Installing the Cooling Shroud
To install the cooling shroud:
1. Position the cooling shroud by aligning the guide slots with the guide screws on
the system-board (
Figure 12 on page 41).
2.
Push the cooling shroud down until all edges are seated in the slots, securing the
shroud to the system-board.
3. Close the appliance. See Closing the Appliance on page 30.
Memory
Your appliance supports single and dual-rank DDR3 unbuffered ECC DIMMs
(UDIMMs). DIMMs can be 1066 or 1333 MHz.
The appliance contains four memory sockets. Each two-socket set is organized into
two channels. The first socket of each channel is marked with white release levers.
General Memory Module Installation Guidelines
To ensure optimal performance of your appliance, observe the following general
guidelines when configuring your appliance’s memory.
c
Memory configurations that fail to observe these guidelines can prevent your
appliance from starting and producing any video output.
◆ Except for memory channels that are unused, all populated memory channels
must have identical configurations.
◆
Memory modules of different sizes can be mixed in sockets 1 to 4 (for example,
2 GB and 4 GB), but all populated channels must have identical configurations.
Memory modules are installed in the numeric order of the sockets beginning with 1
to 4. Your appliance supports both single channel and dual channel modes. A
minimal single-channel configuration of one 1 GB memory module per processor is
also supported in this mode.
Table 5 on page 43 shows sample memory configurations that follow the
appropriate memory guidelines stated in this section. The samples show identical
memory-module configurations and their the physical and available memory totals.
The table does not show mixed or quad-rank memory-module configurations, nor
does it address the memory speed considerations of any configuration.
