Fitting the ideA interface without a backplane
Before fitting the
ideA i nterface without a backplane you must remove the small
black jumper link, LK1. This link can be found next to the blade terminal labelled
+5V(RED) on the ideA i nterface board. A safe way to store the link is to place it on
one pin only.
WARNING: IF YOU DO NOT REMOVE LK1 FROM THE
ideA I NTERFACE
BOARD YOUR COMPUTER COULD BE DAMAGED.
You will find a bunch of cables attached to the side of the power supply with a
cable tie. Some of these are needed to power the
ideA i nterface and hard disc.
Use a pair of scissors to cut the cable tie, taking care not to cut or damage any of
the cables themselves.
I
dentify the hard disc power cable. It has four wires going into a four-way plastic
connector, plus single red and black wires.
Connect the red and black wires to the ideA i
nterface blade terminals. The
terminals are clearly marked OV(BLACK) and +5V(RED). FITTING THESE WIRES
THE WRONG WAY ROUND WILL DESTROY THE ideA I NTERFACE.
Find the expansion connector located towards the right hand side of the computer
j
ust over half-way back from the front of the main circuit board. (This is where a
backplane would normally be connected). The
ideA i nterface plugs into the
connector with the components towards the front of the computer. The interface
will only fit correctly into the connector one way round. For the moment leave the
40-way ribbon cable, attached to the interface, where it lies.
Using one of the cable ties supplied, secure the remaining yellow wire so that it
cannot come into contact with the power supply or the surface of any circuit board.
Fitting the ideA interface with a backplane
Before fitting the ideA i
nterface with a backplane you must check that the small
black jumper link, LK1, is in place. This link can be found next to the blade terminal
l abelled +5V(RED) on the
ideA i nterface board.
WARNING: IF LK1 IS NOT FITTED THE
ideA I NTERFACE COULD BE
DAMAGED.
The backplane must be a four-layer type. If in doubt, contact your supplier.
Plug the ideA i
nterface into a free socket on the backplane, with the components
facing upwards. The interface will only fit correctly into the connector one way
round. For the moment leave the 40-way ribbon cable, attached to the interface,
where it lies.
Fitting the hard disc
Re-read the earlier warnings about handling, then unpack your hard disc.
Locate the mounting cradle and mounting screws. If you have more than one set
