Power Module Replacement Procedure
CAUTION! The power module is hot pluggable only if a second power module is present and operating. If you remove the only power module in the storage system, the storage system and all modules will lose power.
NOTE! If there are two power modules in the storage system, each will share the power load. If one power module fails or is removed, or if one of the ac power cords is removed, the other power module will take over the entire power load without interruption.
NOTE! You can replace a power module while the host and the storage system are operating.
To replace a power module:
1.Remove the power module from the storage system (see Figure 26).
2.Install the new power module into the storage system (see Figure 6 in Chapter 2).
