Filler Plates
Figure 8 shows a filler plate. Filler plates (blank panels) are required on all empty slots to
prevent dust accumulation, help control airflow, help confine electromagnetic interference,
and for safety reasons. Filler plates do not have board components or connector pins.

Power System
The 7705 SAR-8 has two power connectors mounted on the front of the chassis. These
connectors provide access for two independent –48/–60 VDC power feeds, providing power
redundancy for the system. When only one power feed is used, the system does not have
power supply redundancy. The 7705 SAR-8 has a distributed power design, where each
CSM and adapter card provides independent power for its own functionality. The power
system has no field-replaceable parts.
