position with respect to that of the bias pins of the Power Supply Units. When the system
is delivered to the customer, the housings which are not used are covered with a panel.
The front panel of the A1532 Power Supply Unit is shown in Fig. 3.6. On the bottom left
there is a green LED (
+48
) which lights up when the +48 V power supply is present; if it
is off it indicates that there is a fault.
The front panel of each Power Supply Unit has a grid for the cooling of the unit.
Moreover, a convenient handle allows to insert or extract easily the unit from the relevant
backplane connector.
The A1532 unit has been designed to be automatically disconnected from the output bus
in case of a unit malfunctioning. This allows to the other units to keep on working
properly even if one of the units does not operate in a proper way.

WARNING: The power supply units can be inserted or extracted from the
appropriate housings only if the system is turned off and unplugged from the
mains.
