— Chassis, NN46200-309.
Procedure steps
Step Action
1 Add the total (3.3 V and 12 V) input power consumption
(wattage) for all components (modules and fan trays or cooling
modules).
2 Refer to the output power rating of the power supply based on
the input connection.
If either the individual or the combined power requirements for
the components exceed the power supply rating, you need to
add at least another power supply to your configuration.
For the 8005DI DC power supply specifications, see
“Model
8005DI DC power supply” (page 47) . For the 8005DC power
supply specifications, see “Model 8005DC power supply” (page
48)
3 Consider your redundant power supply needs. If one power
supply satisfies your system power consumption needs, a
second power supply provides redundancy. If two power
supplies satisfy your system power consumption needs, a third
power supply provides redundancy.

Preparing cables for installation
Prepare the cables for installation of the power supply of the Ethernet
Routing Switch 8300.
Nortel does not supply the cables for connecting the DC power supply to
the DC input power source. Select cables that comply with the electrical
code of the country where you use the DC power supply.
CAUTION
Risk of equipment damage
Make sure that the connection cable used with the DC power
supply is appropriate for use with the DC power source to which
the power supply connects. Consider gauge, flammability, and
mechanical serviceability when you determine which cables to
use.
