Introduction 1-3

Compaq StorageWorks SAN Switch 8
Features
The SAN Switch 8 has the following features:
■

Simplicity—The SAN Switch 8 is easy to set up and configure. After
the Power-On Self-Test (POST), just 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 Circuit (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 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 SAN Switch 8 is designed to operate with other
Compaq StorageWorks Fibre Channel Switches using a compatibility
mode.

1-4 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

The following table describes the switch’s technical features.

Table 1-2
SAN Switch 8 Technical Features
Feature

Description

Explicit fabric login is supported.

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
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.

Feature

Description

Management

The switch can be managed through Telnet, the SNMP agent, or Web
Management Tools included in the 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, 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 8 x 100 MB/s (0.8 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 SAN Switch 8 can be managed in-band by using Fibre Channel protocol,
or out-of-band by connecting to the 10/100BaseT Ethernet port. Management

GBIC Modules
The SAN Switch 8 accommodates up to eight 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 eight
GBIC modules, a metal spring-loaded door protects the unused port positions.
Shortwave (GBIC-SW) and longwave (GBIC-LW) GBIC modules are
supported. The following figure shows a GBIC module.

Figure 1-3. Giga Bit Interface Converter (GBIC) module

GBIC-SW Module
The GBIC-SW module with the subscriber connector (SC) color-coded black
is based on short wavelength 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.

Introduction 1-9

GBIC-LW Module
The GBIC-LW module with the subscriber connector (SC) color-coded blue is
based on long wavelength 1300nm 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.

Switching Function
The SAN Switch 8 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.

2-2 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

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 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 the six fans mounted near the
rear of the chassis. Exhausted air is expelled through vents at 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.

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 source must meet these requirements:
■

A properly wired, earth-grounded AC outlet

■

Voltage capability of 100-240 VAC

■

Input voltage frequency of 47-63 Hz

■

Power capability of 100 watts, maximum

The switch has an autoranging 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.

Installation 2-3

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.

Surface Mounting
To operate the switch on a surface, you do not need to perform additional
steps. Continue the installation procedure with “Installing GBIC Modules,”
later in this chapter.

Rack Mounting
You can install the switch in a RETMA 41U or 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.

Installing GBIC Modules
The SAN Switch 8 can accommodate up to 8 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 IBM GBIC modules, lock the
modules into 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.

Making a Serial Connection
The switch is connected to a COM port of a workstation using a standard serial
cable. Through this connection, you can verify POST, view and change the
IP address of the switch, and reset the switch to factory default values.
NOTE: The serial port is only used for initial POST verification, initial IP address
configuration, and recovery of factory (default) settings.

Setup 3-3

Connecting Through a Workstation
To execute initial switch operations through a workstation connected to the
serial port of a switch:
1. On the workstation, launch a remote communication program.
NOTE: HyperTerminal is the remote communication program provided with Windows
95/98/NT and can be found on the Accessories menu that displays when you click Start
and select Programs.

2. Follow the prompts in the communication program. Be sure to connect
using the COM port you used to connect the workstation to the switch.
3. Change the port settings to communicate at 9600 bits per second.
4. Press Enter to display the remote communication prompt.

Verifying the Power-On Self-Test
The switch employs POST to determine its operating status and isolate
problems. When a test completes successfully, the message “Passed” displays
through the serial connection.
If 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 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.
NOTE: Error messages are stored in RAM and are lost when power is removed from the
switch. Access the error message log to view any error messages before removing power
from the switch.

Setting the IP Address
The switch’s IP address is used to establish a network connection to the switch
through the external Ethernet connection. To change the IP address to a
compatible network address before connecting the switch to the network, use
the front panel RS-232 serial port.

3-4 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

To set the IP address using the serial port:
1. Enter the ipAddrSet command at the prompt switchName:userName>.
2. Enter the Fibre Channel IP address and subnet mask, and the
Ethernet IP address, subnet mask, and gateway address when prompted.
3. For future reference, copy the new IP address to the label provided on
the top front edge of the switch.
4. Close the remote communication program and disconnect the serial
cable from the workstation and the switch.
NOTE: For dust and ESD protection, the switch includes a cover for the serial port.
Always cover the serial port when not in use.

Resetting Factory Defaults
If you change a password and forget it, the password can be reinitialized. To
reset factory defaults:
1. Establish remote communication from a workstation to the switch’s
serial port using a standard serial cable with a DB9 connector.
2. When the prompt switchName:userName> displays, enter the configDefault
command. The switch’s default values are restored.
CAUTION: The configDefault command resets the password as well as many
other switch parameters. Do not issue this command without understanding its
effects.

3. Close the remote communication program, disconnect the serial cable
from the workstation and the switch, and cover the serial port.

Initiating a Telnet Session
A Telnet session is initiated through an Ethernet connection between the
network and the switch’s Ethernet RJ-45 connector.
NOTE: The serial port connection and the Ethernet connection cannot be active at the
same time. The Ethernet connection takes priority, so the serial port is terminated when
an Ethernet connection is made.

Setup 3-5

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 95/98/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 95/98/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 using the passwd command.
For more information on managing the switch remotely, refer to the Compaq
StorageWorks SAN Switch Fabric Operating System Management Guide or
the Compaq StorageWorks SAN Switch QuickLoop Management Guide that
came with your switch.

Chapter

Diagnostics

This chapter discusses diagnostic testing using Telnet commands. See
Chapter 5, “Error Messages,” for information about the error messages
generated by diagnostic tests.

Diagnostic Overview
The Compaq StorageWorks SAN Switch 8 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 a Telnet session.

Isolating a System Fault
Various loopback paths are built in to 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.

4-2 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

Removing Power
Error messages are stored in RAM and are lost when power is removed from
the switch. Access the error message log to view any error messages before
removing power from the switch. When all data-transferring processes
external to the switch are complete, removing power from the switch does not
disrupt the fabric.

Power-On Self-Tests
The following table lists the diagnostic tests automatically run during the
Power-On Self-Test (POST).

4-10 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

crossPortTest Modes
The Cross Port test behaves differently according to the activated modes.

switchEnabled or switchDisabled mode
■

ONLINE mode (switch enabled before executing the test)—In the
ONLINE mode, only ports cable loopbacked to ports in the same switch
are tested. The test ignores ports connected outside of the switch. To be
successful, the test must find at least one port (if the singlePortAlso
mode is active) or two ports (if the singlePortAlso mode is not active)
cable loopbacked to each other. If not, the test displays the following
message:
Need at least 1 port(s) connected to run this test.
OR
Need at least 2 port(s) cross-connected to run this test.

■

OFFLINE mode (switch disabled before executing the test)—In the
OFFLINE mode, all ports cable loopbacked to similar ports in the same
switch are tested. The test aborts if one or more ports are not connected.
If any pair of ports is improperly connected (improperly seated GBIC
modules or cables, bad GBIC modules or cables, improper connection
of SW to LW, and so on), the following message displays:
One or more ports is not active, please doublecheck fibres on all ports.

singlePortAlso mode
Specify the singlePortAlso mode by executing the Cross Port test with a
second argument value of one.
sw:admin> crossPortTest 0, 1

In this mode, the Cross Port test allows a port to be cable loopbacked to itself
(port M is connected to port M) in addition to the supported cross connection
(port M is connected to port N). This configuration can be used to isolate bad
ports.

GBIC mode
Activate the GBIC mode by executing the following command before
executing the Cross Port test:
sw:admin> setGbicMode 1

Diagnostics 4-11

When activated, only ports with GBIC modules present are tested. The state of
the GBIC mode is activated until it is disabled as follows:
sw:admin> setGbicMode 0

An example mode of operation would be to disable the switch, set the GBIC
mode to 1, and execute the Cross Port test with singlePortAlso mode activated
to limit testing to:
■

Ports with GBIC modules installed

■

Ports properly cable loopbacked

■

Port connected to themselves (single port connections)

The command syntax is
crossPortTest <nFrames>, <0 or 1>

where <nFrames> determines the number of frames to run, and <0 or 1>
determines if a single port connection is allowed (0=not allowed, 1=allowed).
If you do not include the <nFrames> parameter, the test runs until you press
Enter.

spinSilk
Figure 4-10, Figure 4-11, and Figure 4-12 show the spinSilk command, which
verifies the intended functional operation of the switch. Each port’s transmitter
sends frames by means of the GBIC module and external cable, to another
port’s receiver at full hardware speed (1 GB/s). The entire path of the switch is
exercised. Because the processor does not compare data on each frame, the
Spin Silk test does not report the DIAG-DATA error. Other error messages
defined for the Cross Port test and the corresponding probable causes and
actions are applicable to the Spin Silk test.
The state of the GBIC mode affects the operation of the Spin Silk test. To
activate the GBIC mode, execute the following command prior to executing
the crossPortTest command:
switch:admin> setGbicMode 1

When activated, only ports with GBIC modules installed are included in the
Spin Silk test's list of ports to test. For example, if only ports 0 and 3 have
GBIC modules installed and the GBIC mode is activated, the Spin Silk test
limits testing to ports 0 and 3. The state of the GBIC mode is saved in flash
memory. The GBIC mode stays activated (even after reboots or power cycles)
until you disable it with the following command:
sw:admin> setGbicMode 0

4-12 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

An example mode of operation would be to disable the switch, set the GBIC
mode to 1, and execute the Spin Silk test to limit testing to:
■

Ports with GBIC modules installed

■

Ports that are properly cable loopbacked
IMPORTANT: This test cannot be executed on an operational switch. Before issuing the
spinSilk command, disable the switch using the switchDisable command.
NOTE: When running the Spin Silk test, you must set the operating mode value to 0 or 1.
Using operating mode 0 when running the Spin Silk test is recommended.

The command syntax is
spinSilk nMillions

where nMillions is the number of frames for the test to execute expressed in
millions of frames. If you do not include the nMillions parameter, the Spin Silk
test runs until you press Enter.

diagDisablePost
Figure 4-14 shows the diagDisablePost command, which disables POST
processing. The boot time without POST processing is approximately
50 to 55 seconds. A switch rebooted without POST generates the
DIAG-POST_SKIPPED error.
NOTE: Always execute POST processing to ensure the operational status of the switch
during the power up stage.
switch:admin> diagDisablePost
Committing configuration...done.
On next reboot, POST will be skipped.
Figure 4-14. diagDisablePost command example

diagEnablePost
Figure 4-15 shows the diagEnablePost command, which enables POST
processing. The boot time with POST processing is approximately
110 to 120 seconds for warm POST, and 165 to 175 seconds for cold POST.
POST processing is enabled by default.
switch:admin> diagEnablePost
Committing configuration...done.
On next reboot, POST will be executed.
Figure 4-15. diagEnablePost command example

diagShow
Figure 4-16 shows the diagShow command, which summarizes the diagnostics
results, including POST results, since the switch was last booted. The
following table describes the fields.
The diagShow command can be looped. For example, diagShow 4 executes
diagShow every four seconds until you stop it by pressing Enter. This command
can be used to isolate a bad GBIC module. A port with a changing LLI_errs
value is prefixed by ** in the display.

Diagnostic Error Messages
Error messages are stored in volatile RAM and are lost when you remove
power from the switch. Access the error message log to view error messages
before powering down the switch.
Error messages are displayed through a Telnet session. The messages are
stored in the system log and display when you execute the errShow command.
NOTE: If you run the portStatsShow command or the diagShow command before running
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.

Where multiple probable cause and corrective actions follow an error message,
they are listed with the most probable cause and action first and the least
probable cause and action last.
If a port fails a diagnostic test, it is marked BAD in the status display and is
ignored until the system is rebooted. To retest a port that has been marked BAD,
clear the port and set it to OK using the diagClearError (port #) command. This
command clears the port status, but does not clear the error logs or change the
port’s condition. Only use the diagClearError (port #) command during diagnostic
procedures to reset a bad port for retesting.
For more detailed error message information, see Chapter 5,
“Error Messages.”

Chapter

Error Messages

This chapter explains the error message formats and possible errors associated
with switch diagnostics. This section includes:
■

System error message formats

■

Diagnostic error message formats

■

Error message tables

System Error Message Formats
There is one error message format for the switch whether you are gathering
information from the local RS-232 serial port or using a remote 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.
The errShow command displays 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)

5-2 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

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.

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#) 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.

Federal Communications Commission
Notice
Part 15 of the Federal Communications Commission (FCC) Rules and
Regulations has established Radio Frequency (RF) emission limits to provide
an interference-free radio frequency spectrum. Many electronic devices,
including computers, generate RF energy incidental to their intended function
and are, therefore, covered by these rules. These rules place computers and
related peripheral devices into two classes, A and B, depending upon their
intended installation. Class A devices are those that may reasonably be
expected to be installed in a business or commercial environment.
Class B devices are those that may reasonably be expected to be installed in a
residential environment (that is, personal computers).

A-2 Compaq StorageWorks SAN Switch 8 Installation and Hardware Guide

The FCC requires devices in both classes to bear a label indicating the
interference potential of the device as well as additional operating instructions
for the user.
The rating label on the device shows which class (A or B) the equipment falls
into. Class B devices have an FCC logo or FCC ID on the label.
Class A devices do not have an FCC ID on the label. Once the class of the

Appendix

Electrostatic Discharge

To prevent damage to the system, heed the precautions you need to follow
when setting up the system or handling parts. A discharge of static electricity
from a finger or other conductor can damage system boards or other staticsensitive devices. This type of damage can reduce the life expectancy of the
device.
To prevent electrostatic damage, observe the following precautions:
■

Avoid hand contact by transporting and storing products in static-safe
containers.

■

Keep electrostatic-sensitive parts in their containers until they arrive at
static-free workstations.

■

Place parts on a grounded surface before removing them from their
containers.

■

Avoid touching pins, leads, or circuitry.

■

Always be properly grounded when touching a static-sensitive
component or assembly.

Grounding Methods
There are several methods for grounding. Use one or more of the following
methods when handling or installing electrostatic-sensitive parts:
■

Use a wrist strap connected by a ground cord to a grounded workstation
or computer chassis. Wrist straps are flexible straps with a minimum of
1 megohm ± 10 percent resistance in the ground cords. To provide
proper ground, wear the strap snug against the skin.

■

Use heel straps, toe straps, or boot straps at standing workstations. Wear
the straps on both feet when standing on conductive floors or dissipating
floor mats.

■

Use conductive field service tools.

■

Use a portable field service kit with a folding static-dissipating work
mat.

If you do not have any of the suggested equipment for proper grounding, have
a Compaq authorized reseller install the part.
NOTE: For more information on static electricity, or for assistance with product
installation, contact your Compaq authorized reseller.
