NCC
Node Control Card
The NCC is a mandatory plug-in for each INU/INUe. It performs key node
management and control functions, and provides various dc rails from the
-48 Vdc input. It also incorporates a plug-in flash card, which holds node
configuration and license data.
FAN

One FAN must be fitted in an INU or two in an INUe to provide cooling,
except that from March/April 2007 a single 2RU FAN will replace 1RU FANs
in an INUe. Each FAN is fitted with two long-life axial fans plus monitoring
and control circuits.
