Removing and replacing components

There are four types of replaceable components.

  • Consumables: Purchase and replacement of consumables (components, such as batteries and printer cartridges, that have depleting life) is your responsibility. If IBM acquires or installs a consumable component at your request, you will be charged for the service.
  • Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for the installation.
  • Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request IBM to install it, at no additional charge, under the type of warranty service that is designated for your server.
  • Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.

See Parts listing, Lenovo System x3550 M3 Type 4254 and 7944 to determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU.

For information about the terms of the warranty, see the Warranty Information document that comes with the server.
