4.4.1 Slots

The OpenCom 510 1-12 frame can house up to:
■
2 power supply units
■
1 control module
■
12 interface cards (trunk or subscriber modules) split into 2 separate groups.
The following slots are provided for installing these modules:
Legend
A Slot for group 1 power supply unit
B Slot for group 2 power supply unit
0 Slot for central control module
C Slots for group 1 interface cards (slots 1 - 6)
D Slots for group 2 interface cards (slots 7 - 12)
Each of the two groups (1 or 2, or C and D, respectively, in the illustration) requires
its own power supply unit. Power for the control module is always supplied by the
group 1 power supply unit. The group 1 power supply unit must therefore always
be installed.
Modules can be installed either when the entire system is configured or as an
upgrade at a later time.
