Setup
- Power Off Devices: Ensure both the server and the KVM switch are powered off before making any connections.
- Connect to Server: Locate the VGA output port and an available USB port on your server. Connect the corresponding VGA (HD-15 male) and USB (Type-A male) connectors of the EHN9000U-0006 cable to these ports on the server.
- Connect to KVM Switch: Locate the KVM port on your KVM switch designated for the server. Connect the combined VGA (HD-15 female) and USB (Type-A female) end of the EHN9000U-0006 cable to the KVM switch's input port. Ensure a secure fit for both connectors.
- Power On: Once all connections are secure, power on the KVM switch, then power on the server.
Operating
Once the cable is properly connected and devices are powered on, the KVM switch should detect the connected server. Use the KVM switch's controls (buttons, hotkeys, or OSD) to switch to the server connected via this cable. You should then have control over the server's video, keyboard, and mouse.
- Refer to your KVM switch's user manual for specific instructions on switching between connected servers.
- Ensure the KVM switch is configured to recognize the USB keyboard and mouse signals.
Maintenance
The Black Box SERVSWITCH EC USB Server Cable requires minimal maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Do not use liquid cleaners or solvents.
- Storage: When not in use, store the cable in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tight coiling to prevent internal damage.
- Handling: Always grasp the connector housing when plugging or unplugging the cable. Avoid pulling on the cable itself.
