2.1.4 Stacking configuration
To manage more directions the “Stacking configuration” can be realized by installing up to 3 MSS, inter-
connected through the Ethernet ports in the Core-E module. In the example of Figure 10 are shown the
interconnected MSS.
Figure 10. Stacking configuration with 3 MSS
For the Stacking configuration it is recommended to enable the Static Lag Criteria.
Also with the Core protection max. 3 MSS can be interconnected as shown in Figure 11. For the syn-
chronization connection refer to par. 2.8.25.
To implement this configuration the LOS alarm on the Ethernet ports must be enabled as switching cri-
terion of the Core protection. To enable this functionality the “Ethernet LOS Criteria” feature has to be
enabled (refer to Menu System Setting in par.
3.4.4).
