Plan for your backup console

This topic covers backup console information you might want to consider to
quickly recover from the unexpected loss of your console. Many system plans
include a level of redundancy to allow for hardware failures, but some do not
consider the console in those plans. Here are some suggestions if you would like to
plan for a backup for your console:
Operations Console, both direct attached and network (LAN) and twinaxial
workstations 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 command
v A twinaxial workstation on any twinaxial work station controller with port 0
v To prevent interactions between eligible console types, be sure you do not have

more than one workstation available during an IPL. To prevent a device enabled
as an Operations Console from becoming the console, you need to disconnect
any active connections and leave it disconnected during the IPL. For twinaxial
workstations, it is suggested that you power off the workstation. Note that on
some models the on/off switch actually only powers off the display portion of
the workstation and the workstation electronics are still active, which would
allow the device to become the console. If you are not sure, remove the power
cord from the rear of the workstation.
console 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 a
LAN-connected console. For example, a model 890 uses eligible card locations
C04, and C06 through C10 and if an IOP were placed in C08 and a twinaxial
adapter preceded this IOP on the bus then the LAN adapter card located at
C09 or C10 will fail to provide a LAN-connected console. The LAN adapter
card must be in a location preceding the 2nd IOP, such as C06 or C07.
– Typically, the card location used for Operations Console directly attached
configurations, commonly referred to as the ECS slot, is located close to the
beginning 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 card
location is a higher number such as C07, then C06 is farther from the
beginning of the bus than C07. This may not be true for all models and
expansion units. When in doubt contact your service representative.
