Hot-Plug Components - IBM p5 590 System Handbook

6.5.4 Hot-plug components

The p5-590 and p5-595 have hot-plug Field Replaceable Units (FRUs). This
allows most p5-590 and p5-595 components to be replaced concurrently without
the need to power off the system. Parts such as MCMs, L3 cache, memory, and
so on, still require a scheduled maintenance window to perform the replacement.
Table 6-1 provides an overview of what components are hot-plug.
