Several FRUs in the BA430/BA440 enclosure are system specific
(Table 3–2). Their presence depends on which CPU and mass storage
devices are installed. Several different modules, disk ISEs, and tape ISEs,
may be present. Refer to the applicable CPU maintenance manual for a
complete list of options. All such devices are also FRUs.

3.2 Installing and Removing Modules
NOTE: The illustrations in this section show the BA440 enclosure.
Duplicating the same basic illustrations for the BA430 enclosure is
unnessary. The removal procedures are the same for both enclosures.
Modules designed for BA400-series enclosures have wide handles that
provide both external I/O connections and an electrical and environmental
seal for the card cage. Standard Q22-bus modules that are also used in
other enclosures, such as the TQK70, use a blank cover instead of a handle.
There is a different removal procedure for the three types of modules.
• Modules with ratchet ejector handles
• Modules with attached handles
• Modules with covers
