Note:
In a newly installed chassis that requires two power supplies (nonredundant
configuration), you must turn on both units within 2 seconds of each other. If you wait
longer to turn on the second power supply, both power supplies will turn off. To correct this
condition, turn off both power supplies, wait at least 30 seconds, and turn both power
supplies on again within 2 seconds.
Operational Notes for the Power Supply
A Passport 8010 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 five installed modules requires a minimum of two power
supplies for a nonredundant configuration. A redundant configuration for such a chassis requires three
power supplies.
In a chassis with a nonredundant power supply configuration, if one power supply fails, the system
loses power and network connectivity.
In a chassis with two installed power supplies, you can add a third power supply without powering
down the chassis.
When you first install a Passport 8000 Series chassis that requires two power supplies (nonredundant
configuration), you must turn on both power supply units within 2 seconds of each other. If you wait
longer to turn on the second power supply, both power supplies will turn off. To correct this condition,
turn off both power supplies, wait at least 30 seconds, and turn both power supplies on again within
2 seconds.
