Put UPS on Bypass
Use the Put UPS on Bypass option of the Diagnostics menu to put a Symmetra Power Array or Matrix-UPS into bypass mode so that you can perform maintenance. In bypass mode, the UPS functions only as a voltage conditioner and provides protection from power surges but not power sags, brownouts, or blackouts.
After you select it, the menu option changes to Take UPS off Bypass so that you can return the Symmetra Power Array or Matrix-UPS to normal operation when you complete the maintenance.
If your Symmetra Power Array is running with a main intelligence module only or with a redundant intelligence module only, you can use PowerChute plus to put your UPS in Bypass Mode to replace that part while briefly relying on utility power only. (If your Symmetra Power Array is running with both a main intelligence module and a redundant intelligence module, you can replace either part while the UPS continues to support the attached equipment.)
Caution:
To support its equipment load in bypass mode that you initiate through PowerChute plus, a Symmetra Power Array must have either a functioning main intelligence module or a functioning redundant intelligence module. Only if you use the manual switch to put a Symmetra Power Array into bypass mode can you safely remove both the main intelligence module and redundant intelligence module at the same time for maintenance.
