You might need to move the cable-management arm (CMA) aside to access components or complete
service tasks. If needed, you can also remove the CMA from the 2145-92F expansion enclosure.
About this task
The cable management arm (CMA) consists of an upper and lower arm assembly, as Figure 64 on page

removed from the enclosure individually.
