The numbers in parentheses on the MCU status page is the maximum that the MCU has reached since it's last restart/reset.

Format of displayed values
In many cases, the values displayed on this page are shown in the format A (B) / C; this represents:
- A – the current value of this statistic
- B – the maximum achieved value of this statistic (since last reset)
- C – the maximum allowable number for this statistic (this varies by MCU model)
The maximum value (C above) for the "ports in use" fields depends on the number of port licenses allocated to the unit. One port license is required for standard definition (SD) ports, two for each high definition (HD) port.
Statistics for which there is no set maximum are displayed as A (B), where A and B have the meanings described above.
Where the highest value attained is shown in parentheses (i.e. B in the above example), this value can be reset by selecting Reset maximum values. These values can be useful in monitoring peak MCU usage over a period of time.
