Nortel Networks 8010co manual Connecting DC input power feeds to the BIP

52Chapter 2 Installation

Connecting DC input power feeds to the BIP

Danger: Due to high-energy hazards, only qualified service personnel are permitted to connect the BIP to the DC power source.

Warning: Ensure that the DC power source is off or disconnected on the remote end before you perform any of the steps in this section. You may need to switch a circuit breaker off or turn off power at the DC input source.

Nortel does not supply the cables for connecting the breaker interface panel to the DC input power source. You must select cables that comply with the electrical code of the country where you intend to use the DC-DC power supply.

Caution: As the installer, you have the sole responsibility for ensuring that the connection cable used with the breaker interface panel is appropriate for use with the DC power source to which the power supply is connected. Consider gauge, flammability, and mechanical serviceability when determining which cables to use.

You can connect up to two “A” feeds and two “B” feeds to your 8010co chassis configuration for redundancy. Each chassis can require up to 60 A service for maximum operating power.

As shown in Figure 35 on page 53, the primary B feed (B1) provides redundancy for the primary A feed (A1), and the secondary B feed (B2) provides redundancy for the secondary A feed (A2).

Note: An optional third power supply in the chassis provides redundancy and high-availability operation. In the same way, the BIP provides redundancy and high-availability operation by allowing two additional “B” feeds to provide redundancy for single or dual chassis installations.
