, times the number of LUNs per target. -
Page 67: Auto Assigned Addressing Option
Auto Assigned Addressing Option Appendix B Auto Assigned Addressing Option The Auto Assigned option is similar to the Indexed addressing, but with the distinction that the table used is created through SCSI device discovery on power up or reset, and not otherwise retained. As the unit performs device discovery on the SCSI bus, the Index table relating FCP LUN values is filled with adjacent FCP LUNs referencing each subsequent SCSI device. -
