The Avocent SwitchView SC540 is a 1 user, 4 system, dual monitor (dual-head) secure KVM switch with USB, DVI-I (dual-link), audio, CAC support, and intrusion detection. The SC540 offers secure access for any desktop environment where security is mandatory. With USB Common Access Card (CAC) reader support, three levels of physical security, and controlled USB connectivity, you can consolidate multiple workstations of varying security classification levels with one keyboard, monitor and mouse without compromising network security. Dual link video offers uncompromising video quality up to 2560 x 1600 @ 60 Hz, while dual-head video supports the most demanding two monitor workstation requirements.

The SwitchView SC540 switch allows desktop IT administrators to deploy a single CAC reader that will switch to all computers connected to the switch. (CAC support is required for all government employees attempting to log in to government systems and is specified in the Homeland Security Presidential Directive 12 [HSPD12].) These switches include three layers of tamper-proof hardware security at the desktop. In addition SwitchView SC540 ensures that only USB human interface devices (HID's) function on target computers by constantly monitoring all devices attached to the console ports. These switches ignore communication from non-HID's (such as flash drives, hard disk drives, cameras and printers) when switching data to the target.

Avocent SC540 Features & Benefits:

  • NIAP Common Criteria validated to EAL4+.
  • Software Security. U.S-designed firmware allows only keyboard, mouse and common access cards (CAC) human interface devices (HID) to switch to the target computers. Devices considered unsecure, such as fl ash drives or other mass storage devices, cameras and all other USB devices, are strictly prohibited by the switch firmware.
  • Physical security:
    • Tamper-evident tape: A visual indication of an attempt to gain access to the internal components of the switch
    • Chassis intrusion detection: Prevents malicious tampering with the switch. If the cover is removed from the switch, the switch becomes inoperable and the LEDs flash
    • Locked memory: Prevents tampering and reprogramming of the firmware
  • Secure channels: Four fully secure channels isolated to 60db. Safely switch between computers operating at different classification levels - without compromising network security.
  • Clears buffer: Automatically clears the keyboard buffer immediately after data is transmitted through the switch, so no data is ever left in the switch

Question: I connected two monitors to the console ports on the KVM but only the monitor in the first console port will display; any ideas.
Answer: Unfortunately, due to the varied nature of user environments, detailed product support is beyond the scope of this simple product FAQ.

That being said, you can try a couple of things. Confirm all cables are attached securely. Ensure that both monitors function individually. Make sure the target computer is capable of, and configured for, dual monitor display (requires a dual monitor capable video card or two cards).

Question: Do you have the Avocent SwitchView SC540 Secure KVM Switch instock and can you ship it overnight?
Answer: Thank you for your inquiry. Please call your KVM Switches Online representative at 1-877-586-6654 for all stocking questions.

Question: This product is not advertised as dual monitors but it does have a dual-link DVI. Please confirm, will the Avocent SC540 work with dual monitors?
Answer: Thank you for your inquiry. You are correct; the SC540 does have support for dual monitor setups.

It should be noted, however, that the dual-link reference is to the amount of bandwidth provided by each connection (dual-link will provide twice the data bandwidth for each DVI connection to support higher resolutions than can be achieved with a single link DVI connection). It is the dual-head aspect that allows this KVM to support dual monitor setups.

Thank you for mentioning this, we will be sure to clarify that this switch will support dual monitor setups.

Question: Does the dual monitors option allow to "monitor" one computer screen and work (keyboard/mouse/screen) from another?
Answer: Thank you for your inquiry. The dual monitor feature of this secure KVM allows a single target to access both monitors at once, for an extended desktop environment. Unfortunately, it will not display information from different targets on separate displays.

A secure multi-viewer KVM switch, like this one from SmartAVI https://www.kvm-switches-online.com/k424f-sh.html, may provide the functionality you are looking for.

Question: Is there a keyboard function to switch ports without pressing the front buttons?
Answer: Thank you for your inquiry. For security reasons, a user can only switch targets via the front push buttons.

Question: What adaptor cable do I need to use for DVI to VGA?
Answer: Thank you for your inquiry,

Which adapter you would use depends on which direction you are trying to adapt VGA to DVI -

If you want to connect a VGA cable to the switch (DVI port -> adapter -> VGA cable -> computer or monitor): VAD-28 (DVI Female to VGA Male)
If you want to connect a DVI cable to a VGA computer / monitor from the switch (DVI port -> DVI cable -> adapter -> VGA port for computer or monitor): VAD-27 (DVI Male to VGA Female)
