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.
