Wiring the DC Inputs

The 7705 SAR-8 has two D-Sub 2W2 connectors mounted on the front of the chassis. These
connectors are the DC power feed points for DC source voltage from the DC circuit. A 13 ft
(4 m) wiring harness is available from Alcatel-Lucent to facilitate the DC source-to-router
connection. The harness has a 2W2 connector at one end and open-ended wires at the other
end.
For redundant power configurations, you must use two DC power feeds (one for each power
connector on the 7705 SAR-8).
7705 SAR-8 Installation Guide
The 7705 SAR-8 requires a minimum of one DC power source to operate, but using two
DC power sources is recommended for redundancy.
The 7705 SAR-8 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 strap, and bus bars must
be brought to a bright finish and then coated with an antioxidant before connecting them.
To comply with the GR-1089-CORE requirement R4-9 [31] standard for electromagnetic
compatibility and safety, all intra-building ports are specified for use with cables that are
shielded and grounded at both ends.
Ensure that all power is OFF from the DC circuit. Locate the circuit breaker on the panel
board that services the DC circuit and switch the circuit breaker to the OFF position. For
extra safety, you can tape the handle of the circuit breaker in the OFF position.
When wiring the unit, the chassis ground connection must always be made first and
disconnected last.
