  Provided below is an example of the required dispatch from the boot process which can be used to identify which IOS Version and Feature Sets the router is currently loading. Cisco Internetwork Operating System Software IOS (tm) 3600 Software (C3620-IK9O3S7-M), Version 12.3(25), RELEASE SOFTWARE (fc1) Turn your attention to line 2 where you see  C3620-IK9O3S7-M ; this displays the features that are included in the image and the loading type  (which will be discussed later)  for the image that is currently be loaded by the Router. Following the feature set being loaded you can also see the Version of the IOS. As shown in this example, the router is currently booting IOS Version 12.3(25) The most common way of obtaining IOS identification information is by using the  show version  command. This command shows various information pertaining to the Cisco IOS Version and Feature Set as well as hardware information about the router. The textbox below shows the dispatch of the  show version  

Understanding Medium-Dependent Interface (MDI) Medium-dependent interface (MDI) is a crucial concept in computer networking. It refers to the physical and electrical/optical interface between a network device's physical layer implementation and the physical medium used for data transmission. MDI plays a significant role in ensuring proper connectivity and communication between network devices. ### Key Aspects of MDI: * Physical interface: Defines the connector type and pin layout * Electrical/optical characteristics: Specifies signal levels, timing, and transmission methods * Compatibility: Ensures interoperability between different network devices ## Introduction to MDI-X Ethernet over twisted pair introduces an additional interface type known as medium-dependent interface – crossover (MDI-X). This interface is designed to address specific connection requirements in Ethernet networks. ### MDI-X vs. MDI: * MDI: Standard interface used in most network devices * MDI-X: Crossover inte

## Data Center E-Waste: The Basics E-waste encompasses all forms of electronic products that reach the end of their useful life and pose environmental hazards if not properly disposed of. Within data centers, critical infrastructure such as servers, network switches, and power supply units, contain harmful chemicals including lead and mercury. When discarded improperly, these substances can leach into ecosystems, affecting flora, fauna, and human health adversely. Additionally, developing nations often bear the brunt of e-waste disposal, facing significant social and environmental impacts. ## Will AI Make E-Waste Worse? With the surge in AI technology, particularly generative AI, there has been an increased deployment of highly specialized hardware like Graphical Processing Units (GPUs). These devices are essential for training AI models, a process that necessitates high parallel computational power. This intensity results in the rapid obsolescence of such hardware, as their utility pe
