Know your IBM warranty and maintenance agreement details
If you have a warranty or maintenance agreement with IBM, know the details that
must be supplied when you call for support.
Have the phone number of the support center available. When you call support,
provide the machine type and the serial number of the enclosure or file module
that has the problem. The machine type is always 2076 for a control enclosure or
2073 for a file module. If the problem does not relate to a specific enclosure,
provide the control enclosure serial number. The serial numbers are on the labels
on the enclosures.
Support personnel also ask for your customer number, machine location, contact
details, and the details of the problem.
