Removing and replacing components

Use this information to remove and replace components of the Flex System Enterprise Chassis.

Replaceable components consist of consumable parts and field replaceable units (FRUs):
  • Consumable part: Purchase and replacement of consumable parts (components, such as batteries and printer cartridges, that have depletable life) is your responsibility. If Lenovo acquires or installs a consumable part at your request, you will be charged for the service.
  • Field replaceable unit (FRU): FRUs must be replaced only by a trained service technician, unless they are classified as customer replaceable units (CRUs).
    • Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo installs a Tier 1 CRU at your request without a service contract, you will be charged for the installation.
    • Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request Lenovo to install it, at no additional charge, under the type of warranty service that is designated for your Flex System Enterprise Chassis.

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