RackMountSales – Cat5 KVM Switches Or Traditional DB-15 Style?

RackMountSales – Cat5 KVM Switches or traditional DB-15 style? There are many choices when it comes to buying a KVM Switch. A traditional KVM Switch uses a DB-15 or other similar interface on the KVM Switch side and a VGA USB Cable on the server side. Lengths for these cables are usually limited to 3 or 4 sizes due to signal degradation and manufacturing SKU limitations. However, for most typical applications these KVM switches fill a need at an affordable price. These older legacy KVM Switches used to use a bulky, difficult to manage cable set. Over the years, the cables have been redesigned with thinner material making cable management less of a concern.

kvm switchesCables can be easily routed to the sides of the server rack minimizing server exhaust blockage for “at the rack thermal best practices”. Hot exhaust generated from servers can cause a number of issues if not managed properly. Keeping KVM cables routed to the side will help keep them from direct exhaust heat as well as eliminate air flow blockage. For installations with 8 to 16 servers, the DB-15 style KVM switch may be all that is needed. Cable lengths add some flexibility as they are typically available in a 6’, 10’ or 15’ lengths. In addition, these KVM switches offer some other optional features. A 2 console KVM switch features a remote Cat5 receiver which can be positioned up to 1,000 feet from the KVM Switch and allow 2 users simultaneous access to the target devices on the KVM Switch. Another option is the KVM Over IP style switch which is also a 2 console solution. One local console and one remote IP KVM Console allows for 2 simultaneous users as well. Having an IP webserver built into the KVM switch allows remote BIOS level access to your target devices which can come in handy for quick resets and trouble shooting.

RackMountSales – Advantages of LED Backlight LCD Panels

RackMountSales – Advantages of LED Backlight LCD Panels. CCFL  backlight technology is still common on small rackmount LCD Panels such as 17”, 19” and 20” size screens. However, the newer high resolution and high brightness rack mount LCD‘s have shifted to LED (Light-Emitting Diode) technology due to several advantages. The LED backlight LCD’s consume less power and are thinner and lighter than the CCFL backlight technology.

LED edge-lit technology (compared to other LED technologies, ie RGB and Full Array LED) helps keep the cost down however, it is still more expensive than CCFL technology.  In addition, the LED Backlight LCD panels are used for high brightness LCD’s without seeing a drastic increase in heat generated. The LED rack mount LCD screens also have a longer life than CCFL technology. The new 17” wide screen, and 21” high resolution rack mount LCD panels are built with LED backlight technology. So, to summarize, LED backlight LCD Panels are lighter, use less energy, and are typically used for high resolution and high brightness monitor applications when applied to the rack mount monitor industry.

RackMountSales – What is CCFL LCD Panel technology?

rackmountsales RM11417RackMountSales – What is CCFL LCD Panel technology?  CCFL technology (Cold Cathode Fluorescent Lamp) has been around in the LCD Industry for quite some time. This LCD Panel technology is still the most commonly used in smaller screens used for laptop computers and rackmount monitor applications. The softer image causes less strain on the eyes which in some cases, where the user is going to be in front of the LCD Screen for long periods of time can be advantageous. Although, one of the trade-offs with this older technology is the fact that CCFL backlight consumes more power and requires higher voltage.

The reason for this is because the technology uses a fluorescent tube that is connected to an inverter board which provides power to the backlight.

In turn, higher voltage requirements means more heat is generated than with the newer LED rack mount screen technology. The CCFL backlight LCD Panels are also thicker and heavier than the newer LED backlight technology. When it comes to rack mount LCD Panels and drawers, in most applications, the user is not required to spend extended periods of time viewing the information on the screen. The newer LED backlight technology may be another option to consider for rackmount LCD Panel and drawer applications.

Check Your Rack Rail Depth When Ordering Rack Mount LCD Drawers

The new designed rack mount LCD drawers offer a wider range of mounting depths. The 1U drawers can now be mounted in many different configurations ranging from a 2 post relay rack, all the way out to 34.5” of depth. There are several different size rear mounting brackets available to accommodate the wide mounting range.

The default brackets will mount to a traditional server depth of 29”. Shorter brackets are available for AV racks or other equipment racks. The rackmount monitor chassis depths vary depending on the configuration. When integrating a KVM Switch, the chassis depth will typically be several inches deeper. The same stands true when adding DC power and other Video Input options. In addition, some of the 1U rack mount monitor drawers are designed as shorter depth units. Depending on the screen size, the 17” rack mount consoles and the 19” LCD sizes dictate the chassis depth.

Tools to monitor data centers and other environments

Early warning detection and monitoring from environmental threats can help avoid a catastrophic event and minimize the chance for threats to the uptime in your data center. Simple, affordable monitoring tools for temperature, humidity, water detection, and physical access are all available with the full line of data center monitoring solutions.

Basic monitoring is available for under $220!
POE appliances are an option on many products
The combination of analog inputs and digital ports allow for management of many different threats to the date center. Relay outputs are also available for both monitoring and control.

The entire line starts with an appliance about the size of a match box and continues to a 1U appliance that includes analog, digital, and relay ports.
For the benefits, the cost is easy to justify as down time can be very expensive. All of these appliances have built in web servers and send alerts via SNMP and email. User definable data make the communication intuitive and efficient. It is also important to assess the risk in the date center and determine where threats might originate. The data center location and its surrounding environment will determine which sensors should be used and where they should be positioned.

 

 

 

 

1U Keyboard Drawers – Which is the right fit and function?

When it comes to rackmount keyboard drawers, there are several things to take into consideration before making a decision on which model is the best fit. There are now 2 post relay rack mounting brackets available as well as the traditional 4 post 1U rack mounting with several depths. A traditional server will typically require a mounting depth of around 29.5″ depth which is a perfect depth for the full size 1U drawer. However, for shorter racks typically used in AV and Broadcast environments, the rack depth can be considerably less. In this case, a keyboard drawer with a shorter chassis depth is the right solution. By combining a high resolution rack mount LCD along with a short depth keyboard, you can have an efficient ergonomic to and cost effective solution, all in 1 rack. Be installing the keyboard and sit down height (around 30″) or at stand up height, (between 36′ to 40″) the panel can be positioned above the keyboard at a perfect viewing angle. In addition to depth and positioning, certain hardware applications can require specific keyboard layouts. SUN hardware typically will require a keyboard that has SUN hotkey functions built into the drawer. In addition, MAC systems also have a specific keyboard layout. So, it is important to review all rackmount keyboard drawer options when building our a rack configuration.

High Resolution Rack Mount LCD Panels & Drawers

 

Although 1920 X 1080 resolution has been around for years on large LCD’s, only recently has the 16 : 9 format become available in the smaller sizes. The standard 6U 17″ Wide Screen rackmount LCD will eventually replace the 4:3 17″ Screen. The High Resolution 17″ screens are an ideal size for mounting in standard EIA rack mount rails.  Available with SDI as an option, broadcast applications and on set movie production can now be supported at a different level. In addition, when the U space is available, another common LCD Panel size is the 8U 21.5″ Rackmount LCD Panel which still fits on a 19″ EIA rail configuration. A common application for LCD Panels and drawers is adding a resistive touchscreen eliminating the need for storing a keyboard with a rack mounted configuration.

Tips for Choosing the Best KVM Switch

A KVM switch or a Keyboard, Video, and Mouse Switch is used for the purpose of sharing a mouse, monitor, and keyboard on many computers. If you are in the process of selecting a KVM switch, then here are some tips to help you choose the right one. Read more »

How to Select a Rack Mount Monitor

A Rack Mount monitor is used to display a video image from any video source. The entire assembly usually consists of a LCD display that is fitted onto a Rack Mount enclosure. This monitor is usually used along with a server or industrial computer. The monitor comes along with equipment or server racks that are designed to EIA 19” standards. Following are the factors that you should consider before selecting Rack Mount monitors.

The type of rack

The type of rack where the monitor will be installed will depend on the position where the rack is being installed. The most commonly used rack is a 4 post rack or a fully enclosed server rack. This is used in almost all places where servers and related equipment are installed. But, if you want to install your monitor in a place like a telecom closet where space is a consideration, then you should go for a 2 post rack.

The type of mounting rails

While buying Rack Mount monitor, you should ensure that it fits well into the server rack. This will in turn depend on the type of mounting rails that are present in the server rack. Modern racks which come with rails that have square holes can be used to fit almost all types of monitors. Other types of rack come with rails that have round holes, or tapped rails and you may have to use special equipment for mounting the monitor on it.

The need for independent sliding drawers

If you think closed doors will become a concern for you while monitoring, then you should go for a combination of a keyboard and a dual sliding monitor drawer. Such drawers will allow storing the keyboard while allowing the monitors to remain up. These dual sliding units combine the handiness of the keyboard drawer with the visibility of a rackmounted LCD panel, all in one unit.

Check for KVM support

While buying a Rack Mount monitor, upi may want to consider whether it has an integrated KVM switch option. This goes a long way in saving space. There are numerous styles of Rack Mount monitors which are available with KVM integrated switches. The latest technology also allows you to have KVM over IP remote BIOS level access over a web browser.

The benefits of a touch screen

One of the specialties of a touch screen monitor is having a touch sensitive screen. This feature allows the user to interact with the computer program in an easy manner. It sometimes even eliminates the need for a keyboard. So, do make sure that the Rack Mount LCD that you select is equipped with a touch screen feature.

The KVM Switch Explained: Different Types for Different Situations

rackmount touchscreenA keyboard-video-mouse (KVM) switch is a hardware device designed to allow users to control multiple computers using a single keyboard, monitor, and mouse. While most individual computer users may not need these functions, it’s a different story in the business sector.

Today, you will never see a company that has only one computer. Usually, the bigger the company is, the more computers it needs. As the number of computers in a business grows, the increasingly imminent problem is how to effectively operate all of them. A quality KVM switch provides a solution for this concern; with different types of these devices for specific situations.

KVM over CAT5 Switch

An analog KVM switch operates using a direct cable connection. This type of KVM utilizes a closed loop network of CAT5 cables to allow users to control computers from up to 1,000 feet away. The KVM over CAT5 switch is a secure system that protects your company’s data from any outside threat such as hackers. Because it works in a closed loop network, the only way to access information stored in your system is through the KVM console within your facility.

KVM over IP Switch

In contrast with the KVM over CAT5, a KVM over IP switch allows a user to operate computers hooked up to the switch using Internet connectivity. Most user interfaces for such a system are browser-based; but some KVM over IP switches come with a software-based interface that enables better operation. Depending on the model, a KVM over IP switch can enable access BIOS boot functions, allowing a user to have as much control over the whole system as with operating the system personally.

Multi-User KVM Switch

kvm switchThis type of KVM switch allows multiple users to simultaneously access the entire system. Usually, an Over-IP access, KVM extender, or a combination of both is used to enable access by multiple consoles.

Integrated KVM Switch

Also called rack consoles, integrated KVM switches are mostly used for space-saving purposes. As the name suggests, the display, keyboard, and mouse units are all integrated into the switch to form one console. The console is then positioned into the server rack along with all the servers and computers. Many rackmount monitor solutions, such as Crystal Image Technologies Inc., even offer rackmount touchscreen consoles which eliminate the need for a touchpad or trackpad.
