3.3.2Connecting the 50-Pin SCSI Interface Cable
Your computer’s existing 50-pin SASI/SCSI interface cable does not have to be
replaced. However, because the cable may not be quite long enough to reach the SCSI
port on the Roadrunner, a short extension cable (part number DWB-10313-00) has
been included in your installation kit. One end of this cable plugs into the 50-pin J1
connector on the Roadrunner board. The other end of the cable plugs onto the end of
your existing SCSI interface cable. Using the colored stripe on the cables as a
reference, make sure all cable connections are made pin-1 to pin-1.
If you’re upgrading a
standard
AM-3000M system and intend on using the CPU SASI
port also, you may need to obtain an additional 50-pin interface cable and bus
terminator.
3.3.3Connecting DC Power Cable to Roadrunner Board
The Roadrunner board has a standard 4-pin DC power connector. Simply take one of
the 4-pin DC power cables extending from your power supply and plug it into the
Roadrunner board. For AM-3000M and AM-3000 VME systems a DC power "Y" adapter
cable is provided as part of the hardware kit. If all available DC power cables from the
main power supply are already in use, you’ll need to attach the adapter cable to the
device closest to the Roadrunner board and share the power feed. To do this, simply
unplug the nearest existing DC power cable and attach the "Y" adapter cable to it. Plug
the single male end of the adapter cable onto the female DC power cable. Then plug
one of the two female adapter connectors into the original device and the new
Roadrunner board. If for some reason the adapter cannot be split far enough, you can of
course use the adapter cable for any two devices, and use the freed main cable for the
Roadrunner board.
Although the power connectors are keyed, with extra force they can be installed
incorrectly
, so be careful!
