Switch LEDs and controls

The switch LEDs provide information about the switch’s operational status. These LEDS include the Input Power LED (green), Heartbeat LED (green), and the System Fault LED (amber) (Figure 2). For information about port LEDs, see ”Port LEDs” on page 14. The Maintenance button (Figure 2) is the only switch control. It is used to reset a switch or to recover a disabled switch. To apply power to the switch, plug the power cord into the switch AC power receptacle, located on the back of the switch, and into a 100–240 VAC power source.

1 Input Power LED (green) 2 Heartbeat LED (green)

3 System Fault LED (amber) 4 Maintenance button

Figure 2 Switch LEDs and controls

Input power LED (green)

The Input Power LED indicates the voltage status at the switch logic circuitry. During normal operation, this LED illuminates to indicate that the switch logic circuitry is receiving the proper DC voltages. When the switch is in maintenance mode, this LED is extinguished.

Heartbeat LED (green)

The Heartbeat LED indicates the status of the internal switch processor and the results of the POST. Following a normal power-up, the Heartbeat LED blinks about once per second to indicate that the switch passed the POST and that the internal switch processor is running. In maintenance mode, the Heartbeat LED illuminates continuously. For more information, see ”Heartbeat LED blink patterns” on page 48.

System fault LED (amber)

The System Fault LED illuminates to indicate that a fault exists in the switch firmware or hardware. Fault conditions include POST errors, over-temperature conditions, and power supply malfunctions. The Heartbeat LED shows a blink code for POST errors and over-temperature conditions. For more information, see ”Heartbeat LED blink patterns” on page 48.

Maintenance button

The Maintenance button (Figure 2) is a dual-function momentary switch on the front panel. Its purpose is to reset the switch or to place the switch in maintenance mode. Maintenance mode sets the IP address to

10.0.0.1 and provides access to the switch for maintenance purposes when flash memory or the resident configuration file is corrupted. For more information, see ”Recovering a switch using maintenance mode” on page 53.

Resetting a switch

To reset the switch, press and hold the Maintenance button with a pointed tool for less than 2 seconds. The switch will respond as follows:

1. All the switch LEDs will illuminate except the System Fault LED.

2. After approximately 1 minute, the power-on self test (POST) begins, extinguishing the Heartbeat LED.

3. When the POST is complete, the Input Power LED is illuminated and the Heartbeat LED is flashing once

per second.

Placing the switch in maintenance mode

To place the switch in maintenance mode:

1. Isolate the switch from the fabric.

2. Press and hold the Maintenance button with a pointed tool for a few seconds until only the Heartbeat

LED (Figure 2) is illuminated. Continue holding the maintenance button until the Heartbeat LED goes off, then release the button. The Heartbeat LED illuminates continuously while the switch is in maintenance mode.

To exit maintenance mode and return to normal operation, press and release the Maintenance button momentarily to reset the switch.

The 8/20q Fibre Channel Switch has twenty Fibre Channel ports. Ports are numbered 0–19 (Figure 3). Each of the ports is served by a Small Form-Factor Pluggable (SFP+) transceiver and is capable of 8-Gb/s, 4-Gb/s, or 2-Gb/s transmission.

• SFPs are hot-pluggable.

• User ports can self-discover both the port type and transmission speed when connected to devices or

other switches.

• The port LEDs are located above ports 0–9 and below ports 10–19, and provide port login and activity

status information.

NOTE: Setting a Fibre Channel port that has an 8-Gb/s SFP transceiver to 1-Gb/s will down the port.

Figure 3 Fibre Channel ports

The 8/20q Fibre Channel Switch comes from the factory as an 8- or 16-port switch, enabling ports 0–7 or 0–15 respectively. You can enable additional ports up to the 20-port maximum using the HP StorageWorks 8/20q 4-port Upgrade License. For more information, see ”Installing feature license keys” on page 42.

Port LEDs

Each port has its own Logged-in LED (green) and Activity LED (green) (Figure 4).

1 Logged-in LED (port 0) 2 Activity LED (port 0)

3 Activity LED (port 10) 4 Logged-in LED (port 10)

Figure 4 Port LEDs

Port Logged-in LED (green)

The Logged-in LED indicates the logged-in or initialization status of the connected devices. After successful completion of the POST, the switch extinguishes all Logged-in LEDs. Following a successful port login, the switch illuminates the corresponding logged-in LED. This shows that the port is properly connected and able to communicate with its attached devices. The Logged-in LED remains illuminated as long as the port is initialized or logged in. If the port connection is broken or an error occurs that disables the port, the

Logged-in LED is extinguished. For more information, see ”Logged-in LED indications” on page 50.

Port Activity LED (green)

The Activity LED indicates that data is passing through the port. Each frame that the port transmits or receives illuminates this LED for 50 milliseconds. This makes it possible to observe the transmission of a single frame.

Transceivers

The 8/20q Fibre Channel Switch supports SFP+ optical transceivers for the Fibre Channel ports. A transceiver converts electrical signals to and from optical laser signals to transmit and receive data. Duplex fiber optic cables plug into the transceivers which then connect to the devices. A port is capable of transmitting at 8 Gb/s, 4 Gb/s, or 2 Gb/s; however, the transceiver must also be capable of delivering at this rate.

The SFP+ transceivers are hot-pluggable. This means that you can remove or install a transceiver while the switch is operating without harming the switch or the transceiver. However, communication with the connected device will be interrupted. For information about installing and removing SFP+ optical transceivers, see ”Install the transceivers” on page 35.

Port types

The 8/20q Fibre Channel Switch supports generic ports (G_Port, GL_Port), fabric ports (F_Port, FL_Port), expansion ports (E_Port), and transparent routing ports (TR_Port). Switches come from the factory with all Fibre Channel ports configured as GL_Ports. Table 2 describes generic, fabric, expansion, and transparent routing port functions.

loop device, as an F_Port when connected to a single device, or as an E_Port when connected to another switch. If the device is a single device on a loop, the GL_Port will attempt to configure first as an F_Port, then if that fails, as an FL_Port.

G_Port Generic port—self-configures as an F_Port when connected to a single

device, or as an E_Port when connected to another switch.

FL_Port Fabric loop port—supports a loop of up to 126 devices. An FL_Port can

also configure itself during the fabric login process as an F_Port when connected to a single device (N_Port).

F_Port Fabric port—supports a single device.

E_Port Expansion port—expands the fabric by connecting 8/20q Fibre

Channel Switches. The 8/20q Fibre Channel Switch self-discovers all inter-switch connections. For more information, see ”Multiple switch

fabrics” on page 21.

TR_Port Transparent routing port—expands the fabric by connecting an 8/20q

Fibre Channel Switch to an HP StorageWorks B-series or C-Series remote fabric. The TR_Port provides transparent communication between local fabric devices and remote fabric devices while maintaining separate fabrics. For more information, see ”Transparent routing” on page 23.

Ethernet port

The Ethernet port is an RJ-45 connector that provides a connection to a workstation through a 10/100 Base-T Ethernet cable (Figure 5). A workstation can be a Windows configure and manage the switch fabric. An Ethernet connection to the switch is required to manage the switch using the CLI, QuickTools, Simple SAN Connection Manager, or Simple Network Management Protocol (SNMP).

The Ethernet port has two LEDs: the Link Status LED (green) and the Activity LED (green). The Link Status LED illuminates continuously when an Ethernet connection has been established. The Activity LED illuminates when data is being transmitted or received over the Ethernet connection.

Power supply and fans

The switch has a single power supply that converts 100–240 VAC to DC voltages for the various switch circuits. Four internal fans provide cooling. The switch monitors internal air temperature, and therefore does not monitor or report fan operational status. Air flow is front-to-back. To energize the switch, plug the power cord into the switch AC receptacle (located on the back of the switch) and into a 100–240 VAC power source.

Switch management

The switch supports the following management tools and protocols:

• QuickTools web applet, page 18

• Simple SAN Connection Manager, page 18

• Command line interface, page 18

• Simple Network Management Protocol, page 18

• Storage Management Initiative–Specification (SMI-S), page 18

• File transfer protocols, page 18

8/20q Fibre Channel Switch Installation and Reference Guide 17

QuickTools web applet

QuickTools is a browser-based graphical user interface (GUI) that provides switch management capabilities beyond those of Simple SAN Connection Manager. You run QuickTools by opening the switch IP address with an internet browser on your workstation. See the HP StorageWorks 8/20q Fibre Channel Switch QuickTools Switch Management User Guide. QuickTools provides the following management features:

• Faceplate device management

• Switch and port statistics

• Configuration wizard

• Zoning administration

• Fabric tree for fabric management

• User account configuration

• Switch and fabric events

• Operational and environmental statistics

• Global device nicknames

• Inband management of other switches in the fabric

• Online help

Simple SAN Connection Manager

HP StorageWorks Simple SAN Connection Manager is a GUI-based management application for HP StorageWorks that runs on a workstation known as the management station. It provides basic automated configuration and management of switches, HBAs, and storage devices.

Command line interface

The command line interface (CLI) provides monitoring and configuration functions by which the administrator can manage the fabric and its switches. The CLI is available over an Ethernet connection or a serial connection. For more information, see the HP StorageWorks 8/20q Fibre Channel Switch Command Line Interface Guide.

Simple Network Management Protocol

SNMP provides monitoring and trap functions for the fabric. The switch firmware supports SNMP versions 1, 2, and 3, the Fibre Alliance Management Information Base (FA-MIB) version 4.0, and the Fabric Element Management Information Base (FE-MIB) RFC 2837. Traps can be formatted using SNMP version 1 or 2. SNMP version 3 provides secure access to devices through a combination of authentication and encryption. You can enable SNMP, configure SNMP traps, and configure SNMP version 3 security using the command line interface or QuickTools.

Storage Management Initiative–Specification (SMI-S)

SMI-S provides for the management of the switch through third-party applications that use the SMI-S. For more information, see the HP StorageWorks 8/20q Fibre Channel Switch CIM Agent Reference Guide.

File transfer protocols

FTP and TFTP provide the command line interface for exchanging files between the switch and the workstation. These files include firmware image files, configuration files, and log files. For more information about FTP and TFTP, see the HP StorageWorks 8/20q Fibre Channel Switch Command Line Interface Guide.

2 Planning

Consider the following when planning a fabric:

• Devices, page 19

• Device access, page 19

• Performance, page 20

• Feature licenses, page 21

• Multiple switch fabrics, page 21

• Switch services, page 24

• Security, page 26

• Fabric management, page 28

Devices

When planning a fabric, consider the following:

• The number of devices and the anticipated demand. This will determine the number of ports that are

needed and in turn the number of switches.

• The transmission speeds of your HBAs and SFPs. The switch supports 2-Gb/s, 4-Gb/s and 8-Gb/s

transmission speeds.

IMPORTANT: Setting a Fibre Channel port that has an 8-Gb/s SFP transceiver to 1-Gb/s will down the

port.

• The distribution of targets and initiators. An F_Port supports a single device. An FL_Port can support up

to 126 devices in an arbitrated loop.

Device access

Consider device access needs within the fabric. Access is controlled by the use of zoning. Some zoning strategies include the following:

• Separating devices by operating system

• Separating devices that have no need to communicate with other devices in the fabric or have

classified data

• Separating devices into department, administrative, or other functional group

Zoning divides the fabric for purposes of controlling discovery and inbound traffic. A zone is a named group of ports or devices. Members of the same zone can communicate with each other and transmit outside the zone, but cannot receive inbound traffic from outside the zone. Zoning is hardware-enforced only when a port/device is a member of no more than eight zones whose combined membership does not exceed 64. If this condition is not satisfied, that port behaves as a soft zone member. You can assign ports/devices to a zone individually or as a group by creating an alias.

A zone can be a component of more than one zone set. Several zone sets can be defined for a fabric, but only one zone set can be active at one time. The active zone set determines the current fabric zoning.

8/20q Fibre Channel Switch Installation and Reference Guide 19

A zoning database is maintained on each switch. Table 4 describes the zoning database limits, excluding the active zone set.

Table 4 Zoning database limits

Limit Description

MaxZoneSets Maximum number of zone sets (256).

MaxZones Maximum number of zones (2,000).

Performance

The 8/20q Fibre Channel Switch supports class 2 and class 3 Fibre Channel service at transmission rates of 8-Gb/s with a maximum frame size of 2,148 bytes. Related performance characteristics include the following:

can be stored in the zoning database. Each instance of a zone member or alias member counts toward this maximum.

(2,000), excluding the orphan zone set. Each instance of a zone in a zone set counts toward this maximum.

• Distance, page 20

• Bandwidth, page 20

• Latency, page 21

Distance

Consider the physical distribution of devices and switches in the fabric. Choose SFP transceivers that are compatible with the cable type, distance, Fibre Channel revision level, and the device host bus adapter. For more information about cable types and transceivers, see ”Technical specifications” on page 63.

Each Fibre Channel port is supported by a data buffer with a 16 credit capacity; that is, 16 maximum sized frames. For fibre optic cables, this enables full bandwidth over approximately 3 kilometers at 8 Gb/s (4.8 credits/km).

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A Fibre Channel port can transmit or receive at nominal rates of 8 Gb/s, 4 Gb/s, or 2 Gb/s depending on the device to which it is connected. This corresponds to full duplex bandwidth values of 1,700 MB, 850 MB, and 424 MB respectively. Multiple source ports can transmit to the same destination port if the destination bandwidth is greater than or equal to the combined source bandwidth. For example, two 4 Gb/s source ports can transmit to one 8 Gb/s destination port. Similarly, one source port can feed multiple destination ports if the combined destination bandwidth is greater than or equal to the source bandwidth.

In multiple switch fabrics, each link contributes up to 1,700 MB of bandwidth between those switches, depending on the speed of the link. When additional bandwidth is needed between devices, increase the number of links between the connecting switches. The switch guarantees in-order delivery with any number of links.

Latency

Latency is a measure of how fast a frame travels through a switch from one port to another. The factors that affect latency include transmission rate and the source/destination port relationship (Table 5).

Table 5 Por t - to -port latency

Destination Rate

Gbps 2 4 8

Source Rate

4 < 0.4 μsec < 0.3 μsec < 0.4 μsec

8 < 0.3 μsec < 0.2 μsec < 0.2 μsec

Feature licenses

License keys provide a way to expand the capabilities of your switch and fabric as your needs grow. The HP StorageWorks 8/20q 4-port Upgrade License activates additional Fibre Channel ports to 12, 16, or 20 ports. Applying a license key is not disruptive, nor does it require a switch reset. To order a license key, contact your switch distributor or your authorized reseller. For more information, see ”Installing feature

license keys” on page 42.

Multiple switch fabrics

< 0.6 μsec

By connecting switches to one another, you can expand the number of available ports for devices. Each switch in the fabric is identified by a unique domain ID, and the fabric can automatically resolve domain ID conflicts. Because the Fibre Channel ports are self-configuring, you can connect 8/20q Fibre Channel Switches together in a wide variety of topologies. When planning your fabric, consider your topology and cabling requirements. Transparent routing to a legacy fabric is also possible using TR_Ports.

For more information about Storage Area Network (SAN) connectivity, see the SAN design reference guide available at the HP website: http://www.hp.com/go/SANdesignguide

The following topics describe important aspects of multiple switch fabrics:

• Optimizing device performance, page 21

• Domain ID, principal priority, and domain ID lock, page 22

• Common topologies, page 22

• Transparent routing, page 23

Optimizing device performance

When choosing a topology for a multiple switch fabric, you should also consider the proximity of your server and storage devices and the performance requirements of your application. Storage applications such as video distribution, medical record storage/retrieval, or real-time data acquisition can have specific latency or bandwidth requirements.

The 8/20q Fibre Channel Switch provides the lowest latency of any product in its class. For information about latency, see ”Performance” on page 20. However, the highest performance is achieved on Fibre Channel switches by keeping traffic within a single switch instead of relying on ISLs. Therefore, for optimal device performance, place devices on the same switch under the following conditions:

• Heavy I/O traffic between specific server and storage devices.

• Distinct speed mismatch between devices such as the following:

• An 8-Gb/s server and a slower 4-Gb/s storage device

• A high performance server and slow tape storage device

8/20q Fibre Channel Switch Installation and Reference Guide 21

Domain ID, principal priority, and domain ID lock

The following switch configuration settings affect multiple switch fabrics:

• Domain ID

• Principal priority

• Domain ID lock

The domain ID is a unique number from 1–239 that identifies each switch in a fabric. The principal priority is a number (1–255) that determines the principal switch which manages domain ID assignments for the fabric. The switch with the highest principal priority (1 is high, 255 is low) becomes the principal switch. If the principal priority is the same for all switches in a fabric, the switch with the lowest Worldwide Name (WWN) becomes the principal switch.

The domain ID lock allows (False) or prevents (True) the reassignment of the domain ID on that switch. Switches come from the factory with the domain ID set to 1, the domain ID lock set to False, and the principal priority set to 254. For information about changing the default domain ID, domain ID lock, and principal priority parameters, see the set config switch command in the HP StorageWorks 8/20q Fibre Channel Switch Command Line Interface Guide.

If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain ID conflict occurs, the new switch will isolate as a separate fabric. You can remedy this by resetting the new switch or taking it offline then putting it back online. The principal switch will reassign the domain ID and the switch will join the fabric.

NOTE: Domain ID reassignment is not reflected in zoning that is defined by domain ID/port number pair

or Fibre Channel address. You must reconfigure zones that are affected by domain ID reassignment. To prevent zoning definitions from becoming invalid under these conditions, lock the domain IDs. Domain ID reassignment has no effect on zone members defined by WWN.

Common topologies

For additional information about Storage Area Network (SAN) connectivity, see the SAN design reference guide available at the HP website: http://www.hp.com/go/SANdesignguide

Transparent routing

IMPORTANT: The Simple SAN Connection Manager (SSCM) application version 2.10 can manage

8/20q Fibre Channel Switches with active TR_Ports; however, SSCM cannot manage or discover remote switches or devices in the remote fabric. Use QuickTools and the storage management interface to present Logical Unit Numbers (LUNs) to remote devices. SSCM displays the remote fabric as a grayed-out switch, but no management can be performed. SSCM version 2.0 and earlier versions do not support the management of fabrics that include 8/20q Fibre Channel Switches with active TR_Ports and may disrupt communication between the 8/20q Fibre Channel Switch and the remote fabric. If you intend to manage the SAN using SSCM, be sure to use SSCM version 2.10 or later.

The transparent routing feature provides inter-fabric routing to allow controlled and limited access between devices on a 8/20q Fibre Channel Switch (local) fabric and devices on a remote fabric consisting of B-Series or C-Series switches. For a list of switches that are supported in a remote fabric, see the HP

StorageWorks 8/20q Fibre Channel Switch release notes, and the HP StorageWorks SAN Design reference guide located at the HP website: http://www.hp.com/go/sandesignguide

inter-fabric connection uses the Fibre Channel industry N-Port ID Virtualization (NPIV), and makes local and remote devices accessible to each other while maintaining the local and remote fabrics as separate fabrics.

You can connect multiple 8/20q Fibre Channel Switches to one or more remote fabrics using multiple TR_Ports. Local and remote devices are identified by their respective port worldwide names. Consider the following mapping rules:

. This type of

• A TR_Port can support a maximum of 32 local device/remote device mappings.

• A specific local device can be mapped to devices on only one remote fabric. Local devices on the same

8/20q Fibre Channel Switch can each be mapped to different remote fabrics.

• For mappings between a specific 8/20q Fibre Channel Switch and a remote fabric, each local device

or remote device can be mapped over only one TR_Port. Additional mappings to either device must use that same TR_Port.

• Mulitple local devices connected to different local switches can be mapped to the same remote device

over one TR_Port on each local switch.

• A local device cannot be mapped over an E_Port to another local switch, then over a TR_Port to the

remote device. The local switch to which the local device is connected must connect directly to the remote fabric over a TR_Port.

NOTE: When a local device is mapped over a TR_Port to a remote device, the local device and its

TR_Port appear as an NPIV connected device in the remote fabric. It is possible, though not recommended, to map such a local device over a second TR_Port to a local device in a second local fabric. In this case, if you merge the two local fabrics, the transparent route becomes inactive for the devices that now have a path over an ISL, and an alarm is generated.

You can configure transparent routing using QuickTools or the CLI, though QuickTools is recommended because it validates your entries, manages the zone mapping for the local fabric, and creates a list of zoning commands that can be run in a script on a HP StorageWorks B-series or C-Series SAN switch. For more information, see the HP StorageWorks 8/20q Fibre Channel Switch QuickTools Switch Management User Guide and the HP StorageWorks 8/20q Fibre Channel Switch Command Line Interface Guide.

To configure transparent routing using QuickTools:

1. Determine what devices on the local fabric require access to devices on the remote fabric. Local devices

must be attached directly to the 8/20q Fibre Channel Switch.

2. Configure one or more TR_Ports on the local 8/20q Fibre Channel Switch, and then connect the

TR_Port to the remote fabric. QuickTools prompts you to configure TR_Ports where existing port connections to remote fabrics have isolated. For remote HP StorageWorks B-series or C-Series fabrics, the switch to which the TR_Port connects must support N-Port ID Virtualization (NPIV) and for B-Series

8/20q Fibre Channel Switch Installation and Reference Guide 23

fabrics, the interoperability mode must be configured to InteropMode=0. Other B-Series or C-Series switches in the remote fabric need not support NPIV.

NOTE: Be sure to configure the TR_Port before connecting the remote fabric to the HP

StorageWorks 8/20q Fibre Channel Switch. If the remote fabric is connected to a port on the HP StorageWorks 8/20q Fibre Channel Switch that is not a TR_Port, the two fabrics may establish an E_Port connection and the local and remote fabrics may merge. This mixed fabric is not supported . If the port type is changed to TR_Port after connecting the remote fabric, a port reset may be required to completely establish the connection.

3. Map local devices to remote devices and activate the connection. The QuickTools mapping process

creates an inter-fabric zone (IFZ) in the active zone set consisting of the local device, the remote device, and the TR_Port. When the mapping is complete, QuickTools activates the new zone set.

The name of the inter-fabric zone begins with IFZ followed by the lowest device port WWN followed by the remaining port WWN, all uppercase, separated by underscores (_). For example, consider the following local and remote device WWNs:

• Local device: 21:00:00:e0:8b:0e:d3:59

• Remote device: 22:00:00:04:cf:a8:7f:2d The inter-fabric zone name would be:

IFZ_210000E08B0ED359_22000004CFA87F2D

4. Apply the same inter-fabric zone that was created on the local fabric to the active zoning on the remote

fabric. QuickTools creates a suggested list of commands during the mapping process that, when run on a remote fabric consisting of HP StorageWorks B-Series or C-Series switches, will make the necessary zoning changes to the remote fabric. See the HP StorageWorks 8/20q Fibre Channel Switch QuickTools Switch Management User Guide for important details on creating and using this list of suggested commands.When modifications to the active zoning on both fabrics are complete, the transparent routing connection becomes active, and the local devices will discover the remote devices.

Switch services

You can configure your switch to suit the demands of your environment by enabling or disabling a variety of switch services. Familiarize yourself with the following switch services and determine which ones you need.

• Telnet: Provides for the management of the switch over a Telnet connection. Disabling this service is not

recommended. The default is enabled.

• Secure Shell (SSH): Provides for secure remote connections to the switch using SSH. Your workstation

must also use an SSH client. The default is disabled.

• GUI Management: Provides for out-of-band management of the switch with Simple SAN Connection

Manager, QuickTools, SNMP, and SMI-S. If this service is disabled, the switch can only be managed inband or through the serial port. The default is enabled.

• Inband Management: Provides for the management of the switch over an inter-switch link using Simple

SAN Connection Manager, QuickTools, SNMP, or management server. If you disable inband management, you can no longer communicate with that switch by means other than an Ethernet or serial connection. The default is enabled.

• Secure Socket Layer (SSL): Provides for secure SSL connections for the QuickTools web applet and

SMI-S. This service must be enabled to authenticate users through a Remote Authentication Dial-in Service (RADIUS) server. To enable secure SSL connections, you must first synchronize the date and time on the switch and the workstation. Enabling SSL automatically creates a security certificate on the switch. The default is disabled.

NOTE: Simple SAN Connection Manager version 1.0 does not support the SSL service. If SSL is

enabled, you will be unable to manage the switch using this version of Simple SAN Connection Manager.

• QuickTools web applet (EmbeddedGUI): Provides for access to the QuickTools web applet. QuickTools

enables you to point at a switch with an internet browser and manage the switch through the browser. The default is enabled.

• Simple Network Management Protocol (SNMP): Provides for the management of the switch through

third-party applications that use the Simple Network Management Protocol (SNMP). Security consists of a read community string and a write community string that serve as passwords that control read and write access to the switch. These strings are set at the factory to these well-known defaults and should be changed if SNMP is to be enabled. Otherwise, you risk unwanted access to the switch. The switch supports SNMP versions 1, 2, and 3. The default configuration enables SNMP and disables SNMP version 3 security.

• Common Information Model (CIM): Provides for the management of the switch through third-party

applications that use the Storage Management Initiative–Specification (SMI-S). The default is enabled.

• File Transfer Protocol (FTP): Provides for transferring files rapidly between the workstation and the switch

using FTP. The default is enabled.

• Management Server (MS): Enables or disables the management of the switch through third-party

applications that use FC-GS-3 Management Server. The default is disabled.

• Call Home:

IMPORTANT: The Call Home service provides an e-mail notification capability for the switch. This

service has no relationship with the HP Call Home feature, which notifies only HP services.

Provides for automated e-mail notification of switch status and operating conditions based on specified event severity levels. The default is enabled. The Call Home service requires an Ethernet connection to at least one Simple Mail Transfer Protocol (SMTP) server. You must configure the Call Home service to do the following:

• Enable primary and secondary SMTP servers and specify their IP addresses

• Specify contact information Configure one or more Call Home profiles to specify e-mail recipients, message format, and the event

severity level that will initiate a message. In addition, you can configure periodic event data collection and processing through the Tech_Support_Center profile for automated status and trend analysis.
