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. 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).

This chapter describes the switch and attached hp StorageWorks ha-fabric manager
(HAFM) server. The chapter specifically discusses:

• Switch management, error-detection and reporting features, serviceability
features, zoning, multi-switch fabrics, and specifications.

• The HAFM server and minimum hardware specifications.

• Remote workstation configurations and hardware specifications.

• Maintenance approach.

• Field-replaceable units (FRUs).

• Connectors and indicators.

• Software diagnostic features.

• Tools and test equipment.

Switch Description

The switch can be installed on a table or desk top, or mounted in an equipment cabinet
or in any standard equipment rack.

edge switch 2/16 service manual 1–1

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.

Figure 1–1: Switch, HAFM server, and Ethernet Hub

The switch 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.

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 Hewlett Packard
marketing representative

1–2 edge switch 2/16 service manual

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.

Operators at remote workstations can connect to the HAFM server through the
local HAFM application and associated Product Manager applications to manage
and monitor switches controlled by the HAFM server. A maximum of nine
concurrent users (including a local user) can log in to the HAFM application.

• Management using simple network management protocol (SNMP). An SNMP
agent is implemented through the HAFM application that allows administrators
on SNMP management workstations to access product management information
using any standard network management tool. Administrators can assign Internet
Protocol (IP) addresses and corresponding community names for up to six SNMP
workstations functioning as SNMP trap message recipients.

• Management through the Internet using the EWS interface installed on the switch.
This interface supports configuration, statistics monitoring, and basic operation of
the product, but does not offer all the capabilities of the corresponding Product
Manager application. Administrators launch the web server interface from a
remote PC by entering the product’s IP address as the Internet uniform resource
locator (URL), then entering a user name and password at a login screen. The PC
browser then becomes a management console.

General InformationI

• Management through a customer-supplied remote workstation communicating
with the HAFM server through a corporate intranet.

• Management through the command line interface (CLI). The CLI allows you to
access many HAFM and Product Manager applications while entering commands
during a telnet session with the switch. The primary purpose of the CLI is to
automate management of a large number of switches using scripts. The CLI is not
an interactive interface; no checking is done for pre-existing conditions and no
prompts display to guide users through tasks. Refer to the hp StorageWorks CLI

reference guide for director 2/64, edge switch 2/16, and edge switch 2/32

(A6534-96027/AA-RQ7AB-TE).

Figure 1–2 illustrates an example of out-of-band product management. In the figure,

the managed product is an edge switch 2/16.

Figure 1–2: Out-of-Band Product Management

The following inband management access methods are provided as options:

• Management through the product’s open-system management server (OSMS) that
communicates with an application client. The application resides on an
open-systems interconnection (OSI) device attached to a switch port, and
communicates using Fibre Channel common transport (FC-CT) protocol. Product
operation, port connectivity, zoning, and fabric control are managed through a
device-attached console.

• Management through the product’s Fibre Connection (FICON) management
server (FMS) that communicates with the IBM System Automation for OS/390
(SA OS/390) operating system. The operating system resides on an IBM
System/390

or zSeries 900 Parallel Enterprise Server attached to a director or
switch port, and communicates through a FICON channel. Control of connectivity
and statistical product monitoring are provided through a host-attached console.

Error-Detection, Reporting, and Serviceability Features

The switch provides the following error-detection, reporting, and serviceability
features:

• Light-emitting diodes (LEDs) on switch FRUs and adjacent to Fibre Channel
ports that provide visual indicators of hardware status or malfunctions.

• System and threshold alerts, event logs, audit logs, link incident logs, threshold
alert logs, and hardware logs that display switch, Ethernet link, and Fibre Channel
link status at the HAFM server or on a remote workstation.

edge switch 2/16 service manual 1–5

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.

• An internal modem in the HAFM server for HP call-home support

NOTE: For directors and switches installed in some legacy environments, call-home
notification requires installation of HP Proactive Service software. This service is offered at no
additional charge for subsystems covered under an on-site warranty or on-site storage
hardware support contract. To register or order Proactive Service software, contact your HP
customer service representative.

• An RS-232 maintenance port at the rear of the switch (port access is password
protected) that enables installation or service personnel to change the switch’s
internet protocol (IP) address, subnet mask, and gateway address; or to run
diagnostics and isolate system problems through a local or remote terminal.

• Redundant FRUs; (small form factor pluggable (SFP)) optical transceivers, power
supplies, and cooling fans that are removed or replaced without disrupting switch
or Fibre Channel link operation.

• A modular design that enables quick removal and replacement of FRUs without
tools or equipment.

• Concurrent port maintenance. SFPs and Fiber-optic cables are removed and
attached to ports without interrupting other ports or switch operation.

• Beaconing to assist service personnel in locating a specific port or switch. When
port beaconing is enabled, the amber LED associated with the port flashes. When
unit beaconing is enabled, the system error indicator on the front panel flashes.
Beaconing does not affect port or switch operation.

• Data collection through the product manager application to help isolate system
problems. The data includes a memory dump file and audit, hardware, and
engineering logs.

• Status monitoring of redundant FRUs and alternate Fibre Channel data paths to
ensure continued switch availability in case of failover. The HAFM application
queries the status of each backup FRU daily. A backup FRU failure is indicated by
an illuminated amber LED.

1–6 edge switch 2/16 service manual

• 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.

• SNMP management using the Fibre Channel Fabric Element MIB, transmission

control protocol/internet protocol (TCP/IP) MIB-II definition (RFC 1213), and a
product-specific MIB, all of which run on each switch. Up to 12 authorized
management workstations can be configured through the product manager
application to receive unsolicited SNMP trap messages. The trap messages
indicate switch operational state changes and failure conditions.

NOTE: For more information about SNMP support provided by Hewlett Packard products, 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).

Zoning Feature

The switch supports a name server zoning feature that partitions attached devices into
restricted-access groups called zones. Devices in the same zone can recognize and
communicate with each other through switched port-to-port connections. Devices in
separate zones cannot communicate with each other.

General InformationI

Zoning is configured by authorizing or restricting access to name server information
associated with device N_Ports that attach to switch fabric ports (F_Ports). A zone
member is specified by the port number to which a device is attached, or by the
eight-byte (16-digit) worldwide name (WWN) assigned to the host bus adapter (HBA)
or Fibre Channel interface installed in a device. A device can belong to multiple
zones.

CAUTION: If zoning is implemented by port number, a change to the switch fiber-optic
cable configuration disrupts zone operation and may incorrectly include or exclude a
device from a zone.

If zoning is implemented by WWN, removal and replacement of a device HBA or Fibre
Channel interface (thereby changing the device WWN) disrupts zone operation and
may incorrectly include or exclude a device from a zone.

In Open Fabric mode, only zoning by WWN is supported. Zoning by port numbers is
not.

Zones are grouped into zone sets. A zone set is a group of zones that is enabled
(activated) or disabled across all switches in a multi-switch fabric. Only one zone set
per fabric can be enabled at one time.

edge switch 2/16 service manual 1–7

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. Subject to zoning restrictions,
devices attached to any interconnected switch can communicate with each other
through the fabric.

Because a multi-switch fabric is typically complex, maintenance personnel should be
aware that several factors can degrade fabric performance or cause connectivity
failures. These factors include:

• Domain ID assignment - Each switch in a fabric is identified by a unique domain
ID that ranges from 1 through 31. A domain ID of 0 is invalid. If two operational
fabrics join, they determine if any domain ID conflicts exist between the fabrics.
If one or more conflicts exist, the E_Ports that form the interswitch link (ISL)
segment to prevent the fabrics from joining.

• Zoning - In a multi-switch fabric, zoning is configured on a fabric-wide basis, and
any change to the zoning configuration is applied to all switches in the fabric. To
ensure zoning is consistent across a fabric, the following rules are enforced when
two fabrics (zoned or unzoned) join:

— Fabric A unzoned and Fabric B unzoned - The fabrics join successfully,

and the resulting fabric remains unzoned.

— Fabric A zoned and Fabric B unzoned - The fabrics join successfully, and

fabric B automatically inherits the zoning configuration from fabric A.

— Fabric A unzoned and Fabric B zoned - The fabrics join successfully, and

fabric A automatically inherits the zoning configuration from fabric B.

— Fabric A zoned and Fabric B zoned - The fabrics join successfully only if

the zone configurations can be merged. If the fabrics cannot join, the
connecting ports segment and the fabrics remain independent.

Zone configurations for two fabrics are compatible (the zones can join) if the
active zone set name is identical for each fabric, and if zones with the same name
have identical elements.

• Port segmentation - When an ISL activates, the switches exchange operating
parameters to determine if they are compatible and can join to form a single
fabric. If incompatible, the connecting E_Port at each switch segments to prevent

1–8 edge switch 2/16 service manual

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.

— Duplicate domain IDs - one or more domain ID conflicts are detected.
— Incompatible zoning configurations - zoning configurations for the

switches are not compatible.

— Build fabric protocol error - a protocol error is detected during the process

of forming the fabric.

— No principal switch - no switch in the fabric is capable of becoming the

principal switch.

NOTE: At least one director or switch in a multi-switch fabric must be set to either principal or
default, making it capable of becoming principal switch. If all directors and switches are set to
never principal, all ISLs will segment (Reason code 05).

— Unresponsive switch - Each switch in a fabric periodically verifies operation

of all attached switches. An ISL segments if the attached switch does not
respond to a verification request.

— ELP retransmission failure timeout-a switch that exhibits a hardware

failure or connectivity problem cannot transmit or receive Class F frames. The
switch did not receive a response to multiple exchange link protocol (ELP)
frames, did not receive a fabric login (FLOGI) frame, and cannot join an
operational fabric.

HAFM Server Description

The HAFM server (Figure 1–1) is a notebook personal computer (PC) that provides a
central point of control for up to 48 LAN-connected directors or edge switches.

edge switch 2/16 service manual 1–11

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.

The HAFM server provides an auto-detecting 10/100 Mbps LAN connection,
provided by an internal Ethernet adapter card. This LAN port attaches to the
customer’s public intranet to allow access from remote user workstations. An optional
Ethernet adapter card (not supplied by HP) can be installed in the personal computer
memory card international association (PCMCIA) slot to provide a connection to a
private LAN segment for dedicated switch communication.

HAFM Server Specifications

The following list summarizes hardware specifications for the HAFM server notebook
platform. Current platforms may ship with more enhanced hardware, such as a faster
processor, additional random- access memory (RAM), or a higher-capacity hard drive
or removable disk drive.

• HP Omnibook 6200 PC with color monitor, keyboard, keyboard-mounted
trackpad (mouse), and U. S. power cord.

Embedded Web Server Interface

Administrators or operators with a browser-capable PC and an Internet connection can
monitor and manage the switch through an embedded web server interface. The
application provides a graphical user interface (GUI) similar to the product manager
application, and supports switch configuration, statistics monitoring, and basic
operation.

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:

edge switch 2/16 service manual 1–13

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.

• 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 a:

• 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 2-7.

Ensure the correct switch is selected for service (if the HAFM server manages
multiple switches or other Hewlett Packard products) 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.

Remote Workstation Configurations

Using a standard web browser, the HAFM and product manager applications can be
downloaded and installed on remote user workstations that are LAN-attached to the
HAFM server. Operators at these workstations can manage and monitor switches
controlled by the HAFM server. A maximum of nine concurrent users (including a
local user) can log in to the HAFM application.

1–14 edge switch 2/16 service manual

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. This type of network configuration using one Ethernet
connection through the HAFM server is shown in Figure 1–6.

This single-Ethernet connection is supported by HP, is Open View-Storage Node
Manager (OV-SNM) compatible, and is the recommended configuration for a
typical HP installation at a customer site. LAN security is provided by restricting
password access and disabling the SNMP agent, embedded Web server interface,
and command line interface (telnet access) for each managed switch.

NOTE: The Ethernet adapter in the HAFM server provides an auto-detecting 10/100 Mbps
connection. Depending on speed restrictions imposed by other LAN-attached devices, the LAN
segment that connects the HAFM server to manage directors and switches operates at either
ten or 100 Mbps.

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.

• Longwave laser—Longwave laser SFPs provide long-distance connections (up to

10 kilometers) through 9-micron single-mode fiber.

• Extended reach laser—Extended reach laser SFPs provide long-distance

connections (up to 35 kilometers) through 9-micron single-mode fiber.

Cooling Fans

Three 2-fan FRUs (a total of six fans) provide cooling for the switch power supplies
and the control processor (CTP) card, as well as redundancy for continued operation if
a single fan fails.

Each fan FRU can be replaced while the switch is operating.

General InformationI

Power Supplies

Redundant, load-sharing power supplies step down and rectify facility input power to
provide 3.3 volts direct current (VDC), 5 VDC, and 12 VDC to the CTP card. The
power supplies also provide input filtering, overvoltage protection, and overcurrent
protection. Either power supply can be replaced while the switch is operational.

Each power supply has a separate CTP card connection to allow for independent AC
power sources. The power supplies are input-rated at 100 to 230 volts alternating
current (VAC).

Connectors and Indicators

Connectors and indicators include the:

• Initial machine load (IML) button.

• Ethernet LAN connector.

• Green power (PWR) and amber system error (ERR) LEDs.

• Green and amber status LEDs associated with FRUs.

edge switch 2/16 service manual 1–19

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.

• Ports, causing all Fibre Channel connections to drop momentarily until the
connections automatically recover.

An IML should only be performed if a CTP card failure is indicated. Do not IML the
switch unless directed to do so by a procedural step or the next level of support. As a
precaution, the IML button is flush mounted to protect against accidental activation.

Ethernet LAN Connector

The front panel provides a 10/100 megabit per second (Mbps) RJ-45 twisted-pair
connector (Figure 1–8) that attaches to an Ethernet LAN to provide communication
with the HAFM server or an SNMP management workstation. Two green LEDs are
associated with the LAN connector. When illuminated, the left LED indicates LAN
operation at 10 Mbps, and the right LED indicates LAN operation at 100 Mbps.

Power and System Error LEDs

The PWR LED (Figure 1–8) illuminates when the switch is connected to facility AC
power and powered on. If the LED extinguishes, a facility power source, power cord,
or power distribution failure is indicated.

The ERR LED (Figure 1–8) illuminates when the switch detects an event requiring
immediate operator attention, such as a FRU failure. The LED remains illuminated as
long as an event is active. The LED extinguishes when the Clear System Error Light
function is selected from the product manager application. The LED blinks if unit
beaconing is enabled. An illuminated ERR LED (indicating a failure) takes
precedence over unit beaconing.

1–20 edge switch 2/16 service manual

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).

• Fan - An amber LED at the upper left corner of each fan FRU (Figure 1–9)

illuminates if the fan fails or rotates too slowly.

• Power Supply - A green LED on each power supply (Figure 1–9) illuminates if

the power supply is operational and receiving AC power.

Maintenance Port

The rear panel provides a 9-pin RS-232 maintenance port (Figure 1–9) that provides a
connection for a local terminal or dial-in connection for a remote terminal. Although
the port is typically used by authorized maintenance personnel, operations personnel
can use the port to configure switch network addresses.

General InformationI

Software Diagnostic Features

The switch provides the following diagnostic software features that aid in fault
isolation and repair of problems:

• FRUs provide on-board diagnostic and monitoring circuits that continuously

report FRU status to the HAFM and product manager applications. These
applications provide system alerts and logs that display failure and diagnostic
information at the HAFM server or a remote workstation communicating with the
HAFM server.

• The HAFM Services application that runs as a Windows 2000 service and

provides an additional user interface to display operational status.

• The embedded web server interface that provides Internet access to isolate

problems for a single switch.

• Unsolicited SNMP trap messages that indicate operational state changes or

failures can be transmitted to up to 12 authorized management workstations.

edge switch 2/16 service manual 1–21

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. The application starts automatically when the HAFM server is
powered on or rebooted, and the default display is the main HAFM window, or
Product View (Figure 1–10). If you are using a remote user workstation, see Log Into
the HAFM in the hp StorageWorks edge switch 2/16 product manager user guide
(A7284-96003/AA-RS2KA-TE). Managed products (including switches) appear as
icons in the window, and a set of view tabs appear at the top of the window. A status
bar displays below the view area of the screen.

Figures containing HAFM and product manager screens in this manual are included
for illustration purposed only. These illustrations may not match exactly what you see
through your server or workstation. Title bars have been removed from the

The switch status table displays the selected switch operational status, operational
state, port state, name, description, and location. The Status field shows one of the
following:

• Fully Operational - all switch FRUs and ports are fully operational, and no
failures are indicated.

• Redundant Failure - a redundant FRU failed (power supply or fan FRU) and the
switch is operational. In addition to the text message, the Status and State fields
change to a yellow background (refer to Figure 1–12, Hardware View).

• Minor Failure - a failure occurred that decreased the operational capability of the
switch (port SFP failure), but has not affected normal switching operations. In
addition to the text message, the Status and State fields change to a yellow
background (refer to Figure 1–12).

• Not Operational - the switch failed, is not operational, and requires immediate
service. In addition to the text message, the Status and State fields change to a
yellow background (refer to Figure 1–12).

• No Link - if the switch-to-HAFM server link is down, No Link appears in the
Status field, the Status and State fields change to a yellow background, the Name,
Description, and Location fields do not display, and the State field changes to a
Reason field with a brief description of the link loss condition. For a description
of link loss conditions, refer to MAP 0400: Loss of Console Communication on

page 2–39.

The State field shows one of the following:

1–26 edge switch 2/16 service manual

• 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.

• Coming online - this is a transitional state that occurs just prior to the switch

going online. Unless a problem occurs, this state appears only briefly. The switch
automatically transitions through this state after a power-up or reset procedure.

• Going offline - this is a transitional state that occurs just prior to the switch going

offline. Unless a problem occurs, this state appears only briefly.

LED Emulation

At the Hardware View for the selected switch, simulated LEDs illuminate on FRUs
and adjacent to port SFPs to emulate the operation of LEDs on the corresponding
hardware. Simulated PWR and ERR LEDs also illuminate to emulate the operation of
LEDs on the corresponding switch front panel. For an explanation of LED operation,
refer to FRU Status LEDs.

General InformationI

Product Manager Status Symbols

A status bar at the bottom of the window displays a colored symbol (green circle,
yellow triangle, red diamond with yellow background, or grey square) that indicates
the worst-case status of the selected switch. The meaning of the status symbol is
consistent with the icon explanations in

As an example, for a single SFP, fan, or power supply failure, a blinking red and
yellow diamond displays at the FRU illustration in the Hardware View. However, the
status bar displays a yellow triangle to indicate degraded operation. If a blinking red
and yellow diamond displays over multiple FRUs, the status bar displays a red and
yellow diamond, indicating a critical failure and the switch is not operational.

The following colored symbols overlay graphical FRUs to represent failed or
degraded status for the corresponding switch FRU.

• Failed FRU indicator - a blinking (color reversing) red and yellow diamond

overlaying a FRU indicates the FRU failed and immediate service is required.

edge switch 2/16 service manual 1–27

Each bar graph also shows the percentage link utilization for the port. A red arrow
marks the highest utilization level reached since the Performance View was opened. If
the system detects activity on a port, it represents minimal activity with at least one
bar.

When an end device (node) is logged into a port, moving the cursor over the port’s bar
graph in the Performance View highlights the graph and displays a message with the
world-wide name of the connected node. If the connected node has more than one
port, this is the world-wide name of the specific port on the node. When a port is
functioning as an expansion port (E_Port), the message is “E_Port.” When a port is
not logged into an end-device (not functioning as an F_Port) or to another switch (not
functioning as an E_Port), the message is the port’s current online state.

HAFM Services Application

The hp StorageWorks ha-fabric manager (HAFM) Services application provides both
a central control point and server-side functionality (in a client-server environment)
for all Hewlett Packard managed products. The application runs as a Windows 2000
service and starts automatically when the HAFM server is powered on.

1–38 edge switch 2/16 service manual

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.

Figure 1–19: HAFM Services Window

Event Table

The event table displays the last ten events that occurred since the HAFM application
was started. Events that occurred during a prior instance of the application do not
display. If a new event occurs while ten events display, the oldest event is discarded. A
deeper event history is maintained in the form of a log file viewed through the HAFM
application.

The events are internal error conditions detected by the HAFM application, and are
not related to product-specific events reported by a switch. Events typically relate to
HAFM audit log and file corruption, invalid product definition and firmware files,
missing product services class, or missing version information.

The event table contains the following columns:

edge switch 2/16 service manual 1–39

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. In the latter case, the switch and configured name
(or IP address) associated with the instance are displayed.

• Event - the numeric event code and a brief description of the event.

Status Line

The status line provides a status indicator and message area. HAFM status symbols
are explained in Table 1–3.

The HAFM application icon (upper left corner of the window) is dynamic and
matches the status indicator. This feature allows users and service personnel to
observe the status when the application is minimized to the Windows 2000 task bar.

The message area briefly displays messages during HAFM application startup to
indicate the progress of startup activities.

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

The embedded web server interface can be opened from a standard web browser
running Netscape Navigator

®

4.6 or higher or Microsoft Internet Explorer 4.0 or
higher. At the browser, enter the IP address of the switch as the Internet uniform
resource locator (URL). When prompted at a login screen, enter a user name and
password. When the interface opens, the default display is the View panel. Service
personnel can perform the monitoring, configuration, maintenance and diagnostic
functions as follows:

• View panel - quickly inspect and determine the operational status of the switch,

and inspect switch properties and operating parameters, FRU properties, and Fibre
Channel port properties.

• Configure panel - configure or change:

— Switch ports.
— Switch identification, date and time, operating parameters, and network

addresses.
— SNMP trap message recipients.
— User passwords.

• Monitor panel - inspect and monitor:

— Fibre Channel ports and port performance statistics.
— The active zone set.
— Event log entries, and clear the IML LED at the front panel.
— Information about attached devices (nodes).

• Operations panel - perform the following operations and maintenance tasks:

— Enable port beaconing and perform port diagnostics (internal and external

loopback tests).
— Reset Fibre Channel ports.
— Set the switch online state.

edge switch 2/16 service manual 1–41

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. Refer to the hp StorageWorks edge switch 2/16
installation guide, (A7284-96001/AA-RSU2A-TE) for installation and configuration
tasks. Refer to Chapter 2 for fault isolation tasks.

SNMP Trap Message Support

Unsolicited SNMP trap messages that indicate switch operational state changes or
failure conditions can be customer-configured to be transmitted to up to 12
management workstations. If installed on a dedicated Ethernet LAN, the workstations
communicate directly with each switch. If installed on a customer intranet, the
workstations communicate with switches through the HAFM server.

SNMP data and trap messages are defined in the Fibre Channel FE-MIB definition, a
subset of the TCP/IP MIB-II definition (RFC1213), and a custom, switch-specific
MIB. Customers can install these MIBs (in standard ASN.1 format) on any SNMP
management workstation.

Although SNMP trap messages are typically transmitted to customer personnel only,
the messages may be provided to service personnel as initial notification of a switch
problem or as information included in the fault isolation process. Generic SNMP traps
include:

• coldStart - reports that the SNMP agent is reinitializing due to a switch reset.

• warmStart - reports that the SNMP agent is reinitializing due to a switch IPL.

• authorizationFailure - reports access by an unauthorized SNMP manager. This

trap is configurable, and is disabled by default.

Switch-specific SNMP traps specified in the custom MIB include Fibre Channel port
operational state changes and FRU operational state changes.

If authorized through the Configure SNMP dialog box in the product manager
application, users at SNMP management workstations can modify MIB variables.
Switch modifications performed through SNMP management work stations are
recorded in the associated switch Audit Log and are available through the product
manager application.

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).

E-Mail and Call-Home Support

If e-mail notification and call-home support are configured for the switch as part of
the customer support process, service personnel may be:

• Notified of a switch problem by e-mail message, either directly or through a
system administrator at the customer site or call center.

edge switch 2/16 service manual 1–45

This chapter describes diagnostic procedures used by service representatives to isolate
hp StorageWorks edge switch 2/16 (edge switch 2/16) problems or failures to the
field-replaceable unit (FRU) level. The chapter specifically describes how to perform
maintenance analysis procedures (MAPs).

Maintenance Analysis Procedures

The MAPs provide fault isolation and related service procedures. They are
step-by-step procedures that prompt service personnel for information and describe a
maintenance action. They provide information to interpret system events, isolate a
switch failure to a single FRU, remove and replace the failed FRU, and verify switch
operation.

Factory Defaults

Table 2–1 lists the defaults for the passwords, and IP, subnet, and gateway addresses.

When the switch is powered on, it performs a series of power-on self-tests (POSTs).
When POSTs complete, the switch performs an initial program load (IPL) that loads
firmware and brings the unit online. This MAP describes fault isolation for problems
that may occur during the POST/IPL process.

If an error is detected, the POST/IPL process continues in an attempt to initialize the
switch and bring it online. But an event code 400 displays when the switch completes
