Appendix B: Fan Replacement
The ZoneDirector 5000 includes six redundant, hot-swappable system fans (four 80mm
fans and two 60mm fans). There are also two fans located inside the power supply units.
Redundancy for the two PSU fans is only achieved when both PSUs are installed.
If any of the system fans requires replacement, the replacement procedure is identical.
Warning: Electrostatic discharge (ESD) can damage internal components such as
L
printed circuit boards and other parts. Ruckus Wireless recommends that you only
perform this procedure with adequate ESD protection. At a minimum, wear an
antistatic wrist strap attached to the ESD ground strap attachment on the front
panel of the chassis.
Open the front chassis cover of the ZoneDirector 5000. It may be necessary to
1.
extend the ZoneDirector into a maintenance position.
Identify the faulty fan. Each fan has a “service required” LED that lights Amber
2.
when the fan is malfunctioning.
Remove the faulty fan by grasping both sides of the fan assembly, using the plastic
3.
finger guard on the left side and pulling the fan out of the metal fan enclosure.
Slide the replacement fan into the same metal fan enclosure. Use the edges of
4.
the metal enclosure to align the fan properly and ensure the power connector is
seated properly in the header on the side of the enclosure.
Apply firm pressure to fully seat the fan.
5.
Verify that the (service required) LED on the top of the fan is not lit.
6.
Close the front chassis cover and return the ZoneDirector 5000 to its normal
7.
position in the rack, if necessary.
