Removing and replacing a power supply: 2145-12F or 2145-24F

You can replace either of the two hot-swap redundant power supplies in a SAN Volume Controller 2145-12F or 2145-24F expansion enclosure. These redundant power supplies operate in parallel; if one power supply fails, the other continues to power the canisters.

Before you begin

Attention:

  • Although many components are hot-swappable, they are intended to be used only when the component is not active (no I/O operations). If your system is powered on and processing I/O operations, go to the management GUI and follow the fix procedures. Initiating the replacement actions without the assistance of the fix procedures can result in loss of data or loss of access to data.

  • Be careful when you are replacing the hardware components that are located in the back of the system. Do not inadvertently disturb or remove any cables that you are not instructed to remove.

  • Ensure that you are aware of the procedures for handling static-sensitive devices before you replace the power supply.
  • Do not remove a power supply unit from an active enclosure until a replacement power supply unit is ready to be installed. While a power supply unit is not installed, airflow through the enclosure is reduced and the enclosure can overheat. Replace the power supply within 5 minutes of replacing a faulty unit. Ensure that you read and understand these instructions, and have the replacement available and unpacked before you remove the existing power supply.

About this task

Procedure

  1. Read the safety information that is described in Preparing to remove and replace parts.

Removing the power supply

  1. Confirm that you know which power supply to replace.
  2. Disconnect the power cord from the electrical outlet and the power supply that you are replacing.
  3. On the left side of the power supply, carefully press the orange release tab to the right (no more than 6 mm [0.25 in]) as you rotate the handle downward.
  4. Using the handle, gently slide the power supply out of the expansion enclosure, as shown in Figure 1.

Replacing the power supply

  1. Hold the new power supply so that the handle is fully extended.
  2. Gently slide the power supply into the enclosure until it stops. Rotate the handle upward into the closed position until it clicks.
  3. Connect the power cord to the power supply and to a properly grounded electrical outlet.
    Note: After the power cord is connected to the electrical outlet, make sure that the AC and DC power (green) LEDs are lit and the fault (amber) LED is off.
