Workstation adapter isolation procedure
Isolates a failure that is detected by the workstation adapter, and is used when no display is available with which to perform on-line problem analysis.
The workstation adapter detected a problem while communicating with the workstation that is used as the primary console.
Note: If you are using a PC, you must install an emulation program.
Read and observe all safety procedures before servicing the system and while performing the procedure below.
Attention: Unless instructed otherwise, always power off
the system or expansion unit where the FRU is located (see Powering on and powering off the system)
before removing, exchanging, or installing a field-replaceable unit
(FRU).
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:
- If IBM supplied the power cord(s), 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.
- For AC power, disconnect all power cords from their AC power source.
- For racks with a DC power distribution panel (PDP), disconnect the customer’s DC power source to the PDP.
- When connecting power to the product ensure all power cables are properly connected.
- For racks with AC power, 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.
- For racks with a DC power distribution panel (PDP), connect the customer’s DC power source to the PDP. Ensure that the proper polarity is used when attaching the DC power and DC power return wiring.
- 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.
- Do not attempt to switch on power to the machine until all possible unsafe conditions are corrected.
- Assume that an electrical safety hazard is present. Perform all continuity, grounding, and power checks specified during the subsystem installation procedures to ensure that the machine meets safety requirements.
- Do not continue with the inspection if any unsafe conditions are present.
- Before you open the device covers, unless instructed otherwise in the installation and configuration procedures: Disconnect the attached AC power cords, turn off the applicable circuit breakers located in the rack power distribution panel (PDP), and disconnect any telecommunications systems, networks, and modems.
DANGER
- Connect and disconnect cables as described in the following procedures when installing, moving,
or opening covers on this product or attached devices. To Disconnect:To Connect:
- Turn off everything (unless instructed otherwise).
- For AC power, remove the power cords from the outlets.
- For racks with a DC power distribution panel (PDP), turn off the circuit breakers located in the PDP and remove the power from the Customer's DC power source.
- Remove the signal cables from the connectors.
- Remove all cables from the devices.
- Turn off everything (unless instructed otherwise).
- Attach all cables to the devices.
- Attach the signal cables to the connectors.
- For AC power, attach the power cords to the outlets.
- For racks with a DC power distribution panel (PDP), restore the power from the Customer's DC power source and turn on the circuit breakers located in the PDP.
- Turn on the devices.
