I/O processor (IOP) isolation procedures
Use these procedures to isolate a failure in the multiple function
I/O card.
Please read all safety procedures before servicing the system.
Attention: Unless instructed otherwise, always power off the system
or expansion tower where the field replaceable unit (FRU) is located
before removing, exchanging, or installing a FRU.
Attention: Disconnecting the J15 and J16 cables will not prevent
the system unit from powering on.
DANGER
When working on or around the system, observe
the following precautions:
Electrical voltage and current from power, telephone,
and communication cables are hazardous. To avoid a shock hazard:
- Connect power to this unit only with the IBM provided
power cord. Do not use the IBM provided power cord
for any other product.
- Do not open or service any power supply assembly.
- Do not connect or disconnect any cables or perform installation, maintenance,
or reconfiguration of this product during an electrical storm.
- The product might be equipped with multiple power cords. To remove all
hazardous voltages, disconnect all power cords.
- Connect all power cords to a properly wired and grounded electrical outlet.
Ensure that the outlet supplies proper voltage and phase rotation according
to the system rating plate.
- Connect any equipment that will be attached to this product to properly
wired outlets.
- When possible, use one hand only to connect or disconnect signal cables.
- Never turn on any equipment when there is evidence of fire, water, or
structural damage.
- Disconnect the attached power cords, telecommunications systems, networks,
and modems before you open the device covers, unless instructed otherwise
in the installation and configuration procedures.
- Connect and disconnect cables as described in the following procedures
when installing, moving, or opening covers on this product or attached devices.
To
Disconnect:
- Turn off everything (unless instructed otherwise).
- Remove the power cords from the outlets.
- Remove the signal cables from the connectors.
- Remove all cables from the devices
To Connect:
- Turn off everything (unless instructed otherwise).
- Attach all cables to the devices.
- Attach the signal cables to the connectors.
- Attach the power cords to the outlets.
- Turn on the devices.
