5. Carefully push the power supply
unit into the corresponding slot
(see also the illustration
OpenCom 510: 1-12 frame slots
on page 22). Seen from the
front, the mains inlet socket
should be on the bottom right.
Ensure that the backplane plug
of the power supply unit is se-
curely plugged into the socket
on the backplane.
6. Refit the screws to secure the
power supply in the 1-12 frame.
7. Install further interface cards if
required (see also Installing In-
terface Cards starting on
page 25).

Backplane

The BPV+1-12 backplane of the
OpenCom 510 supplies the modules
installed in the 1-12 frame with the
required power and system signals.
The backplane is also used to pro-
vide access to the PCM highway (for
transmitting utility data), the LAN
(for exchanging signalling data) and
to the system clock circuits.
The backplane has vertically ar-
ranged sockets for the backplane
plugs of the modules:

8. Switch the OpenCom 510 on. To
do so, reconnect the power sup-
ply unit with the mains supply (if
you are powering the
OpenCom 510 with two power
supply units, connect the second
unit as well).
The system will now start up and
all modules (interface cards) will
be re-initialised.
9. Observe the module LEDs during
start-up of the OpenCom 510.
Information on indicators can be
found in the chapter Modules
starting on page 52.
The MPS+1-AC power supply
■
units and the MC+1-3 central
control module are each con-
nected by means of a 96-pin
spring contact strip.
The interface modules are each
■
connected by means of a 48-pin
spring contact strip.
The backplane also carries the sys-
tem serial number (etched into the
backplane chip).
