NOTE: The QFX10000-12C-DWDM line card is designed to comply with
NEBS regulations on the QFX10000 line of modular switch chassis when
these switches are used in typical configurations. In a typical configuration,
a QFX10008 switch supports up to eight line cards, with up to four
QFX10000-12C-DWDM in any of the eight slots.
To comply with EMC regulations, you must also install front panel on the
QFX10008 chassis. See
For example, for a QFX10008 with five QFX10000-36Q line cards and three
QFX10000-30C, the maximum power consumption is:
= 5 (power consumed by QFX10000-36Q in watts) + 3 (power consumed by
QFX10000-30C line cards in watts)
= 5 (675 W) + 3 (1150 W)
= (3375 W + 3450 W)
= 6825 W
Add the power consumption from step
3.
step 2.
To continue from the previous example, add the wattage from five QFX10000-36Q
and three QFX10000-30C cards to a redundant configuration.
(6825 W) + (2560 W)
= 9385 W required
