v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v If an action step is preceded by "(Trained technician only)", that step must be performed only by a trained
technician.
v Go to the IBM support website at http://www.ibm.com/supportportal to check for technical information, hints,
tips, and new device drivers or to submit a request for information.
