This is a safety feature. If you are unable to insert the plug into the outlet because the outlet is not grounded, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug! Because you are installing the server in a rack with other equipment, be certain that the power outlet and any other equipment, such as a power strip, used with the rack is designed to carry the electrical load of multiple devices. Check the documentation for your rack for any special instructions. For details on disconnecting cables from the server’s back panel, see “Disconnecting Cables From the Server’s Back Panel” on page 55. With the server in the rack and the cables in place, you can prepare to set up the Mac OS X Server software. Attach the Cable-Management Arm to the Support Brace If the rear posts of your rack are more than an inch away from the server’s back panel, you need to attach the cable-management arm to the support brace at the left side of the server (not to the rear post). Otherwise the arm will not extend properly when you open the server in the rack. Chapter 3 Installing Your Server in a Rack If the rear posts of your rack are flush with the server’s back panel or within an inch of it, see “Attach the Cable-Management Arm to the Rack” on page 39 for mounting instructions. Follow these steps to attach the arm to the left support brace. 1 At the front of the server, loosen the thumbscrews securing it to the rack and slide the server a few inches forward. Moving the server forward allows you to check the position of the cable-management arm after you mount it. 2 Use a very small Phillips screwdriver to disconnect the small clamp that wraps around the long end of the cable-management arm (next to the two oval holes). You’ll use this clamp and screw to attach the arm to the brace. 3 Hold the cable-management arm with the long part closer to you and fold the hinged section of the long part away from you. The hinged section is the part from which you removed the clamp and screw. This section should be perpendicular to the main part of the arm, with the oval holes farthest from you. 4 Position the cable-management arm so that the hinged section is on the inside of the left brace, about 2 inches behind the server’s back panel. Mount the cable-management arm as close to the back of the server as possible. Rotate the mounting plate on the arm so that it lies against the inside of the U-shaped bracket. The U-shaped bracket should be sandwiched between the arm and the small clamp. Secure the clamp with the screw that held it stored on the arm. Clamp Screw Cable-management arm U-shaped bracket 5 Hold the arm in place and put the clamp you detached on the opposite side of the arm, so that the screw hole in the center shows through the open part of the brace. 6 Insert the screw into its hole and tighten it so that the arm is fastened to the brace. Chapter 3 Installing Your Server in a Rack 7 Verify that the arm’s position is correct by moving the arm inward so that it swings under the cover of the server. If the arm hits the cover or is not level as you move it, you need to adjust its position by unscrewing one or both mounting screws and moving the arm up or down slightly until it is level and moves smoothly under the server’s cover. 8 Connect the cables to the back panel of the server.

See “Connect Cables Directly to the Server” on page 54 for more information about connecting cables. Chapter 3 Installing Your Server in a Rack 9 Connect the power cord and its retaining clip to the back of the server. If more than one power cord came with your server, use the appropriate cord for the electrical service available at your location. Important: The short power cord provided with some systems is intended for use in a rack that has its own power source. Do not use this cord for any other purpose. Note: You may need to bend the cord near its plug to fit it into the server. Bending the cord will not affect its operation. Attach the power cord retainer clip to the two loops on the back of the server. Snap the cord into the clip so that it cradles the cord. 10 Connect the other end of the cables to the appropriate devices. 11 Close the server and tighten the thumbscrews to secure it in the rack. 12 After all connections are complete, plug the power cord into a power source. Warning: This equipment is intended to be electrically grounded. Your server is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin. This plug fits only a grounded AC outlet. This is a safety feature. If you are unable to insert t...
