1.4 2U Twin2: System Notes
As a 2U Twin

configuration, the A+ Server AS -2014TP-HTR is a unique server system. With
four system boards incorporated into a single chassis acting as four separate nodes, there
are several points you should keep in mind.
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. Take care to slowly slide a 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.
Hard Drive Backplane/Drives
As a system, the A+ Server AS -2014TP-HTR supports the use of 12 SATA hard drives. A
single backplane works to apply system-based control for power and fan speed functions,
yet at the same time logically connects a set of three hard drives to each of the four nodes.
See the Hard Drives section in Section 3.4 for the logical hard drive and node configuration.
