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:
1. Turn off everything (unless instructed otherwise).
2. Remove the power cords from the outlets.
3. Remove the signal cables from the connectors.
4. Remove all cables from the devices
To Connect:
1. Turn off everything (unless instructed otherwise).
2. Attach all cables to the devices.
3. Attach the signal cables to the connectors.
4. Attach the power cords to the outlets.
5. Turn on the devices.

Is the SRC 1xxx-8700 or 8701?
- No: Return to the Start of call procedure. This ends the procedure.
- Yes: Continue with the next step.
In this step you will be measuring voltages on one of the bulk power assemblies (BPAs). If the SRC is 1xxx8700, then you should measure the voltage on BPA-A (front). If the SRC is 1xxx8701, then you should measure the voltage on BPA-B (rear).
Using the labeled test points on the face of the BPA, measure the voltages between the following:
- phase A and phase B
- phase B and phase C
- phase C and phase A
Are all of the meter readings greater than 180 V ac?
- Yes: Go to step 4.
- No: Inform the customer that power voltage at the input to the BPA could be missing or too low and needs to be checked. Continue with the next step once the check has been performed.
Does the check confirm that the customer's voltage levels missing or too low?
- Yes: The customer must correct the voltage levels. This ends the procedure.
- No: Replace the power cord (see Cables for the proper part number). This ends the procedure.
Exchange the following FRUs, one at a time, until the problem is resolved. Go to Locations — model 575 or Locations — model 590 and 595 to locate and replace the part.
1. Bulk power regulator (BPR) 1
2. BPR 2
3. BPR 3
4. Bulk power controller (BPC)
5. Bulk power assembly (BPA)
This ends the procedure.
