The optional HP 1650lA Expansion Frame has four components:
• the expansion frame consisting of the five-slot card cage, power
supply, and fans.
• an expansion frame interface board, which occupies a fIXed,
non-removable slot beneath the five-slot card cage in the HP
1650lA. It contains a port designed to receive a 68-pin "D"
connector.
• a mainframe interface board, which,
if
not already installed in
the HP 16500A mainframe, you may insert into anyone of the five
card slots marked A-E. It also contains a port designed to
receive a 68-pin "D" connector.
• a flat, bi-directional cable 2 meters long with a 68-pin "D"
connector at each end. This cable is long enough to allow the
units to be stacked vertically or placed side-by-side. The cable is
externally shielded to reduce RFI emissions.
To connect the HP 1650lA to the HP 16500A, follow these steps:
1. Insert one of the 68-pin cable connectors into the port located on
the right side of the mainframe interface board.
In order to ensure correct insertion, the 68-pin "D" connectors are
asymmetric in shape. They only fit into their respective ports when
oriented to match the shape of the ports.
2. Insert the other 68-pin connector into the port on the expansion
frame interface board.
Make sure the connector is properly seated into the port by pulling the
connector without pressing the release tabs.
If
the connector
is
properly seated it
will
remain connected to the port.
