SwitchView® SC420, SC440 and SC540 Enhance Security at the Desktop  
Proven and Secure Access for Any Environment  
Switchview SC420, SC440  
and SC540 Switch Benefits  
The Avocent SwitchView SC420, SC440 and SC540 KVM switch series offers proven,  
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. Dual head video  
(SC540 only) supports the most demanding workstation requirements  
ƒ NIAP Certification. The SwitchView  
SC420, SC440 and SC540 are in  
process for NIAP Common Criteria  
validation to EAL4+.  
ƒ 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 flash drives or  
other mass storage devices, cameras  
and all other USB devices, are strictly  
prohibited by the switch firmware.  
ƒ Physical security:  
The SwitchView SC420, SC440 and SC540 switches allow 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].) Both  
switches include three layers of tamper-proof hardware security at the desktop. In addition,  
SwitchView SC420, SC440 and SC540 switches ensure 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.  
à a) Tamper-evident tape: A  
visual indication of an attempt  
to gain access to the internal  
components of the switch  
à b) 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  
à c) Locked memory: Prevents  
tampering and reprogramming of  
the firmware  
ƒ Secure channels: Two (SC420)  
to four (SC440 & SC540) fully  
secure channels isolated to 60db.  
Safely switch between computers  
operating at different classification  
levels – without compromising  
network security.  
ƒ Clears buffer: Automatically clears  
the keyboard buffer immediately  
after data is transmitted through  
the switch, so no data is ever left  
in the switch.  
SwitchView SC420, SC440 and SC540 switching solutions provide  
three layers of tamper-proof hardware security and CAC support  
at the desktop
