3.2.6 Powering
The Host Unit is powered by -48V DC through a DC power terminal block on the rear. An ON/OFF switch is
provided at the PSU front panel. The switch applies power to the Host Unit internal power supply, which
distributes the operating voltages to lines cards installed in the Host Unit shelf.
3.2.7 Host Unit Interface
The Host Unit interface consists of the various connectors, switches, terminals and LED indicators that are
provided on the front and rear panel. The Host Unit user interfaces are described in Table 1and indicated in
Figure 9.
