WARNING

Never modify or remove the radio frequency interference shielding from your workstation or expansion unit. To do so may cause your installation to produce emissions that could interfere with other electronic equipment in the area of your system.

Preface

Advisories

Five types of advisories are used throughout this manual to provide helpful information, or to alert you to the potential for hardware damage or personal injury.

Disclaimer: We have attempted to identify most situations that may pose a danger, warning, or caution condition in this

manual. However, Magma does not claim to have covered all situations that might require the use of a Caution,

Warning, or Danger indicator.

Safety Instructions

Always use caution when servicing any electrical component. Before handling the Magma Expansion chassis, read the following instructions and safety guidelines to prevent damage to the product and to

ensure your own personal safety. Refer to the “Advisories” section for advisory conventions used in this

manual, including the distinction between Danger, Warning, Caution, Important, and Note.

authorized electronics personnel should access the interior of the computer and expansion chassis.

Magma

EB7-X8G2 |

CAUTION

Do not attempt to service the system yourself except as explained in this manual. Follow installation instructions closely.

Electrostatic Discharge (ESD) Warning

Electrostatic Discharge (ESD) is the enemy of semiconductor devices. You should always take precautions to eliminate any electrostatic charge from your body and clothing before touching any semiconductor device or card by using an electrostatic wrist strap and/or rubber mat.

When Working Inside a Computer

1. Before taking covers off a computer, perform the following steps:

2. Turn off the computer and any peripheral devices.

3. Disconnect the computer and peripheral power cords from their AC outlets or inlets in order to

prevent electric shock or system board damage.

In addition, take note of these safety guidelines when appropriate:

 To help avoid possible damage to systems boards, wait five seconds after turning off the computer before

removing a component, removing a system board, or disconnecting a peripheral device from the computer.

 When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some

cables have a connector with locking tabs. If you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before connecting a cable, make sure both connectors are correctly oriented and aligned.

Protecting Against Electrostatic Discharge

Static electricity can harm system boards. Perform service at an ESD workstation and follow proper ESD procedures to reduce the risk of damage to components. Magma strongly encourages you to follow proper ESD procedures, which can include wrist straps and smocks, when servicing equipment.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

 When unpacking a static-sensitive component from its shipping carton, do not remove the component’s anti-

static packaging material until you are ready to install the component in a computer. Just before unwrapping the anti-static packaging, be sure you are at an ESD workstation or are grounded.

 When transporting a sensitive component, first place it in an anti-static container or packaging.

 Handle all sensitive components at an ESD workstation. If possible, use anti-static floor pads and workbench

pads.

 Handle components and boards with care. Don’t touch the components or contacts on a board. Hold a

board by its edges or by its metal mounting bracket.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

CAUTION

Hardware installation shall be performed only by qualified service personnel per UL and IEC 60950-1.

Electrostatic Discharge (ESD) Warning

All PCI cards are susceptible to electrostatic discharge. When moving PCI cards, it is best to carry the cards in anti-static packaging. If you need to set a PCIe card down, be sure to place it inside or on top of an anti-static surface. For more information, see “Protecting Against Electrostatic Discharge” in the Preface.

WARNING

High voltages are present inside the expansion chassis when the unit’s power cord is plugged into an

electrical outlet. Disconnect the power cord from the AC outlet before removing the enclosure cover. Turning the system power off at the power on/off switch does not remove power to components. High voltage is still present.

CAUTION

Before touching anything inside the enclosure, move to an ESD station and follow proper ESD procedures. Failure to do so may result in electrostatic discharge, damaging the computer or its components. For more information, see “Protecting Against Electrostatic Discharge” in the Preface.

Chapter 2 Hardware Installation

The following steps will guide you through the installation of your Magma expansion system

Before you Begin

The system’s ATX power supply is auto-switching. This means that it will automatically switch to match whatever source power you are using. Since all products ship with a US/Canadian Standard 115V power cord, you will need to use a locally available power cord for non-US Standard power sources.

Remove Top Cover

Remove the four (4) screws from the back of the expansion chassis. Slide the enclosure cover backward to disengage it from the guides at the front of the enclosure by firmly grasping the edges of the cover lip and pulling the cover backward about 1” until it clears the front hold-down, and then lift the cover off.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

Check inside the unit, see if the Expansion interface card is installed. If the Expansion interface card is not plugged in, go to the next step “Install Expansion Interface card”. The pictures below are showing an EB7-X8G2 with Expansion Interface card installed.

No Expansion Interface card installed in the UPSTREAM SLOT as shown from the pictures below.

Install Expansion interface card (EIF)

” By default an EIF card should already be installed in the Magma expansion chassis.

Prior to installing the card, make sure the Dipswitch SW1 is set to ON position (ON=EXP) and Dipswitch SW2 is set to OFF position (x8 setting), see pictures below. The expansion system will NOT function if SW1 is set to OFF=HOST.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

SW1 and SW2

SW1 dipswitch should be set to “ON-EXP” position. SW2 dispswitches should be set to x8, see picture below.

Once the two dispswitches (SW1 and SW2) are set correctly, plug in the Expansion Interface card into the UPSTREAM slot. This is the designated slot for the Expansion Interface card only. You can not use other PCIe slots, the unit will not work properly.

Install Host Interface Cards

Install the Host Interface card. Begin the installation of your PCI Express (PCIe) host card by first powering down your computer. Use the procedures for shutting down your operating system and shutting off power to your system provided

in your owner’s manual or system documentation. The PCIe host card is a “half-height,” x8-capable PCIe card mounted to a “full-height” bracket as shown below.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

For low profile case applications, you may need to change the mounting bracket to the low profile bracket that shipped with your system. This is done by removing the screws that hold the card to the bracket. Be sure you are using proper ESD procedures when completing this action.

Installation of low profile bracket

Detach the standard bracket from the card, and place the low profile bracket and secure it.

Before installing the Host Interface card into PCIe slot, check the DIP switch settings.

 Check the red Dipswitch (SW1) on the Host interface card, make sure it is set to OFF= HOST.  Check the SW2 Dipswitch, both toggle switches should be set to OFF position (x8).

Once the dipswitches are set correctly and the host computer is off and all power cords are disconnected from the AC outlet, insert the PCI Express host card into a vacant x8 (or x16) PCIe slot by gently pushing the card until it is firmly seated. Then secure the card to the slot with a mounting screw.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

STOP

YOU MUST ONLY INSTALL THE PCIe HOST CARD INTO A PCI EXPRESS SLOT.

Only use cards WITH brackets. This will ensure that your PCIe host card can only be inserted into a PCIe

slot. Although PCI Express cards without brackets may fit into conventional PCI slots, you run the risk of damaging the PCI Express host card if you insert it into a PCI slot. Please ensure that your host computer has PCI Express slots and install the host card only into a PCI Express slot.

The illustratiob below shows what a PCI Express slots looks like in the computer’s mother-board compared to a standard PCI slots.

Install PCIe Cards

It is highly recommended to install third party PCIe cards / High Power PCIe cards after you have verified and tested that the Magma expansion chassis is functional and free of hardware failures. The next step is to connect the Ipass cable. For PCIe cards installation got to Chapter XX.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

Connect iPass Cable

The 1-meter iPass cable included with your Magma expansion chassis features a x8 connector on each side. Connect the iPass cable to Expansion and Host Interface cards. For the proper way of connecting the iPass cable to Interface card, see pictures below.

Carefully position the expansion chassis so that the supplied expansion cable will conveniently reach from the host

computer to the connectors on the back of the chassis. Connect one end of the iPass cable to the expansion chassis’

iPass connector. Then connect the other end of the iPass cable to the host card located in the host computer.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

How to Disconnect iPass Cable

Pull the green tab while slowly pulling out the cable from the Interface card. Failure to pull the green tab while disconnecting the iPass cable can break the connector inside the Interface card,

Connect Power Cord / Cable

Connect power cord to electrical outlet. Magma only provides the 110-120V power cord.

It is highly recommend using a power surge. This product is provided with a power supply that automatically adjusts to input voltages between 100 to 240 Vac. A U.S. and Canadian 125 V power supply cord is provided with this product. If using this product outside of the U.S. or Canada, please use locally available power supply cords.

Connect the AC power cord to the of back of the unit. Ensure that the system’s power supply unit is switched OFF before connecting the power cord.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

When done connecting the power cord, turn the power supply switch to ON position.

Upon turning the power supply to ON, the 3.3V AUX on the board is illuminated.

Power ON the unit

You must apply power to the EB7-X8G2 expansion chassis UUUBEFOREUUU you power up your computer. Press the front power button. When the unit is powered ON, the front Power LED indicator will illuminate.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

STOP

DO NOT TURN OFF THE MAGMA EXPANSION CHASSIS UNTIL YOU HAVE SHUT DOWN YOUR COMPUTER COMPLETELY! It can cause a system lockup and data loss.

Powering ON the expansion unit before the host, allows the higher numbered PCIe buses in the PCIe bus hierarchy to be at a stable state when the host system issues its master power-on bus reset. Upon powering ON the expansion unit, the following LEDs on the board are illuminated.

 3.3V, +1.5V , +3.3V Aux, +12v (Green in color)  Master RST LED (Amber in color)  Power LED : D1221 ( Green in color)

If the front Power LED indicator and 3.3V, +1.5V , +3.3V Aux, +12v LEDs are not coming ON, please check the power supply, make sure the switch is set to ON position and the power cord is firmly attached.

Power on the Host Computer

Before powering ON the computer, make sure the Host Interface card is seated correctly in the PCIe slot and the cable is firmly connected. During the boot up process or while the computer is starting up, the SLOT LED indicators will come ON and OFF. In this process we have not installed any PCIe cards, all PCIE slots are empty.

Shutting Down

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

Hardware Check

Once the host computer has booted all the way up, next is to check inside the expansion unit and verify that all LEDs are correctly illuminated. A fully operational expansion chassis will show the following LEDs lit on the backplane, Expansion Interface cards and the back of the unit.

1. LINKUP 0 LED is lot

2. Slot LEDs: 7 solid orange LEDs when no cards are installed). It should be OFF if slots are populated with cards

3. Expansion interfafe card LED: 5 solid green LEDs

4. Hot Plug LED next to Hot Plug buttons, should be all OFF unless the slots are populated with cards.

5. MASTER RST LED (D1217) and Power LED (D1221) should be OFF once the computer has established link with the

expansion unit.

LINKUP 0 LED

Once your computer started all the way up, you will see LINKUP lights appear on the back of the chassis near the iPass connector. The LinkUP 0 LED should be ON, solid green. 0 – Connection between host and chassis has been established.

Linkup 0 represents the EIF card connected “uplink” with the host’s HIF. The Linkup LEDs represent only an initial

connection/handshake between the chassis and host PC. A successful linkup doesn’t represent transfer or exchange of data. .

SLOT LEDS

You should see 7 LEDs that are illuminated as “orange” or “amber” behid the slots. This represents that there no cards installed in the corresponding slot. As shown from the picture below, all 7 slots are not populated with PCIe cards and the corresponding LEDs are illuminated as orange / amber.

Magma

EB7-X8G2 | Chapter 2 Hardware Installation

Expansion interfafe card LEDs

The Expansion Interface card will show 5 solid green LEDs illuminated. The normal LED indicator on the Expansion Interface card should display 5 solid green LEDs, this signifies that unit is trained / linked to x8.

Hot Plug LED (next to Hot Plug buttons)

Hot Plug LEDs should be off once the computer has booted all the way up. In this instance there are no PCIe cards, so it is normal for Hot plug LEDs to be off.

 D39, D34, D24, D20, D33, D25, D21>> should be OFF, when all the slots have no PCIe cards installed  D39, D34, D24, D20, D33, D25, D21>> should be ON as green, when all slots are populated with PCIe cards

MASTER RST LED & Power LED

The MASTER RST LED (D1217) and Power LED (D1221)on the expansion board should be OFF once the computer is linked with expansion unit.

Magma

EB7-X8G2 | Chapter 3 Software Installation

STOP

Before installing drivers, you should ensure that you have a current system backup of all of your important data.

Failure to follow these instructions exactly could result in a system lock-up and potential loss of data.

You must also disable your anti-virus software before continuing.

Chapter 3 Software Installation

Software Driver Installation

Magma Driver is not required for Windows 7, which means no manual installation of Magma driver. Windows 7, Windows 8, Windows 10, Windows Server Operating Systems and a non-Windows OS such as Linux and Unix based Operating Systems

You should first install your 3rd Party card and connect the system as described earlier in this chapter.

Before attempting to install anything on a Windows system, you should ensure that you have set a Restore Point, that all data files are closed and that you have a current backup of your data.

Verify Magma Installation

Windows 7, 8 and Windows 10

As your Windows computer starts up, you will see a small message box pop-up in the lower-right corner of the screen to alert you that Windows has found new hardware.

The system does not require any Magma drivers in order to operate properly with the x8 PCIe Host card.

To verify a successful installation on Windows, find the ‘My Computer’ icon and “right-click” on it. Then select ‘Manage’ from the pop-up menu. Next, click on ‘Device Manager’ in the leftmost Computer Management window. Finally, click on the View Menu and select View Devices by Connection.

Magma

EB7-X8G2 | Chapter 3 Software Installation

Open ACPI (BIOS)  Open PCI Bus Click the ‘+’ sign several times until your reach a PCI Express Root Port with a PCI Standard PCI-to-PCI Bridge beneath it.

When installed properly, you will see eight PCI Express standard Switch Ports below the system’s PCIe Root port.

If the verification is successful, you may now proceed to Chapter and install 3P

Party PCIe Cards as well as auxiliary peripherals, such as hard drives into the chassis. If, however, the installation was unsuccessful, you may not see the PCI to PCI Bridge or PCI Express standard Switch Ports below the PCI Express Root port . In that case precede to Chapter 6 for Troubleshooting installation problems.

Mac OS X

When using Mac OS X no additional software or drivers are needed. The operating system should automatically recognize the Magma host card and expansion chassis.

In Mac OS X, the Magma expansion device is transparent to the Operating System; it means that there will be no Magma hardware / device appearing in the Apple System profiler via PCI card. Only the PCIe cards will be recognized / detected. To verify whether the expansion unit is working or not is by installing a PCIe cards into the available PCIe slot. If the PCIe cards are recognized / detected, it means that the Magma expansion chassis is working.

Expansion Slot Utility

The following screen may be displayed the first time you turn on your computer with the Magma EB7-X8 installed. This is applicable to Mac OS 5 to Mac OS 7. Choose OK.

Magma

EB7-X8G2 | Chapter 3 Software Installation

Mac Operating System is prompting you to choose a PCI Express profile that maximizes the performance of your attached devices. The Magma host card can communicate up to a bandwidth of x8 to and from the expansion chassis and devices. You should choose a profile that matches the configuration of all the cards installed in your Mac. Magma recommends that you install the system host card into a x8 slot in order to maximize throughput.

In this example, the Magma host card is installed in slot 4 and appears as “Intel PCI-to-PCI Bridge Card”.

If your computer did not automatically prompt you to choose a PCI Express profile, you can locate this utility under System  Library  CoreServices  Expansion Slot Utility.app.

Apple System Profiler

When using Mac OS X no additional software or drivers are needed. As long as you are using Mac OS X Version 10.4 or newer, the operating system should automatically recognize the Magma expansion chassis.

Select “About This Mac” under the Apple Icon

Magma

EB7-X8G2 | Chapter 3 Software Installation

Then click the “More Info” button  click on System Report select PCI as shown below:

Upon selecting the “PCI Cards”, you should see all the available PCIe cards that are in the expansion unit. The Magma

devices are transparent to the Operating System, you will only see the PCIe cards that are in the expansion slots.

If any of these devices are not displayed as shown above, you should shut down your system (computer first, then the expansion chassis) and reconnect the cables and the PCIe expansion host card to ensure that you have a solid connection. Then restart the Magma expansion chassis followed by the computer. Next, try to verify the installation again, as shown above. If you are still having problems, contact Magma Technical Support at (858) 530-2511.

Magma

EB7-X8G2 | Chapter 3 Software Installation

RedHat Linux

Once the EB7-X8G2 has been installed in a RedHat9-based system, its installation can be verified by typing the following command lines:

lspci –t Displays the overall structure of the PCIe expansion system

lspci –vv Lists additional information about the PCIe switch (in our case it will list the Integrated Device Technology (IDT)

information.

Ispci –vvv Displays the most comprehensive information about the expansion system.

Typical output from lspci –vvv is verbose, but you can dig through the information to find very important information. There are so many registers and settings associated with PCI Express Switches.

Use the “lspci -vvv| grep “IDT” command to check that the Magma card and slot devices are detected (see image below). IDT is the PCIe switch (component) on the Magma expansion board.

You can alsouse the “lspci –vvv | grep “807”. The vendor ID for IDT PCie switch is 8077

The first PCI Bridge in this example is the Upstream Port. The ‘Downstream” ports are the remaining are the PCIe slots.

Magma

EB7-X8G2 | Chapter 3 Software Installation

To check the details of the Magma Upstream Port on Bus 1, Device 0, Function 0 (01:00.0), type “lspci –s 01:00.0 –vvv” command on the terminal window. The Bus number will change depending on the Server and location of host card. Below is the output of “lspci –s 01:00.0 –vvv”, there are several important information you need to check and these are the Link speed, port#, slot# and Bandwidth. There are commands to use to extract this information, go to “Linux

IMPORTANT ORDER OF PCI EXPRESS SLOTS

The PHYSICAL PCI Express Slots 1 – 7 are not in order when displayed in any Operating Systems Device information.

Mapping Physical Slot locations to port locations using lspci

How do you locate your PCI Express Devices in our Magma Chassis? And how does that correspond to physical slot locations?

Below is an example of 7 PCI Express Upstream and Downstream Ports in our Magma Chassis. This output comes from

lspci –vvv > info.txt. It has been cleaned up for this example. The Magma Chassis is located below under Bus 01. There are 7 downstream ports on Bus 2, each port has a number starting with 2, 4, … up to 14. The Bus number will change

depending on the Server and location of host card. Each port is associated with a physical slot number, 1 through 7.

EB7-X8G2 | Chapter 4 Install PCIe Cards

CAUTION

Hardware installation shall be performed only by qualified service personnel per UL and IEC 60950-1.

IMPORTANT

We will provide reasonable technical support with 3P

Party PCIe cards. However, if you have verified a successful installation of the MAGMA expansion system (as defined in HHHUUChapter 3)UUHHH, but experience difficulty installing your 3P

Party PCIe cards, the card manufacturer should be able to provide the best support.

Chapter 4 Install PCIe Cards

This chapter provides information on how to install 3P

on the installation of individual cards are provided by the card’s manufacturer. This chapter is provided as a simple

guide to help you install your PCIe cards in the chassis.

For the purpose of installation, the MAGMA expansion chassis functions exactly as a standard desktop computer chassis. Always follow the manufacturer’s instructions for installing their card or hard drive on a desktop computer.

Party PCIe cards into your MAGMA expansion chassis. More details

Open PCIe Expansion Chassis

In order to remove the lid off the chassis unlock the back thumbscrews and slide the lid towards you as shown below:

After removing the lid you will note the card hold-down bar as shown below:

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

Electrostatic Discharge (ESD) Warning

All add-in cards are susceptible to electrostatic discharge. When moving cards, it is best to carry the cards in anti-static packaging. If you need to set a circuit card down, be sure to place it inside or on top of an anti-static surface. For more information, see “Protecting Against Electrostatic Discharge” in the Preface.

WARNING

High voltages are present inside the expansion chassis when the unit’s power cord is

plugged into an electrical outlet. Disconnect the power cord from the AC outlet before removing the enclosure cover. Turning the system power off at the power on/off switch does not remove power to components. High voltage is still present.

In order to access the add-in PCIe cards, you will need to remove that bar as follows:

1. Rotate the plastic pieces until their grooves are aligned with the cards.

2. Unscrew the captive screw, lift up and remove the apparatus.

3. Tighten the screw in the black plastic piece to lock it into place and prepare it to lock the PCIe add-in card that will

be installed. Reinsert the bar into the chassis and tighten the captive screw.

Install PCI Express (PCIe) Cards

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

CAUTION

Before installing add-in cards, please ensure that the input current rating specified on the AC input label is not exceeded.

When installing 3rd Party PCIe cards into the Magma expansion chassis, it makes no difference which PCIe slot you place your cards in. Usually that is determined by accessibility and heat dissipation consideration as may be specified by the card manufacturer.

Be sure to install the PCIe cards following the card manufacturer’s recommendations. Some PCIe card manufacturers recommend that you install their software driver(s) prior to installing the hardware. If this is the case, you should install their driver before you connect and power up the expansion chassis.

Make sure that all PCIe cards are fully seated in their connectors. When correctly seated in its connector, you will notice a firm resistance when you pull up gently on the card. To keep the cards in place, secure them in the enclosure with their retaining screws (supplied with the MAGMA expansion chassis).

After securing the cards verify that they do not touch each other. Depending on PCIe card size and thickness, you may require mechanical card guides to ensure isolation, such as the case with 2 single full-length PCIe cards. Card guides for this system can be purchased separately from Magma.

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

IMPORTANT

The sheer number of PCIe cards and device drivers available makes it impossible for Magma to fully test and certify all available PCIe cards for use in the MAGMA expansion chassis. Our best advice to you in this regard is to insist on full PCIe Specification compliance from your card and system vendors. Cards and systems should be at least PCIe Specification Revision 1.0 compliant or better. Compliance in your system motherboard, PCIe cards, and console firmware (or BIOS) is your best assurance that everything will install and operate smoothly.

System Should Be Up and Running

Apply power to the MAGMA expansion chassis first, then power up the computer.

Use the procedures detailed in UUChapter 3UUHHH to confirm the card installation(s) in the Windows Device Manager or Apple System Profiler. When everything is functioning correctly, your Windows Device Manager should look something like this:

SNMP Features and Configuration

This is only applicable to Magma’s EB7-X89G2-RAS chassis

SNMP Features

Magma’s EB7-X89G2-RAS chassis supports the Simple Network Management Protocol for remote monitoring and administration by offering the following features:

 Internal Temperature monitoring  Clear Alarm button monitoring  Swappable fan status (for fans 1,2,3 and 4 in the front)  Power supply 1 status  Power supply 2 status  10 Traps are defined to alert the SNMP server in case of overheats or failure in any of the subsystems mentioned

above.

 Remote chassis turn on

 Input/output switching

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

CAUTION

Aside from reading an IP address, the IPsetup.exe utility can be used to set an IP address other than the one assigned initially by the DHCP server—using the Set button. It is recommended, however, not to use the utility for this purpose since we will lose connectivity with the chassis until the machine running IPsetup.exe obtains an IP address in the same IP subnet. The next section will show a preferred way of accomplishing this via the browser interface. In case you need to back-trace any of these steps, you can always reset the chassis back to its factory settings.

SNMP Configuration

To ensure that you can successfully monitor your new system, you will need to connect it to a local or private hub using a standard RJ-45 Ethernet Cable. Connect one end of the cable to the RJ-45 port, located to the right of the power supply modules, and the other end to your local area network connector. In case you connect the chassis to a local computer/laptop is sure to use a Hub with a regular network cable or a crossover cable without a Hub.

The SNMP module in the EB7-X8G2-RAS system is configured for DHCP access (though this setting can be changed as described in the next section). Once the chassis is

turned on it will be assigned an IP address by your network’s DHCP server.

If you have access to your network’s DHCP server make sure to look up and write down

that IP address. In any other case you will need to use the IPsetup.exe utility to discover the IP address that was assigned to the chassis. It can be downloaded in the SNMP section of the Magma driver downloads at: http://www.magma.com/drivers.asp

Double click on the utility icon after your chassis has been connected to the network and powered on. It will then identify your chassis based on its MAC address and display the following information.

In this case the IPsetup utility has found the EB7-X8G2-RAS chassis at IP address 192.168.1.10.

To verify we’ve successfully detected the EB7-X8G2-RAS on our network press on the Launch Webpage button or open your browser and direct it to the new found IP address of the chassis (in our case it will be: http://192.168.1.10).

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

Configure Network Settings

Open your browser and enter the IP address in the URL window and press Enter. The following browser window will open up:

The initial, Generic Info page provides status information and no username or password is required. If the main power switch is off, then this page will show the IP Address that is currently assigned to the chassis, the IP Address that will receive trap information, the temperature settings and that the chassis is powered off. To make changes to your settings

you will need to follow the “IP Configuration” link. The IP configuration page is password protected and before access is

given the following dialog will appear:

The factory settings define User name to be “default” and the password to be “magma”. Enter these values in the appropriate field and click OK. If the username and password have not been changed from the factory settings, the IP Configuration page will appear as shown below. If it doesn’t, see your network administrator for the correct user name and password.

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

To change the IP address, enter the new static IP address in the IP Address field. Enter the new subnet mask in the Network Mask field. Enter the IP addresses for the Gateway and the DNS Server in the appropriate fields. Finally, enter a new network name for the EB7-X8G2-RAS in the DHCP Device Name field for use when accessing the chassis when DHCP is enabled. If you wish to use DHCP, enter 0.0.0.0 in the IP Address field, but be sure you have the tools and proper network privileges to access the system after a server had assigned it an IP address.

When you have finished configuring the network settings, you can either configure the SNMP settings as described in the next section, change the default user name and password, or save the current changes by clicking on the Save Network Configuration button at the bottom of the screen.

Now you can connect your chassis to the network. To find the IP address assigned by your DHCP server, look in the DHCP server’s list of attached devices for the name you assigned to your EB7-X8G2-RAS chassis.

Configure SNMP Settings

If you are adding your EB7-X8G2-RAS chassis to an existing SNMP network, or if you are planning to trap SNMP errors, you will need to configure the SNMP settings for use with your SNMP agent.

To configure these values for your SNMP network, select the SNMP section on the top bar and change the default values to match your requirements.

Change the Read Community Name and Write Community Name fields to match those required by your SNMP network. The default value is public.

Change the Trap Destination IP Address to the IP address of the computer getting the SNMP data. The default Trap Destination IP address in the above example was: 192.168.1.2.

Finally, save the newly entered settings:

Temperature settings

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

IMPORTANT

The user name and password fields are case-sensitive.

In the Temperature section you can view in real time the temperatures inside the chassis. Should the temperature rise above the set limit, the respective value will be shown in red, an audible alarm will be triggered and the temperature LED in the front control panel will turn orange (see example below concerning Main Temperature 3 exceeding its limit):

Change Credentials

This section allows you to change the default user name (default) and password (magma).

To change the user name, simply enter your new user name in the user name field. To change your password, enter your new password in the password field. Enter it again in the password(again) field. The password in both fields must match before they can be accepted.

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

When you have finished changing the default user name and password save the current changes by clicking on the

Save New Credentials button at the bottom of the screen:

Reset to Default Values

You can restore your EB7-X8G2-RAS chassis to the factory default values by pressing and holding the Alarm Reset Button for 10 seconds the Power LED will blink during this 10 second period. When all values have been restored, the LED will stop blinking and turn off.

Configure your SNMP Agent

If you use an SNMP agent to help you monitor your network, you will find all necessary monitoring information in the MIB file.

Retrieving the MIB File

The MIB file is available for download at: http://www.magma.com/drivers.asp in the SNMP section of that page.

After you click on the MIB file link, save the file as type “All Files” to your preferred location. You may then open the file (using Notepad, or equivalent text editor) and all the information needed to configure your SNMP agent will be displayed on the screen:

Once the MIB file is saved it can now be copied and loaded locally or to a remote server.

Accessing the various SNMP functions

Once the MIB file has been loaded to an SNMP server (via a front-end software typically called a MIB Browser) we can read in status information and set up specific functions otherwise not available via the Web interface.

The MIB Browser (or equivalent front-end SNMP software) will display the Magma chassis MIB contents in an explorer-like, Tree interface. A snapshot from the MIB Browser by iReasoning is shown below:

Under the MIB Tree, the Magma Chassis will have status information that can be read by expanding the respective folders. This information is also available in the Web interface mentioned previously. In addition, if we expand the sendAction folder (as shown above) we gain access to “writable” functions that essentially allow us to remote-control the chassis.

Remote Chassis Reset (turnPowerOffOn)

This function allows us to remotely turn the chassis off and on.

Right-click on it, and an options menu will appear. Select the “Set “command:

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

IMPORTANT

In order to successfully apply this function you must first set the SNMP Power-on

Jumper in the position between PS_ON and ON_BY_MCU. This is not the default

position of that jumper. Additionally, the chassis’ master on/off switch as well as each of the redundant

power supplies’ switches must be turned ON.

I/O Switching

The SNMP interface allows us to configure voluntary I/O switching so that the resources offered by PCIe cards installed in the Magma chassis can be rolled from one PC to another in real time. To access this feature, click on the I/O Failover link as shown below:

For more information on this feature see Appendix B: I/O Switching

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

IMPORTANT

For this feature to work, you need to install the Magma HotPlug software driver. See Chapter 2 for instructions on how to download the latest software for your system.

IMPORTANT There are cases in which you would wish to turn off this feature, especially if the

PCIe cards you plan on installing in the EB7-X8 chassis require or adhere to a different timing budget than allowed in the PCIe specifications.

In order to turn off Hot-plug/Hot-swap, toggle the top actuator on the Chassis

Alternate Function DIP Switch from its default right position to the left as shown

below:

If you have any doubts, please check with you card’s vendor that no such

constrains exist for this card.

COMPATIBILITY ISSUE

A documented compatibility issue exists between an Apple’s MacBook Pro

and G5 systems in conjunction with the EB7-X8G2-RAS chassis on which is

connected an ATTO Technologies’ UL5D PCIe SCSI adapter. In this

configuration, the Hot Plug feature needs to be disabled, otherwise the system won’t boot.

Finishing Touches

After your system is working properly, replace any empty slots with slot covers, replace the host computer cover, and the close the expansion chassis.

“Hot-Swappable” PCIe Card Installations

New PCI Express technology allows you to remove your 3rd Party PCIe cards for maintenance or replacement – without shutting down the system. The EB7-X8G2-RAS expansions system supports Hot Plugging/Hot Swapping of cards as defined by the PCI express specifications.

By design, this feature allows the host PC to gracefully remove power to a slot, so that a PCIe card can be removed and replaced. It then powers on the new card in coordination with the PC’s operating system. By default, the EB7-X8G2-RAS ships with this feature turned on.

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

Each of the PCIe slots is controlled by a Hotplug (HP) pushbutton. The buttons are enumerated 1-7 as shown below:

Simply press the Attention Pushbutton corresponding to the slot you wish to “power-down.” The power will be removed from that slot within 5 seconds so that the card can be replaced. All other PCIe cards remain.

Hot-Plug/Swap Procedure for Windows

1. Given a stable Windows-based system booted with the Magma chassis, an applet on the right

hand side of the start menu bar should appear depicting a card with a green arrow above it.

Double click on the applet.

2. A dialog should appear with the title “Safely Remove Hardware” in the dialog will be a list of devices that may

be removed from the system. Within this list will be the cards currently plugged into the chassis.

Select a device and click on the “Properties button”.

3. If the device is currently in the Magma chassis, the location will show “Magma chassis x slot y”. Where x

identifies the physical chassis and y identifies the slot the device is plugged into.

After verifying that this is the device to be removed, click on the OK button to close the new dialog.

4. The properties dialog should close and the original “Safely Remove Hardware” dialog should remain.

Click on the Stop button of the dialog.

5. A dialog with the title “Stop a Hardware device” should appear. This is to confirm the stop command that will

be sent to this device.

Click on the OK button of the new dialog.

6. After a brief period a pop up will appear confirming that the device may be removed safely, and the device

will be removed from the list of the original dialog.

In the chassis, press the Attention Button that corresponds to the slot where the device is located.

7. A green LED, labeled PX PwrE (where X corresponds to the slot number) will begin to flash.

Note: If, by mistake, you’ve pressed the button corresponding to the wrong slot, then press it again within 5 seconds and the hot plug request will be ignored. Otherwise continue to step 8.

8. After 5-6 seconds the LED will stop flashing and turn off completely.

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

IMPORTANT

Ideally the PCIe card that was removed from the system will be replaced with an identical, working card. Replacing that card with one that has a different function or purpose may cause the system to crash due to a mismatch in the resources pre-allocated by the operating system.

Remove the card and replace it with a new one. Then press the button again.

1. The LED should start flashing again.

If power should not be applied to this slot, immediately press the button again and the LED will stop flashing and remain off, otherwise go to step 10.

2. After 5-6 seconds the LED will stop flashing and remain on.

After a brief period the new device will be recognized by the system, and it should be added back to the list in the

“Safely Remove Hardware” dialog.

Hot-Plug/Swap Procedure for Linux

1. Set up a console as super user and run: “tail …” to receive messages.

sudo –f /var/log/messages

2. Open another console as super user and run: “modprobe pciehp”

sudo /sbin/modprobe pciehp

3. If there are any error messages in the first console run: “modprobe pciehp pciehp_force=1”

sudo /sbin/modprobe pciehp pciehp_force=1

4. Verify that there are entries in the /sys/bus/pci/slots directory and determine which slot corresponds to the

chassis. The entries shown may not correspond to the slot numbers labeled on the chassis, therefore this verification is required.

cd /sys/bus/pci/slots/

Note:

For SUSE 11, slots may be reported as 1,2,3... For SUSE 10 sp2, slots may be reported as: Segement:Bus:Device:Function.

5. In order to determine whether power is applied to a slot run:

cat <./slot filename>/power

1 – Means the slot is powered; 0 – Means the slot does not have power

6. In order to turn off power to a slot run:

echo 0 > <./slot filename>/power

After the PCIe card has been removed and replaced, turning on the power to the slot is done by running:

echo 1 > <./slot filename>/power

Note: Different Linux versions and platforms may perform differently. Also, older versions, such as Redhat ver. 4 or (2.4.x do not support this feature).

EB7-X8G2 | Chapter 4 Install PCIe Cards

The Alternate Function DIP Switch

The Alternate function DIP switch controls the following three functions: Hot Plug, Clock and power delivery behavior.

Actuator (1) Hot Plug:

Turns the Hot Plug function ON and OFF. Its default position is Enabled in which case a Hot Plug controller supervises power delivery to the PCIe slots.

Actuator (2): Local Clock:

Turns on a local clock generated by the chassis itself independent of that of the Host system. Its default position is Disabled, i.e. the system Clock comes from the Host system (uplink).

Actuator (3): Slot Clock

Should be enabled only when a PCIe CPU card is placed in the 7th slot. That way a locally-generated clock can be supplied to the card.

Actuator (4): For Magma internal use.

EEPROM Loading

The core component in the expansion chassis—the PCIe switch— requires EEPROM loading of code for proper operation in PCIe Gen II mode. Therefore in an EB7x8G2 system, which supports Gen II speeds, J16 must be installed. In case of the EB7x8 system, J16 may remain open.

Magma

EB7-X8G2 | Chapter 4 Install PCIe Cards

EEPROM Write Protect (WP)

J9 is used to enable or disable writing/programming the EEPROM with new code. Since EEPROM programming should be done only by Magma personnel, it is recommended to keep write-protection on.

PCIe Switch I2C Address Setting

SW9 is used to specify a different address for the PCIe switch in its secondary I2C bus. To be used by Magma personnel only.

PCIe Expansion Performance with the EB7-X8G2-RAS

In the following section we will take a look at possible PCI Express expansion solutions using Magma’s EB7 chassis.

High Performance Video Card expansion solutions

Magma’s EB7-X8G2-RAS chassis can be used to add a high end PCI express video card to a system, be it a server, a PC or a laptop that were not equipped with such a device for various reasons: cost, lack of physical space, heat dissipation considerations, etc.

A question then arises as to how good of a performance can we obtain by utilizing the expanded PCIe bus and high end video card vs. the built in video solution. For

that we turn to Futuremark’s 3DMark® benchmarking software which has quickly

become the de-facto standard in Video card performance testing and evaluation.

The 3DMark® suite is optimized to work under Windows XP/Vista/Win7 and supports the latest DirectX and derivative 3D multimedia technologies.

In this environment, a Gigabyte X58-UD5 was tested with various external PCIe video cards connected to Slot #1 (PCIe x8G2) of the EB7-X8G2-RAS.

The motherboard has a Geforce 7600GS graphic card which is used an secondary monitor. We first established a baseline by installing a high performance x16 Gen1 PCIe card into the EB7-X8G2-RAS: The Nvidia 8800 Ultra.

* These tests measured the net GPU performance, not including the CPU

The comparison table above shows an average 54% performance improvement between the baseline and the highestend video card tested. In other words, by expanding the PCI Express bus, the EB7-X8G2-RAS system was able to facilitate an ever-improving benchmark result limited only by the 3rd party card’s performance and the bandwidth limitations of the bus itself.

For more details on the actual test methodology and an explanation of the benchmark figures please refer to:

Magma

EB7-X8G2 | Chapter 5 Chassis Maintenance

Always remember to power down your computer and the expansion system BEFORE you attempt to perform any maintenance tasks.

Do not use a vacuum because vacuums create ESD.

Chapter 5 Chassis Maintenance

Like all computer systems, you will need to perform some routine maintenance tasks. Some of these include making sure that the air vents in the chassis are clear of obstructions and that the cooling air from the fans flows freely. You will also need to check the foam filter behind the front panel to ensure it is clean, thus allowing for unrestricted air flow to the fans. You should always keep an eye on all cables to make sure they are not damaged and are securely connected. Occasionally, you should remove the chassis cover and check for loose cards, and remove any dust build-up.

General Chassis Cleaning

The environment where your Magma chassis is operating should be the determining factor as to how often you should perform a general cleanup of the chassis. To perform a routine general cleaning of your chassis, you will need the following:

1. Can of compressed air (proper distance, 6 inches)

2. Cotton Swabs

3. Isopropyl (alcohol)

4. Anti static wipes

5. Warm water (for filter)

6. Dish soap (for filter)

First, remove the four cover screws and the top chassis cover:

Next, use a can of compressed air from your local computer store to blow out any dust that may have accumulated in the chassis fans.

Be sure to keep the can of compressed air about six inches from the parts being sprayed with air. Pay particular

attention to the fans in the chassis and power supply because they are critical to air movement and to keeping

your chassis cool. Also spray the PCIe slots on the backplane.

Magma

EB7-X8G2 | Chapter 5 Chassis Maintenance

If your chassis is extremely dirty and you would like professional help with getting it clean, you can contact Magma Support for instructions and costs on shipping the chassis back for cleaning.

NOTE

The Magma part number for a replacement fan is: 26-00031-00

Next, you can use anti static wipes to wipe down any open areas inside and outside of the chassis to remove any remaining dust or dirt. If you have dust or dirt remaining in any “hard to reach area”, such as corners of a fan blade, you can use the cotton swabs, dipped in the isopropyl (alcohol), to gently rub the area clean.

Lastly, if the chassis was extremely dirty, you can remove any installed 3rd Party cards and wipe the PCIe slots with a soft bristle brush (like a toothbrush), dipped in the isopropyl (alcohol), to gently clean each slot. When finished, blow the slots with compressed air from about six inches away until dry.

Finally, clean the air filter following the instructions later in this chapter. When finished, replace the cover and turn on power to the system.

Fan replacement

The EB7-x8G2-RAS chassis was designed to allow “hot-swappable” fan replacement while the chassis is powered on. First you will need to remove the chassis’ lid as shown in the beginning of Chapter 4. Then locate the fan that has failed,

unlock its thumbscrew, lift up its metal tab and pull it out.

Insert the new fan in and secure it in place. Verify the new fan is spinning and restore the chassis lid.

Magma

EB7-X8G2 | Chapter 5 Chassis Maintenance

In order to ensure the safety and efficiency of your expansion system, it is recommended that you keep a spare power supply module on hand – just in case. Protect yourself, keep a spare. Order your spare power supply module from Magma –

PN 40-00030-01.

“Hot-Swappable” Power Supply

In spite of regular performance of routine maintenance tasks, some computer systems can experience hardware failures. Fortunately, your investment in a Magma Expansion system with a redundant power supply provides you with the ability to easily replace a power module in the event of a failure.

The redundant power supply includes two hot-swappable modules that share the power load requirements during normal operations. Should one module fail for any reason, the power load will be shifted to the other module and sound an audible alarm.

If a power supply fails, an alarm will sound to alert you of the problem. Press the black button on the status panel on the front of the unit to stop the audible alert.

To replace a failed power supply, simply grab the handle, press down on the release lever at the top of the module, and pull. Replace the failed module with a new one and turn on the power to the module using the power switch at the bottom of the module. The power load will again be shared between these two modules.

Magma

EB7-X8G2 | Chapter 5 Chassis Maintenance

NOTE

Note the different types of screws and where they go as you take them out.

Cleaning the Air Filter

The chassis is equipped with an air filter that is easy to remove and clean. To keep your chassis running at its coolest, you should clean this filter regularly. How often the filter requires cleaning depends on environmental conditions where your Magma Expansion chassis is located. To clean this filter, follow these simple steps.

First, power down the chassis and then remove the screws on the side of the front panel with a Phillips screwdriver.

Next, open the faceplate slowly and disconnect the wire marked below:

Then remove the foam filter, located behind the faceplate, and clean it with a solution of warm water and mild dish soap.

Finally, replace the filter, reconnect the LED panel. Secure faceplate with Phillips screws. Tighten screws until snug and turn on power to the chassis.

Magma

EB7-X8G2 | Chapter 6 Troubleshooting

Chapter 6 Troubleshooting

Before discussing a troubleshooting methodology for locating the problem we will first introduce several indicators and configuration switches that provide general and specific information for this process.

Status Indicators and configuration switches

Under normal operating conditions the status indicators are for internal Magma troubleshooting while the configuration switches/jumpers should remain in their default state preset by Magma for best compatibility. However, should a problem occur with the chassis (or a special mode of operation be solicited by the client) we included below explanations as to what all these items are and how they should be treated:

Status Panel indicators

All LED’s should be green at all times. An orange LED means a fault of the corresponding item listed in the picture above.

Chassis Signal Detect Indicators

This group of LEDs (D2, D6-D8) indicates the existence of PCIe traffic on the receiver side on the respective PCIe lanes. In the example shown here, an active x8 link is identified by x1, x2, x4, and x8 LEDs being ON. During normal operation signal detect LEDs and D14 (clock good) should be ON with the exception of D9 whose role is to indicate loss of signal and logic failure.

Magma

EB7-X8G2 | Chapter 6 Troubleshooting

Chassis Slot Power Indicators

If the unit is in Hot-Plug mode (default factory setting) then the orange Power Off LEDs found between the slots and chassis will be lit. They indicate lack of power at the respective PCIe slot. This would be a normal condition if the chassis is powered on while the Host system is turned off (RESET state) or if power to a specific slot has been removed for it to be swapped as part of the Hot-Plug procedure.

If the Host system is turned ON but there is no PCIe card in the slot, the Power Off LED will be ON.

If the unit is NOT in Hot-Plug mode, the orange LED’s should be all off.

If a slot has a card in it and the respective orange LED turns on that means there was a power fault in that slot. If that is the case, one needs to follow appropriate procedure to power down the host and then power down the chassis. If the problem persists, check with the card manufacturer if it requires more than 8 Amps of current at any time. Otherwise contact Magma Technical support.

Chassis Linkup and Activity Indicators:

These indicators were purposely made visible at the back of the chassis in order to allow a quick verification of connectivity between Host and chassis.

Magma

EB7-X8G2 | Chapter 6 Troubleshooting

Each of the LEDs shown above indicates the connectivity status of the PCIe card inserted into the respective PCIe slot. Once connectivity has been established between the host computer and one (or more) PCIe cards, the respective LED(s) will light up. The Uplink Port LED will light up as soon as the chassis had linked with the host system regardless of how many PCIe cards are installed in the chassis, or if none at all. Therefore in normal working conditions it should always be lit.

The activity LEDs will blink occasionally whenever the host is communicating with the card is a respective slot.

SNMP Power-On Source Jumper

The SNMP module inside the EB7-X8G2-RAS chassis features a power-on source jumper to select between local power-on (via the master on/off switch) and remote turn-on (via the SNMP software/front end).

In order to gain access to this module (and respective jumper), the top cover of the chassis needs to be removed. Dismount the chassis from the rack (if applicable) and carefully remove the screws holding the chassis cover in place. The SNMP module will be located on the right side of the unit oriented with the fans facing us.

Magma

EB7-X8G2 | Chapter 6 Troubleshooting

Now locate the J6 jumper as shown below

Locating the Problem

If you are having trouble with the Magma expansion system, first verify that all cards and cables are seated properly. Be sure you followed the instructions in earlier sections of this Service Manual. Always remember to power On and Off correctly when rechecking your installation. If you are still having problems, try these troubleshooting steps:

 My Computer Can’t Find the PCIe Expansion System  When Nothing Works  My PCIe Card Doesn’t Work  My system hangs beyond a certain number of add-in cards

The Magma PCIe Expansion System is correctly displayed as a “PCI standard PCI-to-PCI bridge” in Windows Device Manager and as a “pci-bridge” in the MAC Apple System Profiler and in Linux. When connected and functioning correctly, this Expansion System will be displayed as follows:

If this is not what you see when you verify your installation, the following troubleshooting steps may help you locate and resolve your installation issues without having to call Technical Support.

My Computer Can’t Find the PCIe Expansion System

If the expansion system is not visible in your Windows Device Manager or your Apple System Profiler at all, you will need to turn off your computer (first) and then the Magma expansion chassis (second) and test all cords and cables to ensure you have everything connected correctly. If everything seems to be connected correctly, and you are sure you have applied power correctly (power up the expansion chassis first and then the computer), then try the following troubleshooting steps:

 Verify that the required LEDs on the back of the chassis are lit as explained in the Chassis Linkup section above.

The most important indicators are the LINK LEDs that indicate a proper connection. All LINK LEDs on the host and expansion cards should be ON if both PCIe slots are populated and both an uplink and a downlink iPass cable are connected properly. The ACT (activity) LEDs will light/blink only upon data transfers between host and expansion. They can be off so long as the required LINK LEDs remain on.

 Also verify the Magma PCI Express Host card is properly inserted into the host computer slot. In case any other LED

is off, ensure the respective card is functional and properly seated in its ExpressBox slot.

 Try moving the PCIe host card to a different PCIe slot.  If the expansion system is still not visible after trying all of the above steps, go to Chapter 7 to get additional help.

My Computer Hangs During Power Up

If your computer “hangs” while being turned on and you can’t even start, follow the following steps to try to fix this problem:

1. Shut off the computer (first) and then the Magma expansion system and verify that all cards and cables are

connected and seated correctly.

2. If it still hangs and you have added one or more hard drives in addition to several PCIe cards, ensure that you

have not exceeded the power capabilities of the expansion system‘s power supply. You can verify the

capacity of your power supply by checking the label on the power supply. If you are not certain about the power consumption of your peripherals, it is best to remove them one by one (starting with those you suspect of being most “power hungry”) until the system powers up.

3. If you have removed all 3P a. Remove the Magma PCIe expansion host card from the computer and try booting up without the Magma

expansion system attached.

i. If it boots up OK without the Magma expansion system attached, call Magma Technical Support.

ii. If it still hangs, the problem is in the computer and not with the Magma expansion system or the 3

Party PCIe cards.

b. If it boots up OK without any 3

i. If it boots up OK with one card in it, shut it down and swap cards. Repeat this until all cards have been

tested. If they all test OK, then add them back one at a time until you find the combination that doesn’t work. If you find a bad card, call Technical Support. If you don’t – congratulations, you fixed it!

Party PCIe cards from the Magma chassis and it still hangs, try the following:

Party PCIe cards installed, try adding only one card and see if it boots up.

ii. If it still hangs up, try a different card – this one is probably bad (or has driver problems). If the second

cards works, troubleshoot the first card. If the second card also fails, call Technical Support.

1. Shut down the computer followed by the Magma expansion chassis

2. Remove the PCIe card displaying a problem

3. Replace the “problem card” with a simple PCIe card, such as an Ethernet card that has drivers built into the operating system. (Using this “type of card” will avoid any future questions about drivers possibly being installed incorrectly.)

4. Turn on the Magma expansion chassis, and then turn on the computer.

My system hangs beyond a certain number of add-in cards

Any PCI or PCI Express expansion scheme requires the cooperation of the computer system’s BIOS in order to operate

properly, regardless of the platform (PC/Laptop/Server) or operating system (MS Windows/MAC OS/LINUX etc.)

The BIOS hosts the first and the most fundamental code (firmware) that a computer executes upon boot-up. It is then that each and every PCI/PCIe add-in card (be it located on the host system or on Magma’s expansions chassis) is allocated Input/output memory space for proper operation.

By installing multiple add-in cards in one chassis or chaining multiple Magma chasses (as discussed in: Appendix A), we’re requesting more and more resources from the BIOS and thus must make sure we pre-allocate them sufficiently.

It is therefore imperative that our computing platform allocates at least 32KB of I/O memory space to allow multiple add

in cards to operate properly. This setting may be editable or preset by your BIOS (or computer) vendor. If you’re having

this problem it is recommended that you first update your system to the latest firmware provided by your vendor. Instruction on how to do that (as well as making a backup of your current BIOS firmware) should be provided by your computer vendor on their web site.

In case this property is editable, you computer vendor should also be able to tell you how to select at least 32KB using their BIOS interface.

Rackmounting the Chassis

Locate a vacant 4U slot in your rack that is within the reach of the one-meter cable that came with your EB7-X8G2-RAS Expansion System. Install the rails in the rack as shown below:

Measure the rack from front to back so you can confirm how long the rail must be to fit properly.

Next, assemble the Slide piece with the end bracket as shown and secure with 2 Panhead screws and locking nut. Ensure the Phillips screw head is located on the “open” side of the Slide pieces as shown.

Tighten finger tight only to allow for minor adjustment during assembly.Depending on the depth of your rack you may select either the long or the short end bracket.

Magma

EB7-X8G2 | Chapter 6 Troubleshooting

NOTE

Notice that the holes on the Bar Nut are spaced unevenly to accommodate different racks.

Add Screws to Rack Post

Attach 2 Panhead screws into the rack post where you want the chassis mounted. Be sure you have measured accurately to ensure that everything fits in the rack correctly. Leave the screws untightened until after you place the slide rail’s fingers between the screws as shown.

If your rack has holes too large for the screws, you can use the Bar Nut to secure your mounting by inserting the Panhead screw through the rack hole and screwing it into the Bar Nut on the reverse side of the rack post, as shown.

Attach Slide Rail to Rack

Attach to inside of rack with “fingers” pointing “out” and the end bracket

to the rear. Secure each Slide Mount with 4 screws as shown below.

Secure the slide rail to the rack with 2 screws to both front and rear posts. After you have secured the slide rail fingers to the rack posts, tighten the 2 screws used to attach the slide rail to the end bracket.

Attach Chassis to Slide Rail

The chassis mounts into the rack from the front. Insert the chassis into the rack slide and press it forward until the chassis stops. When the chassis is completely inserted into the rack, secure the mounting brackets 2 screws on each side.

EB7-X8G2 | Appendix A Need More PCIe Slots?

In theory, your computer “should” be able to travel across up to 255 PCIe buses to identify

and configure all installed PCIe cards. The 255 PCI bus limit is actually a theoretical maximum. The practical limit is somewhat lower and differs from one system to another, but should still be a fairly large number.

In a desktop computer the bus numbers tend to be lower (0, 1, 2, etc.). Once the BIOS is finished configuring everything and assigning resources, the Operating System starts loading and activates the PCIe cards found.

When adding more Expansion Systems to an existing system, be sure to connect and test them “one-at-a-time.” This will allow you to quickly resolve any connectivity, or other, issues right at the start. DO NOT INSTALL any 3rd Party PCIe cards into any system until ALL attached systems are working correctly.

Appendix A Need More PCIe Slots?

Multiple PCIe Expansion System Configurations

The PCI Express Local Bus Specification defines the bus as hierarchical, where logical PCI to PCI Bridges (PPBs) may be used to add "levels" to the PCI bus hierarchy within a PCIe switch. Because hierarchies are organized systems arranged into different levels, you can take advantage of this automatic organizing and layering to expand the number of available PCIe slots beyond the number available in your computer’s motherboard.

You can easily add two or more Magma expansion systems to your current system in a "fan-out" configuration. Each of these configurations has advantages and uses. To determine which type of configuration you wish to use, you should first understand a few basic facts:

1. In a desktop computer, the BIOS enumerates automatically behind logical PCI bridges. In the Magma configuration, the BIOS looks beyond the Host card to find any PCIe cards installed in the expansion chassis behind a PCIe switch. The PCIe switch, in turn, emulates logical PRBs. The BIOS can then configure the cards and allocate resources. Empty PCIe slots are ignored during configuration.

2. Most computers allow multiple logical bridges (and thus PCIe buses) to be correctly configured. Some computers, unfortunately, place an arbitrary limit on the number of bridge levels that can be traveled during power-on configuration. Your computer “power-on-software” should be compliant with the PCIe bus specification in order to effectively use a Magma PCIe Expansion System. For a "fan-out" system configuration, where more than one PCIe expansion system is being used, you should count all of the logical bridge levels to your most deeply nested PCI bus to determine the maximum number of bridge levels that must be traveled. Exceeding this number may cause software configuration conflicts even though hardware-wise the PCIe system is properly configured.

3. For easier understanding, a given PCI system should be viewed as a “Resource Toll road” that runs from the

computer CPU (resource home), through the “Toll Booths” (the PCIe switches and logical PCI bridges), to the “Resource Users” (PCIe Cards). As in the case of a real Toll Road, the more Toll Booths you have to cross (even if

it takes a nanosecond), the longer it will take you (your data) to get from the PCIe Card to the CPU and back again. Under most circumstances the effect cannot even be detected. However, under other conditions, it can be important to know about.

Magma

EB7-X8G2 | Appendix A Need More PCIe Slots?

You must ensure that you have the corresponding PCIe to PCIe Expansion System, or chassis to connect with your host card to support your desired configuration.

For clarification, it is necessary to understand that the amount of latency caused by a PCIe switch (or a PCIe-to-PCI bridge built into some 3rd Party PCIe cards) is negligible

(“nanoseconds”) and will not produce any visible effect on most systems. It is only mentioned

here because of certain specialized configurations involving unique PCIe cards with special software drivers. The total number of logical buses that the data must pass through COULD make a difference. See Chapter 5 Troubleshooting for more information if you suspect this could be an issue with one of your specialty PCIe cards.

The Fan-Out Configuration

The Fan Out addition to the PCI bus hierarchy is at the "peer" level of other existing expansion buses, thus adding "breadth" to the PCI bus hierarchy, since these buses will be at the same hierarchical level within the system configuration.

In this configuration, you have fewer “Toll Booths” to pass through; therefore the latency is shorter, however you “sacrifice” a PCIe slot in the host computer for each added chassis.

Verify your configuration

Before you start installing your PCIe cards (refer to Chapter 4 Install PCIe Cards for more information), you should confirm that everything is in proper working order. Refer to Chapter 3 Verify Installation for guidance in verifying the proper installation of your Expansion System. For example, the following image shows the division within the Windows Device Manager display between two Expansion Systems connected in a “Fan-Out” configuration. In this case each expansion chassis offers only two slots of expansion.

Magma

EB7-X8G2 | Appendix A Need More PCIe Slots?

The following image shows the Apple Profiler display when a MAC has 2 Expansion Systems connected in a “Fan-Out” configuration.

Daisy-Chaining

This configuration offers multiple expansion slots by “sacrificing” only a single slot on the host computer. However, in this scenario we must also dedicate one of the slots in the expansion chassis for Daisy-Chaining another chassis below it (a.k.a Downlink). For optimal downlink performance, it is best to dedicate the chassis’ x8 slot for daisy-chaining.

In the daisy-chain configuration, successive PCIe expansion systems are added to the "end" of the PCIe expansion hierarchy, which adds "depth" to the Local Bus by increasing the number of the logical PCI levels active in the system configuration.

The daisy-chain configuration is therefore more popular among those who have only one available PCIe slot on the host computer, but require additional slots downlink keeping in mind that more latency will be introduced every time we go from one expansion chassis to the other.

Verify your configuration

Magma

EB7-X8G2 | Appendix A Need More PCIe Slots?

NOTE

Notice that each Daisy-Chained unit appears in the Device Manager in the reverse order of its place in the configuration.

PCI e Card Conflicts

If you determine that one PCIe card is interfering with the operation of another card, first try reorganizing the cards on the motherboard. Moving the cards around can change the order in which the cards are configured by the system during power-on. This will go a long way toward resolving module conflicts.

Power-On Sequence for Advanced Configurations

As previously stated in Chapter 2 Hardware Installation, it remains necessary to power up ALL Expansions Systems BEFORE you turn on the computer. This will ensure that your power-on software can read all available buses and properly configure all installed PCIe cards.

Obviously, the reverse also remains true for shutting your system down. The computer must be shut off BEFORE you attempt to turn off your Expansion System(s).

Troubleshooting Advanced Configurations

When trying to troubleshoot problems with PCIe cards in a multiple expansion system configurations, it is vital to correctly determine the nature of the problem. Therefore, the first task is to identify the card or chassis having a problem by using the Windows Device Manager, or Apple System Profiler. Refer to the first part of this Appendix for more information on identifying hierarchical levels in multiple expansion system configurations.

Problems with 3rd Party PCIe cards might only be traceable once you have identified the expansion system containing the problem card.

Below is a flow chart offering a troubleshooting approach when multiple expansion chasses are involved:

Finding the Problem Card

Windows

If you need help to determine which PCIe card, or which expansion chassis, has the problem, you can “right-click” on

the card with the and check the information contained in the “Location:” field

Magma

Look for the “Error Code” in the box in the center of the Properties Window and then go to the Windows Error Code section for information on how to resolve this issue.

MAC and Linux

If you have already reinstalled and reseated everything according to instructions in Chapter 2, and the PCI to PCI Bridge is still not visible in the Apple System Profiler, call Magma Technical Support.

EB7-X8G2 | APPENDIX B I/O Switching Via SNMP

APPENDIX B I/O Switching Via SNMP

The following instructions involve configuring 2 servers that are exactly identical to be able to switch I/Os at any given time. The switch I/O feature can be used as a failover mechanism if one server went down or if the I/Os need to be designated to Server 2 for any reason. It should be noted that this feature is not yet applicable to cases where the two host machines are not identical (i.e. taking the I/Os of a serial card away from and IBM server and re-designating them to a Dell server).

Further, Server 1 and Server 2 must share the same processors, chipsets and overall architecture, for example, two IBM Blade servers.

In the next example we will use the EB7-x8G2RAS chassis with Magma’s fiber EIF card, 01-04978-05, connected to two IBM servers. Similarly, the EB7-x8G2RAS chassis can accommodate two regular EIF cards in slots 0 and 1, each connected via an iPass cable to the two servers. Finally, this test was performed under VMware ESX4.1.

Step 1: Make sure all systems are off – after doing so, connect both servers to the uplink EIF card in the Magma chassis. Do not turn the servers on just yet. The dual uplink is labeled Server 1 and Server 2, which correspond to the specified fiber ports, as shown below.

 Make sure the chassis is off  Insert and secure the I/O cards in slots 1 through 7 of the chassis

Step 2: Power on the Magma chassis.

BY DEFAULT, ALL I/O ARE ASSIGNED TO SERVER 1

In this example, we will refer to server 2 as the backup server, and server 1 as the main (primary) server.

Step 3: Hook the chassis up to some type of NAT with an addressing scheme of 192.168.X.X so you can access and or change the networking properties

Step 4: Power on server 1 and boot it into the WMware ESX4.1 shell.

Once WMware ESX 4.1 is booted, connect to Server 1 via VSphere and mark our target PCIe device for pass-through as 08:00.0 and 08.00.1. This device is a PCIe card plugged into the Magma chassis, whose I/Os we wish to re-direct, in this case an Oxford Semiconductor serial card.

Magma

EB7-X8G2 | APPENDIX B I/O Switching Via SNMP

After rebooting add the pass-through device to the guest OS of server 1, provide the drivers and install the PCI device.

Step 5: In preparation for switching the I/Os over to Server 2, uninstall the PCI device from the Device Manager of Server

1. Next, open the web UI for the chassis (set to 192.168.1.10) and your browser will show the SNMP web interface for the chassis. Navigate to the tab labeled “I/O Failover” and you will find the default I/O configuration:

In the next image note the status of the two servers indicating which physical fiber link currently has all the I/Os:

Magma

EB7-X8G2 | APPENDIX B I/O Switching Via SNMP

Step 6: Switch all I/Os to server 2, the secondary server, by clicking the button “Switch All I/O Ports >>” in the web interface. You will be directed to a temporary waiting page that looks like this:

After 10 seconds or so, the page will automatically change back to the I/O Failover tab, where you should be able to note that the I/Os have been switched to Server 2:

The image below shows the statuses after the switchover:

Magma

EB7-X8G2 | APPENDIX B I/O Switching Via SNMP

Step 7: Now that your secondary server is ready to handle the transferred I/Os, you can now boot it up into VMware ESX

4.1. After FULLY BOOTING up server 2, connect to Server 1 via VSphere and set up a pass-through on server 2:

Since both server 1 and 2 are hardware-identical, our PCIe device remains at 08:00.0 and 08:00.1. Reboot server 2 and add the PCIe device to the guest OS:

Magma

EB7-X8G2 | APPENDIX B I/O Switching Via SNMP

Now make sure on your server 2 that the drivers for the PCIe device are successfully installed and that it is visible in the Device Manager.

At this point both servers have interfaced with the PCIe device, so that its respective I/Os can be switched back and forth between them. Before switching the I/Os back to the primary server, be sure to terminate any applications that generate I/O traffic.

Step 8: Open up the SNMP web UI once again and switch the I/O back over to Server 1. Be sure to leave the backup server on while doing this. Once you switch I/O back to server 1, your new I/O Failover page will resemble the initial one in the beginning of the process:

Step 9: You are now ready to boot up the primary server (server 1). Once you fully boot up your primary server, you can access all the I/O allocated to it. If you so desire, you can switch the I/Os back over to the secondary server with the ease of a button without having to reconfigure any of the two servers to handle those I/Os
