Installing an out-of-band protection splitter
If a 1+1 protected configuration requires an out-of-band protection splitter, connect the
CMU Management ports to the management network as shown in Figure 105.
Use straight-through Cat5e cables with a maximum length of 2 m to connect the CMUs to
the splitter.
At the edge of the network (the ‘last hop’), if no management network equipment is
available, the two LAN ports can be connected using a protection cable. The cable pin
outs are specified in Protection cable on page 4-17.
