Replacing System Fans

The fan replacement spare kit for the CG2300 server contains six 80mm fans. Each fan module is exactly like the fans in the
server, i.e., the bracket and plastic finger guard are attached. For ordering information, see the
Configuration Guide
. The latest version of the Configuration Guide is located on the Kontron support website at
http://cbu.kontron.ca. (CRMS – CG2300 - Ordering Guide). The fans are hot-swappable, so no service interruption is usually
required. However, if service interruption is required for installation considerations, fan replacement by a skilled technician
should take 15 minutes or less.
CAUTION: Because the fans are hot-swappable, you do not need to shut down the server system and disconnect the power and
external devices. Instead of removing the chassis cover, as is customary for working with internal components, simply press the
blue unlock button on the cover and slide the cover backwards on the shoulder screws to access the fan area.
Do not completely remove the top cover
power is on. If the top cover has been removed to access components internal to the system other than the hot-swappable fans,
you must power off the server and unplug the power cords.
The six 80x38mm fans, configured as three redundant pairs are located behind the front panel board. (See XX, "Q")These fans
are in front of the support cross bar and the fan control board. They provide cooling for the CPUs, memory DIMMs, PCI riser
assemblies, and HDD drives.
To replace a fan:
1. Unfasten the shipping screw, if used, on the left side of the chassis cover.
2. Slide the top cover back to the support cross bar so the fans and the CPU cables behind them are visible.
3. Determine which fan has failed by finding the LED that is amber. (The LED is next to the blue grommet on the top of
each fan assembly).
4. Remove the failing fan by grasping both sides of the fan assembly, using the plastic finger guard on the left side and
pulling the fan out of the metal enclosure that houses the fans and the power cables. (Figure 5 , "C" and "D")
