1 General InformationI The hp StorageWorks edge switch 2/16 provides dynamic switched connections between Fibre Channel servers and devices in a storage area network (SAN) environment. SANs introduce the concept of server-to-device networking and multi-switch fabrics, eliminate requirements for dedicated connections, and enable the enterprise to become data centric. A SAN provides speed, high capacity, and flexibility for the enterprise, and is primarily based upon Fibre Channel architecture.
General InformationI Multiple switches and the HAFM server communicate on a local area network (LAN) through one or more 10/100Base-T Ethernet hubs. One or more 12-port Ethernet hubs are optional and can be ordered with the switch. Up to three hubs are daisy-chained as required to provide additional Ethernet connections as more switches (or other Hewlett Packard managed products) are installed on a customer network. Figure 1–1 illustrates the switch, HAFM server, and Ethernet hub.
General InformationI Switch Management Out-of-band (non-Fibre Channel) management access to HP products is provided through an Ethernet LAN connection to a switch front panel. The following out-of-band management access methods are provided: • Management through the HAFM application. The HAFM application includes the edge switch 2/16 Product Manager application. This GUI resides on the HAFM server and provides a single point of management for all directors and switches.

General InformationI Figure 1–3 on page 1-5 illustrates inband product management. In the figure, the managed product is an edge switch 2/16.
General InformationI • Diagnostic software that performs power-on self-tests (POSTs) and port diagnostics (internal loopback, external loopback, and Fibre Channel (FC) wrap tests). The FC wrap test applies only when the switch is configured to operate in S/390 mode. • Automatic notification of significant system events (to support personnel or administrators) through e-mail messages or the call-home feature.
General InformationI • Simple network management protocol (SNMP) management using the Fibre Alliance MIB that runs on the HAFM server. Up to 12 authorized management workstations can be configured through the HAFM application to receive unsolicited SNMP trap messages. The trap messages indicate operational state changes and failure conditions.
General InformationI Multi-Switch Fabrics A Fibre Channel topology that consists of one or more interconnected switches or switch elements is called a fabric. Operational software provides the ability to interconnect switches (through expansion port (E_Port) connections) to form a multi-switch fabric. The data transmission path through the fabric is typically determined by fabric elements and is user-transparent.
General InformationI the creation of a single fabric. A segmented link transmits only Class F traffic; the link does not transmit Class 2 or Class 3 traffic. The following conditions cause ports to segment: — Incompatible operating parameters - either the resource allocation time-out value (R_A_TOV) or error-detect time-out value (E_D_TOV) is inconsistent between switches. To prevent port segmentation, the same E_D_TOV and R_A_TOV must be specified for each switch.
General InformationI Weight: 26 pounds (11.8 kilograms) Power Requirements: Input voltage: 100 to 230 VAC Input Frequency: 47 to 63 Hz Plan for single phase or phase-to-phase connections and 5-ampere dedicated service Airflow Clearance in Rack: Sides: None Top and Bottom: None Front and Rear: 3.0 inches (7.

General InformationI Figure 1–4: HAFM Server The server is mounted in a slide-out drawer in an HP-supplied equipment rack. The HAFM server or Internet access to the embedded web server interface is required to install, configure, and manage the switch. Although a configured switch operates normally without HAFM server intervention, an attached server should operate at all times to monitor switch operation, log events and configuration changes, and report failures.
General InformationI • Eighteen gigabyte (GB) or greater internal hard drive. • 160 megabyte (MB) or greater RAM. • Removable DVD/CD-ROM drive. • Removable 100 MB disk (Zip®) drive. • 56K internal modem. • One internal 10/100 Mbps Ethernet adapter with RJ-45 connector (provides public LAN interface to switches and remote clients). Ethernet Hub The HAFM Server and managed switches connect through a rack- mounted 10/100 Base-T Ethernet hub. Figure 1–5 illustrates the optional 12-port hub.
General InformationI • System event information displays at the attached HAFM server, a remote workstation communicating with the HAFM server, or the embedded web server interface. • LEDs on the switch front panel or FRUs illuminate to indicate a hardware malfunction. • An unsolicited SNMP trap message is received at a management workstation, indicating an operational state change or failure.
General InformationI Each remote workstation must have access to the LAN segment on which the HAFM server is installed. Switch administrative functions are accessed through the LAN and HAFM server. The LAN interface can be: • Part of the customer’s public 10/100 Mbps LAN segment that provides access to managed switches. This switch-to-HAFM server LAN connection is part of the equipment rack installation and is required. Connection of remote workstations through the hub is optional.
General InformationI • Part of a second HAFM server interface that connects to a customer’s private intranet and allows operation of the product manager application from remote user PCs or workstations. Connection to this LAN segment is optional and depends on customer requirements. A network configuration using both Ethernet connections is shown in Figure 1–7.
General InformationI • Desktop or notebook PC with color monitor, keyboard, and mouse, using an Intel Pentium® processor with a 400 MHz or greater clock speed, and using the Microsoft Windows® 95, Windows® 98, Windows® 2000, Windows XP, or Linux 2.2 operating system. • UNIX workstation with color monitor, keyboard, and mouse, using a: — Hewlett-Packard® HA PA-RISC® processor with a 400 MHz or greater clock speed, using the HP-UX® 11 or higher operating system.

General InformationI SFP Transceivers A single-mode or multi-mode fiber-optic cable attaches to a port through a pluggable small form factor (SFP) transceiver. The SFP provides a duplex LC interface, and can be detached from the switch port for easy replacement. Two fiber-optic transceiver types are available: • Shortwave laser—Shortwave laser SFPs provide short-distance connections (2 to 500 meters) through 50-micron or 62.5-micron multi-mode fiber.
General InformationI • RS-232 maintenance port. Initial Machine Load Button When the IML button (Figure 1–8) is pressed and held for three seconds, the switch performs an IML that takes approximately 30 seconds and resets the: • Microprocessor and functional logic for the CTP card and loads firmware from FLASH memory. • Ethernet LAN interface, causing the connection to the HAFM server to drop momentarily until the connection automatically recovers.
General InformationI FRU Status LEDs Amber and green LEDs associated with switch FRUs provide status information as follows: • Port SFP - Amber and green LEDs to the left of the port (Figure 1–8) illuminate, extinguish, or blink to indicate various port states (operational with active Fibre Channel traffic, operational but not communicating, beaconing, blocked, failed, inactive, or running diagnostics).
General InformationI • E-mail messages or call-home reports from the HAFM server provide automatic notification of significant system events to designated support personnel or administrators. HAFM Diagnostics The HAFM application provides a Java-based GUI to manage, monitor, and isolate problems for multiple switches and multi-switch fabrics. The user interface operates locally on the HAFM server, or through an Ethernet LAN connection from a remote user workstation.
General InformationI Figure 1–10: Product View HAFM Status Symbols A status bar at the bottom of the Product View displays a colored symbol that indicates the worst-case status of any managed product in the Product View, that fabrics are persisted in the Fabrics View (double-click the Fabrics tab), and the status of the HAFM server. Table 1–1 illustrates and explains the meaning of the status symbols.
General InformationI A label below each icon identifies the switch by its configured name or IP address, and a colored status symbol beside each icon indicates the operational status of the switch. Table 1–1: Status Symbols Alert Symbol Green circle Meaning Status Bar: All managed products are fully operational and no failures are indicated. Next to Icon: The switch is fully operational and no failures are indicated. Yellow triangle Status Bar: At least one managed product is operating in degraded mode.

If a menu option contains a check box, click in the box to add a check mark and enable a function. Click a check box containing a check mark to remove the check mark and disable the function.
General InformationI • Observe the operational status and state, name, description, and location for the selected switch at the status table at the top of the Hardware View. • Observe green and amber LEDs that illuminate on graphical FRUs. These LEDs emulate LED operation on corresponding switch FRUs. • Observe graphical FRUs that emulate the hardware configuration and operational status of the corresponding switch. Colored symbols appear on graphical FRUs to represent failed or degraded status.
General InformationI • Online - when the switch is set online, an unblocked port and all unbypassed ports are awaiting device login and are able to attach to a device. This state is configured through the Set Online State dialog box or following an IML. • Offline - when the switch is set offline, all ports are offline and cannot accept a login from an attached device that requires a switch connection. This state is configured through the Set Online State dialog box.
General InformationI • Attention indicator - a yellow triangle overlaying the top of a port SFP indicates the port is in a nonstandard mode or configuration, but did not actually fail. The indicator appears for any port having a state other than online, failed, blocked, bypassed, or loss of light. The indicator also appears to indicate a link incident (LIN) alert or a segmented port.
General InformationI Figure 1–12: Hardware View In the Hardware View, colored indicators reflect the status of actual LEDs on the switch FRUs. The status bar displays a symbol to represent the most degraded status currently reported by any of the switch FRUs. For example, for a port failure, indicated by a blinking red and yellow diamond on a port, a yellow triangle displays on the status bar to indicate a degraded condition.

The selected fabric’s name displays above the icons at the top of the tab. Zone Set Tab This tab displays the currently active zone set for fabrics that you select from the left side of the view. The zones and zone members that make up the zone set display in a scrollable tree structure below the name of the active zone set.
General InformationI The user interface consists of the HAFM Services window (Figure 1–19), which provides HAFM application status and diagnostic information. The HAFM Services window consists of: • An event table that displays HAFM Services events that occurred since the HAFM application was started. • A status line at the bottom of the panel that provides a status indicator and message area.
General InformationI • Viewed - this column provides a check box associated with each event. Each check box allows service personnel to mark an event as viewed (acknowledged with appropriate action taken). • Date/Time - the date and time the event was reported to the HAFM server. • Product - the product associated with the event. Some events are associated with the HAFM application, while others are associated with a specific instance of the product manager application.
General InformationI Embedded Web Server Diagnostics If the hp StorageWorks ha-fabric manager (HAFM) server access is not available, the embedded web server interface provides a GUI accessed through the Internet (locally or remotely) to manage, monitor, and isolate problems for a single switch. This interface is available with switch firmware Version 1.2 (or later) installed, and does not replace nor offer the full management capability of the HAFM and switch product manager applications.
General InformationI — Upgrade switch firmware. General tasks performed through the web server interface are similar in form and function to tasks performed through the HAFM and product manager applications, and are therefore not documented in this publication. For task information and descriptions, open the online user documentation (Help selection) that supports the interface. This publication provides instructions for switch installation and fault isolation using the embedded web server interface.
General InformationI For additional information, refer to the hp StorageWorks SNMP reference guide for director 2/64, edge switch 2/16, and edge switch 2/32 (A6534-96026/AA-RQ7BB-TE).
