Twsc-Pip1 - IBM iSeries Series Hardware Problem Analysis And Isolation

v Determining a Primary or Alternative Console in the iSeries
TWSC-PIP1: The workstation IOP detected an error. Read the Danger notices above before performing
this procedure.
One of the following occurred:
v All of the workstations on one port are not working.
v All of the workstations on the system are not working.
v One of the workstations on the system is not working.
v The reference code table instructed you to perform this procedure.
v The Remote Operations Console is not working.
1. If you are using a Remote Operations Console, perform "Operations Console-PIP2" on page 149
before using this procedure.
2. If the system has logical partitions, perform this procedure from the logical partition that reported the
problem. To determine if the system has logical partitions, go to Determine if the system has logical
partitions, before continuing with this procedure.
3. Are you using a workstation adapter console?
Note: A personal computer (used as a console) that is attached to the system by using a console
cable feature is known as a workstation adapter console. The cable (part number 46G0450,
46G0479, or 44H7504) connects the serial port on the personal computer to a communications I/O
adapter on the system.
v No: Continue with the next step.
v Yes: Go to "WSAC-PIP1" on page 248.
This ends the procedure.
4. Is the device you are attempting to repair a personal computer (PC)?
v No: Continue with the next step.
v Yes: PC emulation programs operate and report system-to-PC communications problems
differently. See the PC emulation information for details on error identification. Then, continue with
the next step.
5. Perform the following:
a. Verify that all the devices you are attempting to repair, the primary console, and any alternative
consoles are powered on.
b. Verify that the all the devices you are attempting to repair, the primary console, and any
alternative consoles have an available status. For more information on displaying the device
status, see Hardware Service Manager in the iSeries
c. Verify that the workstation addresses of all workstations on the failing port are correct. Each
workstation on the port must have a separate address, from 0 through 6. See the workstation
service information for details on how to check addresses.
d. Verify that the last workstation on the failing port is terminated. All other workstations on that port
must not be terminated.
e. Ensure that the cables that are attached to the device or devices are tight and are not visibly
damaged.
f. If there were any cable changes, check them carefully.
g. If all of the workstations on the system are not working, disconnect them by terminating at the
console.
h. Verify the device operation (see the device information for instructions).
i. The cursor position can assist in problem analysis.
