Passport 8300 Power Considerations 

For the Passport 8306 and 8310 Chassis, the number of 8301AC power supplies that you need to 
install—1, 2, or 3—depends on the following:

•

the number of modules installed in the chassis 

•

PoE requirements 

•

whether you want an optional redundant power supply 

 lists the number of 8301AC power supplies to install based on the number of installed 

modules and your power supply redundancy choice. 

 lists the available system power for the 

8306 and 8310 chassis. 

 lists the input power specifications for each of the modules.

If a power supply fails when you have a redundant power supply installed, the Passport 

8300 continues to operate with no interruption of service. The chassis will continue to supply 
the same module and PoE output power with the remaining power supplies. A trap and syslog 
message will indicate that the configuration is non-redundant. 

Nortel Networks recommends that you operate the Passport 8300 in a redundant configuration 
at all times to ensure maximum network up time.

Nortel Networks recommends that you install each power supply on its own 

dedicated branch circuit. When you plug the power cord for each power supply into a 
separate AC circuit, the redundant power supply also provides protection against the 
disconnection or failure of an individual branch circuit or power supply failure.
