• Dual-port GbE I/O module
• Quad-port GbE I/O module
2.11 Remote Management Module 3
RMM3 is implemented on the iBMC on the server board. To use this feature, a
separately-orderable GCM4 NIC module must be installed.
2.12 Power Supply Subsystem
The power supply subsystem consists of up to two AC or DC power supply modules (two
needed for redundancy) and a power distribution board (PDB). One power supply module
is included with the server with a filler panel in the second power supply slot.
The power supply module is rated for 600W output capability in full AC or DC input
voltage range.
2.13 System Cooling
There are three main cooling areas in the NSN2U server as illustrated in Figure 9.
•
CPU2 and memory (blue in Figure 9) with four redundant , hot-swappable 80mm fans
These fans facilitate the air flow through the front bezel, over the server board,
CPU2, and out through the rear of the chassis.
• CPU1 and memory (green in Figure 9) with four redundant, hot-swappable 80mm fans
These fans facilitate the air flow through the front bezel, over the server board,
CPU1, and out through the rear of the chassis.
• PCI riser assembly (red in Figure 9) with two redundant, hot-swappable 60mm fans
These fans facilitate air flow through the fans, over the server board, any PCI add-
in cards in the riser assembly, and out through the rear of the chassis.
There is also another cooling area with two fans in redundant power supply
configurations for the power supply subsystem. These fan(s) also cool the hard disk
drives. The air flow is adequate even with a single power supply module installed as
long as the filler panel is installed in the unused power supply slot.
