Front Features
The SC939HC-R2K04BP is a 3U chassis holding 12 discreet computing nodes. The chassis
front offers access to the dual power modules. It also includes two dedicated LAN ports to
provide IPMI management capabilities for all nodes.
Note
: The IPMI connections can be used in two ways.
•
Cascade: Connect one to a management device and the other to another server.
•
Redundancy: For redundant IPMI management, connect each port to a different subnetwork
(each to a different switch).
