Secure 4-port KVM for classified work
The Black Box SS4P-SH-DP-UCAC is a NIAP 3.0 certified KVM switch that lets one operator control four DisplayPort computers from a single keyboard, mouse and monitor. It is built for defence, intelligence and government agencies where data separation between classification levels is mandatory. The switch isolates every port mechanically, electrically and optically to prevent any signal leakage.
Sustained isolation under continuous switching
Each channel enforces uni-directional data flow from computer to peripheral, so no peripheral can inject data back into a secure host. Protected firmware blocks unauthorised reprogramming or read-out, while keyboard and internal cache wiping clears residual keystrokes after every session. Chassis intrusion detection and tamper-evident seals provide physical evidence if the unit is opened.
Low-profile desktop thermals with no active cooling
The unit operates without fans, drawing power only for signal conditioning and secure microcontroller functions. Silent operation suits quiet command centres and office environments alike. External power supply keeps heat away from the switching fabric, maintaining stable performance during extended watch cycles.

Questions about this item
Does the SS4P-SH-DP-UCAC generate noticeable fan noise or heat when left on continuously?
The unit has no internal fan and relies on passive cooling, so it runs silently and stays cool during all-day operation.
Which peripherals and cables must I already have to connect four computers to this switch?
You need four DisplayPort cables for video, four USB cables for keyboard and mouse, one DisplayPort cable for the monitor, and a USB keyboard and mouse set.
Will the switch work reliably with older DisplayPort 1.1 or 1.2 sources that I still use?
Yes, the DisplayPort interface is backward compatible, so legacy 1.1 and 1.2 computers connect and switch without extra configuration.
