2-2 CHAPTER 2: INSTALLATION

Mounting the Server You can mount a CS/2500 series server on a tabletop, in a two- or four-pole 19-inch rack, or vertically in a wall mount.

Mounting on a Table To mount your server on a tabletop, use the following procedure:

1Place the server on a firm, flat surface.

Do not mount the server at an angle greater than 15 degrees from the horizontal or vertical.

2Make 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.

3Make 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.

4Do not stack objects on top of the server.

Mounting in a Rack 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.

1Fasten 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 if this situation occurs.
