Mac mini (Power PC): external ports and connectors

The Mac mini and Mac mini (Late 2005) have an Input/Output (I/O) panel on the back of the computer that contains various ports and connectors. Here's a closer look at each one.

Power Port
This port is used to connect the Mac mini's power supply. The Mac mini's power connector is very similar to that of the Apple Cinema Display, so take care to differentiate the two connectors if you set up the Mac mini with an Apple Cinema Display.

Ethernet Port (10/100 Base-T)
The Mac mini features a built-in 10/100 Mbit/s (megabits per second) Ethernet port. You can connect your Mac mini to a cable or DSL modem, hub, switch, router, or even directly to another Macintosh computer, using an Ethernet cable. The connected device can be either 10Base-T or 100Base-TX; the Mac mini will automatically detect what type it is. You don't have to use an Ethernet crossover cable to connect to other Ethernet devices.

Modem Port (on some models)
Mac mini computers that come with a built-in 56K V.92 modem will have a telephone connector port (also known as an RJ-11 connector) on the I/O panel. The modem features bit rates up to 56 kbit/s and supports V.90, V.92, and K56flex modem standards. (Actual modem speed depends on the connection rate and other factors.) It also features group 3 fax modem bit rates up to 14.4 kbit/s, and provides an analog sound output for monitoring the connection progress. The Mac mini sees the modem as a serial port that responds to standard AT commands.

Display Port
The Mac mini has a DVI-I port that supports DVI-compatible displays. You can also use the included DVI-to-VGA adapter to connect a VGA monitor. The display port supports analog resolutions up to 1920 x 1080 pixels.

Two USB (Universal Serial Bus) 2.0 ports
The Mac mini has two USB 2.0 compliant ports. You can connect both USB 2.0- and USB 1.1-compliant devices to these ports (they use USB Type A connectors, which have four pins each). The USB 2.0 ports support low-speed, full-speed, and high-speed data transfers at up to 1.5 Mbit/s, 12 Mbit/s, and 480 Mbit/s, respectively.

One FireWire 400 port
The Mac mini features one FireWire 400 (IEEE 1394) port. The port supplies 8 watts of power. The FireWire 400 port supports data transfers at up to 400 Mbit/s. This port can be used to connect an iPod, as well as other accessories such as a video camera or external drive.

Audio output
The headphone/line audio output jack accommodates analog audio with a 24-bit, 32-192 kHz D/A converter. This port accepts a standard 3.5 mm audio plug.

Security Slot
This slot is designed to fit a lock and cable to prevent theft. Such locks are available through the Apple Store.
