Notes:
1. The system software recognizes the OPT moduleas a 012 module, Even though the OPT module only
has 8 jacks, it uses 12 ports of capacity, thereby decreasing overall station capacity by four stations for
every OPT module.
2. Although these MERLIN II modules are supported, the following are the recommended modules for the
system. 400 GS/LS, 408 GS/LS, 800 GS/LS, 408 GSLS-MLX.
3 This module is not compatible with Releases 1.0 and 1.1: it applies to Release 2.0 and later.
