This document describes replacement procedures for the fan module customer replaceable unit (CRU) installed in the Sun Storage J4200 Array disk tray. This document assumes you have:
- Identified the failed fan module.
- Received the replacement fan module.
This product is intended for restricted access whereby access is controlled through the use of a means of security (e.g., key, lock, tool, badge access), and personnel authorized for access have been instructed on the reasons for the restrictions and any precautions that need to be taken.
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.
