Which Ethernet Cable Should You Use — Cat5e, Cat6 or Cat6a?

The decision of whether to use Category 5e, 6 or 6a cables to wire your Ethernet network pretty much comes down to cost, data transfer speed and connection distance. All use RJ45 connectors to patch into your network via server, router, computer or other hardware. As well, all support Power over Ethernet (PoE). Otherwise, each cable has a different standard.

PDU Power Management – Local Views with Remote Possibilities

Remote-PowerSometimes, let me rephrase that, most of the time, the network administrator has more than just the data center to manage (i.e. network closets, user systems, etc.) and if he only has local metering, he may not know when a particular load is exceeding capacity if he is not physically in the data center location. What can help with this? On-the-go power monitoring, or as the technical crowd calls it, remote power management, can help! Right away if you’re the network administrator your mind jumps to getting things done quickly and efficiently. To know your power needs, you have to have devices in place that can be monitored and managed remotely. This not only goes for the UPS, but also their output distribution sources such as PDUs. Having intelligent PDUs with remote monitoring and management brings certain advantages to the table depending on the functionality that you require. What are they? [Read more…]

Connect 10Gb Equipment to 40Gb Switches Instantly with All-in-One Fiber Patch Panels

n48k15m8l60b-front-lAs faster network speeds emerge, the challenge of integrating different generations of equipment into your network infrastructure becomes more and more prevalent. Many application engineers meet this challenge with custom breakout cables, which can be quite costly and are more of a workaround than a real solution. [Read more…]

What’s the Difference Between Basic and Smart PDUs?

PDUMNH20HVAT-FRONT-LA rack power distribution unit (PDU) is a device with multiple outlets designed to distribute power to networking equipment within a rack, including servers, storage devices and other equipment. For example, let’s say you have a 42U rack cabinet loaded with 42 1U servers, that’s 42 cords you have to find outlets for. PDUs solve this problem by taking the power supplied to the rack and distributing it via multiple outlets to the rack’s servers and networking equipment.

What Is the Difference Between Shielded and Unshielded Network Cables?

When installing or updating your network infrastructure, there are a variety of network patch cable types to consider. Among the choices to be made is whether to install shielded twisted pair cables (STP) or unshielded twisted pair cables (UTP). Twisted pair cabling consists of two conductors of a single circuit twisted together to help reduce electromagnetic interference (EMI) or “noise”. [Read more…]
