1Introduction
This guide describes how to install and manage the 30-10022-01 loop switch.
Overview
The 30-10022-01 loop switch is a 12-port, speed agile switch. Enclosed in a 1U, half-rack form factor
enclosure, the switch is controlled by firmware loaded into the on-board flash mem ory. The switch is
designed as a central interconnect following the ANSI FC-AL standard. Devices are connected to the
switch through Small Form-factor Pluggable (SFP) transceivers and cables.
Each port independently supports 1 or 2 Gb/s of Fibre Channel bandwidth. Automatic port
configuration allows individual port access using automatic speed detection to connect devices based
on their supported speed. Smart synchronization validates proper initialization, checking signal
integrity and certain errors, such as OS and CRC, before allowing access to other Fibre Channel
devices. During normal operational when a change notification (LIP) is sent, the Bad Device
Recovery feature detects non-Fibre Channel compliant devices and removes them from participation.
Further validation continues to either bypass the port or allow access back into the Fibre Channel
network. Proper device notification is provided through the switch’s event log.
The switch also features automatic-configuration capability, which allows for IP address assignment
using DHCP- compatible networks. Once the switch is operational, complete switch configuration and
management is available through the intuitive, graphical-based Web Manager interface. In ad dition,
the switch features granular change notification management, retained system configuration
parameters, and a Command Line Interface (CLI).

Switch Installation
The switch can be installed in a rack or placed on a desktop.
Rack Installation
Guidelines for Mounting Equipment in a Rack
When installing equipment in a rack, give careful consideration to the following factors:
• The operating ambient temperature of rack-mounted equipment must not exceed the
maximum rated ambient temperature, which is indicated in this installation guide. (See
“Operating Conditions” on page 41.)
• The air flow clearances specified in this installation guide must be maintained within the rack.
(See “Operating Conditions” on page 41.)
• The AC supply circuit for rack-mounted equipment must be capable of supplying the total
current specified on all the labels of the rack-mounted equipment.
• All AC power supply connections must be properly earthed. To ensure the integrity of the
earth connection, special attention must be given to connections that are not directly
connected to the branch circuit (for example, power strips).
• The rack-mounting hardware has been carefully selected to properly support the equipment.
Any alternate rack-mounting hardware must provide equal or superior support.
• Plan the device installation starting from the bottom of the rack cabinet. Install the heaviest
device in the bottom of the rack cabinet.
For information on environmental requirements, see “Operating Conditions” on page 41.
Switch LEDs
The switch incorporates three sets of Light-Emitting Diodes (LEDs) to indicate Ethernet, switch, and
port status:
1. Ethernet LEDs – two separate LEDs indicating the network connection status.
2. System LEDs – three separate LEDs indicating the switch’s status.
3. Port LED – one multi-colored LED per port indicating the po rt’s status.

SFP Compatibility
SFPs are “hot-pluggable” into the switch, which allows host computers, servers, and storage devices
to be added dynamically without requiring power removal from the switch or any connected devices.
The switch supports Small Form-Factor Pluggable (SFP) modules that comply with the SFP
specification as produced by the MSA consortium and have passed qualification testing.
The following manufacturers offer 4Gb, 2Gb, and 1Gb optical, shortwave SFPs in both RoHS and
non- RoHS versions:
• Intel
• Finisar
• JDS Uniphase
• Agilent
9101112
Installing an SFP
Plugging an SFP into the switch will automatically send a change notification to indicate that the
device is ready to begin initialization.
CAUTION: Forcing an SFP into a port may damage the SFP and/or port.
To insert an SFP:
1. Remove dust covers or plugs from the SFPs, if provided .
2. Slide the SFP into the port, ensuring cor rect polarity, until the latch clicks into place.
Removing an SFP
To extract an SFP:
Determine what kind of extraction mechanism the SFP has and remove the SFP a s follows:
• If the SFP has a removal tag, remove the cable from the SFP and then pull the removal tag outward
and toward the side of the SFP with the tag.
30-10022-01 loop switch user guide 9
• If the SFP has a small plastic slider on the top or bottom, remove the cable from the SFP and then
push in the slider and hold while pulling out the SFP.
• If the SFP has a bale (small metal clasp), remove the cable from the SFP and then unlatch, pivot,
and pull the bale.
Attaching a Device to the Switch
To attach a device:
1. Make sure that the device is FC-AL compatible.
2. Attach a cable to the device.
3. Attach the other end of the cable to an SFP.
4. Make sure that the device and switch ar e operationa l and set to the same spe ed.
10 Switch Installation
Booting the Switch and Attached Devices
The following procedure is recommended when booting the switch and attached devices.
To boot the switch and attached devices:
1. Power on the storage device s.
2. Insert the plug end of the switch’s power cord to a properly g rounded p ower source.
3. Insert the power cord’s IEC connector end into the switch’s power receptacle.
The switch powers on and runs Power-On Self-Test (POST) diagnostics to verify the
fundamental integrity of the switch ports. All switch LEDs turn on (LEDs illuminate). Then,
excluding the Ethernet Link and Power LEDs, the LEDs turn off (LEDs extinguish). Once the
switch is operational, the LEDs display current status as described in “Switch LEDs” on
page 7.
NOTE: The power cord’s IEC connector plug serves as the switch’s disconnect device. To cycle
power to the switch, remove and reconnect the switch’s power cord.
4. Power on any other switches connected to the SAN.
5. For certain applications, switch configuration must be co mpleted befo re contin uing with the
next step. For information regarding switch configuration, see : Switch Management.
6. After all switches have initialized, power on the hosts or storage contro llers.
The network initializes.
NOTE: FC-AL compatible nodes must perform initialization procedures upon power-up in order to
function properly. It is the responsibility of the Fibre Channel driver software on FC-AL nodes to
perform this initialization.
7. Check all port LEDs.
The network should be fully operational at this point. However, it is appropriate to ensure that
proper discovery has taken place and all required devices are participating in the network.
Some host bus adapters may provide this level of functionality or it might be resident in the
application software on the host operating system.

3 Switch Management
The switch incorporates two distinct interfaces for managing and monitoring purposes:
• The Web Manager interface provides an intuitive graphical user interface that enables users to quickly
check switch status or modify switch settings in a visual environment.
• The Command Line Interface (CLI) provides flexibility and additional functionality for advanced users.
For a list of CLI commands, see : CLI Quick Reference on page 43. For additional information on the
CLI, see the HP EVA 4000/6000/8000 30-10022-01 loop switch CLI reference guide.
While these interfaces provide nearly identical functionality, this guide describes how to use the Web
Manager interface for switch configuration and monitoring, unless otherwise noted.
Getting Started
This section explains how to configure the switch’s Ethernet network settings prior to using the Web
Manager. Once the switch’s network settings are configured, you can use the Web Manager for
switch configuration and monitoring.
Configuring the Network Interface
Before using the Web Manager, ensure that the switch’s Ethernet network parameter settings are
correct for the network configuration. The switch ships with the following default IP settings:
• IP Address: 192.168.0.10
• Netmask: 255.255.255.0
• Gateway: 192.168.0.1
To adjust these settings to open the Web Manager, connect to the switch using the provided
null-modem serial cable and enter the new network settings.
To connect through a serial interface:
1. Attach one end of the included null-modem cable to the co mputer’s RS-232 serial port and
attach the other end to the switch’s RS-232 serial port.
2. Open a terminal session through a serial termin al emulation program (su ch as
HyperTerminal®) with the appropriate serial port (for example, COM1) and the following serial
port parameters:
• Bits per second: 115200
• Data bits: 8
•Parity: None
•Stop bits: 1
• Flow control: None
3. If using HyperTerminal, press E
If using the tip command on a UNIX workstation, do the following:
a. View the /etc/remote file and create an alias similar to Hardware but with the serial
port parameters above (suggested name: Switch).
b. Use the tip command to establish a connection through the created alias, for
example tip switch.
4. Type li and press E
5. Type the password at the prompt and press E
6. From the serial terminal emulation pr ogram, type config network ip and press ENTER.
The switch’s current IP parameters are displayed with a prompt for entering the IP address.
7. Change the IP address and p ress E
8. Use the mask and gateway comman ds to change th e subnet ma sk and defau lt gateway,
respectively.

9. Type save and press ENTER.
10. Type root reset and press E
11. Type y and press E
12. Attach the computer to the switch’s 10/100 Ethernet connector by doing one of the following:
• Attach an Ethernet RJ-45 cross-over cable directly between the computer and the switch.
• Attach two Ethernet RJ-45 twisted pair cables from the computer and the switch into an
operational Ethernet patch panel or hub.
DHCP IP Address Assignment
For Dynamic Host Configuration Protocol (DHCP)-enabled environments, you can enable the switch
to acquire an IP address from a DHCP server automatically. This feature is disabled by default.
To enable DHCP IP address assignment:
1. Use a serial terminal emulation program to connect to the switch as described in “Configuring
the Network Interface” on page 13.
2. Type the password at the prompt and press E
3. From the Root menu (root), type config network dhcp and press E
4. Enter 1 to enable DHCP and press E
NOTE: Once DHCP is enabled, the switch will automatically obtain an IP address from the DHCP
server. You will need to know this IP address in order to access the switch through the Web
Manager. You can locate the new IP address by attaching a serial cable and using a serial terminal
emulation program or contacting your network administrator.
