Special System Notes
With four serverboards acting as four separate nodes all incorporated into a single chassis, the
HPE Apollo kl20 server is a unique server system. The following sub-sections describe some
special notes affecting these aspects of the configuration:
•
Independent nodes
•
System power
•
SATA backplanes/drives
Independent Nodes
Each of the four serverboards act as a separate node in the system. As independent nodes, each
may be powered off and on without affecting the others. In addition, each node is a hot-swappable
unit that may be removed from the rear of the chassis. The nodes are connected to the server
backplane by means of an adapter card.
Note:
A guide pin is located between the upper and lower nodes on the inner chassis wall. This
guide pin also acts as a stop when a node is fully installed. If too much force is used when inserting
a node, this pin may break off. When inserting a node, slowly slide the node in until you hear the
click of the locking tab seating itself.
System Power
Dual 2000-Watt power supplies are used to provide the power for all four serverboards. Each
serverboard, however, can be shut down independently of the other with the power button on its
own control panel.
