The Compaq StorageWorks Fibre Channel SAN Switch 8-EL is a low-cost,
high-performance, 8-port, gigabit Fibre Channel switch used to interconnect storage
devices, hosts, and servers in a Storage Area Network (SAN). The switch offers full
non-blocking performance for all eight ports, with each port capable of delivering 100
megabytes per second (MB/s) full duplex. Cut-through routing guarantees a maximum
latency of 2 microseconds from switch port to switch port.
Seven of the eight ports on the switch are fixed short-wave length optical media for
interconnecting devices at distances up to 500 m. One port is configured as a removable
GigaBit Interface Converter (GBIC) slot providing the flexibility to configure other
physical media such as long-wavelength optical.
12 Fibre Channel SAN Switch 8-EL Installation and Hardware Guide
The switch is designed as a 1U-high device. It may be installed in industry-standard EIA
racks or in a tabletop environment. Overall cost is reduced by using reliability
components, continuous monitoring of environmental components (fan status and
temperature), and a Single Field Replaceable Unit (FRU) design strategy.
The switch supports a Full Fabric capability. Full Fabric allows the Fibre Channel SAN
Switch 8-EL to be linked or cascaded to other StorageWorks Fibre Channel switches to
build a highly scalable SAN fabric. The Fibre Channel SAN Switch 8-EL supports F-port,
FL-port, and E-port connections and Distributed Name Server (DNS).
The base configuration supports one E-port connection. A field upgrade is available to
extend E-port connectivity to all ports.

Overview 13
Features
The Fibre Channel SAN Switch 8-EL has the following features:
Simplicity--The Fibre Channel SAN Switch 8-EL 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 8-EL 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.
Table 11 describes the switch's technical features.
Table 11: Fibre Channel SAN Switch 8-EL 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, frame buffers are available for each set of 4 Fibre
Channel ports.
14 Fibre Channel SAN Switch 8-EL Installation and Hardware Guide
Table 11: Fibre Channel SAN Switch 8-EL Technical Features (Continued)
Feature Description
Buffer-to-buffer credit for each F/FL_Port can be up to 31 credits. For the E_Port,
Adjustable
buffer-to-buffer credit can be a total of 31 credits distributed among all 8 virtual
buffer-to-buffer
channels.
credit
In order frame The switch delivers the frames to a destination F/FL_Port in the same order
delivery received by the source F/FL_Port. The in-order frame delivery is maintained
within a fabric of multiple interconnected switches.
Automatic address Switch port address identifiers are selected using an automatic address
assignment 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 The switch implements hardware routing of frames between communicating
routing 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 private devices.
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, 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.
Overview 15
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.
Switching Function
The Fibre Channel SAN Switch 8-EL 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.
Manageability
The Fibre Channel SAN Switch 8-EL can be managed in-band by using 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 1.6b or 1.6d), allowing both types of switches to
operate in the same fabric. To accomplish this compatibility, the Fibre Channel SAN
Switch 8-EL must be configured to use a specific addressing mode. This mode is
designated "VC-Encoded Address Mode."
NOTE: To determine the SAN compatibility, go to the Compaq Website at:
http://www.compaq.com/products/storageworks/san/enterprise-san.html.
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 31.

To gain access to the internal SNMP agent in the switch, and for remote Telnet and Web
access, connect to an existing Ethernet 10/100Base-T LAN through the front panel RJ-45
connector. This connection works for SNMP, Telnet, and Web access, and can be used for
remote monitoring and testing.

Installing a Single Fibre Channel SAN Switch 8-EL
To install a single Switch, perform the following steps:
1. Install a Fibre Channel adapter in each server, following the procedure outlined in your
adapter documentation.
2. Connect one Fibre Channel cable to each adapter.
3. Connect up to four Fibre Channel cables to the storage system.
4. Connect the free ends of the Fibre Channel cables from the storage system and servers
to the Fibre Channel ports on the switch's front panel.
5. Connect the power cord to the AC connector on the switch. The switch performs a
Power-On Self-Test (POST), which can take approximately 2.5 minutes.
6. If a malfunction occurs during POST, error messages are written to the switch error log
and can be viewed using a Telnet or terminal session when the POST session
completes.
7. If the malfunction prohibits the switch from completing the start process (fatal error),
the switch stops the start process. If the switch does not fully start, the switch prompt
will not be displayed when the serial port is connected.
NOTE: If a switch boot failure occurs, the switch must be taken offline for repair or
replacement. Contact your switch supplier for assistance.
8. The factory set IP address is: 10.77.77.77, and the class C Subnet Mask is:
255.255.255.0.
a. If the factory set IP address is compatible with your network, connect the Ethernet.
b. If the factory set IP address is not compatible with your network, follow the
procedures outlined in Chapter 3, "Setting up the Fibre Channel SAN Switch
8-EL," to make a serial connection through a workstation and to set the IP address.
9. Monitor the status indicators for port status. See the "Status Indicators" section in
Chapter 3, for descriptions of the indicators.
Installing Multiple Switches into an Existing SAN
To install multiple Switches, perform the following steps:
1. Connect the appropriate components as outlined in the "Installing a Single Fibre
Channel SAN Switch 8-EL" section.
210 Fibre Channel SAN Switch 8-EL Installation and Hardware Guide
2. Connect the serial cable, provided in the kit, between a host computer and the serial
port of the switch. See Chapter 3, "Setting up the Fibre Channel SAN Switch 8-EL," to
make a serial connection through a workstation and to set the IP address.
3. Connect the power cord to the AC connector on the switch. The switch performs
POST, which can take approximately 2.5 minutes.
4. If a malfunction occurs during POST, error messages are written to the switch error log
and can be viewed by a Telnet or terminal session when the POST session completes.
5. If the malfunction prohibits the switch from completing the start process (fatal error),
the switch stops the start process. If the switch does not fully start, the switch prompt
will not be displayed when the serial port is connected.
NOTE: If a switch boot failure occurs, the switch must be taken offline for repair or
replacement. Contact Compaq Technical Support for assistance.
6. Power down the new switch and connect the Fibre Channel cables from the SAN to the
new switch.
Cascading Switches
The switch supports cascading of up to seven hops.
NOTE: To determine the number of configurations currently supported in a SAN, go to the
Compaq Website at:
http://www.compaq.com/products/storageworks/san/enterprise-san.html.
The Domain ID number uniquely identifies a switch in a fabric. 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 were 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.
NOTE: Switch parameters for all switches in a SAN must be the same, or the switch may not
join the SAN.

Chapter
Setting up the Fibre Channel SAN Switch 8-EL
This chapter covers the following topics:
Making a Serial Connection
Saving and Restoring Switch Configuration Settings
Status Indicators
Making a Serial Connection
Use the serial connection on the Fibre Channel SAN Switch 8-EL to verify Power-On Self
Test (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 (which replaces 188851-B21), to the Fibre Channel SAN
Switch 8-EL 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.
Connecting Through a Workstation
To execute initial switch operations through a workstation connected to the serial port on
the Fibre Channel SAN Switch 8-EL:
1. On the workstation, launch a terminal emulation program.
NOTE: HyperTerminal is the remote communication program provided with Windows 95,
Windows 98, Windows 2000 or Windows NT, and can be found on the Accessories menu that
displays when you click Start, then Programs.
32 Fibre Channel SAN Switch 8-EL Installation and Hardware Guide
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.
The following are settings for the serial port:
8-bit
No parity
One stop bit
9600 baud
No flow control
3. Press the Enter key to display the remote communication prompt.
Setting the IP Address
To enable a connection to a Fibre Channel SAN Switch 8-EL, the switch must have a valid
IP address. You can set two IP addresses: one for the external
out-of-band Ethernet port, and one for in-band Fibre Channel network (IP) access.
A default Ethernet IP address of 10.77.77.77 and a default Fibre Channel network IP
address of 255.255.255.0 are preinstalled on the switch. Use the default address for the
external Ethernet connection to the network, then change the address with a Telnet
command.
You might need to set a compatible network address before you can connect the switch to
the network. In this case, set the address using the front panel RS-232 serial connection.
To set the IP address through the serial port:
1. After connecting to the switch through a workstation, enter the user ID:
admin
password: password
The following prompt confirms the connection:
switchName:userName>
Setting up the Fibre Channel SAN Switch 8-EL 33
2. 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]
3. After you enter the values, disconnect the serial cable and store it in a secure location.
4. Access the switch through the network connection. You can manage the switch using
Telnet commands or Web Management Tools.
5. For detailed information on the ipAddrSet command and managing your switch, see the
Compaq StorageWorks Fibre Channel SAN Switch Management Guide.
6. Write the IP address on the label on the front panel of the switch.
Resetting Factory Defaults
NOTE: See Appendix C, "Specifications," for a list of factory default settings.
If you change a password and forget it, the password can be reset to the factory default.
To revert to factory default values:
1. Power down the switch by unplugging the power cord.
2. Connect the serial cable from the host serial port to the switch serial port.
3. Power up the switch by plugging in the power cord.
4. Establish a connection between the host and the switch using a terminal emulation
program such as HyperTerminal.
5. From the host, log in to the switch.
6. When prompted, enter the user ID:
admin
password: password
7. Enter the Telnet command configDefault to reset usernames and passwords.
8. For more information on Telnet commands, refer to the Compaq StorageWorks Fibre
Channel SAN Switch Management Guide.
34 Fibre Channel SAN Switch 8-EL Installation and Hardware Guide
CAUTION: The configDefault command resets the password as well as many other
switch parameters. Be sure you understand the effects of this command before you
issue it.
NOTE: The configDefault command does not affect the SNMP agent configuration.
9. Close the terminal emulation program, disconnect the serial cable from the
workstation and the switch, and cover the serial port.
Saving and Restoring Switch Configuration
Settings
NOTE: See Appendix C, "Specifications," for a list of factory default settings.
Configuration settings can be lost upon switch failure. It is recommended that you save
your switch configuration settings using the configUpload Telnet command. 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 Microsoft Windows hosts.
On Windows NT, the FTP server may have to be installed from the distribution media and
enabled, or on Windows NT or Windows 9x there are several good freeware and shareware
FTP servers available.
support
The two utilities supplied for RSHD, RSHD.EXE and CAT.EXE, currently
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 of FTP or RSHD. If invoked with three parameters, RSHD is
used; otherwise, the presence of the fourth parameter (FTP password) selects FTP.
