You need to remove the CMOD to service it or its internal components.
Before You Begin
For component serviceability, locations, and designations, see About System Components.
For servers equipped with SW 1.0 and with versions of Oracle ILOM older than 22.214.171.124, use cold service. See Prepare the Server for Cold Service.
For servers equipped with SW 1.1 and with Oracle ILOM 126.96.36.199 or newer, use cold service or warm service. For warm service, see Prepare the Server for Warm Service.
In an eight-CMOD configured server, CMODs belong to either a left or a right group. CMODs 0-3 are in the leftmost group, and CMOD s 4-7 are in the rightmost group. If you know the group, then you know which group of four fan modules to remove. If you are removing a CMOD in a failed state, the lit fault indicator for the CMOD on the FIM shows you the group to which the CMOD belongs. In a four-CMOD configured server, remove the leftmost group of fans.
Caution - Pinch point. Keep your fingers clear of the underside of the lever.
The lever disconnects the CMOD from the midplane and its DPCC.
