Directions For Lifting The Handle On The Power - IBM Storwize V7000 Troubleshooting And Maintenance Manual

Be careful when you are replacing the hardware components that are located in the back of the system
that you do not inadvertently disturb or remove any cables that you are not instructed to remove.
Attention: In some instances, it might not be advisable to remove a power supply unit when a system
is performing I/O. For example, the charge in the backup battery might not be sufficient enough within
the partner power-supply unit to continue operations without causing a loss of access to the data. Wait
until the partner battery is 100% charged before replacing the power supply unit.
Ensure that you are aware of the procedures for handling static-sensitive devices before you replace the
power supply.
This task assumes that you are not replacing a battery in the power supply unit of the control enclosure.
To replace a battery, go to "Replacing a battery in a power supply unit" on page 96.
To replace the power supply, perform the following steps:
1. Read the safety information to which "Preparing to remove and replace parts" on page 85 refers.
2. Examine the Identify LED that is lit on the front of the enclosure to identify the correct enclosure.
3. Turn off the power to the power supply units using the switches at the back of the units.
4. Disconnect the cable retention bracket and the power cord from the power supply that you are
replacing.
5. Remove the power supply unit. Record the orientation of the power supply unit. Power supply unit
1 is top side up, and power supply unit 2 is inverted.
