Important: To open the server with the cables attached, you must install and use the cable-management arm. You can use the cable-management arm only with a four-post rack.

If your rack is the same depth as the server (or an inch or so deeper), you attach the cable-management arm to the left rear post of the rack. If your rack is several inches deeper than the server, you attach the cable-management arm to the left brace that supports the back of the server.

The steps that follow explain how to connect cables to the cable-management arm and attach the arm either to the left rear post or to the left brace at the back of the server.

Connect Cables to the Cable-Management Arm

Before you attach the cable-management arm to the rack or support brace, you need to connect the cables to the arm.

Important: To use the cable-management arm, your cables must be approximately 3 feet longer than the distance between the server and its peripheral devices. This extra length may not be feasible for some cables, such as SCSI cables. In this instance, you can bypass the cable-management arm with a shorter cable. But you must disconnect that cable when you open the server.

Follow these steps to connect the cables to the cable-management arm.

1Gather the cables you will connect to the server’s back panel, along with the power cord. (Use the cord supplied with the server.)

Make certain that each cable has the proper connector and that it is designed for use in a high-capacity server. (Check the documentation for each peripheral device or cable to determine that it can be used with the server.)

2Attach an identifying label to each cable you are connecting.

The labels allow you to locate a specific cable quickly and avoid errors when disconnecting cables.

3Hold the cable-management arm in the orientation you will use to attach it to the rack or support brace.

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.
