Kontron CG2200 Carrier Grade Server Installation and Maintenance Guide
6. Unplug the three fan connectors on the fan control board by pinching the sides of the connectors
and pulling them up and off the headers on the fan control board. For assistance, see Figure 52 in
“Replacing the Fan Control Board”.
7. Unfasten the two screws that fasten the fan cage to the chassis floor. Pull the cage up out of the
chassis and set it and the screws aside.
8. Return now to the replacement procedure where this step was called out.
5.3 Replacing Fans
The fan replacement spare kit for the CG2200 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 CG2200 Carrier Grade Server Configuration Guide. The latest version of the Configuration Guide
is located on the Kontron support website at
http://us.kontron.com/support/ (search for
CG2200, click on Product Downloads, then 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, you can 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 while the system is running because there is a 12V energy
hazard in the server when 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 remove the
power cords.
The six 80x38mm fans, configured as three redundant pairs are located behind the front panel board.
(See Figure 2, “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. (Figure 47, “A”)
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.
