Replacing a hot-swap power supply Before replacing a power supply, read the following important information: v The power supply does not require preventive maintenance. v The unit must be installed in the correct place to maintain proper expansion unit cooling. v Use only power supplies that are supported for your specific storage subsystem. Complete the following steps to replace a hot-swap power supply: 1. Read the safety information beginning on page iii and "Installation guidelines" on page 35. 2. Turn off the power supply. 3. Disconnect the power cord from the electrical outlet and from the power supply. 4. Remove the power supply from the storage subsystem: a.
