    Hello Hosein. The main alarm on this unit is the low suction pressure alarms. Can you get the pressures (suction and discharge) off the unit's web interface or the front screen? Also, is this unit in a group or a lead/lag setup?

    Thank you

    Hello. I have copied in the link to our knowledge base on our website below that will give you the three ways to upgrade the firmware on the network management cards (NMC). This unit has an NMC2 in it, so follow the directions for the NMC2.

    Thank you


    How do I upgrade the firmware on an APC Network Management Card (NMC) or NMC embedded device (Rack PDU, etc)?
