Installation Overview
Figure 1-7 illustrates the service side of an I/O enclosure that has a power shelf. The
power shelf has two DC power supplies that furnish power to the IOMF 2 CRUs in slots
50 and 55.
The IOMF 2 CRU offers more connectivity options than the IOMF CRU. On the IOMF 2
CRU, the external SCSI port accepts the SCSI SAC used on PMF 2 and
ServerNet/DAs for connecting tape devices. The ServerNet port accepts serial-copper
and single-mode fiber-optic cables in addition to ECL cables.
