eatures
The Fibre Channel SAN Switch 8 has the following features:
Simplicity-- The Fibre Channel SAN Switch 8 is easy to set up and
s
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
s
devices and determines optimum data paths without intervention.
Flexibility-- The GBIC modules support single-mode and multi-mode
s
fiber transmission media. The switch's modular construction allows
flexibility in creating, upgrading, maintaining, and configuring a fabric.
Reliability-- Highly integrated, reliable, multifunction Application
s
Specific Integrated Circuit (ASIC) devices are used throughout the
switch.
High performance-- The low-latency, high-performance design
s
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
s
switch to perform sophisticated congestion management techniques
automatically.
Cascading-- Switches can be cascaded for large fabric support.
s
Switches can be interconnected for a large fabric with multiple fabric
connections.
Compatibility-- The Fibre Channel SAN Switch 8 is designed to
s
operate with other Compaq StorageWorks Fibre Channel Switches using
a compatibility mode.
Universal Ports-- Switch ports are designed to support F_, FL_, and
s
E_Port modes of operation. The software automatically selects the
optimum mode of operation.

Overview 1-5
able 1-2 describes the switch's technical features.
Table 1-2
Fibre Channel SAN Switch 8 Technical Features
Feature Description
Login (FC) 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 for each F/FL_Port can be up to 31 credits. For
buffer-to-buffer the E_Port, buffer-to-buffer credit can be a total of 31 credits
credit distributed among all 8 virtual channels.
In-order frame The switch delivers the frames to a destination F/FL_Port in the same
delivery order received by the source F/FL_Port. The in-order frame delivery is
maintained within a fabric of multiple interconnected switches.
Automatic Switch port address identifiers are selected using an automatic
address address assignment protocol. All ports within a fabric are assigned
assignment address identifiers. Each individual switch maintains its own address
pool for ports within the switch.
Hardware frame The switch implements hardware routing of frames between
routing 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 The switch allows the configuration of user-defined routes. Failed
routing 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 private devices.

Fibre Channel SAN Switch 8 Technical Features continued
Feature Description
Management The switch can be managed through the SNMP agent, Web
Management Tools, Telnetor 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, WorldWide 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 8 x 100 MB/s (0.8 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.
Switching Function
The Fibre Channel 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.
T
Overview 1-7
anageability
The Fibre Channel SAN Switch 8 can be managed in-band by using TCP/IP
embedded in the Fibre Channel protocol, or out-of-band by connecting to the
10/100Base-T Ethernet port. Management interfaces include SNMP, Web
Management Tools, or Telnet.
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 8 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 architectural limit switch
count in a fabric is reduced to 32, and the maximum number of multicast
groups is reduced to 31.
NOTE: To determine the type and number of switches currently supported in a SAN, go to
the Compaq Website at: http://www.compaq.com/products/storageworks/san/enterprise-
san.html.
If the compatibility mode is not set, the following error message displays when
you interconnect a Fibre Channel SAN Switch 8 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.

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.
P
Installing the Fibre Channel SAN Switch 8 2-3
ooling 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 airflow 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
s
Voltage capability of 100-240 VAC
s
Input voltage frequency of 47-63 Hz
s
Power capability of 100 W, maximum
s
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 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
package contents, on the bottom surface of the switch.

rack-mounting option kit for more information.
Installing GBIC Modules
GBIC-SW Module
The GBIC-SW module with the subscriber connector (SC) color-coded black
is based on short wavelength, 850-nm 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 8 must be ordered
separately. The Compaq part number for the short wave 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-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.
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 longwave
GBICs and "LW" for IBM shortwave GBICs.
R
Installing the Fibre Channel SAN Switch 8 2-5
he switch 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.
CAUTION: The GBIC module is keyed and can be inserted only one way. 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 modules into place by pressing the locking bar down. 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.
Fibre Channel Cable Specifications
All cables connect at the front of the switch. Recommended cabling supports
the switch's 1.0625 gigabits per second (Gb/s) transfer rate.
Fibre Channel Cables
Optical cables for the switch must be ordered separately. Cables of 1,641 ft
(500 m) or less should be multi-mode Fibre Channel cables. Cables that are
longer than 1,641 ft (500 m) should be single-mode. Multi-mode optical cables
are connected to the shortwave GBIC module in the switch. Single-mode
optical cables are connected to the longwave GBIC module in the switch.
Multi-mode cables should use 50/125 optical fibers, and 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 84,480 ft (10 km).

Making a Serial Connection
Use the serial connection on the Fibre Channel SAN Switch 8 to verify POST,
view and change the IP address of the switch, and reset the switch to factory
default values.
To make a serial connection, connect the serial cable that is provided in the kit,
part number 230436-B21 (this number replaces 188851-B21), to the Fibre
Channel SAN Switch 8 serial port, and to a COM port on a workstation.
NOTE: The serial port is only used for initial POST verification, initial IP address
configuration, and recovery of factory (default) settings.
F
Setting up the Fibre Channel SAN Switch 8 3-3
onnecting Through a Workstation
To execute initial switch operations through a workstation connected to the
serial port on the Fibre Channel SAN Switch 8:
1. On the workstation, launch a terminal emulation program.
NOTE: HyperTerminal is the remote communication program provided with Windows 95,
Windows 98, Windows 2000, Windows NT and can be found on the Accessories menu
that displays when you click Start, then 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. The following are settings for the serial port:
8-bit
s
No parity
s
One stop bit
s
9600 baud
s
No flow control
s
4. Press Enter to display the remote communication prompt.
Verifying the Power-On Self Test
The switch uses 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 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 restarts completely 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.
C
3-4 StorageWorks by Compaq Fibre Channel SAN Switch 8 Installation and Hardware Guide
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 IP address is used to establish a network connection to the switch
through the external Ethernet connection. The switch is configured with a
default IP address of 10.77.77.77. This IP address may not be compatible with
your configuration. The IP address can be changed by two different methods:
through the serial connection or through the network connection.
Through the Serial Connection
Use the front panel RS-232 serial port to change the IP address to a compatible
network address before connecting the switch to the network. When
connecting to the switch using this method, the switch's IP address is not used.
To set the IP address using the serial port:
1. Connect the serial cable (provided in the kit) between the switch's serial
port and a serial port connection on a host system.
2. Establish a connection between the host and the switch using a terminal
emulation program such as HyperTerminal.
3. When prompted, enter the user ID
admin
password: password
4. When POST completes, the following prompt confirms the connection:
switchName:userName>
Setting up the Fibre Channel SAN Switch 8 3-5
. At the prompt, enter the Telnet command ipAddrSet. You are prompted
for the following:
Ethernet IP Address [current address shown]: [enter new address if needed]
Ethernet Subnetmask [current]: [enter new subnet mask if needed]
Fibre Channel IP Address [current]: [enter new address if needed]
Fibre Channel Subnetmask [current]: [enter new subnet mask if needed]
Gateway Address [current]: [enter new address if needed]
6. After you enter the values, disconnect the serial cable and store it in a
secure location.
7. Access the switch through the network connection. You can manage the
switch using Web Management Tools or Telnet commands.
For detailed information on the ipAddrSet command and managing your
switch, see the Compaq StorageWorks Fibre Channel SAN Switch
Management Guide.
8. Write the IP address on the label on the front panel of 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.
Through the Ethernet Connection
The other method to change the IP address is to use the default IP address and
an Ethernet connection to the switch. Once the Ethernet is connected to the
switch, use the same ipAddrSet command to change the IP address.
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.
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 connection is
terminated when an Ethernet connection is made.
5
3-6 StorageWorks by Compaq Fibre Channel SAN Switch 8 Installation and Hardware Guide
hrough 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. See the
"Connecting Through a Workstation" section.
NOTE: For Windows 95, Windows 98, Windows 2000, and 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, and 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 using the passwd command.
Keyboard Issues
During a Telnet session from a Compaq Tru64 UNIX or OpenVMS machine,
the following keyboard issues occur:
The Backspace key produces a question mark character instead of
s
deleting characters. It is necessary to type Control + H to delete
characters.
The Delete key changes the case of the letter at the cursor and prevents
s
you from adding anything to the line.
The Left Arrow key deletes the character to its left and prevents you
s
from adding anything to the line.
