ESD Precautions

When performing this service action, observe the following electrostatic discharge (ESD) precautions:

• Wear an antistatic wrist strip at all times when handling any CRU.
• Before handling any CRU, discharge any static electricity by touching a grounded surface.
• Remove all plastic, vinyl, and foam material from the work area.
• Do not remove a CRU from its antistatic protective bag until you are ready to install it.
• After removing a CRU from the cabinet, immediately place it in an antistatic bag or antistatic packaging.
• Handle any card CRU only by its edges and avoid touching the components or circuitry.
• Do not slide a CRU over any surface.
• Limit body movement (which builds up static electricity) during the removal and replacement of a CRU.

This section describes how to remove and replace a fan module.

Caution - The power supplies in this equipment can produce high energy hazards. Only personnel with authorized access to this equipment should remove and replace modules in the system.

1. Locate the failed fan module.

The Fan status LED is amber. (See FIGURE 2.)

Caution - Potential loss of data access - Never remove a fan module unless the Cooling module status LED is amber. Data loss could occur if one fan module fails and you inadvertently remove the operational fan.
