The ATEN KH2508A KVM switch enables control of up to 8 computers from a single keyboard, mouse and monitor setup. It supports both USB and PS/2 keyboard and mouse connections and provides VGA video output with maximum resolution support up to 1600 x 1200@60Hz (with KA7000 series adapter cables). The compact switch weighs 2.81 kg, consumes 8.6 W and is suitable for rack mounting in server rooms or workspaces where centralized control of multiple systems is required.

Advantages

The KH2508A supports two independent KVM consoles that can simultaneously control the connected computers, and it can be daisy-chained with up to 15 additional KH2508A units to manage as many as 128 systems from the original console. It provides mixed PS/2 and USB compatibility on both console and computer sides, configurable per-port access rights, three port operation modes (Occupy, Exclusive, Share), multi-language OSD, hotkey and front-panel control, as well as auto-scan and broadcast modes. Security features include two-level password protection with one administrator and up to ten user accounts. The unit’s firmware is upgradeable and it supports PC, Mac, Sun and serial platforms.

How to use

Install the KH2508A in a rack or place it on a stable surface and connect each target computer using compatible KVM adapter cables (KA7000 series recommended for optimal video). Attach keyboard, mouse and monitor to the KVM console ports (USB or PS/2 as required). Use front-panel buttons, hotkeys or the on-screen display (OSD) to switch between computers. Configure user accounts and per-port access rights through the OSD and perform firmware updates via the provided upgrade cable when needed. For larger deployments, daisy-chain up to 15 additional KH2508A units to expand control to up to 128 systems.

Recommendations

Use KA7000-series KVM adapter cables to achieve the specified maximum video resolutions, and configure account and port permissions before placing the switch into production. When chaining multiple units, verify cable lengths and signal quality to maintain reliable video and input response.
