3. To mount your server on a tabletop use the following procedure Place the server on a firm flat surface Do not mount the server at an angle greater than 15 degrees from the horizontal or vertical Make sure that the air intake and fan exhaust vents on the sides of the cover are not blocked Leave at least 3 inches 7 5 cm of free space on both sides Make sure that the rear of the server is not against a wall or other obstruction Leave approximately 6 inches 15 cm of free space at the rear of the server for cable clearance Do not stack objects on top of the server You can order an optional rack mounting kit with your CS 2500 series server 3Com part number 3C759 This kit consists of two brackets nuts and screws that allow you to mount the server in a two or four pole 19 inch rack You need 1 and 2 Phillips screwdrivers to mount the server in the rack You will probably need two people one person to hold the server and the other to attach it to the rack Fasten a rack mount bracket on each side of the server Remove the two outer screws from the sides of the server with the 1 Phillips screwdriver Using the 4 40 screws provided fasten a bracket to each side of the server as shown in Figure 2 1 Tighten each screw securely CAUTION If you use fewer than four screws two on each side to fasten the rack mount brackets to the sides of the server the server can fall and sustain damage The warranty is void
