The Sun Storage F5100 Flash Array has 80 Flash Modules (FMods). Refer to the service label for the system designation of the modules.
When an FMod fails and needs to be replaced, the amber Fault LED on the front panel and an amber fault indicator on the spine of the FMod illuminate. In addition, the Common Array Manager software will identify which FMod has faulted.
You must remove all FMods in order to replace a motherboard.
