(D) Removing the Support Cross Bar

The support cross bar secures several components, some optional, in the chassis. It is the divider between the front and back.
The top cover can be pushed back to the cross bar without powering down the system in order to service hot-swappable
components in the front of the chassis. In contrast, some components in the front of the chassis, such as the front panel board or
the power distribution board, cannot be replaced without first removing the cross bar (along with all the components attached to
it). This procedure is necessary in order to have enough space to access these front chassis components.
Before you can remove the support cross bar, you first must power down the server and remove all peripheral devices and power
cord(s) and then remove the chassis cover. For instructions, see (A) in Chapter 4.
You also need to loosen the blue captive retention screws all along the cross bar and remove any components that are secured by
the captive retention screws: the riser card assemblies, the processor air duct, and the optional hardware RAID battery backup
assembly. For instructions see (B), (C), and (F) in Chapter 4.
