IBM AS/400e

AS/400e server 820
148 AS/400e System Handbook
• Asynchronous communication speeds of less than 300 bps
• Data Rate Select signal on the EIA 232/V.24 interface. This function is used by some
older 2400 bps modems to reduce the speed to 1200 bps.
• LPDA-1 (Link Problem Determination Aids). This is a diagnostic function supported by
some (primarily older IBM) modems.
• V.54 local and remote loopback (diagnostics functions supported by some modems)
The fundamental bus architecture of the AS/400 system is unchanged when using PCI
adapters. The AS/400 IOP continues to off load the main processor; isolate the host from the
adapter and network errors; and manage, configure, and service the adapters. PCI
architecture offers advantages in flexibility over non-AS/400 system structures.
Processor Features
#2395 Model 820 Processor (PULSAR Uni)
• Includes eight DIMM memory positions (which plug directly onto the backplane - Direct
Attach)
• Includes Base I/O Backplane with Common Service Processor (CSP) (CCIN 284C)
Provides support for the Service Processor, nine 32-bit and three 32- or 64-bit PCI slots.
#2396 Model 820 Processor (PULSAR Uni)
• Includes eight DIMM memory positions (which plug directly onto the backplane - Direct
Attach). If more than eight DIMMs total are required, a #2884 Main Storage Expansion
Card must be used and
all DIMMs must then reside on the #2884.
• Includes Base I/O Backplane with Common Service Processor (CSP) (CCIN 284C)
Provides support for the Service Processor, nine 32-bit and three 32- or 64-bit PCI slots.
#2397 Model 820 Processor (IStar 2-way)
• Includes 16 DIMM memory positions with the base main storage expansion card
(CCIN 2884)
• Includes Base I/O Backplane with Common Service Processor (CSP) (CCIN 284C)
Provides support for the Service Processor, nine 32-bit and three 32- or 64-bit PCI slots.
#2398 Model 820 Processor (IStar 4-Way)
• Includes 16 DIMM memory positions with the base main storage expansion card
(CCIN 2884).
