N108 and BH101 are connected via a pair of multimode fibers, ports MM108-49 and MM108-50.

One provides connectivity for the 10.0/16 network, and the other connects the N108 ENS switch (169.230.26.0/24) to BH101.

N108:

N108 is somewhat of a mess due to lack of a real switch.
Currently the only 169.230.26.0/24 switch is in server rack 2, and is connected to the N108 ENS Switch.
The 10.0/16 fiber connects to a switch1 in node rack 3. node rack 3 siwtch 2 is connected to switch 1.
server rack 2 internal switch connects to node rack 3 switch 1.
node rack 4 switch 1 connects to node rack 3 switch 1.

BH101:

BH101 is in better order. The 10.0/16 and 169.230.26.0/24 fibers both connect to server rack 1.
node rack 3 and node rack 4 switches 1 and 2 are connected to server rack 1 switch-1-1.
switch-1-1 is vlanned to provide access to both 10.0/16 and 169.230.26.0/24 to machines in its rack.
