NOTES:
- Each FRU is available for all types/models, unless specific types or models are given.
- The parts that are CRUs (customer replaceable units) are identified by a N, 1 or 2 in the CRU column.
- N indicates the part is not a CRU.
- 1 indicates the part is a Tier 1 CRU. An example of a Tier 1 CRU would be a mouse, external keyboard, and hard disk drive with coin screw
- No tools required.
- Coin, thumbscrews acceptable
- Minimal technical expertise required
- Minimal problem determination (less than 5 minutes)
- 2 indicates the part is a Tier 2 CRU. An example of a Tier 2 CRU would be an adapter card, and memory.
- Maximum of 4 screw/fastener removals
- Some technical experience required
- Support Center assistance may be used
- Problem determination can be done by customer either on site or with Support Center assistance.
