iSeries Model 840186 iSeries Handbook• X.21 switched WAN dial-up or Shorthold Mode WAN• Asynchronous communication speeds of less than 300 bps• Data Rate Select signal on the EIA 232/V.24 interface. This function is used by someolder 2400 bps modems to reduce the speed to 1200 bps.• LPDA-1 (Link Problem Determination Aids). This is a diagnostic function supported bysome (primarily older IBM) modems.• V.54 local and remote loopback (diagnostics functions supported by some modems)PCI adapters also do not support X.21 switched WAN dial-up or Shorthold Mode WAN.The fundamental bus architecture of the iSeries is unchanged when using PCI adapters. TheAS/400e IOP continues to off load the main processor; isolate the host from adapter andnetwork errors; and manage, configure, and service the adapters. PCI architecture offersadvantages in flexibility over non-iSeries or non-AS/400e server structures.Processor Features• #2352 8/12-way Processor on Demand (POD) (SStar 600 Mhz)– Processor Capacity Card (CCIN 2352)– Processor 0 (CCIN 246F)– Processor 1 (CCIN 246E)• #2353 12/18-way Processor on Demand (POD) (SStar 600 Mhz)– Processor Capacity Card (CCIN 2353)– Processor 0 (CCIN 246F)– Processor 1 (CCIN 246E)– Processor 2 (CCIN 246E)• #2354 18/24-way Processor on Demand (POD) (SStar 600 Mhz)– Processor Capacity Card (CCIN 2354)– Processor 0 (CCIN 246F)– Processor 1 (CCIN 246E)– Processor 2 (CCIN 246E)– Processor 3 (CCIN 246E)• #2461 24-way Processor (SStar 600 Mhz)– Processor 0 (CCIN 246F)– Processor 1 (CCIN 246E)– Processor 2 (CCIN 246E)– Processor 3 (CCIN 246E)– Processor Capacity Card (CCIN 2461)
