MAP 152n: DASD Subsystem Power Problem
Step 152n-1
Record the error code and location code(s) that sent you to this MAP.
Step 152n-2
Press the green
start service
button on the panel with the UEPO switch.
Determine the I/O subsystem number from the error code (10yy xxxx) and the following list. The remaining
steps of this map refer to this I/O subsystem:
v
If yy=14, I/O subsystem number is 1, location is U1.9
v
If yy=15, I/O subsystem number is 2, location is U1.5
v
If yy=16, I/O subsystem number is 3, location is U1.1
v
If yy=17, I/O subsystem number is 4, location is U1.13
Step 152n-3
Examine the last 2 characters of the error code recorded in “Step 152n-1”, and use the following list to
determine which DASD backplane to service.
v
If the last 2 characters of the error code is 96, then the following steps refer to DASD backplane 1 of
I/O subsystem number found in “Step 152n-2”.
v
If the last 2 characters of the error code is A6, then the following steps refer to DASD backplane 2 of
I/O subsystem number found in “Step 152n-2”.
v
If the last 2 characters of the error code is B6, then the following steps refer to DASD backplane 3 of
I/O subsystem number found in “Step 152n-2”.
v
If the last 2 characters of the error code is C6, then the following steps refer to DASD backplane 4 of
I/O subsystem number found in “Step 152n-2”.
Step 152n-4
Turn off the power. Examine the green
″
power good out
″
LEDs of both I/O subsystem DCAs.
Step 152n-5
Are all the green
″
power good out
″
LEDs of both I/O subsystem DCAs off?
Yes
Go to “Step 152n-6” on page 251.
No
Call for support.
