Light Path Diagnostics Panel - IBM 8841 - eServer xSeries 236 Option Installation Manual

Light path diagnostics panel

The following illustration shows the remind button and the LEDs on the light path
diagnostics panel. The light path diagnostics panel is inside the server under the
left-side cover and the error LEDs are also visible through the left-side cover.
Use the remind button on the light path diagnostic panel to acknowledge that an
error has occurred without taking further action. When you push the remind button,
the system error LED will flash every 2 seconds until the error is fixed. If another
error occurs, the system error LED will then stop flashing and return to a solid on
state.
For more information about light path diagnostics, see the Hardware Maintenance
Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.
