2.14 I/O Module
Space on the chassis floor with support standoffs is provided for adding an optional I/O module at the rear
of the server. An I/O module connector (and use of a smaller connector also used for RMM4 support) is
how the I/O module is connected to communicate with the server board.
2.15 Power Supply Subsystem
The power supply subsystem consists of up to two AC or DC hot-swappable power supply modules (two
needed for redundancy) and a power distribution board (PDB). The server comes with one power supply
module and a filler panel in the second power supply slot. The second redundant power supply is
separately-orderable.
The power supply module is rated for 650W output capability in full AC or DC input voltage range. The
minimum steady-state DC input voltage at which the equipment remains fully operational is -38 VDC. The
nominal operating voltage of the DC system is -48 VDC.
The server also includes an auxiliary power dongle from the power distribution board for use with
optional, additional cards.
2.16 System Cooling
There are two cooling areas in the CG1200 server as illustrated in
Figure 8. All system components except the PCI riser card assembly and components under it are
cooled by a set of four CPU/DIMM dual rotor fans mounted near the front of the chassis behind the SAS
HDD bay. The PCI riser card assembly is cooled by a separate fan located in front of the riser assembly
on the left side of the chassis
Internal power supply fans cool the power distribution board (PDB) and power supply modules.
