Internal Power Supply

When an internal Power Supply Card, model 751313MC or 751318MC is used,
then either 120 Vac or 130 Vdc must be supplied to the shelf via one of the power
cables provided. The Power Supply Card itself operates from either AC or DC. In
this case, it is very important that the jumper W1 be installed properly. Please
refer to section 3.3 on page 26 an d section 3.3.1 on page 29 for an explanation of
the jumper.

When an internal Power Supply Card, model 751316 or 751319MC is used, the
DC power cable supplied must be used to supply the 48V to TB3 (the power
supply does not use -48 Vdc from TB2).
