3.7.2 Accuracy
The sensor commands must meet the following accuracy requirements. The accuracies must be
met over the specified ambient temperature and the full range of rated input voltage.

3.8 Power Management Policy
When working with Intel
®
Server Board S2600WP, the BMC on each node will monitor its fans
and temperature for critical failures. When there is a fan failure and a critical temperature event
at the same time the node will be powered down. When this occurs, the node will need to be
manually powered back on.
Additionally on Intel
®
Server Board S2600WP, the BMC on node 3 and node 4 will monitor for a
power supply over current condition or power supply over temperature condition. If either of
these occurs and the Shutdown Policy has been enabled, then the node will be powered down.
When this occurs, the node will need to be manually powered back on; but if the over current or
over temperature event is detected again, the node will be powered back off.
The Shutdown Policy setting is only shown on Node 3 and Node 4, and is disabled by default,
but can be enabled or disabled in the BIOS setup Server Management page or by using the Set
Shutdown Policy command.
