INUe Loading Rules for Operation at 45ºC (113ºF)
The following loading rules must be followed when dimensioning the total power con-
sumption of an INUe that is operating in ambient temperatures that do not exceed
45ºC (113ºF):
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 150
watts. The exceptions/conditions to this rule are:
o
INUe loading is limited to 140 watts if the installed total of DAC GE3 cards
exceeds two.
o
The combined installed total of DAC GE3 cards must not exceed four.

INU (1RU) Loading Rules
The INU (1RU) chassis should not be loaded above the follow limits:
l 65 watts total for operation up to 45ºC
l 50 watts total for operation up to 55ºC
Elevated ambi ent temperatures should be avoi ded. The ambi-
ent temperature is the ai r temperature in the immedi ate oper-
ati ng environment of the chassis, which if installed in a rack,
is the ambient applying to its location within the rack.
CAUTION:The ambient temperature maximums must not be
exceeded. Over-temperature operation is a primary factor affecting
long term component reliability.
PCC +24 Vdc Operation
The PCC is for use with standard +24 Vdc (-ve grounded) battery-backed power sup-
ply systems.
l One PCC supports a maximum three ODUs, plus any combination of RACs
and DACs.
l The PCC +ve and -ve input terminals are isolated from chassis (ground). The -
ve input is grounded by the -ve grounded power supply connection.
l The PCC 20A fuse is fitted in the +ve input. It is a PCB mount type and is not
field replaceable.
