Reference Information:

Part Number Information can be found using the System Handbook:

Sun System Handbook

Sun Fire[tm] T2000 Server / Sun Fire[tm] T2000 Server, RoHS:YL ( 541-0645 [C] Rear Fan Tray )

Recommended Action:

Open a service request by one of the following methods:

Use My Oracle Support to open the service request using active CSI# for the system.

Call Oracle directly using 1-800-223-1711 and follow prompts to open the service request

T2000 blower tray: 541-0645 uses an open bearing fan that can fail at elevated failure rates after 2-3 years in the field which can

degrade over time leading to fan failure. The failure rates seen can vary based on a number of environmental factors such as data

center cooling, air quality, humidity levels, etc. Fix is to replace failed units with replacement P/N 541-0645 from the RSL stock. If

a customer has concerns or has experienced excessive failures contact Product Lead [email protected]

or Engineering's [email protected] for assistance.
