Overview of the Switch
Installation
Before the MSA Fabric Switch 6 can communicate with Compaq-managed devices,
all devices must be properly connected and powered on.
Ethernet RJ-45 Cable
This connector is provided for management through Simple Network Management
Protocol (SNMP). By default, the MSA Fabric Switch 6 is configured to use an IP
address of 127.0.0.1. To change this IP address, use ACU-XE, a terminal, or a
terminal emulator connected to the DB-9 serial port. Refer to Chapter 2, “Initial
Configuration of the Switch,” for more detailed information on this subject.
DB-9 Serial Cable
This connector is provided for advanced configuration and management.
The MSA Fabric Switch 6 is designed to function directly out of its shipping
container with no special configuration required. However, you have the ability to
configure and monitor various aspects of the MSA Fabric Switch 6 by using
ACU-XE or CIM-XE or by connecting a terminal or terminal emulator to the serial
port. See Chapter 2, “Initial Configuration of the Switch,” for more information on
using this interface.

Overview of the Switch
Hot-Pluggable
The MSA Fabric Switch 6 is hot-pluggable. The unit can be installed and replaced
without power-cycling the MSA1000.
When adding or replacing a switch, allow sufficient time to complete the power-on
self-tests (POST) and configuration tasks before using.
To power on the unit properly:
1. Power on the MSA1000.
On power up, the switch will run several POST tests and the GSI indicator will
display changing patterns (refer to the section “Reading the Global Service
Indicator” in Chapter 4, “Troubleshooting”).
2. Power on I/O device(s).
3. Verify that the storage device(s) are visible to the host(s).
4. Start Applications.
Before the MSA Fabric Switch 6 can communicate with Compaq-managed devices,
all devices must be properly configured, connected, and powered up. See Chapter 2,
“Initial Configuration of the Switch,” for installation instructions.

Initial Configuration of the Switch
This chapter details the procedures used to initially configure the MSA Fabric
Switch 6. Preliminary switch configuration includes entering the Ethernet and the
SNMP settings.
Two configuration methods are available:

Initial Configuration of the Switch
Configuration Overview
When a switch is initially connected to a network, the network does not recognize it
and does not know its IP address. Accessing the switch and entering the Ethernet and
SNMP settings assigns the switch a location and makes it available to the network.
After the switch is accessible, additional parameters must be entered. These
secondary configuration tasks can be performed from four different user interfaces,
including the text-based user interface (text-based UI), Command Line Interface
(CLI), the ACU-XE, and the Compaq MSA Fabric Switch 6 Management Utility.
The text-based UI can be used for the initial configuration tasks and the CLI can be
accessed from this interface to perform advanced configuration tasks.
The CLI of the switch provides access to extensive management and monitoring
functions and is available directly through the serial port in the front of the switch or
remotely through the switch’s Ethernet interface using telnet. During initial set-up, it
is accessed through the text-based UI. Subsequently, the system defaults to the CLI
or the text-based UI, depending on which interface was used last. For information on
the CLI, refer to Appendix C, “Command Line Interface.”
The ACU-XE is a web-based user interface primarily used to configure the array
controllers and hard drive arrays of the MSA1000. In addition, the ACU-XE can be
used to configure the switch. Instructions for configuring the switch using the
ACU-XE are included in this chapter. For information on using the ACU-XE to
configure the storage, refer to the StorageWorks by Compaq Modular SAN Array
1000 User Guide or the Compaq Array Configuration Utility XE User Guide.
The MSA Fabric Switch 6 Management Utility provides most of the functions
available in the text-based UI and the CLI, but in a user-friendly, web-based,
graphical interface. It is accessible from Compaq Insight Manager (CIM-XE) or any
workstations equipped with a web browser. For more information, refer to
www.compaq.com/storageworks.

Initial Configuration of the Switch
Using the Text-based UI to Configure the Switch
The text-based UI of the switch is available directly through the serial port in the
front of the switch. After the Ethernet settings are entered, the text-based UI can be
accessed remotely through the switch’s Ethernet interface using telnet. With the
following exceptions, all functions of the menu interface are available either directly
or through telnet.
•
The telnet interface is available only after the MSA Switch is completely booted.
This means the results of the initialization tests are not viewable and if a reset is
issued, the telnet connection is terminated.
•
Users are unable to change the password over the telnet interface.
Another difference between using the serial port interface and telnet is that when
using telnet, you can only get access to the switch after it has started up and has
initialized its network parameters. Consequently, you must have a directly-connected
terminal to initially configure network parameters and to view the power-up
information of the MSA Switch.
Connecting a Terminal to the Switch
NOTE: This process uses a computer running on Microsoft Windows NT 4.0 or later.
However, the switch can communicate with any operating system that utilizes a terminal
emulator. If your computer uses another operating system, be sure that the baud rate, data
bits, stop bits, parity, and terminal emulation are set for the selected serial port as specified in
this procedure.
To directly connect a terminal to the MSA Switch:
1. Make sure there is power to the switch and attach a terminal or terminal
emulator.
2. Connect a server serial port to the switch’s DB-9 serial port.
3. Power on the server (if it is not already on).
4. Access the terminal emulator on the server. In Windows NT 4.0, select
StartꢀProgramsꢀAccessoriesꢀHyperTerminal

5. Set up the properties for the terminal connection.
In Windows NT 4.0:
a. Double-click the Hypertrm icon.
b. Enter a name for the connection in the New Connection dialog box, select an
icon to represent the switch for future use, and click OK.
The Connect To dialog box is displayed.
6. From the Connect using drop-down menu, select the communications port
assigned to the serial port (for example, COM1, COM2) and click OK. In the
properties dialog box, enter the following port settings and select OK.

Initial Configuration of the Switch
Logging in to the Text-based UI
Upon connection to the switch or completion of the start-up sequence, you must log
into the MSA Switch to access the management functions. To do this, you must login
as “user” and enter the password assigned to the switch.
The default login variables assigned at the factory are:
Login: user
Password: ADMIN
To access the text-base UI:
1. At the Login prompt, enter user as the login variable.
>Login: user
2. At the password prompt, enter the assigned password.
>Password: ADMIN
Upon successful login, the main menu is displayed. Figure 2-1 is an illustration
of the initial Login menu.
Figure 2-1: Login menu
The main menu contains a brief summary of the status of the switch, including the
model number, the firmware version, and whether it passed its self-test.
NOTE: If the text-based UI from the previous connection was logged out while in the CLI, the
CLI prompt is displayed. To return to the text-menu interface from the CLI prompt, enter exit at
the prompt.
