Chapter 7 Setting media bay module DIP switches
N0008587  01
FEM switch settings
The DIP switches on the underside of the FEM module are used to turn the six ports on the front of 
the module on or off. You need to turn a port on for each Norstar expansion module you want to 
connect to the BCM1000. Each port also occupies one full DS30 bus. Therefore, if you have a 
fully-configured, six-module Norstar system to convert, you need to turn on all six ports on the 
FEM, and, therefore, no other module can be installed in the BCM1000.
To turn on a fiber port, set the DIP switch for the corresponding DS30 bus, as shown in 
For example, if you want to use fiber port 2, turn on DIP switch 2 (DS30 03). After the module is 
installed, an LED lights beside each active fiber port.
 shows the switch for each fiber port.
Note: 
The FEM module only supports connections to the Norstar trunk and station 
expansion modules.

 If your system is configured with a 3/5 DS30 split, DS30 07 is not 
available.
Note: 
If you turn on all six switches, you are using all the DS30 bus blocks. In this case, 
the BCM1000 can support only the FEM module. All other media bays must be empty.
Warning: 
Do not attempt to turn on ports requiring a DS30 bus that is already in service 
to another media bay module located on the same BCM1000. Doing this results in 
unpredictable behavior with both modules.
