Installing the Router 3-7
Making Network Connections
Warning Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable,
detach the end away from the router first to avoid possible electric shock. Network hazardous
voltages are also accessible on the BRI module in the area of the BRI port (RJ-45 connector), even
when power is turned OFF. (See Figure 3-7 and Figure 3-8.)
Figure 3-7 Four-Port BRI Network Processor Module
Figure 3-8 Eight-Port BRI Network Processor Module
Note The multiport BRI network processor module requires that all its interfaces connect to the
same carrier or from carriers with synchronized master clocks. If the BRI module connects to ISDN
interfaces that have an unsynchronized master clock, the module’s interfaces will occasionally lose
some packets.
