1-10 CHAPTER 1: OVERVIEW

The cable between the server and the printer should not be more than 12 feet long, so you must locate your printer physically close to the server.

The printer connector is a female DB-25 equipped with jack posts. Although it resembles an RS-232 serial port connector physically, it is not equivalent electrically. For information on the printer port’s pin assignments, refer to Appendix A, “Pin Assignments.”

Power Supply Module The server includes an autoranging power supply that automatically adjusts to the local power source. You do not have to select the appropriate voltage.

The power supply module is located on the left side of the server’s back panel. It includes the power supply, power switch, fuseholder, and power cord receptacle, as shown in Figure 1-6. The switch is marked according to international I/O convention. When the I side is pressed, the switch is on; when the O side is pressed, the switch is off.

The single fuse is mounted in a removable cartridge. Refer to Chapter 5, “Maintenance and Upgrades,” for information about changing fuses.

The communications server has an international CEE-22 AC power receptacle approved for 6 A operation. The connector has three prongs, with chassis ground on the middle prong. All servers are shipped with power cords. If your power cord does not match your requirements, contact your network supplier.
