Installing the SAN Switch 2/8 Connecting a Cable to an SFP Module Use these steps to connect the SFPs and cables to SAN Switch 2/8 ports as required. Note: The ports and cables used in trunking groups must meet specific requirements. For a list of these requirements, refer to the hp StorageWorks ISL Trunking V3.0.x/V4.0.x User Guide. 1. Remove the shipping plugs from the appropriate ports. 2. Position the SFP so that the key (the tab near the cable-end of the SFP) is on top. 3.
Installing the SAN Switch 2/8 4. Connect the cables to the SFPs as appropriate to the fabric topology, by positioning each cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the SFP. See Figure 17. SHR-2499B Figure 17: Inserting a cable into an SFP Note: The cable is keyed so that it can only be inserted correctly into the SFP. If the cable does not slide in easily, check the orientation.
Installing the SAN Switch 2/8 Note: HP strongly recommends backing up the configuration. This ensures that a complete configuration is available if required for a replacement switch. For instructions on how to back up the configuration, refer to “Backing Up System Configuration Settings” on page 68 in Chapter 4. Installing Multiple Switches into an Existing SAN Use these steps to set up more than one SAN Switch 2/8 in an existing SAN. 1.
Installing the SAN Switch 2/8 Cascading Switches The domain id number uniquely identifies a switch in a fabric. Normally, the switch automatically assigns the domain ID when a switch is first powered on or when the switch disable/enable command is executed. When two switches are cascaded together, there might be an initial domain ID conflict if the switches had been assigned the same domain ID prior to being cascaded. This can be avoided by changing the domain ID with the configure command.

Technical Specifications Environmental Requirements Table 7 lists the environmental ranges that are acceptable when the SAN Switch EL is operating, and the acceptable ranges when the switch is not operating.
Technical Specifications Serial Port Specifications The Serial port can be used to connect to a computer workstation to configure the switch IP address without connecting to the fabric. The Serial port’s parameters are 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. The port requires a straight serial cable with a female 9-pin subminiature-D connector. Only pins 2, 3, and 5 are supported; if pin 7 is used, the signal must always be driven high, using the pinouts listed in Table 9.
glossary Glossary This glossary defines terms used in this guide or related to this product and is not a comprehensive glossary of computer terms. Glossary AL_PA Arbitrated Loop Physical Address; a unique 8-bit value assigned during loop initialization to a port in an arbitrated loop. Alias Address Identifier An address identifier recognized by a port in addition to its standard identifier. An alias address identifier may be shared by multiple ports.
Glossary AW_TOV Arbitration Wait Time-out Value; the minimum time an arbitrating L_Port waits for a response before beginning loop initialization. Bandwidth The total transmission capacity of a cable, link, or system. Usually measured in bps (bits per second). May also refer to the range of transmission frequencies available to a network. See also Throughput. BB_Credit Buffer-to-buffer credit; the number of frames that can be transmitted to a directly connected recipient or within an arbitrated loop.
Glossary Command Line Interface that depends entirely on the use of commands, such as through telnet or SNMP, and does not involve a GUI. Community (SNMP) A relationship between a group of SNMP managers and an SNMP agent, in which authentication, access control, and proxy characteristics are defined. See also SNMP. Connection Initiator A port that has originated a Class 1 dedicated connection and received a response from the recipient.
Glossary E_Port Expansion Port; a type of switch port that can be connected to an E_Port on another switch to create an ISL. See also ISL. EE_Credit End-to-end Credit; the number of receive buffers allocated by a recipient port to an originating port. Used by Class 1 and 2 services to manage the exchange of frames across the fabric between source and destination. See also End-to-end Flow Control, BB_Credit. EIA Rack A storage rack that meets the standards set by the Electronics Industry Association.
Glossary FCIA Fibre Channel Industry Association. An international organization of Fibre Channel industry professionals. Among other things, provides oversight of ANSI and industry developed standards. FCP Fibre Channel Protocol; mapping of protocols onto the Fibre Channel standard protocols. For example, SCSI FCP maps SCSI-3 onto Fibre Channel. Fibre Channel Transport A protocol service that supports communication between Fibre Channel service providers.
Glossary Fx_Port A fabric port that can operate as either an F_Port or FL_Port. G_Port Generic Port; a port that can operate as either an E_Port or F_Port. A port is defined as a G_Port when it is not yet connected or has not yet assumed a specific function in the fabric. Gateway A device such as a switch that connects different subnets together. A switch can be used as a gateway from the Ethernet to the Fibre Channel.
Glossary L_Port Loop Port; a node port (NL_Port) or fabric port (FL_Port) that has arbitrated loop capabilities. An L_Port can be in one of two modes: ■ Fabric mode Connected to a port that is not loop capable, and using fabric protocol. ■ Loop mode In an arbitrated loop and using loop protocol. An L_Port in loop mode can also be in participating mode or non-participating mode. Latency The period of time required to transmit a frame, from the time it is sent until it arrives.
Glossary Name Server Frequently used to indicate Simple Name Server. NL_Port Node Loop Port; a node port that has arbitrated loop capabilities. Used to connect an equipment port to the fabric in a loop configuration through an FL_Port. Node Name The unique identifier for a node, communicated during login and port discovery. Node A Fibre Channel device that contains an N_Port or NL_Port.
Glossary Port_Name The unique identifier assigned to a Fibre Channel port. Communicated during login and port discovery. POST Power On Self-Test; a series of tests run by a switch after it is turned on. Private Device A device that supports arbitrated loop protocol and can interpret 8-bit addresses, but cannot log into the fabric. Private Loop An arbitrated loop that does not include a participating FL_Port.
Glossary Route As applies to a fabric, the communication path between two switches. May also apply to the specific path taken by an individual frame, from source to destination. Routing The assignment of frames to specific switch ports, according to frame destination. RR_TOV Resource Recovery Time-out Value; the minimum time a target device in a loop waits after a LIP before logging out a SCSI initiator.
Glossary Switch Hardware that routes frames according to Fibre Channel protocol and is controlled by software. Target A storage device on a Fibre Channel network. Tenancy The time from when a port wins arbitration in a loop until the same port returns to the monitoring state. Also referred to as loop tenancy. Throughput The rate of data flow achieved within a cable, link, or system. Usually measured in bps (bits per second).
Glossary U_Port Universal Port; a switch port that can operate as a G_Port, E_Port, F_Port, or FL_Port. A port is defined as a U_Port when it is not connected or has not yet assumed a specific function in the fabric. UDP User Datagram Protocol; a protocol that runs on top of IP and provides port multiplexing for upper-level protocols. ULP_TOV Upper-level Time-out Value; the minimum time that a SCSI ULP process waits for SCSI status before initiating ULP recovery.
