Introducing the PSFR-CP41 PSFR-CP41 Benefits Availability With two units, dual loop attachment provides redundancy and no single point of failure. Connectivity SCSI devices may be attached to Fibre Channel storage networks to share data and increase address space. Distance SCSI cable length from hosts to devices is increased from 25m to 10,000m, facilitating remote or disaster tolerant sites. Performance 100 Mbytes/sec Fibre Channel (200 Mbytes/sec bi-directional) offers increased bandwidth when

How the PSFR-CP41 Works Introducing the PSFR-CP41 How the PSFR-CP41 Works The PSFR-CP41 acts as a pass-though device that translates Fibre Channel FCP to and from a SCSI bus so devices on these two types of media can communicate with each other. It attaches to either a Fibre Channel or SCSI host, and transfers the command, data, and status information to SCSI or Fibre Channel targets. The host passes packets to SCSI or Fibre Channel targets as if the PSFR-CP41 were just another device along the

Introducing the PSFR-CP41Operating as Both a SCSI and Fibre Channel De Operating as Both a SCSI and Fibre Channel Device The router is both a SCSI and Fibre Channel device operating on a SCSI bus and Fibre Channel network simultaneously. The SCSI Side 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 PSF

Processing SCSI Information Introducing the PSFR-CP41 Processing SCSI Information The following describes how the router processes 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. 3. The PSFR-CP41’s processor interprets the information and programs the SCSI controller to proces

Introducing the PSFR-CP41 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.

Installing the PSFR-CP41 Mounting the PSFR-CP41 in a Rack Installation Procedure Place the PSFR-CP41 so the rear fan vent and the front intake vents i 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. 3. Remove any blanking panels and other equipment from the chosen rack location. 4. Install the cage nuts on the vertical mounting rails in the rear of the rack cabinet. U42093-J-Z716-1-74 Operating

Mounting the PSFR-CP41 in a Rack Installing the PSFR-CP41 5. Locate the front of the mounting brackets. 6. Attach the brackets to the front mounting rails, using two screws on each side. Be sure to use only the top and bottom holes in each bracket. (The middle holes will be used to attach the front cover panel after the unit is installed.) Tighten the screws securely. To reduce injury or equipment damage, the mounting brackets must be ! level. If the brackets are not level, the PSFR-CP41 cannot
