Description
Both Netra[TM] V240 and the Sun Fire[TM] V240 both use the same system board assembly.

You must reconfigure the fan assembly's for the Netra version. This document
will explain the differences.

Steps to Follow
Netra V240 requires different fan assembly's to provide cooling. This system has 2 fan assembly's, one for the front and rear of the unit. Due to this difference you must follow the caution shown below.

Caution - The system board ships with CPU heat sinks containing fans. Before installing the replacement system board into the Netra 240 server chassis, you must first remove the fans from the CPU heat sink assemblies.
375-3120    Motherboard w/ 2 ? US IIIi 1.28GHz
375-3178    Motherboard w/ 1 ? US IIIi 1.28GHz
The CPU heat sink fans must be removed to enable connection for the
rear/front fan assembly. The rear fan assembly uses connectors P0F0
for the front fan, and P0F1 for the rear fan in this assembly. Also
for the front fan assembly you use connectors F3 for the left hand
fan and F2 for the right hand fan in this assembly.
Note: If you fail to remove the heat-sink fans from the processors
you will see sensor failures from the I2C buss. Always replace the
heat sinks after removal of the fan's.
Note: Be sure to re-attach fans to heat sinks of the system board
being returned.
