What is KVM switch

Company Profile

Originated in 1997 and Established in 2001, Shine East IPC (SEIPC)is now a leading professional IPC OEM/ ODM maker, focus more in KVM switch, LCD KVM console drawer, LCD industrial monitor... etc, mostly related to IPC display & networking field. With employees averagely 8 years experience in IPC/ KVM industry (from IEI, Advantech, Portwell, ProTech IPC...), SEIPC can furnish you with outstanding performance products, competitive prices, quick response and full satisfaction.

Quality Advantage

SEIPC OEM for branded customers in KVM switch, LCD KVM console, IPC system ... etc for years, we understand how to meet quality standard of Japan, Germany customers, we know how to offer durable products with excellent industrial design. Most important, the price you get is the same quality but only half-price to global branded products.

Cost Advantage

With SEIPC's very economic business scale & special operation cost control, our overhead cost is almost one-tenth to the peers ; all SEIPC's suppliers are tuned and refined to match our business model, knowledgeable to control their cost under a sound production plan developed by SEIPC. So all these cost savings reflects into our selling price, yes, customers like you are the most benefits taker, supported by our cost feedback.


SCM Advantage

Supplier Chain Management (SCM) is the key to success of IPC industry, because it always relates to high-mix-low-q' ty production which takes high flexibility. SEIPC is good to this system build years ago and maintains a good relationships with suppliers. Therefore, shortage, delay, spec errors... etc problems of IPC makers are well controlled by SEIPC with mature SCM conducted.

Mechanical / Electronic Engineering design nitch

One of our customer is a Lynux SW worldwide leader, we co-design & develop an outstanding mechanical barebone to fit into customer's existing SW, plus their consign MB, HDD, memory & SEIPC's LCD module design...etc. With this cooperation, we together come out a very successful product now hot-selling in Lynux server industry.

We understand how to customize for our clients, with high-mix-low-volume consideration in cost, production, material stock, lead time...etc, that's why SEIPC maintains good relationships with several worldwide well-known customers.

LVHM Experience Advantage

With years of experience, SEIPC tailors the approach to meet low volume, high mix (LVHM) production needs. We leverage resources to the most, minimize costs, and still maintain our customer-focus model --- SEIPC indeed knows how to run industrial / automation LVHM business. Even with one piece order from customer, it is still our most valued one.


What is KVM switch

KVM introduction

KVM stands for "Keyboard, Video, Mouse." A KVM switch connects one keyboard, one mouse and one video display to multiple computers. This allows users to control multiple computers with only a single set of input and output devices. By sharing the inputs and the display, desktop clutter and cabling requirements can be reduced. A KVM switch may also include other switching functionality, such as for USB ports and audio.


The most common and least expensive KVM switch allows access to two computers. However, switches can be built to handle as many computers as a user requires. To switch between computers, the KVM switch may have a button or dial on the device itself. More sophisticated (corporate level ) switches will allow the user to switch computers by using a keyboard shortcut, also known as a hot key.


A typical use for a KVM switch is in networks with dedicated servers. In everyday use, a server does not need user interaction, rendering a dedicated monitor and keyboard a needless waste of space, money, and power. In larger networks, where servers may be mounted horizontally in large racks, an entire array of servers may share one set of input and display devices via a KVM switch installed directly in the rack, or even a combination of KVM plus LCD monitor & keyboard, mouse into a 1U (4.44cm) height unit.


A recently welcome development is networked KVM (KVM over IP), which requires no physical connection between the keyboard and mouse beyond a standard Ethernet network connection. This potentially allows one user to control hundreds or even thousands of computers from one access point. Wireless routers found in homes offer something similar to this: by embedding a web server into the router, it can be accessed from virtually any connection on the network without requiring physical access to the router.


KVM Switches by Product Category

KVM Device
Starting with simple KVM device (analog) that allows a user connects a monitor, keyboard, and mouse to the KVM device, then uses special cables to connect the KVM device to the computers. Control selection of PCs is switched from one computer to another by the use of buttons on the KVM device, with the KVM passing the signals between the computers and the keyboard, mouse and monitor depending on which computer is currently selected. A good KVM also needs to support all pointing devices and keyboard types, and be easy to configure while supporting high video resolution in an environment of mixed operating systems.

LCD KVM Drawer
The reduction of server footprints in the data center has also led to the growth of KVM drawers. Mounted into a standard 19-inch rack, the drawers offer a multitude of configurations particularly in the LCD monitors with sizes from 15-inch, 17-inch to 19-inch, along with either tilt forward or back; trackballs and touchpad pointing devices; integration with KVM switching products; support for multiple platforms; and security mechanisms. The most common types of servers are mail servers, database/file servers, web servers, and application servers (SAP, ADP). Whether the KVM device is an analog or digital type, it is limited within the office area.






KVM over IP
The analog KVM device was initially developed to make life easier and reduce cabling in data centers that offers more flexibility for IT staffs charged with managing multiple locations. To overcome this limitation, manufacturers developed a digital alternative, known as KVM over IP. KVM over IP connects directly to KVM signals on any computer and is non-invasive to the computer, no added software/hardware. The technology leverages the existing network infrastructure and supports both local and remote users. KVM over IP works in heterogeneous hardware environments and is ideal for managing multi-location data centers and branch offices. The biggest advantage of KVM over IP has no distance limitations.

It allows administrator to log onto the corporate network anywhere to access a server for virtual views of the environment, troubleshoot if any problem arises and repair remotely. However, the digital KVM for local management has the downside of being in-line and thus representing a potential bottleneck, putting overhead on the network as a whole. In order to access over IP is that it relies on the network itself to be up and running in order to get the device, though this too can be overcome by using a dial-in connection for BIOS access, even if the network as a whole is down.

Analog KVM
The majority of KVM equipment shipped today is analog, which is the best technology for local management of devices, sitting out of band and working over UTP (Cat5/5e or 6) or coaxial cabling and hardwire directly to the servers. Aside from the obvious advantage of being out of band and thus non-intrusive to transaction data flows, analogue KVM also delivers a superior video experience for the admin, thanks to better resolution than digital.

Analog can actually stretch to 300 meters away from the data center itself, making it possible for the computer room itself to remain closed yet be managed from outside. To do this, companies deploy what are called KVM extenders, which are a two-box solution comprising a transmitter plugged into the back of the switch and a receiver to deliver the KVM functionality on the desktop. Such products are of particular use in environments such as radio broadcasters, where all the music is nowadays held as MP3 files on servers which must reside outside the actual studio in order to avoid noise.
