Figure 6-7 Data Center Server Cooling Zones
Office Friendly Server
There are six interchangeable, hot-swappable dual-rotor server fans in the Office Friendly rx2660
server. The Office Friendly fans have two fan rotors per fan. Fans 1 through 4 are located in a
removable fan carrier directly behind the front bezel. Fan units 5 and 6 are located in a removable
I/O fan carrier between the SAS backplane and the I/O card cage. The server is set up into three
cooling zones. Fans 1 and 2 cool Zone 1. Fan 3 and 4 cool Zone 2. Fans 5 and 6 cool Zone 3. Fan
redundancy is only supported in Zone 1 and Zone 3. If you lose one fan rotor in either of these
zones, the rest of the fans in that zone run at maximum speed and the server does not shut down.
If you lose one fan rotor in Zone 2, the BMC performs a soft shutdown in 40 seconds.
Figure 6-8 (page 150) shows the fan and cooling zone locations.
