After normal startup of OM200, the indicator displaying letter C flash indicates that OM200 has
detected IP address conflicts.
OM200 single-chassis system can provide up to 48-line with different analog line type configuration
combinations, and OM200 dual-chassis system (main chassis and expansion chassis) can provide
maximum of 96-line with different analog line type configuration combination. OM200 dual-chassis
system is a logical integrated system formed by adding an expansion chassis and interface cards on
top of the single chassis system. An expansion cable is required to connect the two chassises, and the
operation of the main chassis will not be affected when connecting the expansion cable, suitable for
on-site capacity expansion. The system resources (e.g. number of concurrent calls) are determined by
the main chassis, so users who are planning to expand capacity should take into account the needs for
future system resources when initially ordering the single-chassis system, to support the smooth
capacity expansion and upgrade.

Numbering definition of system interface slots: On the left side of main chassis is #1 slot (marked
with ① in Figure 1-9), on the right side of main chassis is #2 slot (marked with ③ in the Figure
1-9), on the left side of expansion chassis is #3 slot (marked with ② in the Figure 1-9), and on the
right side of expansion chassis is #4 slot, marked with ④ in Figure 1-9).
