Move the pointer over the part for a description. Click the part to locate the part number.

Notes: If your specific model is not listed, please enter the product number on the Support & downloads home page, and refer to the product description. Look for the "Based on" model.

Note: Each Field Replaceable Unit (FRU) applies to all types and models, unless specific types or model numbers are listed with the FRU.

FRUs that have a 1 or 2 in the CRU column are Customer Replaceable Units (CRUs).
- 1 identifies parts that are fairly simple to replace, requiring few or no tools.
- 2 identifies parts that are slightly more difficult to replace.
- N identifies parts that are not to be replaced by the customer.
RoHS compliance:
- Parts identified by an R in the RoHS ID column are compliant.
- Parts identified by an N in the RoHS ID column are not compliant.
