What this KVM switch does

The ATEN KH2508A is an 8-port CAT5 KVM switch that lets two operators independently control up to eight servers from separate PS/2 or USB consoles. Daisy-chaining supports up to 31 additional units for larger installations.

Before you order

Verify that each target server provides keyboard, mouse and video connections compatible with the switch’s RJ-45 CAT5 interface. Ensure you have CAT5 cables for every server link and that the consoles use USB Type A or 6-pin Mini-DIN for keyboard and mouse plus HDB-15 for video. Confirm the 1600 x 1200 @ 60 Hz resolution meets your display requirements.

Who this suits and who it does not

Suited for server-room administrators who need simultaneous dual-console access to eight rack-mounted systems with room to expand. Not suited for buyers who need more than two independent consoles, who require single-port desktop switching, or who need video resolutions beyond 1600 x 1200.

Questions about this item

What cables and accessories are included, and which ones must I buy separately to connect eight computers?

The box contains the KH2508A switch, a power cord, grounding wire, firmware upgrade cable, rack-mount kit, four foot pads, a user manual and a quick-start guide. You must purchase eight CAT5 KVM dongles or CAT5 cables with RJ-45 ends to link each computer to the switch's eight RJ-45 ports.

The KH2508A supports eight ports; when would I choose the 16-port KH2516A instead?

Choose the KH2516A when you need to control up to 16 directly connected computers from the same two consoles. Both models can be daisy-chained with up to 31 additional units, expanding total capacity to 256 or 512 servers respectively.

What does the 1600 x 1200 resolution spec mean for my monitors in daily use?

Each console can display up to 1600 x 1200 at 60 Hz, so VGA monitors connected to the two HDB-15 ports will show sharp, flicker-free images at that resolution without scaling artefacts.
