Replacing a VNX BBU (Battery Backup Unit)

To replace a Battery Backup Unit (BBU) in an EMC VNX5200, VNX5400, VNX5600, or VNX5800, follow these steps. First, identify the faulty BBU, either A or B, in Unisphere. Once identified, remove the BBU from the base module by pushing the orange release tab to the right while holding the BBU’s handle. Carefully place the removed BBU on a clean, static-free surface to avoid any potential damage.

To install the replacement BBU, hold it with the white label facing up and align it with the slot in the base assembly. Push the BBU into the slot until it clicks securely into place. After the installation is complete, check the System Health page and Unisphere to confirm that the new part is functioning properly and is marked with an OK status icon.
