NOTE: Removing the ACM also removes the battery pack. If the controller is not currently in conservative cache mode, once the ACM is removed, it will go into con- servative cache mode. See the Dell OpenManage Array Manager documentation for information on troubleshooting the battery.
To remove an ACM, perform the following steps:
1.Ensure that access to the faulty advanced cooling module is not restricted by power cords or cables.
2.Unscrew the captive screws that secure the ACM in its slot.
3.Pull the cooling module out of its slot and set it down on a smooth surface, upside down.
