Restrictions
(cont.)
Not allowed on the #2720/#9720 if this combination of adapters is installed on the base MFIOP:
– #2722 or #2746 plus one #2723 or #2724
No more than seven #2629s can be placed into each #5072 1063 Mbps System Unit Expansion Tower.
Bisync is always limited to a maximum of 64 Kbps.
Additional restrictions include:
V.25 autocall cable is not supported.
Select standby mode is not supported.
#2750, #2751, #2761, #4750, #4751, #4761 are not supported after OS/400 V5R2.
#2817, #481x #28x ATM not supported. Upgrade to Ethernet.
Notes:
It is imperative that these restrictions be understood and followed. If they are not followed, it is possible that a
hardware configuration could be built that marginally works, and later quits working when the machine is upgraded to
future software releases.
For best performance, we recommend that no other features be intermixed with a #2838 PCI 100/10 Mbps Ethernet
IOA or a #2811, #2812, #2815, #2816, #2818, or #2819 ATM IOA on a #2809 PCI LAN/WAN/Workstation IOP.
The quantity and speed of each communications line must be known. Complete this table to determine the total
communications CPW required. The #2750, #2751, and #2761 count as eight low-speed communications lines.

#2742 #2742 2-Line WAN IOA
The #2742 2-Line WAN IOA is a WAN IOA that supports up to two multiple protocol communications (RVX) ports when
one or two (in any combination) of the following cables are attached. Select one of the following cables to attach to port 1
or 2 (RVX port):
#0348 V.24/EIA232 20-ft. (6 m) PCI cable
#0349 V.24/EIA232 50-ft. (15 m) PCI cable
#0353 V.35 20-ft PCI cable
#0354 V.35 50-ft PCI cable
#0355 V.35 80-ft/24 m PCI cable
#0356 V.36 20-ft PCI cable
#0358 V.36 150-ft/45 m PCI cable
#0359 X.21 20-ft PCI cable
#0360 X.21 50-ft PCI cable
#0365 V.24/EIA232 80-ft PCI cable
#0367 Operations Console PCI Cable
The #0367 cable ships with a 25-pin to 9-pin adapter. Multiple #0367 cables can be ordered (but only one per #2742) to
serve as consoles for secondary partitions when #0140 Logical Partitioning Specify is ordered.
When the #2742 is selected to support ECS, one of following cables must be specified:
#0348 V.24/EIA232 20-ft. (6 m) PCI cable
#0349 V.24/EIA232 50-ft. (15 m) PCI cable
#0367 Operations Console PCI Cable
The #2742 does not support Remote Power On.
Minimum operating system level: OS/400 V5R2
The #2742 is a Customer Install Feature.
