The ZT 5504 requires 5V V(I/O) to operate as a system master. It supports either 3.3V or 5V
V(I/O) in drone mode. It will not correctly terminate the PCI bus if used in a system slot
configured for 3.3V V(I/O). For this reason, Intel ships the ZT 5504 with a blue key in
CompactPCI connector J1, which prevents the ZT 5504 from being installed in any slot
configured for 3.3V V(I/O).
For the ZT 5504 to be used in drone mode in a peripheral or non-bused slot configured for 3.3V
V(I/O), the key must be removed from J1. The ZT 5504 with the key removed can be used
without damage in a system slot configured for 3.3V V(I/O), but the PCI bus will not operate
correctly. The following table shows ZT 5504 V(I/O) functionality:
