Major FRUs and CRUs
Your computer contains the following types of CRUs and FRUs:
• Self-service CRUs: Refer to parts that can be replaced easily by customer themselves or by trained
service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be replaced by customers with a greater skill level.
Trained service technicians can also provide service to replace the parts under the type of warranty
designated for the customer’s machine.
• FRUs: Refer to parts that must be replaced only by trained service technicians. If customers choose to
replace the FRUs by themselves, the product warranty might be affected.
