Operational Notes

A Passport 8010 Chassis with up to fi ve installed modules can operate with one i nstalled power su pply. 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 nonr edu ndan t configuration. A red unda nt configuration for su ch a ch assis requires thr ee 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, bot h power suppl ies will latch of f. To correct t his condi tion, turn off both power supplies, wait at least 30 seconds, and turn both power supplies on again within 2 seconds.
