Avocent SCKM140 Secure 4-Port Desktop KVM with Audio (End-of-Life) Review
Avocent SCKM140 secure 4 port desktop KVM audio VGA end of life discontinued legacy classified NIAP
The SCKM140 was Avocent's long-running 4-port secure desktop KVM with audio switching, and it's now end-of-life — remaining stock is discounted accordingly. It's still a legitimate option for agencies extending an existing SCKM140 deployment who need drop-in matching units, but new secure-KVM buys should look at its direct successor.
End-of-Life, Not End-of-Support
Avocent has stopped production of the SCKM140, and this listing reflects remaining channel inventory at a reduced price. It remains fully functional and NIAP-legacy evaluated, making it suitable for fleet consistency in facilities that already standardized on it.
Audio Switching Included
Unlike many pure-data secure KVMs, the SCKM140 switches stereo audio alongside VGA video and USB peripherals, useful for classified desks running voice or alert audio per network.
Comparison to Alternatives
Its direct successor, the Avocent Cybex Secure SCKM140PP4-400, adds current PP4.0 certification and a lower street price even before EOL discounting, and is the recommended path for any new deployment. The Vertiv Avocent SwitchView SC920 covers only 2 ports at a similar price point for smaller desks.
