Servicing SAS Cables
This section describes how to service SAS cables.
SAS interface cables are replaceable components that require you to power off the server
before servicing. For more information about replaceable components, see Illustrated Parts
Breakdown and Replaceable Components.
Caution:
The system supplies power to the cables even when the server is powered off. To
avoid personal injury or damage to the server, you must disconnect power cords
before servicing the cables.
Caution:
These procedures require that you handle components that are sensitive to
electrostatic discharge. This sensitivity can cause the component to fail. To avoid
damage, ensure that you follow electrostatic discharge safety measures and
antistatic practices. See Electrostatic Discharge Safety.
