About This Guide This guide provides the following information: • Safety and environmental guidelines for the power supply (this page) • Instructions for preparing cables to connect to the power supply (page 2) • Operational notes about the power supply (page 3) • Instructions for installing a Passport 8002PS DC Power Supply in an unoccupied bay of a Passport 8000 Series Chassis (page 3) • Instructions for replacing an installed power supply in a Passport 8000 Series Chassis (page 6) • Specificat
Preparing Cables Required tools: Crimping tool for crimping lugs onto cables; heat gun Nortel Networks does not supply the cables for connecting the Passport 8002PS DC Power Supply to the DC input power source. You can therefore select cables that comply with the electrical code of the country where you intend to use the DC power supply.
Operational Notes A Passport 8000 Series Chassis with up to five installed modules can operate with one installed power supply. For a redundant power configuration, install two power supplies. A Passport 8010 Chassis with more than six installed modules requires a minimum of two power supplies for a nonredundant configuration. A redundant configuration for such a chassis requires three power supplies.
9412FA 3. Push the power supply partway into the bay. Leave the terminal block at the side of the power supply exposed. Note: If you are installing a power supply in a new chassis, be sure to remove the bag of moisture-absorbing material from the middle power supply bay. Warning: Make sure the DC power source is off or disconnected on the remote end before you connect the terminal leads to the power supply. You may need to switch a circuit breaker or turn off the DC input power source.
428FA 6. Attach the grounding cable to the system or rack ground for your DC input power source. 7. Firmly slide the power supply all the way into the bay and tighten the retaining screws. 8. Attach the positive and negative terminal leads to the DC input power source according to the proper safety and technical specifications for your 48-volt power distribution system. 9. Turn the DC input power source on, or reset the power source circuit breaker, to provide power to the power supply.
Removing a Power Supply Required tools: Phillips screwdriver, 7/16-inch wrench In a chassis with a redundant power supply configuration, you can replace or install a power supply without powering down the chassis. 9430FA 1. Turn off the power switch on the power supply you are replacing. 2. Disable the incoming power from the DC input power source. You may need to switch a circuit breaker or turn off the DC input power source.

Slide the power supply partway out of the chassis. +DC +DC -DC -D -DCC 9427EB 7. Disconnect the positive and negative voltage leads from the power supply terminals. 9415FB 8. Disconnect the grounding cable from the ground lug on the power supply.
+DC -DC 9432FA 9. Slide the power supply all the way out of the chassis, and set it aside. 10. Install a replacement power supply following the instructions earlier in this guide. If you are not installing another power supply in this bay, install a filler panel over the opening.
