NEC MH4500 manual Installing the System, Connecting Peripherals, Connecting the Power Cords

Installing the System

How you install the system depends on whether you have the stand-alone pedestal unit or the rack-mounted unit. If you have the pedestal unit, install it at your site and connect peripherals and power as explained next.

If you have the rack mounted unit, you need to install slide bars on the sides of the unit before it can be installed in a standard EIA-compatible 19-inch equipment rack. You must also install rack extension brackets and slider assemblies in the rack for the unit to mount on. See “Attaching the Outer Slide Bars to the Chassis” and Preparing the Rack” later in this chapter for procedures. Once your rack unit is in the rack, connect peripherals and power as explained next.

Connecting Peripherals

If your system normally operates without a monitor, keyboard, or mouse (for example, as a network server), you must install them to configure the system. You may remove them after running the System Setup Utility (SSU). For information on running the SSU, refer to Appendix B of this User’s Guide.

Refer to the preceding figure and connect your keyboard, monitor, and mouse. Connect any external peripheral devices such as a printer by following the instructions included with the device.

!CAUTION

System damage may result if the keyboard/mouse cable is connected or disconnected when power is applied to the system.

Connecting the Power Cords

The system contains two 400-watt power supplies. Each power supply is designed for automatic sensing of 115 or 230 Vac power, eliminating the need for a line voltage selector switch. The power supplies operate at a frequency of 50/60 Hz.

The system operates with both power supplies connected to power. Each power supply is separately connected to a power source with its own power cord.

Connect each power cord as follows.

1.Plug the female end of the AC power cord into its socket on the back of the Tpower supply.

You may need to slide the plug-lock away from the socket to allow insertion of the plug into the socket.
