I/O Adapters and Controllers
302 iSeries Handbook
In addition, this internal modem provides the ability for IBM to provide remote support over a
dial-up connection.
PM/400 and Electronic Service Agent for AS/400 over TCP/IP is available. These applications
are also enabled over the Universal Connection. In addition, the ability to inventory multiple
systems hardware and software information is provided. This is done by consolidating
multiple systems onto one Management Central system prior to transmission over this
connection. For additional information, see:

Fax is supported on the V.90 port with V5R1.
ECS also operates on the WAN port of the #9771 by changing the *RSRCNAME parameter of
the QESLINE and QTILINE line descriptions to that of the WAN port on the #9771 card.
When the #9771 is selected to support ECS, specify one of these cables for connection to the
WAN port:
• #0348 V.24/EIA232 20-ft PCI cable (the default)
• #0349 V.24/EIA232 50-ft PCI cable
• #0365 V.24/EIA232 80-ft PCI cable
The #9771 now supports the Operations Console as a system console. Remote power-on is
not supported.
#2763 PCI RAID Disk Unit Controller
The #2763 is an Ultra2 SCSI disk unit controller with a 10 MB write-cache that provides
RAID-5 protection for internal disk units and also supports internal tape and CD-ROM units.
In addition to providing RAID-5 protection for disks, the #2763 is also designed to work as a
high-performance controller for disks protected by system mirroring or disks with no
protection. In the RAID-5 configuration, disk unit protection is provided at a lower cost than
mirroring and with greater performance than system checksums.
The #2763 controller supports a maximum of 12 disk units and up to two removable media
devices and is available on the Model 270, the Model 820, and the #5075 PCI Expansion
Tower.
A minimum of four drives of the same capacity are needed for a valid RAID-5 configuration. A
maximum of three arrays are allowed, with a maximum of 10 drives allowed per array. All
drives in an array must be of the same capacity.
The #2763 feature is hot pluggable.
