directly attached to the server configuration (or local console directly attached tothe server with remote access allowed). There is a maximum of 26 emulatorsessions available per PC.v If you call a service representative to set up your new server, you must have thePC that you are going to use as a console ready to be connected to your iSeriesserver. This includes having all cables ready and all software installed. Forexample, you must already have your Windows operating system and iSeriesAccess for Windows installed on the PC.v If you are configuring Operations Console for an OS/400® partition runningLinux, see Configure the LAN console for a guest partition.Plan for your backup consoleThis topic covers backup console information you might want to consider toquickly recover from the unexpected loss of your console. Many system plansinclude a level of redundancy to allow for hardware failures, but some do notconsider the console in those plans. Here are some suggestions if you would like toplan for a backup for your console:Operations Console, both direct attached and network (LAN) and twinaxialworkstations can coexist as console devices if you remember these rules:v Only one device can be active at a time. An active console is a commandinterface to an iSeries server (5250 emulation) that is currently interacting withthe server.v A twinaxial workstation on any twinaxial work station controller with port 0(address 0 or 1 or with port 1 (address 0 or 1) can be a console device.v To prevent interactions between eligible console types, be sure you do not havemore than one workstation available during an IPL. To prevent a device enabledas an Operations Console from becoming the console, you need to disconnectany active connections and leave it disconnected during the IPL. For twinaxialworkstations, it is suggested that you power off the workstation. Note that onsome models the on/off switch actually only powers off the display portion ofthe workstation and the workstation electronics are still active, which wouldallow the device to become the console. If you are not sure, remove the powercord from the rear of the workstation.v For independent and primary partitions, multiple IOPs capable of supporting aconsole workstation can interfere with the selection of the desired LAN adapter.Consider the following:– Having a 2nd IOP on the bus before your intended console adapter card,when the first IOP contains a twinaxial adapter card, will fail to provide aLAN-connected console. For example, a model 890 uses eligible card locationsC04, and C06 through C10 and if an IOP were placed in C08 and a twinaxialadapter preceded this IOP on the bus then the LAN adapter card located atC09 or C10 will fail to provide a LAN-connected console. The LAN adaptercard must be in a location preceding the 2nd IOP, such as C06 or C07.– Typically, the card location used for Operations Console directly attachedconfigurations, commonly referred to as the ECS slot, is located close to thebeginning of the bus. When the card location is a low number such as C02,then C03 is farther from the beginning of the bus than C02. When the cardlocation is a higher number such as C07, then C06 is farther from thebeginning of the bus than C07. This may not be true for all models andexpansion units. When in doubt contact your service representative.Considerations for a backup console:8 iSeries: iSeries Access for Windows Operations Console
