General Information:

Emerald is the first Enterprise KVM Extension and KVM Matrix Switching solution that delivers pixel-perfect video with 2K/HD or 4K/60 resolutions at 10 Bit color depth over an IP network.

The flexible and scalable system supports any number of workstations and servers. In addition, it simplifies virtual access, making it easy for you to use any combination of physical and virtual servers.

It provides operators and administrators with fast and easy-to-use access to their target PCs/servers with premium video quality and a rich peripheral set supporting stereo audio and up to any four true emulated USB 2.0 devices including Wacom® tablets. Administrators will like comprehensive management with convenient configuration options in line with high-level network security and reliable 24/7 operation.

An Emerald KVM network may start small, but it's infinitely scalable to meet your expansion needs and future technology path just by adding endpoints, with no additional chassis or cards required.

System by Design

Emerald comprises of a choice of transmitters connecting computers or virtual machines to the system and receivers connecting the user consoles. High-performance Emerald network switches with 12, 28,- 32-, or 48 ports ensure trouble-free KVM over IP extension and matrix switching connections. A range of SFP/SFP+ transceivers proofs best performing video quality and KVM extensions over the required distances.

Use the Emerald transmitter to connect DisplayPort servers with resolutions up to 4K60, transparent USB, serial, and audio to your Emerald System.

Instant access across the entire enterprise

Emerald makes your migration painless, enabling you to scale access infinitely and gradually across buildings, campuses, and the wide-area network, using your existing network infrastructure - with switching between sources at speeds of less than half a second.

Digital video at its best

Emerald is the first KVM platform that supports pixel perfect 4K DisplayPort video at 60 Hz over standard IP network switches. Image transmission with mathematical lossless compression visualizes every single pixel at 60 fps with 10-bit color depth.

If you're not ready for 4K, start with the Emerald 2K options, supporting one or two full HD DVI channels, and migrate to 4K at your own pace by transitioning individual user groups when the need arises.

Virtualization

More and more physical servers are being replaced by virtualization, allowing better performance, availability, scalability, and return on investment. Emerald simplifies access to both physical and virtual servers with virtual machine support for VMware, Microsoft, and Citrix, using RDP 8.1, RemoteFX, and PCoIP, among others.

Fail-safe operation

All Emerald transmitters and receivers feature copper or fiber connectivity through one (HD) or two (4K) flexible SFP+ slots.

Your 24/7 operation requires network resilience. Use the redundant network ports on the Emerald units to provide continuous, uninterrupted operation even if one network link experiences loss-of-service. Connect the endpoints either through two alternative direct links, a direct link, and a network connection or two independent networks.

    What is a network switch and what does it do?

    Are there different types of network switches?

    There are two main types of network switches, unmanaged and managed. The essential difference is the capability to configure the operation of a managed switch to customize and optimize network traffic for specific applications.

    Unmanaged Switches

    Managed Switches

    Where do you place network switches?

    Network switches are usually placed on a desk or table, mounted on a wall, or mounted in a rack. CompSource offers unmanaged desktop switches (with metal or plastic housing) and both unmanaged and managed rack-mount switches with metal housing and a built-in PDU (Gigabit Ethernet Switch PDU Combos).

    What is a Gigabit Ethernet Switch PDU Combo?

    CompSource offers an exclusive line of unmanaged and managed Gigabit Ethernet switches that have Power over Ethernet (PoE).

    Factors to Consider

    Does your application require a managed switch?

    If your application involves controlling network traffic, you will need the features of a managed switch. The following are some examples of tasks that require a managed switch:

    • Controlling access between departments within your LAN
    • Running many bandwidth-intensive applications simultaneously
    • Giving important data greater priority in your LAN
    • Improving the performance of a busy network
    • Implementing VoIP, wireless LANs or other advanced services

    How many devices do you need to connect to your network?

    Make sure you select a switch with enough Gigabit (10/100/1000 Mbps) Ethernet ports for the devices you want to connect to your network. If you think you'll add more devices in the future, choose a switch that will give your network room to grow.

    how many devices do you need to connect to your network

    Do you need to connect multiple network switches?

    If you plan to connect multiple network switches, look for models with SFP uplink ports (also known as Mini-GBIC ports). SFP uplink ports are connection points for SFP (small form-factor pluggable) modules that allow the switch to uplink to other switches using optical fiber cabling.

    Power over Ethernet (PoE) uses existing network cables to power connected devices, such as VoIP phones, wireless access points and surveillance cameras. If you need this functionality, look for a switch with Gigabit Ethernet ports that support PoE. Make sure the power per port (in watts) and the total power budget of the PoE ports meet the needs of your electronic devices.
