Expansion Slots and Input/Output Connectors

Keyboard Connector: The cable from your keyboard connects here.

Mouse Connector: This is where the mouse cable connects to the server. This port sometimes is called an auxiliary-device or pointing-device port.

Serial Connectors: Your server has two, 9-pin serial connectors (COM1 and COM2). The serial signal cable for a modem or other serial device usually connects here. If you are using a

25-pin signal cable, you need a 9-pin-to-25-pin adapter cable.

Video Connector: The monitor signal cable attaches to this 15-pin connector.

Parallel Connector: This is where the signal cable for a parallel printer or other parallel device connects to your server.

Expansion Slots: The PC Server 704 has four extended industry standard architecture (EISA) expansion slots and six peripheral component interconnect (PCI) expansion slots. You can install PCI or EISA adapters to provide communication, specialized graphics, and sound. Many adapters provide bus-master capabilities, which enable the adapters to perform operations without interrupting the system microprocessors.

The four EISA expansion slots are available for future expansion. Some models might come with a network adapter installed in one of the PCI expansion slots. Disk-array models also come with a PCI RAID adapter installed as a standard feature. The remaining four or five PCI expansion slots are available for future expansion.

Power Connectors: The system power cords connect here.

Note: To see these and other connector locations on the system board, refer to the system-board layout in “The System Board” on page 288.
