Introduction 1-3

Compaq StorageWorks SAN Switch 16
Features
The SAN Switch 16 has the following features:
■

Simplicity—The SAN Switch 16 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 circuits (ASICs) 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 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 SAN Switch 16 Installation and Hardware Guide

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

Table 1-2
Compaq StorageWorks SAN Switch 16 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
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

Introduction 1-5

Table 1-2
Compaq StorageWorks SAN Switch 16 Technical Features continued
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 16 x 100 MB/s (1.6 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 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 Telnet, SNMP, or Web Management Tools.

GBIC Modules
The SAN Switch 16 accommodates up to 16 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. 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) connector
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 SC connector color-coded blue is based on
long wavelength 1300 nm 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 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.

2-2 Compaq StorageWorks SAN Switch 16 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 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.

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. The AC power sources must each 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 155 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.

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.

Installation 2-3

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 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 16 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 an IBM GBIC module, 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.

Connecting the Storage Subsystem and Host
The storage subsystem 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

Setup

To set up the switch and prepare for switch management:
1. Power on the switch.
2. Verify the Power-On Self-Test (POST).
3. Set the IP address of the switch.
4. Initiate a Telnet session.

Powering up the Switch
Turn on the AC power switch located on each power supply. The switch
automatically runs the Power-On Self-Test (POST) and the LED indicators
become active.

Front Panel LED Indicators
The color and flash speed of the front panel LED indicators signify the status
of each Fibre Channel port. Table 3-1 summarizes the possible LED states.

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

Verifying the Power-On Self-Test
The switch uses the POST to determine 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 the 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.
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.

Setup 3-3

Setting the IP Address
The SAN Switch 16 has a default IP address. 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 (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 SAN Switch 16 Installation and Hardware Guide

Initiating a Telnet Session
A Telnet session is initiated through an Ethernet connection between the
network and the switch’s Ethernet RJ-45 connector.

domain number can be any value between 1 and 239. 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.

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

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.

Front Panel Switch Management 4-9

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.

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.

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

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.

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
This command specifies whether fabric address notification (FAN) frames are
sent to notify public loop devices of their node ID and address. To disable
FAN frames, press <Enter> while Disable Fan Frames displays on the front panel.
Set the value to 1 and FAN frames will not be sent. Set the value to 0 to enable
FAN frames.

Chapter

Diagnostics

This chapter discusses diagnostic testing using the front panel controls. See
Chapter 6, “Error Messages,” for information about the error messages
generated by diagnostic tests.

Diagnostic Overview
The Compaq StorageWorks 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 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.

5-2 Compaq StorageWorks SAN Switch 16 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 complete, removing power from the switch does not disrupt the
fabric.

displays on the front panel. This test ensures that:
■

The built-in self-repair (BISR) circuit in each ASIC chip does not report
failure to repair bad cells (bisr test).

■

The data cells can be uniquely written and read correctly
(data write/read test).

■

The data in any one ASIC can be read from any other ASIC
(asic-asic test).

■

5-6 Compaq StorageWorks SAN Switch 16 Installation and Hardware Guide

CAM Test
To verify that the SID translation required by QuickLoop and implemented
using content addressable memories (CAM) is functioning correctly, press
<Enter> while CAM Test displays on the front panel. Related error messages are
DIAG-CAMINIT, DIAG-CAMSID, and DIAG-XMIT.

Port Loopback Test
To test the switch circuitry up to the serial output of the ASIC, press <Enter>
while Port Loopback Test displays on the front panel. The Port Loopback test
verifies the intended functional operation of the switch by sending frames
from each port's transmitter back to the same port's receiver through an
internal hardware loopback. The Port Loopback test is an internal test that
continues to run until you press any button. Related error messages are
DIAG-INIT, DIAG-PORTDIED, DIAG-XMIT, DIAG-TIMEOUT,
DIAG-ERRSTAT, DIAG-STATS, DIAG-DATA, and DIAG-PORTABSENT.

Cross Port Test
To verify the intended functional operation of the switch, press <Enter> while
Cross Port Test displays on the front panel. Each port’s transmitter sends frames
by means of the GBIC module and external cable to another port’s receiver.
This test exercises the entire path of the switch.
You can connect any port to any other port in the same switch provided the
connection is of the same technology, for example, GBIC-SW ports to
GBIC-SW ports and GBIC-LW ports to GBIC-LW ports. Related error
messages are DIAG-INIT, DIAG-PORTDIED, DIAG-XMIT,
DIAG-TIMEOUT, DIAG-ERRSTAT, DIAG-STATS, DIAG-PORTWRONG,
DIAG-DATA, and DIAG-PORTABSENT.

Diagnostics 5-7

Spin Silk Test
To verify the intended functional operation of the switch, press <Enter> while
Spin Silk Test displays on the front panel. 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. Since
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.
NOTE: When running the Spin Silk test, set the operating mode value to 0 or 1.

Related error messages are DIAG-INIT, DIAG-PORTDIED, DIAG-XMIT,
DIAG-PORTSTOPPED, DIAG-ERRSTAT, DIAG-ERRSTATS, and
DIAG-PORTABSENT.

SRAM Data Retention Test
To verify that data written into the ASIC memories is retained, press <Enter>
while SRAM Data Retention Test displays on the front panel. Related error
messages are DIAG-REGERR, DIAG-REGERR_UNRST, and
DIAG-BUS_TIMEOUT.

CMEM Data Retention Test
To verify that the data written into the SRAMs that make up the central
memory is retained, press <Enter> while CMEM Data Retention Test displays on
the front panel. Related error messages are DIAG-LCMEM, DIAG-LCMRS,
and DIAG-LCMTO.

Display Test
To verify that the front panel display is functioning properly, press <Enter>
while Display Test displays on the front panel.

Display Test (long)

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 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 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.

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 16 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

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.

Optical Port Specifications
The Fibre Channel interfaces of a Compaq StorageWorks SAN Switch 16
system are equipped with optical port interfaces that use a shortwave
(780 to 850 nm) or long wavelength (1270 to 1350 nm) laser transmitter. The
laser complies with 21 CFR (J) Class 1 laser safety requirements. The
Fibre Channel interfaces use Non-Open Fibre Control Optical GBIC modules
in the switch circuit. Safe Class 1 operation is guaranteed by limiting optical
power emitted by the port, thereby eliminating the need for physical shutters.
The optical GBIC module uses the duplex-SC connector scheme.
