Calculating the Chassis Base Power Budget for Your EX6210 Switch

Calculating the Maximum System Power Required for Your EX6210 Switch Configuration

Step
1 Start with the chassis base power budget
of your switch.
Compute chassis base power budget as
shown in "Calculating the Chassis Base
Power Budget for Your EX6210 Switch" on
page 115.

The chassis base power budget for an EX6210 switch is the sum of the maximum power
requirements of the fan tray and two SRE modules. See
requirements of the fan tray and the SRE module.
Thus the chassis base power budget is :
= 300 W + ((2) * (100 W))
= 300 W + 200 W
= 500 W
NOTE: The chassis base power budget of the EX6210 switch remains the
same, even if only one SRE module is installed in the switch.
To calculate the maximum system power required for your EX6210 switch configuration,
determine the maximum internal power requirements of all the components installed in
the chassis, and then divide this result by the power supply efficiency.
To calculate the maximum system power requirements of an EX6210 switch, follow the
instructions in Table 52 on page
Chapter 7: Planning Power Requirements
