ATTO Technology, Inc. ATTO FibreBridge Installation & Operation Manual
Chapter 1: INTRODUCTION
This manual will provide an overview of the various ATTO FibreBridge products and product modules as well as describe how to install and configure the bridge for optimal operation. The following products will be discussed:
• FibreBridge 2100R – Rackmount bridge module
• FibreBridge 3200R – Rackmount bridge module
• FibreBridge 2200R/D – Rackmount or Desktop bridge
• FC Rack System – Rack enclosure to hold the FibreBridge modules
Many features and procedures are similar amongst the FibreBridge modules. This manual is written to cover all of the products listed above. Differences will be called out when necessary.
FibreBridge Product Module Description
As a recognized leader in SCSI & Fibre Channel technology, ATTO takes proven SCSI technology and combines it with Fibre Channel to allow end users to leverage investments in current SCSI equipment while benefiting from the advantages of Fibre Channel.
FibreBridges provide a means of attaching parallel SCSI devices to a Fibre Channel arbitrated loop or fabric. They efficiently pass SCSI commands between the Fibre Channel bus and independent SCSI busses, manage the transaction between the two architectures and maintain the internal integrity of the unit. The FibreBridge simply communicates with Fibre Channel initiators and SCSI targets. Therefore, it is operating system independent.
ATTO FibreBridge Product Modules (models 2100R and 3200R) are designed to be installed into the ATTO FC Rack System. Combined, the bridge product modules and rack system are intended for high reliability, availability and serviceability environments.
The FibreBridge 2200R/D product is ideal for installations where high availability is not as much of a concern as cost. This bridge provides all of the features and functionality of the other products, except it is designed to be a stand-alone unit. It does not get installed into the FC Rack system, and therefore does not have redundant power supplies or cooling systems. The power supply and cooling system are designed into the enclosure. This enclosure was designed for operation on either a desktop/table or in a 19” rack. Two “L” brackets are included for installation into a rack.
FC Rack System Product Description
The ATTO FC Rack System is a configurable 19” rack system with two bays designed to house ATTO’s Fibre Channel product modules. The 1U-rackmount enclosure provides the flexibility to integrate the ATTO FibreBridge ™ Product Module and the ATTO FibreCenter™ Product Module together, separately or in pairs.
The following items are included with the ATTO FC Rack System:
• Up to (2) ATTO FibreBridge Product Modules.
• One (1) or two (2) Power Modules.
• One (1) or two (2) AC shielded power cord(s).
• Two (2) Rackmount “L” brackets and (4) screws for mounting the unit into the rack.
If any of these items are missing or damaged, please contact an ATTO Technology Authorized Sales Representative.

Fibre Channel Technology
Fibre Channel is a serial communications interface designed for the transfer of large amounts of data between a variety of hardware systems over long distances. It is becoming a key technology for applications that require shared, high bandwidth access to storage.
Fibre Channel provides a logical point-to point serial channel for the transfer of data between a buffer at a source device and a buffer at a destination device. It moves buffer contents from one port to another, without regard to the format or meaning of the data. In this way, Fibre Channel allows different upper level protocols such as SCSI-3 to run over Fibre Channel hardware.
The Fibre Channel architecture is structured as a hierarchical set of protocol layers. Defined within these layers are the rules for signal interfaces, serial encoding and decoding, error control, frame format and communications protocols. Fibre Channel provides a range of implementation possibilities and purposely isolates the transmission medium from the control protocol so that each implementation may use a technology best suited to the application environment.

ATTO FibreChain
™
ATTO's exclusive FibreChain expansion ports enable both the ATTO FibreBridge and ATTO FibreCenter (hub) Product Modules to be daisy chained together in the same arbitrated loop on a fixed cost per port basis, thus reducing total cost of ownership. ATTO Technology provides FibreChain cables for these ports. ATTO FibreChain ports are not compatible with standard Fibre Channel cables.
Fibre Channel Switch Support
All models of the FibreBridge can be configured to support connectivity to arbitrated loop or fabric topologies.
The FibreBridge 2100R uses Public Loop Login for connection to FL_Ports on fabric switches and is not compatible with F_Ports. The FibreBridge 3200R and 2200R/D have the ability to log into F_Ports as well as FL_Ports on switches. Some older model switch ports have separate F_Ports and FL_Ports. Be sure to connect the Bridge to the appropriate port. Some newer switches have the ability to detect if a device

can support F_Ports or FL_Ports and automatically configure itself. ATTO Technology recommends that this mode of operation not be used. It is better to force the port to the desired mode.
When connecting the bridge to a F_Port device, set the port connection mode to “Point-to-Point.” When connecting to a FL_Port device, set the port connection mode to “Loop”. The port connection mode of the bridge can be set using the RS-232, Ethernet, or in-band ATTO BridgeTools communication links.

Chapter 3: ATTO FC Rack Enclosure and Power Modules
This chapter provides an overview of the ATTO FC Rack System and the Power Modules, as well the installation process for the Power Modules. The main enclosure of the ATTO FC Rack System houses all the FibreBridge™ Product Modules and Power Modules. There are two bays for FibreBridge Product Modules and two bays for Power Modules.
Physical Dimensions
Figure 3.1 Rear view with dual redundant power supplies
The physical dimensions of the ATTO FC Rack System are
17.4" W x 17"D x 1.72"H (441.6mm W x 431.5mm D x 43.7mm H)
Mounting
The ATTO FC Rack System can be installed with the ATTO Product Modules facing the front or the back because the "L"-brackets can be installed on either end. The mounting holes on the "L"-bracket fit a standard 19” rack, using a centered 1.25” (31.7mm) hole pattern.

Figure 3.3 Side view with hole dimensions in inches (mm in parentheses)
Environmental
The ATTO FC Rack System is designed to operate in an environment that is 0°-40° C, 0-90% humidity and non-condensing.
Cooling Airflow
Each Power Module provides a total of 16 CFM of airflow. A system that has two Power Modules installed will have a total of 32 CFM of airflow. Air enters through the sides of the enclosure and is exhausted out
the Power Modules. Ambient air near the inlets should not exceed 40°C.
Cooling Fans
Each Power Module has two (2) 8-CFM fans, exhausting air out of the unit. The power for the fans is provided from the backplane. The backplane takes the power from both supplies and combines them so that a power supply’s fans will run whether or not the supply itself is operating.
WARNING: DO NOT BLOCK THE VENTS ON EITHER SIDE OF THE MAIN ENCLOSURE. BLOCKING THE VENTS MAY
CAUSE OVERHEATING AND COULD DAMAGE THE PRODUCT.

ATTO Technology, Inc. ATTO FibreBridge Installation & Operation Manual
Internal Power Distribution
The ATTO FC Rack System provides a redundant power scheme with two "hot swappable" Power Supply Modules. Each Power Supply Module feeds 12V to the backplane. From there, the power is distributed to the bridge modules and the fans.
A failure of one power supply will not affect the functionality of the bridge modules or the cooling system since the second supply is still supplying power to the backplane. In a redundant power supply installation, one supply can be removed and replaced without affecting the rest of the system in any way.
The Product Module is responsible for detecting power supply failures, voltage regulation, and failover. NOTE: Power Modules will load balance when there are two present in the ATTO FC Rack System
Power Module
The Power Module is a hot swappable unit that contains enough power to supply two ATTO Product Modules and four cooling fans. It is designed to slide into the ATTO FC Rack System enclosure, in either of the two bays, on the end of the rack enclosure that is closer to the backplane. This is the end that is farthest away from the cooling vents in the sides of the rack enclosure (see figures 3-1, 3-3 and 3-4).
The Power Module supplies power to the ATTO Product Modules. In addition it powers the fans for cooling. The Power Module contains a power supply with the following specifications.
• Input voltage: 110/230V AC, with an operating input range of 90-132V AC or 175-264V ac, 47- 63Hz, single phase. The AC input range selection is automatic. No manual jumper or switch over is required.
• Output voltage: +12 Volts @ 5 Amps (60 watts) continuous, 5.8 amps (70 watts) peak.
Figure 3.5 Rack System Power Module
ATTO Technology, Inc.
- 7 -
ATTO Technology, Inc. ATTO FibreBridge Installation & Operation Manual
• Power Draw: The maximum power draw is 2 Amps @ 110 Volts for the entire ATTO FC Rack System. When the ATTO FC Rack System has two Power Modules, the entire unit will still draw only 2 Amps @ 110 Volts.
LED Indicator
The green LED indicator on the Power Module will light when the module is correctly installed and the switch is turned on. This LED indicates that power is being drawn from this module and is available on the backplane. A Power Module that is turned on when not installed will not have the LED illuminated. It is not recommended and can be dangerous if the AC power cord is plugged in and the power switch is turned on with an uninstalled Power Module.
IEC Power Receptacle and Switch
The Power Module has one standard IEC320 power receptacle and switch for easy adaptability to different voltage standards throughout the world.
Installation and Removal
To install a power module: Step 1. Make sure the power switch on the rear of the power module is in the off position and the power
cord is disconnected. Step 2. Slide the power module into the rack enclosure until you feel it make contact with the backplane
connector. The face of the power module should be flush against the rack enclosure edges.
Step 3. Secure the power module by tightening the two thumb screws (hand tight). Step 4. Connect the AC power cord to the power module and plug it into an appropriate receptacle.

Step 5. Turn the power switch on the power module to the on position. Verify that the green LED is illuminated.
The correct method for removal of a power module is as follows: Step 1. The power switch on the rear of the power module must be in the off position. Make sure the
power LED is NOT illuminated.
Step 2. Disconnect the power cord from the power module as well as the AC power source. Step 3. Loosen the two thumb screws on the face of the power module. Step 4. Carefully slide the power module out of the rack enclosure.
ATTO FC Rack System Installation Considerations
• Operating Temperature – The manufacturer’s maximum rated ambient temperature is 40 C. Consideration should be given to installing the FC Rack system in an environment where this temperature could be compromised.
• Reduced Air Flow – Consideration should be given to installing the FC Rack system in an environment where the air flow required for safe operation could be compromised.
• Mechanical Loading – Mounting of the FC Rack system should be that no uneven mechanical loading is imposed upon the FC Rack system.
• Circuit Overloading – Consideration should be given to the supply circuit to which the FC Rack system is connected. Overloaded supply circuits may have hazardous effects to the overcurrent protection and supply wiring and thus damage the FC Rack system and its modules. Appropriate consideration of the equipment nameplate rating should be used when addressing this concern.
• Reliable Grounding – Reliable grounding of the rack mounted equipment should be maintained.

Chapter 4: ATTO FibreBridge™ Product Module Integration
This chapter provides an overview of the ATTO FibreBridge Product Modules and their installation process.
ATTO FibreBridge module is designed to slide into and mount to either of the two module bays on the main FC Rack Enclosure chassis. The bridge module must be inserted into the face of the rack chassis where the cooling grids are located. The connector on the back of the bridge module is only used to supply a power and ground connection to the backplane of the rack enclosure.
Figure 4.1 ATTO FibreBridge Product Module
Environmental
The ATTO FibreBridge modules are designed to operate in an environment that is 0°-40° C, 0-90% humidity and non-condensing.
Cooling Airflow
The FibreBridge module cooled by external sources. Air enters through the sides of the module and is drawn out from the rear. Ambient air near the inlets should not exceed 40°C. The FC Rack system
provides a minimal of 16 CFM of airflow. A system that has two Power Modules installed will have a total of 32 CFM of airflow.
Power Requirements
The FibreBridge module has the following power supply requirements:
• Recommended Supply Voltage: +12 Volts @ 5 Amps (60 watts) continuous
• Power Draw: The maximum power draw is 1 Amp @ 110 Volts

Fibre Channel Ports
The Fibre Channel ports on the bridge modules are used to connect the bridge into either a Fabric or Arbitrated Loop. Some of the features for the Fibre Channel ports include:
• 1.0625 Gigahertz (100 MB/sec)
• Support for Class 2, Class 3, and Intermix ANSI Fibre Channel specifications
• Support PLDA, Public Loop Login (NL_Ports) as well as Fabric Direct Connect (N_Port)
• Support for Full Duplex transmissions
• Fixed DB9 copper ports that are MIA compliant or GBIC ports for DB9 copper, HSSDC copper,
short wave optical, or long wave optical interfaces
Refer to the comparison chart in Chapter 2 to determine which features apply to the models of the FibreBridge.
Some models of the FibreBridge can be configured to support connectivity to arbitrated loop or fabric topologies. When connecting these bridges to an F-Port device, set the Port Connection Mode to “Point­to-Point.” When connecting to a FL-port device, set the port connector mode to “Loop” mode. The ATTO FibreBridge uses public loop login to log into a FL-Port on a fabric switch. The port connection mode of the bridge can be set using the RS-232, Ethernet, or in-band ATTO BridgeTools communication links.
Other models of the FibreBridge only support Public Loop Login for connection to FL_Ports on fabric switches.
Some models of the FibreBridge come with two Fibre Channel ports to daisy chain bridges together, to daisy chain bridges to hubs, or to connect additional Fibre Channel drives without using valuable switch or hub ports. The implementation involves an arbitrated loop within the bridge. This means that if Fibre Channel port 1 is connected to a switch and port 2 is connected to an additional loop device, the Switch port must be configured as an FL_Port (loop mode). F_Port devices will not work in this environment. The FibreBridge must also be configured for “Loop Mode”. “Point to Point” mode will not work for daisy chaining.
The two Fibre Channel ports cannot be configured in a failover connection environment with switches in that it is not possible to have more than one switch port connected in this arbitrated loop. When using both Fibre Channel ports on the bridge, eac h port will need to be configured as a NL_Port. When devices are powered up, each NL_Port must sign in with the other ports on the loop. Each port first attempts to find a FL_Port within the loop. When it does, it knows it is a part of a public loop connected to a fabric. If it does not, it knows it is a part of a private loop consisting of other NL_Ports only. Arbitrated loops can have up to 126 active NL_Ports but only one active FL_Port because the FL_Port is considered the master. Having two switch ports (same switch or different switches) is illegal because there would be two FL_Ports.
At this time, the Fibre Channel ports only support initiator devices. A SCSI based host computer connected to the SCSI side of the bridge will not be able to communicate with a Fibre Channel drive connected to the Fibre Channel port.
SCSI Ports
The two SCSI ports on the bridge modules are used to connect storage devices into the Fibre Channel Storage Area Network (SAN). A FibreBridge can be ordered with any of the following types of SCSI ports:
• Ultra 2 (LVD) SCSI– 80 MB/sec max per bus
ATTO Technology, Inc.
- 12 -
ATTO Technology, Inc. ATTO FibreBridge Installation & Operation Manual
• Single Ended Ultra SCSI – 40 MB/sec max per bus
• High Voltage Differential (HVD) Ultra SCSI – 40 MB/sec max per bus
Each of the two ports is totally independent from the other. This means that each bus is capable of 15 devices and each bus is capable of 40/80 MB/sec (Ultra/Ultra2). There are a few advantages to this. First, you are able to use software striping to create a RAID 0 group that includes devices from both SCSI busses. This can effectively increase your overall performance to 80 MB/sec for Ultra SCSI or 100 MB/sec (the Fibre Channel bandwidth limit) for Ultra2 SCSI. Using ExpressRAID software from ATTO also gives you the ability to stripe hardware RAID controllers together. Another advantage is that each SCSI bus auto-negotiates the appropriate synch rates with the connected devices. If slower “Legacy” devices are mixed with faster Ultra2 devices, the bus will only communicate at the rate of the slowest device, wasting the performance capabilities of the faster devices. With the ATTO FibreBridge, it is possible to connect slower “Legacy” devices of one SCSI bus of the bridge while connecting faster devices on the second. Each bus can communicate at independent rates.
The ATTO FibreBridge supports a wide variety of SCSI storage devices including stand-alone drives, removable drives, JBODs, RAIDs, tape, CD and DVD drives, changers, and libraries, magneto optical drives, as well as Jaz and Zip devices.
FibreChain™ Ports (2100 model only)
The FibreChain expansion ports enable both the ATTO FibreBridge and ATTO FibreCenter (hub) Product Modules to be daisy chained together in the same arbitrated loop on a fixed cost per port basis, thus reducing total cost of ownership. The signal pin-out is different between standard Fibre Channel cables and FibreChain cables. ATTO Technology can provide the custom FibreChain cables for these ports.
The FibreChain ports are connected to the Fibre Channel ports on the same arbitrated loop internal to the bridge. When more than one FibreBridge is chained together, the loop is essentially being expanded. Two FibreChain
Fibre Channel
Port
ports are only necessary for chaining three or more bridges together.
FibreChain ports are limited in their functionality in that they do not re-time nor re-generate the
FibreChain Port 2
FibreChain Port 1
signals like a standard Fibre Channel port does. Because of this, FibreChain cables are limited in distance to assure signal integrity.

ATTO FibreChain™ Port LEDs (2100R model only)
There is a yellow LED adjacent to each ATTO FibreChain expansion port that will remain lit if the ATTO FibreChain expansion port is not being used (there is no connection to the port). When an expansion cable is connected and a link is established, the LED will go off. These LEDs will indicate cable connections only. They do not indicate cable signal activity.
LED Indicators
Power A, Power B – Two LEDs are used `to indicate if power is available from each of the two supplies. The ATTO FibreBridge only requires power from one of the sources in order to operate.
