IBM IntelliStation POWER 285 Technical Overview and Introduction
Table 2-6 Available Fibre Channel Adapters
2.5 System ports and serial ports
The system ports S1 and S2 at the rear of the system are only available if the system is not
managed using a Hardware Management Console (HMC). In this case, the S1 and S2 ports
support the attachment of a serial console and modem. If the system is connected to an
HMC, or additional serial ports are required, you can add one or more of the serial adapters
listed in Table 2-7.
Table 2-7 Orderable serial adapters
2.6 Internal storage
There is one dual-channel Ultra320 SCSI controller integrated into the system board that is
used to drive the internal disk drives. The four internal drives are attached to the disk drive
backplane, which has one SCSI bus with four disk drives.
The internal disk drive can be used in two different modes, based on whether the SCSI RAID
Enablement Card (FC 1907) is installed. See 2.7, “RAID options” on page 24.
The IntelliStation POWER 285 system supports one 4-pack disk drive using a backplane that
is designed for hot-pluggable disk drives. The disk-drive backplane docks directly to the
system board. The virtual SCSI enclosure services (VSES) hot-plug control functions are
provided by the Ultra320 SCSI controllers.
2.6.1 Internal media devices
The IntelliStation POWER 285 system provides two slim-line media bays for an optional
DVD-ROM and l DVD-RAM devices and one media bay for an optional tape drive, as listed in
Table 2-8 on page 22 and Table 2-9 on page 23.
