Power Supply Failure

If either of the two redundant power supply modules fail, the other module will take over without service interruption. The UID LED on the front panel (see Front Panel Overview) will blink slowly until the failed module has been replaced.

Do not user power supplies other than the original model installed in the unit. Replacement power supplies can be procured directly from Spectracom (part no. PS09R-070J-SL01), or from the OEM manufacturer, Supermicro Computer (model PWS-651-1R).
