About the I/O Connectors
You can connect external devices to the input/output (I/O) connectors. The computer's basic input/output system (BIOS) detects the presence of
external devices when you boot (start) or reboot your computer.
NOTICE: When disconnecting external devices from the back of the computer, wait 5 seconds after turning off the
computer before you disconnect a device to avoid possible damage to the system board.

NOTES: Some external devices require you to load software called device drivers into system memory before the
devices will work. These device drivers help your computer recognize the external device and direct its operation.
Instructions for installing this software are usually included in the upgrade kits.
The advanced port replicator (APR) has the same I/O connectors as your computer. In addition, the APR has a second
Personal System/2 (PS/2) connector, a second Universal Serial Bus (USB) connector, and an Ethernet network
connector.
