Setting Up a Virtual Local Area Network (VLAN)

The Ethernet ports in the Xserve G5 system can support virtual local area networks, or VLANs. A VLAN allows computers and other network devices located on different network sections (or subnets) to act as if they were on the same section. For example, with a virtual LAN, members of the same workgroup who are located on different floors of a building can share the same bandwidth and network devices.

Xserve G5 VLAN support conforms to the IEEE standard 802.1q.

You use the VLAN area of the Network pane of System Preferences to set up and manage VLANS. This part of the Network pane is visible only if your hardware, such as an Xserve G5 system, supports this feature.

To configure a VLAN, log in to your server as an administrator, then open the Network pane of System Preferences and click the VLAN button. Use the Help (?) button in the VLAN pane to display instructions for setting up a VLAN.

Enabling Jumbo Ethernet Frames

The Xserve G5 system provides support for jumbo frames through its Gigabit Ethernet communication. The Xserve G5 support allows packets up to 9000 bytes in size, which facilitates improved network performance.

You can enable jumbo frames on an Xserve G5 system in the Network pane of System Preferences. Use the Ethernet button in the Network pane, configure manually, and choose jumbo as the frame size.

Note: Not all switches support jumbo frame sizes. See your network administrator before implementing jumbo frames if your server is connected to a switch.

Controlling Access to a Connected Keyboard and Mouse

You can specify that when the Xserve G5 system’s enclosure lock is engaged (using the key provided with the system), users will not be able to control the system with a keyboard and mouse that is connected to the system. This control denies input from other USB devices as well.

To enable this security feature, log into the server as an administrator, open the Security pane of System Preferences, and select “Disable mouse and keyboard when Xserve G5 security lock is engaged.”

Important: If you do not turn on the enclosure lock feature in System Preferences, engaging the enclosure lock will not prevent keyboard and mouse use of the system.

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.
