The Cisco 550X Series is designed to deliver hardware redundancy at the lowest incremental cost. If power to the switch is lost (through loss of AC power or power supply failure), the switch will automatically, and instantaneously, obtain its power from the RPS. This switchover occurs so quickly that there is no loss in traffic or reboot of the device. Cooling fan redundancy is delivered through preinstalled N+1 configuration. A switch can fully support all its capabilities for the life of the product with only N fans. If one of the fans fails, the spare fan automatically takes over, without causing any downtime. The Cisco 550X Series provides an additional layer of resiliency with support for the Virtual Router Redundancy Protocol (VRRP). VRRP lets you extend the same resiliency that stacking provides for individual switches to complete network domains. By running VRRP between two stacks, you can instantly cut over from one stack to another in the event of a problem & continue operating even after a failure. Automatic power shutoff on ports when a link is down LEDs that can be turned off to save power Embedded intelligence to adjust signal strength based on the length of the connecting cable Smart fans in which fan speed is automatically adjusted according to switch temperature to decrease acoustic noise & save power ...

The Cisco 550X Series are the next-generation stackable managed Ethernet switches that provide the advanced capabilities & superior performance you need to support a more demanding network environment at an affordable price. These switches incorporate fan & power hardware redundancy, increasing overall network availability. Cisco 550X Series switches are designed to protect your technology investment as your business grows. Unlike switches that claim to be stackable but have elements that are administered & troubleshot separately, the Cisco 550X Series provides true stacking capability, allowing you to configure, manage, and troubleshoot multiple physical switches as a single device & more easily expand your network. A true stack delivers a unified data & control plane, in addition to a management plane, providing flexibility, scalability, and ease of use because the stack of units operate as a single entity constituting all the ports of the stack members. High-performance 10 Gigabit Ethernet Cisco 550X Series switches break the barrier of 10 Gigabit Ethernet adoption by providing affordable & flexible configurations customized for the demanding network requirements of small & medium businesses. High reliability & resiliency In a growing business in which availability 24 hours a day, 7 days a week is critical, you need to assure that employees & customers can always access the data & resources whenever they need. In these environments, stackable switches can play an important role in eliminating downtime & improving network resiliency. For example, if a switch within a Cisco 550X Series stack fails, another switch immediately takes over, keeping your network up & running. You can also replace individual devices in the stack without taking your network offline or affecting employee productivity. The Cisco 550X Series is designed to deliver hardware redundancy at low incremental cost. Power over Ethernet Plus (Po E+) & Po E Cisco 550X Series switches support the Power over Ethernet Plus (Po E+) standard (IEEE 802.3at). The switches also support Po E on selected ports to power compact switches, high-power wireless access points, or connected lighting. The power is managed in a smart fashion such that only the amount of power the endpoint needs is delivered to it & not wasted. As a result, the switches can support devices that require more power, such as 802.11ac wireless access points, video-based IP phones, surveillance cameras, and more. Po E capabilities simplify the deployment of advanced technologies by allowing you to connect & power network endpoints over a single Ethernet cable, without having to install separate power supplies. Cisco 550X Series switches are also fully backward compatible with IEEE 802.11af Po E & Cisco legacy Po E protocols. ...

To buy the right hard drive it is important that you know the interface type of your computer. The interface type determines the compatibility to a system. Common interface types today are IDE (also known as PATA), SATA, or SCSI. SCSI interface type may come in different pin configurations. Speed & Capacity determine how much data can be stored & how fast the data can be accessed. The higher the capacity, the more data can be stored. Similarly, the higher the speed, the faster the computer can access or write data to/from the hard drive. Cisco 600GB 3.5" SAS 15K.
