Working with Mac OS X Lion Server

As soon as you set up your Mac Pro, it's ready to host all of the services provided by Mac OS X Lion Server. You can use Server Assistant to set up your server and migrate information from another Mac server. For information about using your Mac server or using Lion Server, open the Server application and choose Server Help in the Help menu. To learn more about Mac OS X Lion Server software, see the Lion Server website at www.apple.com/macosx/server.

Setting Up Your Mac Pro

Your Mac Pro is designed so that you can set it up quickly and start using it right away. Follow the steps on the next few pages to get started.

Step 1: Position your Mac Pro.

Pick up your Mac Pro by both of its handles using correct lifting techniques. Position your Mac Pro so that:

It is on a sturdy, flat surface
- The power cable connectors don't press against a wall or other object
- The airflow in front of, behind, and below your Mac Pro is not obstructed
- The computer's optical drive trays have space to open in front

The only way to shut off power completely to your Mac Pro is to disconnect the power plugs from the power source. Make sure the power cord for your Mac Pro is within easy reach so that you can unplug it.

Step 2: Plug in the power cord.

Plug the power cord completely into the recessed power cord socket on the back of your Mac Pro and plug the other end into a grounded power outlet.

Step 3: Connect a display.

If you are connecting a display to your Mac Pro, connect it as shown below. Depending on the display, you may have one or more cables to connect. Check the instructions that came with the display for additional setup information.

You can connect up to three displays with Mini DisplayPort or Digital Visual Interface (DVI) connectors to the display ports on the back of your Mac Pro. The DVI display port is a dual-link port, so you can connect a 30-inch Apple Cinema HD Display.

You can also connect displays that have an Apple Display Connector (ADC) or a video graphics array (VGA) connector using one of the following adapters:

• To connect a VGA display to the DVI display port or a Mini DisplayPort, use the Apple DVI to VGA Display Adapter or the Apple Mini DisplayPort to VGA Adapter (both available separately).
• To connect an ADC display to the DVI display port, use an Apple DVI to ADC Display Adapter (available separately).

The Mini DisplayPort outputs provide both video and audio output. You must use the Sound panel in System Preferences to select the connected device for audio output. For more information about connecting an HDMI device, search for "HDMI" on the Mac Pro Support page at www.apple.com/support/macpro.

Display adapters and other accessories for your Mac Pro are sold separately at www.apple.com/store.

Step 4: Connect an Ethernet cable.

To access the Internet or a network using an Ethernet cable, connect one end of an Ethernet cable to either of the Gigabit Ethernet ports on the back of your Mac Pro. Connect the other end to a cable modem, DSL modem, or Ethernet network.

Step 5: Connect a keyboard and mouse.

If you are connecting a USB keyboard and mouse, connect the USB cables to the USB ports () on your Mac Pro or on a display.

Note: You can set Mac OS X Lion Server up remotely from another computer. For information, open the Server application on the other computer and choose Server Help from the Help menu.

Step 6: Turn on your Mac Pro.

Press the power button (U) on the front of your Mac Pro to turn it on. If you have a display that must be turned on separately, turn it on by pressing its power button. If you connected a mouse, click your mouse to establish a connection with your Mac Pro.

Step 7: Configure your Mac Pro server with Server Assistant.

The first time you turn on your Mac Pro with Mac OS X Lion Server installed, Server Assistant asks for some basic information that Lion Server needs in order to start up and connect to the network. Be ready to provide the following information the first time you turn on your Mac Pro:

• An account name and password.
• An organizational name that's unique in your company.
• A host name, which can be for your local network only, for your local network and VPN access from the Internet, or an Internet host name you purchased from a domain name registrar.
• Detailed network settings, including IP address, subnet mask, and DNS servers. The network settings may be provided by your Internet router or a server on your network. If so, it should be configured to provide your server the same IP address all the time (static mapping or DHCP reservation).

For help with Server Assistant, click the Help button in any pane.

You can set up Mac OS X Lion Server remotely from another computer. For information, open the Server application on the other computer and choose Server Help from the Help menu.

Adding PCI Express Cards

You can expand the capabilities of your Mac Pro by installing cards in the Peripheral Component Interconnect (PCI) Express slots. Your Mac Pro has one double-wide PCI Express graphics slot and three PCI Express expansion slots, for a total of four slots. These slots accommodate PCI Express graphics cards and expansion cards.

About PCI Express Cards

Your Mac Pro comes with a high-performance PCI Express graphics card, which contains the graphics processing unit (GPU) and provides the computer's display ports. The graphics card is installed in slot 1.

You can install additional PCI Express graphics and expansion cards. Before installing a card, check its specifications to make sure it can operate in your Mac Pro:

• Slots 1 and 2 are x16, PCI Express 2.0 slots
• Slots 3 and 4 are x4, PCI Express 2.0 slots

All four slots support 16-lane cards.

NOTICE: Combined maximum power consumption for all four PCI Express slots must not exceed 300 watts (W).

To install a PCI Express card:

1 Open your Mac Pro and remove the side panel, following the instructions in "Opening Your Mac Pro" on page 33.

WARNING: To avoid damaging internal components or the components you want to install, always turn off and then unplug your Mac Pro. Do not attempt to install items while it is plugged in. Let your Mac Pro cool down for 5 to 10 minutes before you touch the internal components, which may be very hot.

2 Unscrew the captive screws in the PCI bracket and remove the bracket.

3 Remove the port access cover from the slot in which you plan to install the card.

4 Press the button on the PCI slider and move the slider to the left, which moves the retention bar.

5 Remove your new card from its static-proof bag and hold it by its corners. Don't touch the gold connector or the components on the card.

If You're Installing a Full-Length PCI Card

It may be easier to install a PCI card if you remove the hard disk drives and carriers (see page 56), and remove adjacent cards. Make sure the end of the card goes in the appropriate card guide before aligning the card with the PCI slot and completing the installation.

6 Align the card's connector with the expansion slot and press the card into the slot.

7 Press the card gently but firmly until the connector is fully inserted. Press only on the bare areas of the card to avoid damaging the components. Don't rock the card from side to side or force it. If you meet resistance, check the connector and slot for damage or obstructions, and then try inserting the card again.

Problem, Meet Solution

Occasionally you may have problems while working with your Mac Pro. Read on for troubleshooting tips to try when you have a problem. You can also find more troubleshooting information in Help Center or on the Mac Pro Support website at www.apple.com/support/macpro.

When you experience a problem with your Mac Pro, there's usually a simple and quick solution. Think about the conditions that led up to the problem. Making a note of things you did before the problem occurred will help you narrow down the possible causes of the problem and find the answers you need. Things to note include:

• Any software that you recently installed.
• Any new hardware (such as memory, graphics or PCI Express cards, hard disk drives) that you installed or peripherals that you connected.

An Ounce of Prevention

If you have a problem with your computer or software, having kept up-to-date Time Machine backups ensures that your data won't be lost. If you make regular Time Machine backups, you can restore your software and all your data to exactly the way it was at the time of the backup. Even serious issues are of less concern when you safeguard your information with Time Machine.

For important information about backing up your server data, see the Lion Server website at www.apple.com/macosx/server.

If Network Diagnostics can't resolve the problem, there may be a problem with the Internet service provider (ISP) you are trying to connect to, with an external device you are using to connect to your ISP, or with the server you are trying to access. You can also try the steps in the following section.

Cable Modem, DSL, and LAN Internet Connections

Make sure all modem cables are fully plugged in, including the modem power cord, the cable from the modem to the computer, and the cable from the modem to the wall jack. Check the cables and power supplies for Ethernet hubs and routers.

Turn off your DSL or cable modem for a few minutes, and then turn it back on. Some ISPs recommend that you unplug the modem's power cord. If your modem has a reset button, you can press it either before or after you turn the power off and on.

PPPoE Connections

To enter PPPoE settings:

1 Choose Apple () > System Preferences.
2 Click Network.
3 Click Add (+) at the bottom of the network connection services list, and choose PPPoE from the Interface pop-up menu.
4 Choose an interface for the PPPoE service from the Ethernet pop-up menu.

Choose Ethernet if you are connecting to a wired network, or Wi-Fi if you are connecting to a wireless network.

5 Click Create.
6 Enter the information you received from your service provider, such as the account name, password, and PPPoE service name (if your service provider requires it).
7 Click Apply to make the settings active.

Network Connections

Make sure the Ethernet cable is plugged into your computer and into the network. Check the cables and power supplies to your Ethernet hubs and routers.

If you have two or more computers sharing an Internet connection, make sure your network is set up properly. You need to know if your ISP provides only one IP address or if it provides multiple IP addresses, one for each computer.

If only one IP address is used, then you must have a router capable of sharing the connection, also known as network address translation (NAT) or "IP masquerading." For setup information, check the documentation provided with your router or ask the person who set up your network. You can use an AirPort base station to share one IP address among multiple computers.

For information about using an AirPort base station, search for "AirPort" in the Help Center or see the AirPort support website at www.apple.com/support/airport.

If you cannot resolve the issue using these steps, contact your ISP or network administrator.

Maximizing Ethernet Performance

Your computer performs best when the Ethernet port to which it is connected is set to autonegotiate. Ask your network administrator to verify this setting.

Note: If you experience connection problems on your network, make sure your network switch is set to autonegotiate, if possible. If a switch's port is not autonegotiating, your computer detects the appropriate speed but defaults to half-duplex mode. If the switch's port at the other end of the link is configured for full-duplex mode, a large number of late events can occur on the link. If it isn't possible to set the switch to autonegotiate, then set the switch's port to half-duplex. For more information, see the documentation that came with the Ethernet switch.

Keeping Your Software Up to Date

You can connect to the Internet and automatically download and install the latest free software versions, drivers, and other enhancements from Apple.

When you are connected to the Internet, Software Update checks to see if any updates are available for your computer. You can set your Mac Pro to check for updates periodically, and then you can download and install updated software.

To check for updated software:

1 Choose Apple (串)> Software Update.
2 Follow the onscreen instructions.

• For more information, search for "Software Update" in Help Center.
• For the latest information about Mac OS X Lion Server, go to the Lion Server website at www.apple.com/macosx/server.
• For the latest information about Mac OS X, go to www.apple.com/macosx.

Last, but Not Least

This chapter provides important information about safety procedures, routine maintenance, and ergonomic considerations for using your Mac Pro and display.

For your safety and that of your equipment, follow these rules for handling and cleaning your Mac Pro and for working more comfortably. Keep these instructions handy for reference by you and others.

NOTICE: Incorrect storage or use of your computer may void the manufacturer's warranty.

Important Safety Information

WARNING: Failure to follow these safety instructions could result in fire, electric shock, or other injury or damage.

The only way to disconnect power completely from your Mac Pro is to unplug the power cord from the main power supply. To disconnect a display completely, you must also unplug its power cable from the computer or power outlet. Make sure that at least one end of the device's power cord is within easy reach so that you can unplug the computer or display when necessary.

Always take the following precautions.

Disconnect the power plug (by pulling the plug, not the cord), from your computer or display and disconnect the phone cord if any of the following conditions exist:

• The power cord or plug becomes frayed or otherwise damaged

• You spill something into the case

• Your computer is exposed to rain or any other excess moisture

• Your computer has been dropped or the case has been otherwise damaged
• You suspect that your computer needs service or repair
• You want to clean the computer or the case

If you plan to store your computer for an extended period of time, remove the battery.

For service or questions about your warranty, contact an Apple Authorized Service Provider or Apple. See "Learning More, Service, and Support" on page 93.

General Maintenance

If you need to clean the computer by doing more than wiping it down with a clean cloth, follow these instructions:

1 Turn off your computer and display, if a display is connected.
2 Disconnect the computer power cable from the electrical outlet or power strip. If your display is connected to an outlet, disconnect it as well.
3 Disconnect the display's cables from the computer.
4 Wipe the computer case surfaces lightly with a clean, soft cloth dampened with water.

NOTICE: Don't use alcohol, aerosol sprays, solvents, or abrasives that might damage the finish on the case.

Protecting Your Optical Drive

To keep your optical drive working properly:

• Position your computer so that the drive tray doesn't bump into anything when it opens.
• Close the drive when you're not using it.
• Do not put anything on the drive tray when it is open.
• Do not touch the optical drive lens with your fingers. Do not wipe the lens with a paper towel or other abrasive surface. If you need to clean the lens, see an Apple Authorized Service Provider for a lens cleaner.
• Keep your computer away from any source of moisture.

Laser Information for Optical Disc Drive

For your safety, have the optical drive serviced only by an Apple Authorized Service Provider.

WARNING: Making adjustments or performing procedures other than those specified in your equipment's manual may result in hazardous radiation exposure. The optical disc drive in your computer contains a laser that is safe in normal use but that may be harmful to your eyes if disassembled.

Understanding Ergonomics

Here are some tips for setting up a healthy work environment.

Keyboard

When you use the keyboard, your shoulders should be relaxed. Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

Change hand positions often to avoid fatigue. Some computer users might develop discomfort in their hands, wrists, or arms after intensive work without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.

Mouse

Position the mouse at the same height as the keyboard and within a comfortable reach.

Chair

An adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so your thighs are horizontal and your feet are flat on the floor. The back of the chair should support your lower back (lumbar region). Follow the manufacturer's instructions for adjusting the backrest to fit your body properly.

You might have to raise your chair so that your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you can lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that's lower than the regular work surface.

Display

Arrange the display so that the top of the screen is slightly below eye level when you're sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm).

Position the display to minimize glare and reflections on the screen from overhead lights and nearby windows. If possible, use a tiltable display stand. The stand lets you set the display at the best angle for viewing, helping to reduce or eliminate glare from lighting sources you can't move.

Avoid Hearing Damage

WARNING: Permanent hearing loss may occur if earbuds or headphones are used at high volume. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muffled speech, then stop listening and have your hearing checked. The louder the volume, the less time required before your hearing can be affected. Hearing experts suggest that to protect your hearing:

• Limit the amount of time you use earbuds or headphones at high volume
• Avoid turning up the volume to block out noisy surroundings
• Turn the volume down if you can't hear people speaking to you
