Chapter 5. IBM AS/400e 720, 730, and 740 models 165
#9754 #9754 MFIOP with RAID (Ultra SCSI) CCIN 6754
The #9754 is an Ultra SCSI controller that provides unprotected, mirrored, or RAID-5 protection for internal disk units. It
includes a 4M write cache for better performance and improved device utilization. The #9754 controls the internal CD-ROM
drive and one internal tape unit. It contains three IOA slots for communications, LAN, and twinaxial I/O adapters. IOA slot
A is reserved for attaching one #2699 2-Line WAN IOA or one #6149 or #6181 LAN IOA. IOA slot B is reserved for attaching
the #9699 Base 2-Line WAN IOA. IOA slot C is reserved for attaching one #2699 2-Line WAN IOA or one #6180 or #9280
twinaxial IOA. It is occupies two card slots.
The #9754 controls Ultra, Fast Wide, and Fast Narrow SCSI disk units located in the 730 or 740 system unit, and the #5055
Storage Expansion Unit or the #5057 Storage Expansion Unit. The Ultra SCSI disks give the best performance when
attached to the #9751. The #9754 also controls disks that are not Ultra SCSI. However, in that case, the disks do not
perform at Ultra SCSI speeds.
The #9754 supports a maximum of 20 disk units, one removable tape unit, and one CD-ROM unit. A maximum of 10 disk
units per RAID-5 array is supported. Parity information can be spread across four or eight disk units. A maximum of four
RAID-5 arrays is supported on one #9754. Disk units that are not supported in a RAID-5 array can be attached to the #9754
in either an unprotected or a mirrored environment.
The #5544 System Console on Operations Console is the default for 720, 730, and 740 models. The #0328 Operations
Console Cable is used unless another console controller is specified. The #0380 Remote Control Panel Cable can be used
to support the Remote Control Panel function. The #0380 cable does not attach to a communication port.
Supported on Models 730 and 740
Minimum operating system level: OS/400 V4R2
Minimum operating system level to support integrated hardware disk compression: OS/400 V4R3

#2617 #2617 Ethernet/IEEE 802.3 Adapter/HP (SPD)
The #2617 provides a single attachment to one Carrier Sense Multiple Access/Collision Detect Local Area Network. It
consists of an adapter card and internal code, which supplies Ethernet Version 2 and IEEE 802.3 Media Access Control
(MAC) plus IEEE 802.2 Logical Link Control (LLC) functions. An AUI Ethernet cable must be ordered separately.
Supports 10 Mbps half-duplex only
SPD slots required: One
#2618 #2618 Fiber Distributed Data Interface Adapterr (SPD)
The #2618 provides one interface to connect an iSeries or AS/400e to an FDDI LAN which complies with ANSI X3T9.5
and ISO 9314 standards. It consists of a card, a wrap connector, and Licensed Internal Code, which supplies IEEE 802.2
LLC, ANSI X3T9.5/ISO 9314 MAC functions, and ANSI X3T9.5 Station Management (SMT) functions. A multi-node
(62.5/125 micron) FDDI optical fiber jumper cable to connect the adapter to the FDDI ring must be ordered separately.
SPD slots required: One
#2619 #2619 LAN/WAN/Workstation IOA (SPD)
The #2619 provides a single attachment to a 16 Mbps or a 4 Mbps Token Ring Network. It consists of an adapter card,
internal code (supplies IEEE 802.5 MAC and IEEE 802.2 LLC functions), and an external 8-ft (2.4 m) cable.
SPD slots required: One
#2626 #2626 16/4 Mbps Token Ring Adapter/A (SPD)
The #2626 provides a single attachment to a 16 Mbps or a 4 Mbps Token Ring Network. It consists of an adapter card,
internal code (supplies IEEE 802.5 MAC and IEEE 802.2 LLC functions), and an external 8-ft (2.4 m) cable.
SPD slots required: One
#2629 #2629 LAN/WAN/Workstation IOP (SPD)
The #2629 supports up to three LAN/WAN/ Workstation IOAs. See the full description of the #2629 in “Workstation
controllers” on page 154.
The #2629 was withdrawn from marketing on 31 May 2001.
