The component will not be serviced concurrently. Power should be removed from the unit containing the FRU in the location field above. If this unit is powered on, power it off now. When the unit is completely powered off, disconnect the AC input source by removing the power cord from the unit. Do not apply power to the unit until directed to do so in this procedure.

Remove the front cover

1. Unlock the cover.
2. Open the cover by grasping its right side (A) and pulling it towards you.
