The IDC has four universal slots and two dedicated slots. The IDCe has six universal
slots, three restricted slots and 4 dedicated slots. A populated IDC/IDCe is called an
INU/INUe.
Figure 6-7. Slot Numbering for INU and INUe
Installing or changing out a plug-in is a straightforward process. The requirements are
detailed in Table 6-2.
Unless specified by the customer, plug-ins will not be installed in an INU/INUe at
shipment. Instead, each is individually packed within the shipping box.
