System Overview 1-3
Your server may include a non-redundant non-hot-swap power supply or redundant hot-
swap power supply module containing up to two power supply units (see Figure 1-3).
Your server may also include a non-hot-swap SCSI hard disk drive cage or hot-swap
SCSI hard disk drive cage (see Figure 1-4). The non-hot-swap SCSI hard disk drive
cage supports five 1-inch SCSI hard disk drives. The hot-swap SCSI hard disk drive
cage holds up to five 1.0-inch SCSI hard disk drives that can be swapped in or out of
the system without powering it down, if RAID is configured in the system. For hot-
swap redundant system models only, an additional five-disk hot-swap hard disk drive
cage is also available. This cage comes with five hard disk drive carriers and cables for
internal connection.
