Input/output cables
The Application Module has two types of I/O cable. These include
¥ internal cables that connect circuit cards to disk and tape drives within
the Application Module
¥ external cables that connect the Application Module to the
Meridian 1, the system console, and application terminals (if
applicable)
Internal I/O cables
Internal cables interconnect components that are not connected through the
VME bus backplane. Table 77 lists the Application Module internal cables.
Figure 58 shows the internal cabling scheme.
