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.

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.
