FI01141 FI01141 indicates that a loss of power to an IOP, to an internal device, or to an external
device may have occurred.
1. Are 0000 xxxx, 1xxx xxxx, or A6xx 698x SRCs displayed on the control panel?
No Yes
↓ Go to “Chapter 2. Unit Reference Codes” on page 59 and use the SRC
displayed on the control panel.
2. Did the SRC that directed you to this FI code involve an externally attached device or
an IOP with an externally attached device?
No Yes
↓ Verify that there is no obvious problem with power to the device. If you
suspect a power problem with the device, go to the service information for that
external device.
3. The power supply cables or connections to internal disk units, tape units, diskette units,
or optical storage units may be the failing item.

3. To determine the location of the I/O processor card, see “Locations and Addresses” on
page 705 and find the diagram of the system unit or the expansion unit. Then, find:
v The IOP card location identified by the direct select address.
v The addressed storage device location identified by the device address.
4. Exchange the failing device. Use the device type to determine the part.
