Features

The Fibre Channel SAN Switch 16 has the following features:

■ Simplicity— The Fibre Channel SAN Switch 16 is easy to set up and

configure. After the Power On Self-Test (POST), add the switch’s Internet protocol (IP) address. The remainder of the setup is automated.

■ Intelligence— The operating system allows discovery of all connected

devices and determines optimum data paths without intervention.

■ Flexibility— The GBIC modules support single-mode and multi-mode

fiber transmission media. The switch’s modular construction allows flexibility in creating, upgrading, maintaining, and configuring a fabric.

■ Reliability— Highly integrated, reliable, multifunction Application

Specific Integrated Circuits (ASIC) devices are used throughout the switch.

■ High performance— The low-latency, high-performance design

requires no processor data path interaction. The Fibre Channel bandwidth is 100 megabytes per second (MB/s) per port (full duplex).

NOTE: The latency can differ when the device or destination is configured in a loop.

■ Automated congestion management— Virtual channels enable the

switch to perform sophisticated congestion management techniques automatically.

■ Cascading— Switches can be cascaded for large fabric support.

Switches can be interconnected for a large fabric with multiple fabric connections. .

■ Compatibility— The Fibre Channel SAN Switch 16 is designed to

operate with other Compaq StorageWorks Fibre Channel Switches using a compatibility mode.

■ Universal Ports— Switch ports are designed to support F_, FL_, and

E_Port modes of operation. The software automatically selects the optimum mode of operation.

1-4 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Table 1-2 describes the switch’s technical features.

Table 1-2

Fibre Channel SAN Switch 16 Technical Features

Feature Description

Data field size The Fibre Channel frame can be up to 2112 bytes in size. The number

of bytes must be a multiple of 4.

Buffering A total of 128 standard-size receive frame buffers are available for

each set of 4 Fibre Channel ports.

Adjustable buffer-to-buffer credit

Buffer-to-buffer credit for each F/FL_Port can be up to 31 credits. For the E_Port, buffer-to-buffer credit can be a total of 31 credits distributed among all 8 virtual channels.

In order frame delivery

The switch delivers the frames to a destination F/FL_Port in the same order received by the source F/FL_Port. The in-order frame delivery is maintained within a fabric of multiple interconnected switches.

Automatic address assignment

Switch port address identifiers are selected using an automatic address assignment protocol. All ports within a fabric are assigned address identifiers. Each individual switch maintains its own address pool for ports within the switch.

Hardware frame routing

The switch implements hardware routing of frames between communicating ports and supports self-routing of frames between the communicating ports. The path selection in a multiswitch configuration is based on a self-routing protocol.

User-defined routing

The switch allows the configuration of user defined routes. Failed paths are still used in the event of a failure.

Translative mode Translates 8-bit private loop addresses to 24-bit Phantom Public

Addresses to allow fabric-aware devices to access to private devices.

continued

Feature Description

Management The switch can be managed through the SNMP agent, Web

Management Tools, or Telnet included in the Compaq StorageWorks

Command Console software. These items are accessible from the

Internet Protocol over the RJ-45 10/100BaseT Ethernet port or any Fibre Channel port. You can use any SNMP-based management product to access the SNMP agent and any supported Web browser to use the Java Web Management Tools.

Name Server

The Name Server feature is based on the Simple Name Server model defined in the Fibre Channel Standard. This function allows external devices to discover other fabric-connected devices. Name Server manages a database that relates external device quantities, including mappings between N/NL_Port 24-bit Fibre Channel physical addresses, World Wide Names (WWN), IP addresses, FC-4 device types, and Initial Process Associators. External devices can register and query this information using the Name Server function, which is distributed across switches in a fabric.

Performance

A minimum aggregate routing capacity of 4,000,000 frames per second is

specified for Class 2, Class 3, and Class F frames. Non-blocking throughput of

up to 16 x 100 MB/s (1.6 gigabytes per second [GB/s]) is provided.

A maximum switch latency of less than two microseconds is specified for

Class 2, Class 3, and Class F frames when the output port is free.

Manageability

The Fibre Channel SAN Switch 16 can be managed in-band by using Fibre

Channel protocol, or out-of-band by connecting to the 10/100BaseT Ethernet

port. Management interfaces include SNMP, Web Management Tools, or

Telnet.

1-6 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Compatibility

The Fibre Channel SAN Switch software (version 2.0 and above) is compatible with the Fibre Channel Switch software (Version 1.6c or 1.6d), allowing both types of switches to operate in the same fabric. To accomplish this compatibility, the Fibre Channel SAN Switch 16 must be configured to use a specific addressing mode. This mode is designated “VC Encoded Address Mode.”

Invoke this mode using the

configure command, as described in Appendix A of

the Compaq StorageWorks

Fibre Channel SAN Switch Management Guide.

When using this compatibility mode, the maximum switch count in a fabric is reduced from 239 to 32, and the maximum number of multicast groups is reduced from 256 to 31.

If the compatibility mode is not set, the following error message displays when you interconnect a Fibre Channel SAN Switch 16 and a Fibre Channel Switch:

FABRIC, SEGMENTED, LOG_WARNING Description: Fabric segmented. Probable Cause: Incompatible fabric parameters/switches or conflict zones. Action: Reconfigure fabric or zones. See configure command.

Reliability

The following features ensure the switch’s reliability:

■ POST

■ BootROM Memory Testing

■ Temperature and fan-speed monitoring

■ Low component count

■ Optional dual-redundant hot-pluggable power supplies

Overview 1-7

Serviceability

The following features enhance the switch’s serviceability:

■ Simple enclosure

■ Loopback test modes for service

■ User-friendly diagnostics

■ No jumpers or switch settings

■ Error and significant event logging and reporting

■ Modular Field Replaceable Units

NOTE: For more information about field replaceable units (FRUs), see Chapter 7, “Repair and Replacement.”

NOTE: The Fibre Channel SAN Switch 16 can support a dual-redundant power supply configuration with hot-pluggable power supplies.

GBIC Modules

The Fibre Channel SAN Switch 16 accommodates up to sixteen GBIC modules. All interfaces have status lights on the front panel for quick, visual checks of the GBIC modules’ status and activity. If your installation requires less than 16 GBIC modules, a metal, spring-loaded door protects the unused port positions.

Shortwave (GBIC-SW) and longwave (GBIC-LW) GBIC modules are supported. Figure 1-3 shows a GBIC module.

Figure 1-3. GBIC module

Overview 1-9

GBIC-SW Module

The GBIC-SW module with the subscriber connector (SC) color-coded black

is based on short wavelength 850 mm lasers supporting 1.0625 GB/s link

speeds. The GBIC-SW module supports 50-micron multi-mode fiber optic

cables in lengths up to 500 meters. The GBIC-SW module uses a Class 1 laser,

which complies with the 21 CFR, subpart (J) standard as of the date of

manufacture. The GBIC-SW module is shipped with a protective plug that

should remain in place when no fiber optic cable is connected to the port.

GBIC modules for the Fibre Channel SAN Switch 16 must be ordered

separately. The Compaq part number for the shortwave optical GBIC module

for multi-mode cable is 380561-B21.

GBIC-LW Module

The GBIC-LW module with the SC color-coded blue is based on long

wavelength 1300 mm lasers supporting 1.0625 GB/s link speeds. The

GBIC-LW module supports 9-micron single-mode fiber optic cables in lengths

up to 10 kilometers. The GBIC-LW module is shipped with a protective plug

that should remain in place when no fiber optic cable is connected to the port.

Two single-mode GBIC modules and a short single-mode test cable can be

ordered in a kit (part number 340412-B21).

In the Switch Management Application page of the Web Management Tools,

the GBICs are identified differently depending on the type of GBIC and the

supplier. Some examples of the displays include “ID” for VIXEL shortwave

GBICs and “SW” for IBM shortwave GBICs.

Switching Function

The Fibre Channel SAN Switch 16 switching function is based on a central

memory bank and its associated data path control. Each switch port stores

received frames in the central memory, while passing a buffer pointer to the

forwarding port’s transmitter. The switch uses cut-through routing to route

frames from the receiving port to the transmitting port, providing the

transmitting port is free, without waiting for the end of the frame to be

received. This provides a low-latency data path within the switch. If the

transmitting port is busy, the frame can be temporarily stored in the switch’s

memory bank.

Selecting an Operating Location

The switch should be located in a secure or limited-access area to ensure that cable connections are not compromised. The operating location you select for the switch must meet the cooling air requirements and power requirements described in the following sections.

Cooling Requirements

Cooling air is drawn into the switch chassis by four fans mounted near the rear of the chassis. Exhausted air is expelled through vents in the front of the chassis. The combined air flow through the switch is 75 cubic feet per minute (cfm), with nominal bulk flow of 15 cfm.

CAUTION: Do not block the front or rear air vents. The switch uses ambient air for cooling.

Installing the Fibre Channel SAN Switch 16 2-3

Power Requirements

The AC power cord is connected to the switch connector on the right side of

the switch front panel. If you have dual-redundant power supplies, the second

AC cord is connected to the switch connector on the left side of the switch

front panel. Each AC power sources must meet these requirements:

■ A properly wired, earth-grounded AC outlet

■ Voltage capability of 85-265 VAC

■ Input voltage frequency of 47-63 Hz

■ Power capability of 150 watts, maximum

The switch has an auto-ranging power supply that automatically accepts

voltages within its range. There is no provision for surge protection built into

the switch power supply, so the AC source should include provisions to ensure

clean AC power.

Selecting a Switch Mounting Method

The switch can be placed on a flat surface, such as a tabletop, or mounted in an

optional, standard 19-inch equipment rack with an optional rack mounting kit,

part number 167365-B21.

Surface Mounting

To operate the switch on a surface, place the four rubber feet, provided in the

kit, on the bottom surface of the switch. Continue the installation procedure

with “Installing GBIC Modules,” later in this chapter.

Rack Mounting

You can install the switch in a RETMA 42U rack, in a Compaq rack, or in a

metric SW600 rack. Refer to the documentation that came in your

rack-mounting option kit for more information.

2-4 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Installing GBIC Modules

The switch can accommodate up to 16 GBIC modules. GBIC modules are

hot-pluggable. To install a GBIC module:

CAUTION: The GBIC modules contain static-sensitive components. Use electrostatic discharge (ESD) precautions while handling GBIC modules.

1. Insert a GBIC module into a Fibre Channel port. The module is keyed

and can only be inserted one way.

CAUTION: Do not force the GBIC module into a port if you feel resistance.

2. Fully insert the GBIC module until it is properly seated in the

Fibre Channel port. If you are using a GBIC module with a locking bar, lock the module in place with the locking bar. For other GBIC modules, the latch prongs automatically lock to prevent accidental removal of the GBIC module.

3. Insert a protective plug over the GBIC module’s fiber-optic connectors.

4. Repeat the procedure for each GBIC module to be installed.

Cable Specification

All cables connect at the front of the switch.

Fibre Channel Cables

Optical cables for the switch must be ordered separately. 500 meters or less cables should be multi-mode Fibre Channel cables. Cables that are longer than 500 meters should be single-mode. Multi-mode optical cables are connected to shortwave GBIC modules in the switch. Single-mode optical cables are connected to longwave GBIC modules in the switch. Multi-mode cables should use 50/125 optical fibers, SC Duplex connectors with a PC finish. Use of 62.5/125 should be restricted to situations where 62.5/125 optical fiber was previously installed and the link lengths are to be kept shorter than 200 meters. Single-mode cables typically use 9/125 optical fibers for distances up to 10 km.

Table 2-1 lists the cable specifications for Fibre Channel cables.

Connecting the Storage System and Host

The storage system and host devices connect to the GBIC modules in the switch’s Fibre Channel ports. Cable connectors are keyed and must be inserted properly into the GBIC module connectors. Remove the protective cover from the GBIC connector and make sure that the surfaces of all cable and GBIC module connectors are clean and free of dust and debris. Figure 2-2 shows the cable connections.

Figure 2-2. Connecting a cable to a GBIC module in a Fibre Channel port

Installing the Fibre Channel SAN Switch 16 2-7

Connecting the Power Cable

Connect the AC power cable to the AC connector on the front, right side of the

switch. If you have dual-redundant power supplies, connect the second power

cable to the AC connectors on the front, left side of the switch.

Figure 2-3. Connecting the power cable

2-8 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Connecting the Ethernet Cable

Connect the switch to an Ethernet 10/100BaseT network by plugging in the Ethernet cable at the RJ-45 connector. This connection allows access to the switch’s internal SNMP agent and remote Telnet and Web access.

Figure 2-4. Connecting the Ethernet cable

Cascading Switches

The switch supports cascading of switches. See the Compaq Solutions Kits for supported configurations involving cascading of switches.

The domain ID number uniquely identifies a switch in a fabric. Normally, the switch automatically assigns the domain ID when a switch is first powered on or when the switch disable/enable command is executed. When two switches are cascaded together, there might be an initial domain ID conflict if the switches had been assigned the same domain ID prior to being cascaded. This can be avoided by changing the domain ID with the configure command, by disabling and enabling one of the switches, or rebooting one of the switches. Refer to the Compaq StorageWorks Fibre Channel SAN Switch Management Guide for more information.

Front panel LED indicators

Verifying the POST

Setting the IP address

■ Initiating a Terminal or Telnet session

■ Save and restore switch configuration settings

Powering Up the Switch

Turn on the AC power switch located on each power supply. The switch

automatically runs the POST and the LED indicators become active.

3-2 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Front Panel LED Indicators

The color and flash speed of the front panel indicators shows the status of each Fibre Channel port. Table 3-1 contains descriptions of the port status indicators.

Table 3-1

Port Status Indicators

LED Indicators Definition

No light showing No light or signal carrier (no GBIC module or cable installed) for

media interface indicator.

Steady amber Receiving light or signal carrier, but not online yet.

Slow flashing amber Disabled, flashes every 2 seconds.

Fast flashing amber Error or fault with port, flashes every half second.

Steady green Online (connected to device over cable).

Slow flashing green Online but cannot make a proper fabric connection (loopback

cable is installed, fabric is segmented, or switch is connected to an incompatible switch), flashes every 2 seconds.

Fast flashing green Internal loopback (diagnostic), flashes every half second.

Flickering green The port is active and transferring data and frame traffic.

Alternating green and amber

The port is bypassed.

Verifying the Power On Self-Test

The switch employs POST to determine operating status and isolate problems. When a test completes successfully, the message “Passed” displays on the front panel display.

If the POST is completed successfully, the switch is ready to operate. Should the switch fail to complete POST successfully, the green power LED indicator on the front panel next to the RJ-45 Ethernet connector will flash. This indicates a fault in one of the initial stages of POST and signifies that the processor is unable to bring up the operating environment. If this error occurs, the switch could require repair.

If the switch’s operating system completely boots but other errors are encountered during POST, those errors are logged in the system error log. Use a Telnet session to view the error log.

Setting up the Fibre Channel SAN Switch 16 3-3

NOTE: Error messages are stored in RAM and are lost when the switch is rebooted or power is removed from the switch. View the error log messages before rebooting or removing power from the switch. You can view the error log by issuing either the errShow or errDump command. When all data-transferring processes external to the switch are complete, removing power from the switch does not disrupt the fabric.

Refer to the Compaq StorageWorks

Fibre Channel SAN Switch Management Guide for

more information on these Telnet commands.

Setting the IP Address

The switch is configured with default IP address 10.77.77.77. This IP address

is used to establish a network connection to the switch through the external

Ethernet connection. To set a compatible network address before connecting

the switch to the network, change the IP address through the front panel

controls.

To set the IP address using the front panel controls:

1. Select the Configuration menu using the right front panel button.

2. Scroll down to the Ethernet IP Address option. Select this option using

the right button.

3. Use the Up and Down buttons to change the IP address value. Use the

left front panel button to move to the next set of values.

4. When all values are set, press the right button to finish.

5. Confirm that the IP address is correct and select Yes to store the address

in flash memory.

NOTE: To be completely accessible on the network, the switch can require netmask and gateway addresses. See your network administrator to determine if additional addresses are necessary. These addresses can also be set through options on the Configuration menu.

3-4 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Initiating a Terminal or Telnet Session

A Telnet session is initiated through an Ethernet connection between a management station on the network and the switch Ethernet RJ-45 connector.

Through a Telnet session, you can manage the switch, perform diagnostics, and view error messages. To initiate a Telnet session:

1. Launch Telnet from a workstation connected to the network.

NOTE: For Windows 95/Windows 98/Windows 2000/Windows NT, select Run from the Start menu. Type Telnet, then click OK.

2. From Telnet, use the IP address to connect to the switch.

NOTE: For Windows 95/Windows 98/Windows 2000/Windows NT, select Remote System from the Connect menu on the Telnet window. Enter the IP address of the switch in the Host Name box.

3. Press Enter to display the login prompt. At the prompt, enter “admin.”

4. At the password prompt, enter “password.”

5. When the prompt switchName:userName> displays, enter a Telnet

command. You can change the password by using the passwd command.

During a Telnet session from a Tru64 UNIX or OpenVMS machine, the Backspace, Delete, and Left Arrow keys do not work properly. The keyboards shipped with these machines produce a “question mark” character instead of deleting characters when using the Backspace key. It is necessary to type Control + H to delete characters. The Delete key changes the case of the letter at the cursor and prevents you from adding anything to the line. The Left Arrow key deletes the character to its left and prevents you from adding anything to the line.

Enter the Telnet command “backSpace 1” to allow the Delete key to work on UNIX and OpenVMS machines.

For more information on the backSpace Telnet command and managing the switch remotely, refer to the Compaq StorageWorks Fibre Channel SAN Switch Management Guide that came with your switch.

Setting up the Fibre Channel SAN Switch 16 3-5

Save and Restore Switch Configuration Settings

Configuration settings can be lost upon switch failure. It is recommended that

you save your switch configuration settings using the configUpload Telnet

command. In order to restore your saved configuration settings, use the

configDownload Telnet command.

configUpload

This command saves the switch configuration to a host file. The upload

process uses either FTP (File Transfer Protocol) or the RSHD protocol (TCP

service 514). Both of these services are widely available on Unix hosts, but

less so on Windows hosts.

On Microsoft Windows NT, the FTP server may have to be installed from the

distribution media and enabled, or on Windows NT or Microsoft Windows 9x

there are several good freeware and shareware FTP servers available.

The two utilities supplied for RSHD, Rshd.exe and Cat.exe, currently do not

support uploads, only downloads. Therefore, in a Windows environment, FTP

must be used and the FTP server must be running before an upload can occur.

The command may be invoked without any parameters, in which case the user

is prompted for input, including choice or FTP or RSHD. If invoked with three

parameters RSHD is used, otherwise presence of the fourth parameter (FTP

password) selects FTP.

Figure 3-1 shows a generic example of the configUpload command.

switch:admin>configUpload Server Name or IP Address [host]: IP Address for Server: User Name [user]: File Name [config.txt]: Protocol (RSHD or FTP) [rshd]:

Figure 3-1. configUpload command example 1

3-6 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

If the upload fails, it is due to one of the following reasons:

■ The switch does not recognize the host name.

■ The host IP address can’t be contacted.

■ The user doesn’t have permission on the host.

■ The user runs a script that prints something at login.

■ The RSHD or FTP server is not running on the host.

The configuration file contains two types of lines, comments and name:value pairs. Comments are written with "[" as the first character of the line (when read back using configDownload, a line beginning with any punctuation character is treated as a comment).

Table 3-2

Syntax of a Name:Value Pair

Name Value Pair

line whitespace name whitespace ":" whitespace value

name component {"." component}

whitespace {" " | " "}

component {"a"-"z" | "A"-"Z" | "0"-"9" | "_" | "-"}

value {<any character not including "

NOTE: Elements enclosed in curly braces ({...}) indicate zero or more occurrences of the enclosed elements.

The configuration file is written as three sections. The first section contains the switch boot parameters (otherwise known as the switch’s identity). It has variables such as the switch’s name and IP address. This section corresponds to the first few lines of output of the configShow command.

The second section contains general switch configuration variables, such as diagnostic settings, fabric configuration settings, and SNMP settings. This section corresponds to the output of the configShow command (after the first few lines), although there are more lines uploaded than shown by the command.

The third section contains the zoning configuration. It corresponds to the output of the cfgShow command.

Parameters

■ host— A host name or IP address in quotes, for example "citadel" or

"192.168.1.48." The configuration file is uploaded to this host.

■ user— A user name in quotes, for example "jdoe." This user name is

used to gain access to the host.

■ file— A file name in quotes, for example "config.txt." Absolute path

names may be specified using forward slash "/". Relative path names create the file in the user's home directory on Unix hosts and in the directory where the FTP server is running on Windows hosts.

■ passwd— If present, selects FTP.

switch:admin>configUpload “citadel”,“jdoe”,“config.txt”,“passwd” upload complete

Figure 3-2. configUpload command example 2

configDownload

The download process uses either FTP (File Transfer Protocol) or the RSHD

protocol (TCP service 514) to download a previously saved configuration file

from a host system into the switch. Both of these services are widely available

on Unix hosts, but less so on Windows hosts. See the Telnet

configUpload

command for a description of the configuration file format.

On Windows NT, the FTP server may have to be installed from the

distribution media and enabled. There are several good freeware and

shareware FTP servers available for Windows NT, Windows 9x, and

Windows 2000.

To use RSHD on Windows NT, Windows 9x, or Windows 2000, two utilities

are supplied, Rshd.exe and Cat.exe. The FTP server or RSHD must be running

before a download can occur.

The command may be invoked without any parameters, in which case the user

is prompted for input, including choice or FTP or RSHD. If invoked with three

parameters RSHD is used, otherwise presence of the fourth parameter (FTP

password) selects FTP. Figure 3-3 shows a generic example of the

configDownload command.

3-8 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

switch:admin>configDownload Server Name or IP Address [host]: IP Address for Server: IP Address for Server: IP Address for Server: User Name [user]: File Name [config.txt]: Protocol (RSHD or FTP) [rshd]:

Figure 3-3. configDownload command example 1

If the download fails, it is due to one of the following reasons:

■ The switch does not recognize the host name.

■ The host IP address can’t be contacted.

■ The user doesn’t have permission on the host.

■ The user runs a script that prints something at login.

■ The file doesn’t exist on the host.

■ The file is not a switch configuration file.

■ The RSHD or FTP server is not running on the host.

■ The configuration data contains errors.

NOTE: The switch’s identity cannot be changed by configDownload. Parameters such as the switch’s name and IP address are ignored. They are the lines in the configuration file, which begin "boot."

NOTE: A licenseKey is only accepted if the boot.mac line matches the WorldWide Name of the switch performing the download, otherwise it is ignored.

The download process is additive, for example, the lines read from the file are added to the current switch configuration. It is therefore possible to change a single configuration variable by downloading a file with a single line. All other variables remain unchanged.

This is particularly important to understand when downloading a zoning configuration. Since the new zoning information is added to the current configuration there may not be any conflicts. If the current zoning configuration is to be replaced, then the key word "clear:" may be inserted into the configuration file immediately before the zoning lines.

Parameters

■ host— A host name or IP address in quotes, for example "citadel" or

"192.168.1.48." The configuration file is downloaded from this host.

■ user— A user name in quotes, for example "jdoe." This user name is

used to gain access to the host.

■ file— A file name in quotes, for example "config.txt." Absolute path

names may be specified using forward slash "/". Relative path names look for the file in the user's home directory on Unix hosts and in the directory where the FTP or RSHD server is running on Windows hosts.

If VC-Encoded Address Mode is in effect, the value can by any number between 0 and 31. Normally, the switch assigns itself a domain, but you can also assign this number manually.

Front Panel Switch Management 4-9

BB_credit

To view the buffer-to-buffer credit, press <Enter> while BB_credit displays on the front panel. The number that displays represents the number of buffers, from 1 to 16, available to the host.

R_A_TOV

To view the Resource Allocation Time Out Value, press <Enter> while

R_A_TOV displays on the front panel. You can adjust this value in 1-second

increments using front panel controls, but it displays in milliseconds.

NOTE: Use the flashSet command during a Telnet session to set the R_A_TOV value for values other than whole seconds.

R_A_TOV works with the Error Detect Time Out Value (E_D_TOV) to determine the switch’s actions when presented with an error condition. Allocated circuit resources with detected errors are not released until the time value has expired. If the condition is resolved prior to timing out, the internal time out clock resets. The R_A_TOV value can range from 1 to 120 seconds.

NOTE: The set value for R_A_TOV must be larger than the set value for E_D_TOV.

E_D_TOV

To view the Error Detect Time Out Value, press <Enter> while E_D_TOV displays on the front panel. You can adjust this value in 1-second increments using the front panel controls, but it displays in milliseconds.

NOTE: Use the flashSet command during a Telnet session to set the E_D_TOV value for values other than whole seconds.

The E_D_TOV flags a potential error condition when an expected response is not received (for example, an acknowledgment or reply in response to packet receipt) within the set time limit. If the time for an expected response exceeds the set value, an error condition results. The E_D_TOV value can range from 1 to 60 seconds.

NOTE: The set value for E_D_TOV must be smaller than the set value for the R_A_TOV.

4-10 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Data Field Size

To view the data field size, press <Enter> while Data Field Size displays on the front panel. You can adjust this value using the front panel controls. The data field size specifies the largest possible value, in bytes, for the size of a type 1 (data) frame. The switch advertises this value to other switches in the fabric during fabric construction and to new devices that connect to the fabric for the first time. Setting this to a value smaller than 2112 can result in decreased performance.

Non-SCSI Tachyon Mode

When set, multiple sequences from different sources are interleaved to Tachyon-based controllers at sequence boundaries rather than at frame boundaries, resulting in better performance from Tachyon-based controllers.

Disable Device Probing

When set, devices that do not register themselves with the Name Server will not be present in the Name Server database.

VC-Encoded Address Mode

When set, frame source and destination addresses use an address format compatible with some first-generation switches.

Per-Frame Route Priority

In addition to the eight virtual channels used in frame routing priority, support is also available for per-frame based prioritization when this value is set. When set, the virtual channel ID is used in conjunction with a frame header to form the final virtual channel ID.

Front Panel Switch Management 4-11

Virtual Channels

You can tune the switch for a specific application. The first two channels are not available because the switch reserves them for its internal functions.

NOTE: The default virtual channel settings are already optimized for switch performance. Changing the default values, if properly selected, can improve switch performance somewhat, but can also severely degrade switch performance. Do not change these settings without fully understanding the effects.

VC Priorities

To view the priorities assigned to each virtual channel, press <Enter> while VC

Priorities

displays on the front panel. The first two numbers are fixed, and display a 0 and a 1, respectively. The 0 in the first position indicates that this virtual channel, assigned to handle internal switch traffic, has the highest priority. The 1 in the second position shows the priority assigned by the virtual channel link control.

Positions three through eight can only be a 2 or 3,

indicating that the channel gives priority to Class 2 and Class 3 frame traffic.

Disable Fan Frames

Diagnostics

This chapters covers the following topics:

■ Overview of diagnostic tests

■ Diagnostic tests

■ Test menu

Overview

The Fibre Channel SAN Switch 16 is designed for maintenance-free operation. The switch’s self-diagnostic capabilities aid in isolating equipment or fabric failures. You can perform diagnostics when using the front panel controls or a Telnet session. Since the front panel displays a two-line limit, more detailed test results display through a Telnet session.

Isolating a System Fault

Various loopback paths are built into the switch hardware for diagnostic purposes. A loopback path test within the switch verifies the proper internal Fibre Channel port logic functions and the paths between interfaces and central memory. The switch diagnostics also support external loops, which include the motherboard and GBIC modules in cross-port configurations. These port-to-port diagnostics let you check for installed fiber cables and isolate port faults.

5-2 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Rebooting or Removing Power

Error messages are stored in RAM and are lost when the switch is rebooted or power is removed from the switch. Before rebooting or removing power from the switch, view the error log messages. You can view the error log by issuing either the errShow or errDump command. When all data-transferring processes external to the switch are complete, removing power from the switch does not disrupt the fabric.

Refer to the Compaq StorageWorks Fibre Channel SAN Switch Management Guide for more information on these Telnet commands.

POST

Table 5-1 lists the diagnostic tests automatically run during POST.

Chapter 6

Error Messages

This chapter explains the error message formats and possible errors associated with switch diagnostics. The following topics are included:

■ Switch error message formats

■ Diagnostic error message formats

■ Error message tables

Switch Error Message Formats

There are two error message formats depending on whether you are gathering information from the front panel or through a Telnet session. In all cases, the last error encountered is the first error displayed. Up to 64 messages are held in a buffer. If the 64-message limit is exceeded, the messages are overwritten in a first in, first out sequence.

Front Panel Format

When errors display on the front panel, the first line indicates the date and time the error occurred. The second line displays the module name (Diag), error name (REGERR_UNRST), and the severity level (1). The possible severity levels are:

■ 1—Critical

■ 2—Error

■ 3—Warning

6-2 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

■

4— Informational

■ 5— Debug

To display error messages using the front panel controls:

1. Select the Status menu from the front panel controls.

2. Select Error Log.

3. Scroll through the error log. If no errors are encountered, the front panel

displays “No Error.”

Telnet Format

During a Telnet session, use the errShow command to display all detected errors. The error counter goes to a maximum of 999. The following information displays for each detected error:

■ Number of errors detected

■ Task ID and task name (task names are displayed using the I command)

■ Error type, date and time, error level, and description

■ Number of occurrences (shown in brackets following the date and time

stamp)

The error message display pauses after each error and prompts you to press Enter to continue or Q to quit. Continue pressing Enter until the prompt => displays. Only diagnostic errors are assigned error numbers. If no errors encountered, the message “No Error” displays.

To display error messages through Telnet:

1. At the prompt, enter errShow.

2. Type <CR> to scroll through the error list.

Error Messages 6-3

Diagnostic Error Message Formats

If any port fails a diagnostic test, it is marked BAD in the display. To retest a port that has been marked BAD, clear the port and set the port to OK using the diagClearError (port #) Telnet command. This command clears the port status only and does not clear the logs or change the port’s condition. The diagClearError (port #) command should only be used during diagnostic procedures to reset a bad port for retesting. Some messages contain the following abbreviations:

■ sb = should be

■ er = bits in error

NOTE: If you run the portStatsShow or the diagShow command before you run a test, errors can display as a result of the normal synchronization process. These errors should be addressed if the number of errors found increases when running the portStatsShow command again.

Table 6-2 lists the action to take when a port fails a diagnostic test.

Chapter 7

Repair and Replacement

This chapter covers the recommended and supported field repair and replacement for the Fibre Channel SAN Switch 16. This chapter includes:

■ Switch configuration settings

Saving the settings

Restoring the settings

■ Field Replaceable Units

■ Replacing the power supply

■ Replacing a GBIC module

■ Replacing the fan assembly

■ Replacing the motherboard

■ Replacing the chassis

NOTE: Any switch repair or part replacement that is not explained in this chapter must be performed at a factory authorized repair facility.

7-2 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Switch Configuration Settings

Saving the Settings

When replacing a part that requires you to power down the switch, it is recommended that you save the switch configuration settings using the configUpload Telnet command. See the “Save and Restore Switch Configuration Settings” section in Chapter 3 for more detailed information.

Restoring the Settings

When you are ready to re-connect and power up the switch to an existing SAN:

■ If the switch is in a single switch configuration, restore the switch

configuration settings using the configDownload Telnet command. See the “Save and Restore Switch Configuration Settings” section in Chapter 3 for more detailed information.

■ If the switch is in a multiple switch configuration, clear the new switch

configuration settings with the cfgClear Telnet command (the new switch will acquire the configuration settings from the other switches in the SAN once the Fibre Channel cables are re-attached).

Refer to Appendix A of the Compaq StorageWorks Fibre Channel SAN Switch Management Guide for detailed information on these Telnet commands.

Replacing the Power Supply

There are no user-serviceable parts inside the power supply chassis. Opening the power supply voids its warranty and certification. The entire power supply unit can be removed according to the procedure outlined in the following section.

Removing the Power Supply

To remove the switch’s power supply:

1. Turn off the power to the power supply you are removing.

2. Remove the power cord attached to the power supply.

7-4 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

3. Pull down the metal handle on the top of the power supply unit.

Figure 7-1. Metal handle on the power supply

4. Gently pull out the unit.

NOTE: If you feel resistance when removing the power supply, pull the handle at an upward angle and slide the unit out.

Installing the Power Supply

To install a new power supply:

1. Slide the new power supply into its slot until the unit is flush with the

front panel.

2. Lock the metal handle into the power supply by pushing the handle up

and locking it into place.

3. Reattach the power cord to the power supply.

4. Turn on the power to the switch. The switch automatically runs POST

when power is applied to the switch.

NOTE: If you have a dual-redundant power supply configuration, the switch will only run POST if both power supplies are turned off and then turned on.

5. Check for error messages through Telnet.

Repair and Replacement 7-5

Replacing a GBIC Module

The GBIC modules are installed and removed by sliding them into and out of the slots on the front of the unit.

CAUTION: The GBIC modules contain static-sensitive components. Use electrostatic discharge (ESD) precautions while handling GBIC modules.

Removing a GBIC Module

If you are using a GBIC module with a locking bar, pull down the metal swing bar on the front of the GBIC and pull out the bar. Carefully wiggle the GBIC module from side to side to unseat it. Figure 7-2 shows a GBIC module with a locking bar.

Figure 7-2. GBIC module with a locking bar

7-6 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

If you are using any other type of GBIC module, squeeze the side prongs and carefully pull out the GBIC module. Figure 7-3 shows a squeeze-prong GBIC module.

Figure 7-3. Squeeze-prong GBIC module

Installing a GBIC Module

Insert the GBIC module into the appropriate port until its connector is firmly seated into the port. If you are using a GBIC module with a locking bar, lock the module in place with the locking bar. For other GBIC modules, the latch prongs automatically lock to prevent accidental removal of the GBIC module.

NOTE: The GBIC module is keyed so it can be inserted only one way. Do not force the insertion if the module does not slide in easily.

Replacing the Fan Assembly

To replace the fan assembly, remove the existing fan assembly, then install a new fan assembly.

NOTE: You need a #2 Phillips head screwdriver to remove and install the fan assembly.

NOTE: You do not need to power off the switch to replace the fan assembly. The switch

can safely run for up to 8 minutes under average conditions while the fan assembly is being replaced.

Repair and Replacement 7-7

Removing the Fan Assembly

To remove the fan assembly:

1. Unfasten the four captive screws on the rear of the switch.

2. Carefully pull the fan assembly out of the chassis rear panel.

Figure 7-4. Fan assembly

Installing the Fan Assembly

To install the fan assembly:

1. Slide the assembly into the back of the switch chassis.

NOTE: Make sure that the fan’s connector is oriented properly. Do not force the connector.

2. Fasten the four captive screws on the rear of the chassis.

7-8 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Replacing the Motherboard

To replace the motherboard, remove the existing motherboard assembly, then install the new motherboard assembly.

NOTE: You need a #4 flat head screwdriver to remove and install a motherboard.

Removing the Motherboard

CAUTION: The motherboard contains static-sensitive components. Use

electrostatic discharge (ESD) precautions when handling the motherboard.

1. Turn off all the power to the switch.

2. Remove all power cables and fiber optic cables attached to the front

panel.

3. Remove all GBIC modules. See “Removing a GBIC Module” earlier in

this chapter.

4. Remove the power supply or supplies. See “Removing the Power

Supply” earlier in this chapter.

5. Unscrew the captive screw on the front panel. You will notice the

assembly slowly moving forward as the screw loosens, exposing the copper connectors on the sides of the assembly.

Continue unscrewing the captive screw until there is no resistance.
