Wiring and Connecting the DC Inputs
The 7705 SAR-A has a dual-feed, wire-to-board, pluggable terminal block attached to the
front of the chassis. The terminals are the DC power feed points for source voltage from the
DC circuit.
For redundant power configurations, you must use both DC power feeds (one for each pair of
power terminals).
To connect the power cables to the terminal block, remove 0.35 in. (9 mm) of outer shielding
from each power cable at the router end, as shown in
Figure 17 . Table 17 identifies the key
items in the figure.

Note:
• Ensure that you read and observe all the dangers and warnings described in the Site
Preparation chapter before wiring and connecting power to the 7705 SAR-A.
• The 7705 SAR-A requires a minimum of one DC power source to operate, but using two
DC power sources is recommended for redundancy.
• The 7705 SAR-A is suitable for both DC-I and DC-C power configurations.
• All bare conductors must be coated with an appropriate antioxidant compound before
crimp connections are made. All unplated connectors, braided straps, and bus bars
must be brought to a bright finish and then coated with an antioxidant before connecting
them.
