Node Card Maximums
The following maximums are applicable to operation using SW release 5.04 or later.
l An NPC must be fitted in an INUe where specified below. The NPC provides
power supply load sharing with the NCC, allowing the overall loading to be
increased. Should the NPC fail, airflow from the 2RU FAN is increased to
compensate.
When planning the number and type of cards to be installed in an INUe or INU, the
following rules must be observed. Individual card consumptions are detailed under
Power Consumption.
CAUTION:The loading rules below must be observed by the installer -
there is no built-in mechanism to report or limit an incorrect dimen-
sioning of power supply consumption.
INUe Loading Rules for Operation up to 55ºC (131ºF)
The following loading rules must be followed when dimensioning the total power con-
sumption of an INUe that is required to operate in ambient temperatures up to 55ºC
(131ºF):
l If the total power consumption of all cards installed exceeds 85 watts, an NPC
must be fitted, and a 2RU FAN card must be fitted.
l With this configuration confirmed the maximum INUe loading enabled is 125
watts. The one exception/condition is that the combined installed total of DAC
GE3 cards must not exceed four.
CAUTION:55ºC (131ºF) operation does not apply to the PCC. Oper-
ational ambient temperatures with a PCC installed must not exceed
45
