Replace a power/cooling module in a SAS expansion enclosure Take the following actions to remove the faulted power/cooling module from the SAS expansion enclosure and install a replacement power/cooling module. Identify a faulted power/cooling module from PowerStore Manager Before you replace a power/cooling module, ensure that you have identified its location within the system. Using PowerStore Manager, you can identify and locate a faulted power/cooling module. Steps 1. From PowerStore Manager, select Hardware. 2. Select the appliance that contains the power/cooling module that you need to replace. 3. On the Components card, under Rear View, expand ExpansionEnclosure. 4. Select the relevant PSU. Faulted parts appear in red in the image of the system, and report a status of Faulted in the State field. Removing a faulted power/cooling module Prerequisites Identify the faulted power/cooling module by the amber fault LED. CL5987 Figure 154. Fault LED on an AC power/cooling module About this task CAUTION: Access to the drives in your enclosure will time out and the drives will spin down two minutes after a power cooling module is removed from the enclosure. While the system can continue operating on a single power supply, the loss of two blowers causes the DAE to power down unless you replace the module within two minutes. When replacing both cooling modules, ensure that the green light on one module has been steadily on for at least 5 seconds before removing power from the second module. Steps 1. Attach an ESD wristband to your wrist and the enclosure. 2. On an AC power/cooling module, release the cable retention bail, and unplug the power cord.
