Figure 5. Major FRUs and CRUs
The following table lists the major FRUs and CRUs shown in Figure 5 "Major FRUs and CRUs" on page 35
and identifies which CRUs are self-service CRUs or optional-service CRUs.
Notes:
• Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by
trained service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill
level. Trained service technicians can also provide service to install or replace the parts under the type of
warranty designated for the customer's machine.
• FRUs: Refer to parts that must be installed or replaced only by trained service technicians. If customers
choose to replace the FRUs by themselves, the product warranty might be affected.
