Physical and Functional Description of Router
Figure 1-8 DC-Input Power Shelf—2000 Watts
Caution A router configured for source DC operation must be operated with 4 DC-input
PEMs installed at all times for electromagnetic compatibility (EMC).
Note DC PEMs support online insertion and removal (OIR) which means that you can
remove and replace one PEM in each load zone (A1 or B1; A2 or B2) while the
system remains powered on.
DC power to the router is provided from cables from a DC power source that are
connected to threaded terminal studs on the back of the DC-input power shelf as
shown in Figure 1-9.
