Removing and replacing components

Use this information to remove and replace components of the Flex System Carrier-Grade 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 Carrier-Grade chassis.

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