MAP 152j: 2.5 V Current/Voltage Problem in I/O Subsystem

Step 152j-1
Record the error code and location code(s) that sent you to this MAP.
Step 152j-2
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
v If yy=21, I/O subsystem number is 5, location is U2.1
v If yy=22, I/O subsystem number is 6, location is U2.5
v If yy=23, I/O subsystem number is 4, location is U2.9
v If yy=24, I/O subsystem number is 7, location is U2.13
v If yy=25, I/O subsystem number is 8, location is U2.19
Step 152j-3
Turn off the power.
Examine the green "power good out" LEDs of both I/O subsystem DCAs.
Step 152j-4
Are all the green "power good out" LEDs of both I/O subsystem DCAs off?
Yes Go to "Step 152j-5".
No Call for support.
Step 152j-5
Remove the following adapter cards, if present, from the I/O subsystem. Record the adapter locations:
v Adapter card at P1-I1
v Adapter card at P1-I2
v Adapter card at P1-I3
v Adapter card at P1-I4
v Adapter card at P1-I5
Step 152j-6
Turn on the power.
Step 152j-7
Did the system stop with the same error code as recorded in "Step 152j-1"?
Yes Go to "Step 152j-13" on page 223.
No Go to "Step 152j-8" on page 223.
