Front Features
The SC939HN-R2K04B 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 managment device and the other to another server.
•
Redundancy: For redundant IPMI managment, connect each port to a different subnetwork,
that is, each to a different switch.
