edge switch 2/24 service manual 1–1

General InformationI
The HP StorageWorks Edge Switch 2/24 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. The switch implements Fibre
Channel technology that provides a bandwidth of 2.125 gigabits per second, redundant
switched data paths, a scalable number of active ports, and long transmission distances
(up to 35 kilometers).
Switch Description
The Edge Switch 2/24 provides Fibre Channel connectivity through 24 generic mixed
ports (GX_Ports). Switch ports operate at either 1.0625 or 2.125 gigabits per second
(Gbps), and can be configured as:
• Fabric ports (F_Ports) to provide direct connectivity for up to 24 switched fabric
devices.
• Fabric loop ports (FL_Ports) to provide arbitrated loop connectivity and fabric
attachment for FC-AL devices. Each FL_Port can theoretically support the
connection of 126 FC-AL devices.
• Expansion ports (E_Ports) to proved interswitch link (ISL) connectivity to fabric directors
and switches.
The switch can be installed on a table or desk top, or mounted in an equipment cabinet
or in any standard equipment rack.

1–2 edge switch 2/24 service manual
General InformationI
The switch, shown in Figure 1–1, provides dynamic switched connections for servers
and devices, supports mainframe and open-systems interconnection (OSI) computing
environments, and provides data transmission and flow control between device node
ports (N_Ports) as dictated by the Fibre Channel Physical and Signaling Interface
(FC-PH 4.3). Through interswitch links (ISLs), the switch can connect additional
switches to form a Fibre Channel multi-switch fabric.
Figure 1–1: Edge Switch 2/24 (front view)
The switch provides connectivity for devices manufactured by multiple original
equipment manufacturers (OEMs). To determine if an OEM product can communicate
through connections provided by the switch, or if communication restrictions apply,
refer to the supporting publications for the product or contact your HP marketing
representative.

General InformationI
Maintenance Approach
Whenever possible, the maintenance approach instructs service personnel to perform
fault isolation and repair procedures without degrading or interrupting operation of the
switch, attached devices, or associated applications. Switch fault isolation begins
when one or more of the following occur:
• 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.
• Notification of a significant system event is received at a designated support
center through an e-mail message or the call-home feature.
System events can be related to one of the following:
• Switch or HAFM server failure (hardware or software).
• Ethernet LAN communication failure between the switch and HAFM server
• Link failure between a port and attached device.
• ISL failure or segmentation of an E_Port.
Fault isolation and service procedures vary depending on the system event information
provided. Fault isolation and related service information is provided through
maintenance analysis procedures (MAPs) documented in Chapter 3. MAPs consist of
step-by-step procedures that prompt service personnel for information or describe a
specific action to be performed. MAPs provide information to interpret system event
information, isolate a switch failure to a single FRU, remove and replace the failed
FRU, and verify switch operation. The fault isolation process normally begins with
"MAP 0000: Start MAP" on page 2-6.
Ensure the correct switch is selected for service (if the HAFM server manages
multiple switches or other HA Fabric Directors and Edge Switches) by enabling unit
beaconing at the failed switch. The amber system error LED on the switch front panel
blinks when beaconing is enabled. Instructions to enable beaconing are incorporated
into MAP steps.

General InformationI
Tools and Test Equipment
This section describes tools and test equipment that may be required to install, test,
service, and verify operation of the switch and attached HAFM server.
Tools Supplied with the Switch
The following tools are supplied with the switch. Use of the tools may be required to
perform one or more installation, test, service, or verification tasks. These tools are
supplied with the switch or must be supplied by service personnel.
• Fiber-optic loopback plug - An SFP multi-mode (shortwave laser) or single-mode
(longwave laser) loopback plug is required to perform port loopback diagnostic
tests. One loopback plug is shipped with the switch, depending on the type of port
transceivers installed. Both plugs are shipped if shortwave laser and longwave
laser transceivers are installed. The plug is shown in Figure 1–2.
Figure 1–2: Multi-mode and Single-mode Loopback Plugs
•Fiber-optic protective plug - For safety and port transceiver protection,
fiber-optic protective plugs must be inserted in all port SFPs without fiber-optic
cables attached. The switch is shipped with protective plugs installed in all ports.
A protective plug is shown in Figure 1–3.
Figure 1–3: Fiber-Optic Protective Plug

General InformationI
•Null modem cable - An asynchronous RS-232 null modem cable is required to
configure switch network addresses and acquire event log information through the
maintenance port. The cable has nine conductors and DB-9 male and female
connectors. A null modem cable is not a standard (straight-through) RS-232 cable.
Refer to Figure 1–4.
Figure 1–4: Null Modem Cable
Tools Supplied by Service Personnel
The following tools are expected to be supplied by service personnel performing
switch installation and maintenance actions. Use of the tools may be required to
perform one or more installation, test, service, or verification tasks.
•Scissors or pocket knife - A sharp cutting edge (scissors or knife blade) may be
required to cut the protective strapping when unpacking the switch, HAFM server,
Ethernet hub, or replacement FRUs.
•Standard flat-tip and cross-tip (Phillips) screwdrivers - Screwdrivers are
required to remove, replace, adjust or tighten various connector or chassis
components, and to remove and replace power supplies.
•Maintenance terminal (desktop or notebook PC) - the PC is required to
configure switch network addresses and acquire event log information through the
maintenance port. The PC must have:
— The Microsoft Windows 98, Windows 2000, or Windows Millennium Edition
operating system installed.
— RS-232 serial communication software (such as ProComm Plus™ or
HyperTerminal) installed. HyperTerminal is provided with Windows
operating systems.
•Fiber-optic cleaning kit - The kit contains tools and instructions to clean
fiber-optic cable, connectors, loopback plugs, and protective plugs.
