How to Distinguish the Power Modules of the Controller Enclosure and Disk Enclosure of the S5100 from the Appearance?

Publication Date:  2012-07-20 Views:  43 Downloads:  0
Issue Description
The power modules of the S5100 controller enclosure and disk enclosure are almost the same on size and appearance. The power module of the S5100 controller enclosure has the management function, while the power module of the S5100 disk enclosure does not have the function. Therefore, the two power modules must be correctly used. Pay attention to their difference when you replace spare parts.

Handling Process
Step 1  If a power module has been inserted in the enclosure, check the power parameter on the enclosure. The input power of the power module with the management function is 8 A, while the input power of the power module without the management function is 7 A.
Step 2  If a power module is removed from the enclosure, judge it by the module code. The method is as follows:

02130574 is the power module with the management function.
02130604 is the power module without the management function.
Step 3  Distinguish the power modules by weight. The power module with the management function is heavier than the one without the management function
