Adding External Peripheral Devices
You can add external peripheral devices to the system in several ways:
u
Connect a modem, printer, or other serial (RS-232 compatible) device to a serial port.
Two serial ports are provided. Use cables with 9-pin DB9 connectors. For a cable with a
25-pin DB25 connector, use a 9-pin to 25-pin adapter.
u
Connect a printer or another parallel (Centronics compatible) device to the parallel port.
Use a cable with 25-pin DB25 connectors.
u
Connect a Universal Serial Bus (USB) device to a USB port (only on a system running
Windows 95; Windows NT 4.0 does not currently support USB peripherals). Two USB
ports are provided.
u
On a system equipped with a Small Computer System Interface (SCSI) adapter, connect
SCSI devices to the SCSI port on the adapter. See the documentation delivered with the
SCSI adapter for more information.
u
On a system equipped with a PC Card adapter, insert one or more PC Card devices in the
optional PC Card adapter. You can insert two Type I, Type II, and Type III PC Card
devices in the adapter. Use only Exchangeable Architecture (ExCA) PC Card devices.
See Chapter 4, “Operating Notes,” and the documentation delivered with the PC Card
adapter and devices for more information.
See Chapter 1, “Setting Up the Hardware,” to locate ports on the back of the base unit.
All ports and cables are keyed or molded to make connecting the cables easy. If you encounter
difficulty connecting a cable, ensure that you are aligning the cable connector correctly with the
port.
CAUTION
If you do not use cables supplied by Intergraph Computer Systems, use shielded cables to
prevent excessive electromagnetic interference (EMI). Cables supplied by Intergraph Computer
Systems are designed to reduce the amount of EMI produced by the system.
Opening the Base Unit
To gain access to the system’s internal components, you must remove the side panel. You may
also have to remove the front panel to gain access to some components, such as front-accessible
peripheral devices.
Before opening the base unit:
1.
Turn off power to the system and to the monitor.
2.
Disconnect all cables from the back of the base unit.
