SOLUTION: Check cable connections on each CPU and the switch. Verify that keyboard, video, and mouse connect from each CPU to matching ports. After reconnecting, the CPU may need to be re-booted in order to sense the monitor connection.

PROBLEM: No Mouse Movement

SOLUTION: Check cable connections on each CPU and the switch. Verify that keyboard, video, and mouse connect from each CPU to matching ports. Verify that the mouse driver was loaded.

PROBLEM: No Keyboard Activity after running shutdown program on IBM PowerServer 220

SOLUTION: 1. Select a different port from the front panel buttons.

2.Turn power OFF to PowerServer 220. (either step above will enable keyboard)

PROBLEM: Monitor shuts down while working with OSD menu

SOLUTION: Disengage or increase time setting of CPU’s monitor “sleep” mode from the BIOS and/or control panel display settings. (The CPU does not sense activity while in the OSD menu )
