Single-user 4-port KVM

The Compaq 400336-001 is a single-user KVM switchbox that lets one keyboard, monitor and mouse control four connected computers. It is built for server-room administrators who need local console access to multiple systems from a single rack-mounted unit. The switch supports VGA, SVGA and XGA video modes across its four system ports. Tiering two units together expands the number of systems one user can manage.

Passive operation, rack form factor

The unit draws power at 60 Hz and operates without active cooling, so it adds no fan noise to the rack environment. Its 1.7" height fits a standard 1U rack space while the 17" width and 8" depth match typical server cabinet dimensions. At 5.25 lb it is light enough for single-person installation. Power consumption stays low because the switch only routes keyboard, video and mouse signals.

PS/2 and VGA cabling included

Ten PS/2 ports and one VGA port on the rear panel provide the physical connections for four system cables and one local console cable. The bundled cables eliminate the need to source legacy PS/2 and VGA leads separately. No software or drivers are required; switching between systems is handled by front-panel buttons or keyboard hot-keys. Buyers needing USB or digital video interfaces will need a different switch.

Questions about this item

How do I install the Compaq 400336-001 KVM switch in a rack and which cables go where?

Mount the 1.7" high unit in a standard 17" rack, connect your keyboard, monitor and mouse to the single console ports, then attach up to four servers using the ten PS/2 and one VGA system ports.

What maintenance or replacement will the Compaq 400336-001 need over time?

The switch has no user-serviceable parts; plan to replace the unit if ports fail or if you migrate to USB or digital video, as it only supports PS/2 and VGA.

What limit appears first when running the Compaq 400336-001 continuously in a server room?

The 60 Hz power rating and passive cooling mean thermal limits or power stability will constrain sustained operation before port capacity does.
