Chapter 9. DiagnosticsGFK-2950C February 2018 3999.4.3 Loss of or Missing Option Module (Group 4)The fault group Loss of or Missing Option Module occurs when a LAN interface module, BTM, or BRMfails to respond. The failure may occur at power-up or store of configuration if the module is missingor during operation if the module fails to respond. This may also occur due to hot removal of anoption module.Default action: Diagnostic. Configurable3C hex/60 decimal, Module in Firmware Update ModeThe CPU generates this error when it finds a module in Firmware Update mode. Modules in thismode will not communicate with the CPU.Correction1) Run the firmware update utility for the module.2) Reset the module with the push-button.3) Power-cycle the entire system.4) Power-cycle the rack containing the module.63 hex/99 decimal, Module Hot RemovedThe CPU logs this fault when it detects hot removal of an option module such as the LAN interfacemodule. No correction necessaryAll Others, Module Failure During ConfigurationThe CPU generates this error when a module fails during power-up or configuration store.Correction1) Power off the system. Replace the module located in that rack and slot.2) If the board is located in an expansion rack, verify BTM/BRM cable connections are tight and themodules are seated properly; verify the addressing of the expansion rack.3) Replace the BTM.4) Replace the BRM.5) Replace the rack.9.4.4 Addition of, or Extra Rack (Group 5)This fault group occurs when a configured expansion rack with which the CPU could notcommunicate comes online or is powered on, or an unconfigured rack is found.Action: Non-configurable.1, Extra RackCorrection1) Check rack jumper behind power supply for correct setting.2) Update the configuration file to include the expansion rack.Note: No correction necessary if rack was just powered on.
