1 ATTO iPBridge provides storage options

The ATTO iPBridge

2600 iSCSI to SCSI bridge offers an affordable opportunity to transform SCSI

storage into network-enabled addressable devices, creating scalable solutions for an iSCSI SAN.

The iSCSI protocol allows storage devices such as hard drives, tape drives and libraries and CD jukeboxes to attach easily to Internet Protocol networks such as Gigabit Ethernet. The ATTO iPBridge supports the high throughput needs of streaming data transfers, optimizing performance and management using ATTO Technology intelligent Bridging Architecture™. Gigabit Ethernet (GbE) is a transmission technology based on the Ethernet format and protocol used in local area networks (LANs), providing a data rate of 1 billion bits per second (one gigabit) as defined in the IEEE 802.3 standard. The iSCSI protocol increases the capabilities and performance of storage data transmission by transmitting data over local area networks (LANs), wide area networks (WANs), or the Internet, providing location-independent data storage and retrieval to enhance current and future Storage Area Networks (SANs). The iSCSI protocol enables complete SAN solutions based on a Gigabit Ethernet network infrastructure. iSCSI is a logical SAN alternative to direct-attached storage where simplicity, flexibility and price/performance are critical. Data may be accessed from virtually anywhere that can be reached through the Internet, eliminating physical boundaries.

Embedded software features

• SpeedWriteTM:a performance-enhancing capability that significantly boosts Write performance by efficiently managing Write commands between host and a tape device.

• Security through Virtual LANs, Access Control Lists (ACLs) and multiple levels of password protection

• Advanced Diagnostics include software eventlogging capability time and date stamped by the real time clock. You can also determine numerous status and current configuration parameters.

• Management and monitoring through ATTO ExpressNAV, a web-based management application that allows all of the configurable settings for the iPBridge to be defined, viewed and edited; E-mail notification of errors and Simple Network Management Protocol (SNMP) support.

Connectivity, infrastructure solutions

The topology of a heterogeneous Storage Area Network shown on the next page demonstrates the critical role ATTO products play in the design and implementation of a SAN. Whether your application needs are data-intensive or bandwidth intensive, you need to store and manage that data and then deliver it to end-users efficiently. ATTO products have been engineered with the highest performance and lowest cost available today.

iSCSI also lowers the investment cost of adding new servers to a SAN for both primary storage and backup applications.

2.1 Target management

Storage devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use the Automatic Target Management feature in the ATTO ExpressNAV interface.

CAUTIONCAUTION

Changing the device map can affect the host’s view of devices and your application configuration.

To map devices, you must connect the devices to one of the iPBridge SCSI ports. To access mapped devices over Ethernet, you must have a host computer connected to one of the iPBridge Ethernet data ports.

You have two options to map devices:

1 The default is set up as a single target node in

which a host or initiator views the iPBridge as a single iSCSI node with all available devices shown as LUNs on a single iSCSI target.

2 You may set up multiple target nodes which

allow greater flexibility to grant or deny access between initiators and devices as needed.

Default target node

The default target is set as a single target with Access Control (ACL) disabled and CHAP authentication disabled. The default target node cannot be deleted. The iPBridge maps devices automatically although you can map devices yourself.

Automatically configure a single target

1 If you are not already in the ExpressNAV GUI,

type the IP address of your iPBridge, as found in Discover the IP address standard browser and press Enter.

2 From the ExpressNAV main menu, click on the

Auto Target Mgt menu item on the left side of the screen.

3 Click on the Map all devices to default target

button.

4 When the action is complete, the iSCSI Target

Management page appears. Make any adjustments to the mapping or begin a discovery session.

on page 5, in a

If you divide the default single target node into multiple target nodes, you must set up access to each node separately.

See Exhibit 2.1-1 on page 9 to see the difference between single target node and multiple target nodes.

Targe t na mes

Each iSCSI target node accessed through the Ethernet port on an iPBridge is identified by a unique world-wide iSCSI-qualified name. This format references the iPBridge serial number and target node name:

iqn.1995-12.com.attotech:ipbridge: serialnumber <targetname>

If you are prompted to restart the iPBridge, go to the Firmware Restart page and restart the iPBridge.

Manually configure a single target node

1 If you are not already in the ExpressNAV GUI,

type the IP address of your iPBridge, as found in Discover the IP address standard browser and press Enter.

2 From the ExpressNAV main menu, click on the

Manual Target Mgmt menu item on the left side of the screen.

3 Click on the Device Maps link of the default

target.

4 Select the devices from the box on the right

hand side of the screen and drag to the appropriate LUN on the left.

5 Click Submit.

If you are prompted to restart the iPBridge, go to the Firmware Restart page and restart the iPBridge.

on page 5, in a

ATTO Technology Inc. iPBridge Installation and Operation Manual

Page 17

Multiple target nodes

Multiple targets allow you to create a more configurable mapping scheme which can segregate storage into different iSCSI nodes within the iPBridge, with each iSCSI target having its own set of access criteria.

For example, if you have two servers and a library with four tapes and a media changer, the default nodes would provide both servers access to all tapes and the media changer (default target mode).

If you configure multiple target nodes, you are able to map some devices to one server and other devices to the other server, requiring separate user names and passwords for access using various methods including Access Control Lists, iSNS and CHAP authentication. Consult with your network administrator and refer to Exhibit 2.1-1,

iSCSI commands

on page 51 and the

Glossary

on page v of the Appendix.

Note

If you map actual storage to more than one iSCSI target and a server has authorization for both targets, the server could show duplicate storage without any warning.

Automatically configure multiple targets

1 If you are not already in the ExpressNAV GUI,

type the IP address of your iPBridge, as found in Discover the IP address standard browser and press Enter.

2 From the ExpressNAV main menu, click on the

Automatic Target Management menu item on the left side of the screen.

on page 5, in a

3 Click on the Map each device to its own

target button. See Exhibit 2.1-2 on page 10. The iPBridge maps itself as a device at LUN 0. A target name suffix is added to the iqn of each device such as

vendorid-devicename-xxx

• vendorid is the device vendor ID

• devicename is the device’s inquiry device name.

• xxx is a device index

When the action is complete, the screen returns to the iSCSI Target Management page. If you are prompted to restart the iPBridge, go to the Firmware Restart page and restart the iPBridge.

E-mail notification

E-mail notification using SMTP (Simple Mail Transfer Protocol) allows the iPBridge to send an E-mail message to you, a network administrator or other users when certain events occur:

• critical and warning temperature conditions

• critical and warning voltage conditions

• power is on

The severity level can be or

none

• All means warnings, critical events and

informational messages are sent.

• Critical means only critical event notifications

are sent.

• Warning means only warnings and critical event

notifications are sent.

• None means no notification is sent.

When an event occurs that warrants E-mail notification, the iPBridge scans each of its ports until the E-mail is sent successfully. Each attempt takes one minute. The E-mail function only sends messages; it cannot respond to a rejection by a server for an invalid address.

Each E-mail is time stamped when it leaves as part of the SMTP header information.

Component check

Use this procedure to check system components. For more information on the commands used in this procedure, refer to

interface

on page 31.

Checking SCSI devices

1 Check SCSI devices to make sure they are all

set to different SCSI IDs.

By default, the iPBridge SCSI ports use SCSI ID 7 so drives should use IDs 0 through 6 and 8 through 15.

2 Check the SCSI device power. Make sure the

devices are powering up.

3 Watch the drive lights before, during, and after

startup. Many drives have term power lights that should be on before startup and turn off when system boots.

4 Verify the external terminator is the correct type

and does not have damaged pins.

5 Check cable integrity. Check the cables for

solid connections. Make sure they are screwed down. Inspect cable ends for bent pins.

6 If termination is correct, and the problem

persists, try drives one at a time with different cables, adding drives and cables until the problem occurs. This helps pinpoint the drive or cable causing the problem.

7 Check with the manufacturer of SCSI device(s)

for further troubleshooting methods.

If SCSI devices appear to be working, move on to the iPBridge SCSI port section.

Checking the iPBridge SCSI ports

1 Verify the iPBridge has its termination set

properly. By default, termination is

2 Click on the Status page and view the

information on the product version.

3 If an update is needed, download the update

from www.attotech.com.

Refer to Updating firmware

If no devices appear, re-check SCSI cables and termination. If garbage information appears, the problem is most likely a bad SCSI cable or termination.

3 Check the internal cabling of the SCSI device.

LVD SCSI cable lengths are limited to 12.5 meters. Longer cable lengths can cause problems. Internal cabling is also considered when calculating total cable length. For details, refer to Cabling

4 Some older SCSI devices improperly negotiate

with the iPBridge SCSI port. If older devices are not showing up, contact your service representative.

5 If all devices appear, invoke the ScsiTargets

command several times on each SCSI port to verify that the devices can be seen. If devices disappear then appear again, the problem is most likely a SCSI cable. For information on the ScsiTargets command, refer to SCSI

configuration commands on page 49.

If all devices appear and remain, move to the iPBridge internal configuration section.

When changing any setting on the iPBridge the configuration must be saved by using either the saveConfiguration CLI command or through the ATTO ExpressNAV interface.

Checking the serial port

1 Verify you have the correct settings and that

your terminal is configured to:

• Baud rate: 115200

• Data bits: 8

• Stop bits: 1

• Parity: off

• Flow control: None

2 Verify that your serial cable is less then two

meters in length.

Troubleshooting

Page 30

Checking the iPBridge internal configuration

Verify that the SCSI devices are mapped properly. Check in the ATTO ExpressNAV interface or use the

routedisplay iSCSI command to show mappings. If

devices do not appear, power down the iPBridge and power back on. Refer to page 13,

Mapping devices: iSCSI

Mapping commands

on page 15 and

on page 57.

When changing any setting on the iPBridge, the configuration must be saved by using either the

saveConfiguration

CLI command or through the

Restart

page.

Checking iPBridge Ethernet ports

1 Check Ethernet cable integrity. Check the

cables for solid connections. Cat5 cable can cause connection issues with Gigabit Ethernet. Cat6 cable is the best cabling for the iPBridge.

2 Verify the IP address, subnet mask, and

gateway are properly set on each data port on the iPBridge for your network environment. Refer to Getting an IP address

3 Verify that the Ethernet speed is set to auto:

invoke the get EthernetSpeed all command, check the Ethernet page of the ATTO ExpressNAV interface, or check the LED link lights to determine if the Ethernet speed is correct.

4 Determine if the iPBridge is set to get its IP

information from a DHCP server. If so, verify that the DHCP server has available IP addresses. Refer to Getting an IP address page 10.

5 Verify that each used Ethernet port on the

iPBridge can be pinged from the desired host. Refer to Ping

If the host cannot ping the iPBridge ports and the iPBridge ports are properly configured, continue to the Local Area Network/Wide Area Network section, Checking the LAN/WAN page 21.

Verify that each port on the iPBridge can ping each desired host. Refer to Ping the iPBridge cannot ping the host, continue to

switch/host at the desired speed. You may have to force the host/switch or the iPBridge to the desired speed.

8 Verify that the host is logging into the iPBridge

correctly by viewing the Connections page and determining if there a “session open” status.

9 Verify that you are using the correct log in

procedure for your initiator. For example: When connecting using the Adaptec initiator, the log on screen requests the iPBridge iqn (iSCSI qualified name). If left blank, Adaptec cannot log in. Enter “iSCSI” into this field for auto iqn discovery.

When changing any setting on the iPBridge the configuration must be saved by using either the

saveConfiguration

CLI command or through the

ATTO ExpressNAV interface.

Checking the LAN/WAN

1 Verify that the switch/switches are segmented

properly so that hosts and the iPBridge have access to each other.

2 If there are routers involved in the setup, make

sure the IP addresses and/or MAC addresses of the iPBridge are allowed through the router.

3 Verify that the switch can see the iPBridge on

the port(s) in question. Refer to your switch vendor’s guide for more information.

Checking the iSCSI Host Adapter or NIC

iSCSI host adapters appear as a type of Storage Controller to the host OS, not as a standard NIC. These adapters usually have hardware acceleration to offload the TCP processing from the host. Configuration of these adapters is usually done through the vendor’s own utility and not through the OS itself.

NICs come in two types: accelerated and unaccelerated. Accelerated NICs use some hardware to offload some of the TCP processing from the host. Unaccelerated NICs make the OS do all TCP processing.

To check the iSCSI host adapter or NIC

1 Check cable integrity. Check the cables for

solid connections. Make sure they are plugged in properly. Inspect cable ends for broken clips and improper wiring.

2 Verify that the iSCSI host adapter or NIC is

configured with the correct IP information.

3 If using DHCP, verify that the DHCP server is

assigning the correct IP information to the host.

ATTO Technology Inc. iPBridge Installation and Operation Manual

Page 31

4 Verify that the hosts are running the

recommended driver and firmware level for the iSCSI host adapter or NIC vendor.

5 Verify that the hosts and the iPBridge are using

the same port number to communicate via iSCSI. The default port number for the iPBridge is 3260. Refer to iSCSIPortNumber

6 Make sure the host adapter/NIC is configured

to log into the iPBridge. Some iSCSI host adapters do not re-login upon reboot or unplug/replug event without marking a check box.

7 Some older switches cannot autonegotiate

between the host and the switch properly. You may have to force the host or switch to the desired speed.

on page 55.

For a NIC using an OS iSCSI driver, continue to the iSCSI OS driver section.

Checking the iSCSI OS driver

This section is for hosts using a driver that allows the OS to talk to iSCSI targets via a NIC, not an iSCSI storage adapter.

1 A PC using an iSCSI storage adapter and an

iSCSI OS driver might not work correctly on the same machine. Check with the vendors to make sure they are compatible.

2 Verify that the PC has the latest iSCSI driver as

well as the required service packs and patches. Check with the iSCSI OS driver vendor for more information.

3 Verify that the iSCSI OS driver has started.

Look under Device Manager for Windows or lsmod for Linux.

4 Verify that the iSCSI OS is still looking for the

iPBridge at the right IP address.

5 If using DHCP, verify that the DHCP server is

assigning the correct IP information to the host. Refer to Ethernet Port Configuration

23.

6 Verify that the NIC is configured with the correct

IP information.

7 Verify that the hosts and the iPBridge are using

the same port number to communicate via iSCSI. The default port number for the iPBridge is 3260. Refer to iSCSIPortNumber

8 Check cable integrity. Check the cables for

solid connections. Make sure they are plugged in properly. Inspect cable ends for broken clips and improper wiring.

on page

on page 55.

Checking the Operating System

1 Verify that the OS has the required service

packs or patches installed. If not, obtain the proper service packs and patches and install them.

2 Some iSCSI host adapters and iSCSI OS

drivers do not always automatically find new targets when plugged in or when forced to rescan. Reboot the hosts.

3 Check if the vendor has a new driver. If so,

install it.

Checking the applications

1 Verify that the application is running the latest

device drivers for the devices connected to iPBridge. If not, get the latest device drivers and install them.

2 Verify with the application vendor if the iSCSI

technology is supported on the version of the application being used.

Troubleshooting

Page 32

Performance issues

If the host is not getting the performance it should, check the following items.

Checking SCSI devices

1 Verify that the devices are running at their

highest possible SCSI speed. Refer to SCSI

configuration commands on page 47.

Mixing SE and LVD devices on the same SCSI bus forces the speed of the bus to SE, thus slowing faster LVD devices. The iPBridge cannot accelerate an already slow device. Refer to Connecting SCSI devices to SCSI

ports on page iii of the Appendix.

2 Verify that the proper terminator is being used.

An SE terminator forces the SCSI bus to SE speeds.

Checking iPBridge SCSI ports

1 Verify that the SCSI port configuration is set to

the highest speed using the ATTO ExpressNAV interface or CLI. Refer to SCSI configuration

commands on page 47.

The iPBridge SCSI port speed, wide negotiation, and sync negotiation settings all affect the speed of the port. By default, these settings are set for optimal speed.

2 Verify that the SCSI devices are equally

distributed between the SCSI ports. Refer to

Alternative interface options

Optimal performance is seen when only two high-speed SCSI devices are connected to each SCSI port.

on page 33.

Checking iPBridge Ethernet ports

1 Verify that the data ports are set to auto

negotiate or forced to 1000 Mbs. Refer to

Ethernet Port Configuration

2 Verify that the MTU size is set to optimal setting

for the LAN/WAN environment.

Refer to Ethernet Port Configuration

23. The current optimized frame size for the iPBridge is 9k. Smaller frame sizes cause a decrease in performance.

3 Verify that the iPBridge

Checking the LAN/WAN

1 Verify that the MTU size is set to optimal setting

for the LAN/WAN environment. Refer to

Ethernet Port Configuration

2 Verify that each associated port in the IP SAN

is configured for 1000Mbs.

IP SAN traffic should be segmented so that it does not interfere with the main LAN network traffic.For better performance, the IP SAN should be on its own set of hardware.

3 Verify that packets are not being dropped along

the LAN/WAN. Many utilities track packet activity and switch statistics.

on page 23.

Checking Ethernet Host Adapter or NIC

Ethernet Storage Adapters generally outperform accelerated NICs and un-accelerated NICs by offloading most of the processing from the host.

An accelerated NIC provides some offloading, but still requires a host OS iSCSI driver, making the host spend more CPU cycles.

An un-accelerated NIC does not offload anything so the CPU must do much of the processing.

To check the Ethernet host adapter or NIC

1 Verify that the adapter or NIC is sent to auto-

negotiate or forced to 1000 Mbs.

2 Set the MTU size to the largest MTU size

supported in the LAN/WAN. Refer to Ethernet

Port Configuration on page 23.

9k frame size is the current optimized frame size for the iPBridge. smaller frame sizes cause a decrease in performance. Many switch and router vendors do not support the larger frame size of 9k or 16k. Set the maximum transfer size to the most efficient size for the intended target(s). For many tape drives, 64k is the optimal setting.

Checking the applications

Some applications can be configured to change transfer sizes. Configure the application for the optimal size for the particular SCSI device(s) connected to the iPBridge.

ATTO Technology Inc. iPBridge Installation and Operation Manual

Page 33

Checking the host system

The faster the host, the faster your transfer times are. The work flow goes only as fast as the slowest connection in the host system, so transferring data from an IDE drive, 100Mb connection, a DLT 4000, a high speed RAID volume across the country, or other applications, slows the system no matter how fast everything else is in the system.

1 Verify that the iSCSI storage adapter or NIC is

connected to the fastest PCI bus connector supported by the adapter or NIC.

If the adapter supports PCI-X, place the adapter in a PCI-X slot. If one is not available, the host might not achieve the optimal performance capable from the adapter.

Even placing a PCI-X adapter into a 64 bit 66 MHz slot loses performance. Some adapters

adjust clock speed depending on the speed of the PCI slot into which they are plugged.

2 The host OS disk and swap disk/partition/file

should be on a high speed drive such as a SCSI drive to minimize the time needed to access the host’s virtual memory.

The more memory a system has, the less time it spends accessing virtual memory (hard drive space).

Checking the Operating System

If possible, eliminate swap space and virtual drives which require large amounts of system memory. However, the OS might not allow the elimination of swap space. An OS set to run many kinds of different servers spends much of its CPU cycle on other operations, thus slowing down performance.

7.1 CLI provides ASCII-based interface

The command line interface (CLI) provides access to the ATTO iPBridge Services through a set of ASCII commands. CLI commands may be entered while in CLI mode.

iPBridge Services provide configuration and monitoring for the iPBridge. CLI commands may be entered while in CLI mode or on the ExpressNAV interface

• CLI commands are context sensitive and generally follow a standard format

[Get | Set] Command [Parameter 1 | Parameter 2]

followed by the return or enter key

• CLI commands are case insensitive: you may type all upper or all lower case or a mixture. Upper and lower case in this manual and the help screen are for clarification only.

• Commands generally have three types of operation: get, set and immediate.

• The get form returns the value of a parameter or setting and is an informational command.

Responses to get commands are specified in the

Results field for each command, followed by Ready.

Advanced CLI

page.

• The set form is an action that changes the value of a parameter or configuration setting. It may require a SaveConfiguration command and a restart of the system before it is implemented. The restart can be accomplished as part of the SaveConfiguration command or by using a separate FirmwareRestart command. A number of set commands may be issued before the SaveConfiguration command.

Responses to set commands are either an error

message or Ready. *. The asterisk indicates you must use a SaveConfiguration command to finalize the set command. SaveConfiguration asks if you want to restart the system or not.

• Commands which do not require a SaveConfiguration command are immediately executed.

Responses to commands are either an error

message or data results followed by Ready.

For an example of a typical CLI command and response, see Exhibit 7.1-2 on page 32.

Appendix B Cabling

Additional information to physically connect ports to devices and to your SAN.

SCSI cabling

Cables and devices must be chosen to maximize performance and minimize the electrical noise from the high-speed data transfers available with the SCSI protocol. Cabling and termination methods become important considerations for proper performance. SCSI cables and devices are subject to specific length and number limitations to deal with electrical problems that arise at increased operating speeds.

Examples

The SCSI specification limits total bus cable length for single-ended SCSI in a non-UltraSCSI environment to 3 meters (combined length of both internal and external cable lengths).

In an UltraSCSI workgroup environment with a 7drive tower, you are limited to 1.5 meters between the host and the tower, including the cabling for the tower. If the 7-drive tower requires 1 meter of cabling to connect all of its drives, the distance

Cable types

from the tower to the host must be .5 meters.

Use high-quality cables rated for the type of SCSI transfers required: well-insulated SCSI cables ensure error free communications. Try to keep cable lengths as short as possible to ensure higher signal quality and performance.

Exhibit 0.0-1 Various types of SCSI operate at different speeds and require different bus lengths to support a certain number of devices.

Connecting SCSI devices to SCSI ports

ATTO iPBridge SCSI ports connect SCSI storage devices to the network. Each SCSI port is completely independent from the other SCSI port.

Each SCSI port is a bus capable of supporting 15 devices and each bus is capable of 40, 80, 160 or

iii

ATTO Technology Inc. iPBridge Installation and Operation Manual

520 MB/sec. (Ultra, Ultra2, Ultra 160 or Ultra

320) transfer rates.

You may use externally provided striping software to create a RAID 0 group that includes devices from both SCSI busses to increase overall performance.

Page 67

Each SCSI bus auto-negotiates the appropriate sync rates with the connected devices. If slower devices are mixed with faster devices, the bus communicates at the rate of the slowest device, thus wasting the performance capabilities of the faster devices. Connect slower devices to one SCSI port and connect faster devices to the other port.

The iPBridge supports a wide variety of SCSI storage devices including stand-alone drives, removable drives, JBODs, RAIDs, tape, CD and DVD drives, changers and libraries.

1 Connect the cable from the SCSI device to a

VHDCI SCSI port on the iPBridge.

2 Check the type of cable, cable length limit and

number of devices recommended for the port. See Exhibit 0.0-1.

Keep cable lengths as short as possible to

ensure the highest signal quality and performance. These cable lengths include the wiring inside the devices.

3 Set the IDs of the SCSI devices connected to

the bridge to a value other than 7.

Use a sequential ID starting at 0 for each

device. The SCSI port in the ATTO iPBridge has an internal factory setting ID of 7, typical for a SCSI initiator device.

Note

The entire SCSI bus operates at the speed of the slowest device on that bus. If you wish to mix devices of different SCSI speeds, place the devices on separate busses. That is, put the slower devices on iPBridge 2500 SCSI bus 0, and the faster devices on iPBridge 2500 SCSI bus 1. Each bus is independent so each can operate at different speeds.

Terminate the SCSI bus after the last device. The iPBridge is terminated internally.

Ethernet connections

Use at least Cat 5e cable to connect the Ethernet ports to your network.

Note

For best performance, all cabling, network interface cards (NICs), host bus adapters (HBAs), and network switches must be Gigabit Ethernet (GbE), and at least Cat 5e certified. Most standard offices use 2-pair wiring which is not compatible. GbE requires 4-pair wiring.

For best performance, support for 9014 byte jumbo frames should be available for all switches and host iSCSI equipment.

Before you begin installing the iPBridge Ethernet ports, be sure to check or complete the following:

• If you are managing your iSCSI system across a

WAN and your system uses a firewall, be sure that the following ports are open and available:

If you are using the TCP protocol

• telnet (port 23)

• http (port 80)

• ftp (ports 20 and 21)

• iSCSI (port 3260)

• iSNS (port 3705)

If you are using the UDP protocol

• ntp (port 123)

• Be sure your host system(s) is set up and configured.

• Your host system can use any of three different types of cards: a network interface card (NIC), a TCP/IP offload engine card (TOE), or a storage network interface card (SNIC).

• The ATTO driver file from the CD included with your iPBridge or from the ATTO website, www.attotech.com, is installed on your host.

• The switch has been configured to forward UDP broadcast messages.

• The minimum requirement for Windows-based browsers is Internet Explorer 5.5 or Netscape Navigator 6.2. The minimum requirement for Macintosh browsers is Internet Explorer 5.2 or Safari 1.2.

• Ethernet speed defaults to auto; the iPBridge determines the speed and set other parameters based on the speed.
