VME bus backplane (Application Module)
The six-slot VME bus backplane provides connections (at J1 and J2) for
circuit cards installed in the front of the Application Module. The upper
connector, J1, provides access to the VME bus for data signals. The J2
connector at the rear of the backplane provides connections for the
transition cards. These are not the J1 and J2 connectors on the I/O subpanel.
Power sense card (Application Module)
The power sense card monitors over-voltage and under-voltage conditions
for each output of the power supply. The power sense card is cabled to a
power monitor on the I/O subpanel or, in newer systems, to a central bracket
in the bottom of the AEM. Signals from the power monitor are extended to
the system monitor in the pedestal of the column. The system monitor
checks the status of all power- and cooling-related components in the
column.
Alarm cables must be extended from a stand-alone AEM column to the
Meridian 1 as described in ÒAlarm connectionsÓ in the
Application
Equipment Module Installation Guide
(NTP 553-3201-200).
I/O connectors (Application Module)
The I/O connectors are 9-pin and 25-pin subminiature D-type connectors.
External cables connect to the I/O panel on the AEM. All connectors are
shielded from RF and are integral parts of the external cables.
