Removing a Fan Module from a TCX1000-RDM20
The fan modules in a TCX1000-RDM20 are hot-removable and hot-insertable field-replaceable units (FRUs)—you can remove and replace them without powering off the TCX1000-RDM20 or disrupting TCX1000-RDM20 functions.
The fan module must be replaced within 96 hours of fan failure.
Replace the fan module within two minutes of removal to prevent chassis overheating. Before removing the fan module, ensure that you have a replacement fan module available.
Before you remove a fan module from a TCX1000-RDM20, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
Ensure that you have the following parts and tools available:
ESD grounding strap
Antistatic bag or an antistatic mat
To remove a fan module from a TCX1000-RDM20 (see Figure 1):
- Place the antistatic bag or the antistatic mat on a flat, stable surface.
- Attach an ESD grounding strap to your bare wrist to prevent damage to the equipment caused by static discharge. Connect the strap to one of the ESD points on the chassis.
- Begin by loosening the captive thumb screws on the installed fan unit.
- Grasp the large captive screws on the fan module to slide
the fan module halfway out of the chassis.
To avoid injury, do not touch the fan with your hands or any tools as you slide the fan module out of the chassis—the fan might still be running.
- When the fan stops rotating, slide the fan module completely out of the chassis.
- Place the fan module in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
