What To Do Next
If any of your LinkBuilder MSH equipment fails to operate
correctly, contact your supplier with the following information
before returning the equipment:
Serial Number
Revision Number
A brief description of the fault
For modules, the Serial Number and Revision Number are printed
on the circuit board. The reference guides that accompany these
modules show the location of these numbers. For the LinkBuilder
MSH chassis, both numbers are on a label attached to one of its
sides.
When returning equipment to your supplier make sure it is
suitably packed for transit. When returning the LinkBuilder MSH
chassis, remove all modules.
Please make sure that you have carried out the recommended
checks and observations in the rest of this chapter.
