NOTICE:
Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal

NOTICE:
Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not

aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
