Chapter 1: Introduction
1-6 2U Twin: System Notes
As a 2U Twin conguration, the SuperServer 2028TP-DC1R/DC1TR/DC1FR is a
unique server system. With two system boards incorporated into a single chassis
acting as two separate nodes, there are several points you should keep in mind.
Nodes
Each of the two serverboards act as a separate node in the system. As independent
nodes, each may be powered off and on without affecting the other. 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 1280 Watt power supplies are used to provide the power for both serverboards.
Each serverboard however, can be shut down independently of the other with the
power button on its respective control panel.
Hard Drive Backplane/Drives
As a system, the SuperServer 2028TP-DC1R/DC1TR/DC1FR supports the use of
24 hard drives (SAS and SATA). 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 twelve hard drives to each serverboard. Consequently, RAID setup is limited
to a twelve-drive scheme (RAID cannot be spread across all 24 drives). See the
Drive Bay Installation/Removal section in Chapter 6 for the logical hard drive and
node conguration.

with a serverboard, processors, system memory etc., please turn to the chapter or
section noted in each step for details on installing specic components.
2-2 Unpacking the System
You should inspect the box the 2028TP-DC1R/DC1TR/DC1FR server was shipped
in and note if it was damaged in any way. If the server itself shows damage you
should le a damage claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the
2028TP-DC1R/DC1TR/DC1FR server. It should be situated in a clean, dust-
free area that is well ventilated. Avoid areas where heat, electrical noise and
electromagnetic elds are generated. You will also need it placed near a grounded
power outlet. Read the Rack and Server Precautions in the next section.
2-3 Preparing for Setup
The box the SuperServer 2028TP-DC1R/DC1TR/DC1FR was shipped in should
include two sets of rail assemblies, two rail mounting brackets and the mounting
screws you will need to install the system into the rack. Follow the steps in the
order given to complete the installation process in a minimum amount of time.
Please read this section in its entirety before you begin the installation procedure
outlined in the sections that follow.
