Table 54: Calculating System Thermal Output 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.
2 Total Base Power Requirement of the
Installed Line Cards = (Number of line cards
installed in the switch) * (Maximum Power
Requirement of line card)
For maximum power requirements of
different EX6210 switch components, see
Table 51 on page
3 Total Power Requirement of the Installed
Line Cards = (Total Base Power
Requirement of the Installed Line Cards) +
(Total PoE+ Power Requirement of the
Installed Line Cards)
NOTE: Thermal output from the PoE+ line
cards is dissipated at the PoE powered
device end, so this Power Requirement is
not included in the system thermal output.
4 Maximum Internal Power Requirement of
the Switch = (Chassis Base Power Budget)
+ (Total Power Requirement of the Installed
Line Cards)
