Locating the RID Number
The repair identification (RID) number enables the IBM customer service
coordinator to perform an entitlement check to determine the warranty or service
option that is in effect.
Locate the machine type and repair identification (RID) number of the failing unit.
The RID number is in the following locations:
• Just above the power cord on the back of the base
• On the cartridge. Apply the RID label that is shipped with the 3708 to the
cartridge when the 3708 first arrives.
• In the vital product data storage area on the logic board of the 3708 base. The
RID number is displayed on the 3708 logon screens when logging on to the
3708.
Generally, the RID number located on the cartridge and the base is the same as the
RID number displayed on the 3708 logon screens. If they are not (they will differ if
you have exchanged the base element), use the control terminal to enter the RID
number located on the base (and cartridge) into the 3708's vital product area
(EEPROM). EEPROM is a nonvolatile logic circuit in the 3708 that retains
information regardless of whether the 3708 power is on or off.
Maintaining the same RID number on the base, the cartridge, and within the 3708's
vital product area ensures smoother and faster service if you need to exchange 3708
elements or need remote service for microcode.
