8.2.6 IBM Network Terminal Accelerator adapter (F/C 2402 & 2403)
The IBM Network Terminal Accelerator adapter (F/C 2402) is an Ethernet
adapter that accelerates network performance by off-loading the telnet and rlogin
daemons, TCP/IP protocol stack and virtual terminal I/O management from the
RS/6000 system. The network adapter buffers the system from frequent CPU
intensive packet interrupts, increases terminal I/O throughput and the number of
concurrent online user sessions, and reduces context switches, which
dramatically reduces the CPU load.
The network adapter software provides a pass-through capability for other
Ethernet protocols, which can eliminate the need for a separate Ethernet
adapter. The network adapter supports on board simple network management
protocol (SNMP) for network management.
8.2.7 SCSI-2 Fast/Wide adapter/A (F/C 2416)
The SCSI-2 Differential Fast/Wide adapter (F/C 2416) is a dual-ported fast (10
MHz) and wide (two bytes) adapter. It provides synchronous SCSI bus rates up
to 20 Mbps and attaches to SCSI fixed disks, CD-ROM devices, tape drives, R/W
optical devices, and storage subsystems. The maximum data rate depends on
the maximum rate of the attached device.
8.2.8 SCSI-2 Differential External I/O Controller (F/C 2420)
The SCSI-2 Differential External I/O Controller feature (F/C 2420) allows you to
attach external SCSI-2 differential devices. This adapter provides SCSI bus
signal cable quality and a maximum SCSI bus length of up to 19 meters (62.3
feet).
8.2.9 8-Port Async adapter - EIA-422A (F/C 2940)
The 8-port Async feature (F/C 2940) provides the RS/6000 500 series system
with up to eight EIA-422A asynchronous serial devices such as terminals and
printers. The 8-port Async adapter contains all of the electronics required to
support eight asynchronous ports and uses one I/O card slot.
8.2.10 SYSKONNECT SK-NET FDDI adapters (F/C 2741, 2742 & 2743)
There are three types of SYSKONNECT SK-NET FDDI adapters they include:
LP Single Attach Station (SAS) feature code - 2741
LP Dual Attach Station (DAS) feature code - 2742
UP Dual Attach Station (DAS) feature code - 2743
