General Checks

2.1 Checking the Configuration
When checking the configuration, proceed as follows:
• Compare printouts by the AIMS Project Manager (block diagram, layout) with
the project planning data (expansion card configuration, terminals).
• Check whether any customer requests for modifications have been taken into
account (for the system configuration, see "Part 5: Configuration").
• If changes were made to the DECT system, check the locations of the radio
units. Carry out follow-up measurements where necessary.
• If changes were made to the terminals (e.g. other terminal types), check per-
formances, line lengths, S-bus configuration.
2.2 Visual Inspection with the System out of Operation
Carry out the following visual inspections before connecting the PBX to the power
supply:
• Is the installation correct? (wire colours, S bus terminating resistors, loop resis-
tors, see "Checking the Installation", Page 4.123).
• Is the protective earth and equipotential bonding in place (no earth loops)? (see
"Checking the Installation", Page 4.123).
• Are the expansion cards correctly fitted?
• Are the jumpers correctly fitted (e.g. on the 2025 / 2045 mainboard, ISDN-
04ST ISDN card, OI-2DOOR special card)?
• Is the uninterruptible power supply fitted?
• Are the dummy covers fitted?
• Is the PBX set up for the required supply voltage?
(e.g. the 48VDC power supply needs module DC-48V).
• Have the correct connecting cables being used for the various applications?
(See "Special Interfaces", Page 4.73.)
