(See the illustration above. ) Once you've placed the server in the rack, you can connect the power cord and cables directly to the back panel. See "Connect Cables Directly to the Server" on page 54 for details. You cannot use the cable-management arm on an Xserve system that is installed in a short rack. 50 Chapter 3 Installing Your Server in a Rack Installing the Server in a Two-Post (Telco) Rack The server attaches to a two-post rack at the center of the enclosure, so that the front and back of the server extend beyond the rack. Important: Before installing the server in a two-post rack, make certain that the rack is securely fastened to the floor. Also check the rack's documentation for any specific installation instructions. (These instructions assume that you have previously taken the cover off the server; see "Preparing the Server for Installation" on page 28 for details. ) 1 Attach the small L-shaped brackets to the sides of the server enclosure's cover with four of the short screws provided. Attach the two telco mounting brackets to the server's cover using four of the short screws provided. Orient the bracket so that the screws are at the top. Attach the brackets to holes that are about one-third of the way back from the front panel. Chapter 3 Installing Your Server in a Rack 51 2 Position the cover in the rack at the desired location and screw the flange of the Lshaped bracket to the front of the rack on each side. Important: Be sure to work with another person for this part of the installation. The cover should be held level to avoid changing its shape before the screws are inserted to hold it in place. Attach the cover to the telco rack mounting posts using four of the screws provided. Be careful not to overtighten the flange screws. Doing so could change the shape of the cover slightly and make it difficult to slide the server into the cover. 3 Lift the server to the level of the cover and slide the server into the cover. Insert the server into the cover and slide it all the way back. 52 Chapter 3 Installing Your Server in a Rack 4 Secure the server in the rack by tightening the thumbscrews on the front. Important: Take care not to apply too much pressure on the thumbscrews if you use a power screwdriver or drill. The torque applied to the thumbscrews should not exceed 6. 0 inch-pounds, and the rotation speed should not exceed 200 rpm. Tighten the two thumbscrews to secure the server in the rack. To secure the drive modules in the server, use the enclosure key to lock them in place. Remove the plastic optical drive protector. Save it and reinstall it if you ever move the server to another location. 5 Remove the optical drive protector from its slot. Be sure to store this protector in a safe place and always reinsert it before moving the server to another location. 6 To further secure the server and prevent removal of the drive modules, use the enclosure key (supplied with the server) to fasten the security lock on the server's front panel. (See the illustration above. ) Note: You cannot use the cable-management arm on an Xserve system that is installed in a two-post rack. Chapter 3 Installing Your Server in a Rack 53 Connect Cables Directly to the Server Once the server is secured in the rack, you can connect the cables and power cord directly to its back and front panels. You must connect the cables and power cord directly if you mount the server in a two-post rack. Follow these steps to connect cables for network connections and peripheral devices directly to the server (without mounting the cable-management arm). 1 Gather the cables and devices you will connect to the server's back panel. Make certain that each cable has the proper connector and that it is designed for use in a highcapacity server. (Check the documentation for each peripheral device or cable to determine that it can be used with the server. ) 2 Label each cable so that you can locate a specific cable quickly and avoid errors when disconnecting cables.
