Passport 8010 Chassis  
Instructions for replacing an installed power supply in the Passport 8010 Chassis  
Specifications for the power supply  
For more information about the Passportchassis, refer to Installing the Passport 8010 Chassis  
(part number 204518-B).  
Operational Notes  
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 latch 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.
