About PCI-X Cards for the Server

The server’s two PCI-X slots accept cards up to 12 inches long. (Some models come with a card installed in one or both slots.) Install only expansion cards that are compatible with Mac OS X and the PCI-X 2.2 standard, or standard PCI cards that are compatible with Xserve G5 systems and Mac OS X.

Note: The frequency (often called speed) of both PCI-X slots is governed by the speed of the slower card when two cards are installed. If only one card is installed and its speed is 133 MHz, the card operates at 133 MHz. If a second card is installed, the 133 MHz card operates at a maximum speed of 100 MHz.

PCI-X Card Requirements

Criteria for PCI-X cards you can install in the Xserve server are summarized in the table below.

PCI-X cards or PCI cards in Xserve G5

32 or 64-bit data width

33, 66, 100, or 133 MHz frequency

(133 MHz is available only when a single card is installed.)

If two cards are installed, both cards operate at the speed of the slower card.

3.3volt (V) signaling 7 to 12 inches long

Important: The PCI-X card must have a 3.3 V connector or a universal connector to fit into the server’s expansion slots. Cards with a 5 V connector will not work in this server.

Power Consumption of Cards

Maximum power consumption for both expansion slots combined should not exceed 30 watts (W). Check the documentation that came with each card to be certain that the cards don’t exceed this power consumption.

Installing a PCI-X Card or PCI Card

Follow these steps to install a PCI-X card. or PCI card

1Shut down the server.

Be sure to alert users that the server will be unavailable for a period of time.

2Disconnect the power cord from the back panel of the server. (If the cable- management arm is not attached, you will also have to disconnect cables from the back panel.)

Warning: The only way to disconnect power completely is to unplug the power cord. Make sure that the cord is disconnected before removing or installing any components inside the server.

G5 specifications

The Apple G5, introduced in June 2003, marked a significant advancement in personal computing with its innovative architecture and powerful performance. It was the first desktop computer to feature a 64-bit architecture, which allowed it to process larger amounts of data more efficiently than its 32-bit predecessors. The G5 was equipped with the IBM PowerPC 970 processor, which operated at speeds ranging from 1.6 GHz to 2.7 GHz, making it a formidable contender in the market for both personal and professional use.

One of the standout features of the G5 was its aluminum chassis, which not only gave it a sleek and modern look but also aided in heat dissipation. The innovative design allowed the G5 to maintain lower operating temperatures regardless of the loads it handled. The G5 was famous for its quiet operation, thanks to a temperature-controlled, variable-speed fan system that minimized noise during regular use while still providing adequate cooling during intensive tasks.

In terms of memory, the G5 could support up to 8 GB of RAM, utilizing DDR SDRAM technology that provided enhanced performance in multitasking and complex applications. For graphics, the G5 offered powerful options, including dedicated GPU support from NVIDIA and ATI, enabling users to perform demanding tasks such as video editing and 3D graphics rendering with ease.

The connectivity options on the G5 were well thought out, including built-in USB 2.0 and FireWire 800 ports, which supported high-speed data transfer for external devices. In addition, the G5 featured an Ethernet port for networking capabilities, making it suitable for both home and office environments.

The G5 also ran on Mac OS X, which was optimized to take full advantage of its hardware capabilities. With its Unix-based foundation, Mac OS X provided users with a stable and secure operating environment, complete with a plethora of software applications tailored for creative professionals, including those in graphic design, video editing, and audio production.

Overall, the Apple G5 was a groundbreaking machine that successfully combined advanced technology, stylish design, and robust performance, earning a dedicated following among professionals and enthusiasts alike. Its legacy continues to influence Apple's approach to desktop computing, marking a pivotal moment in the evolution of personal computers.
