AC or DC AC or DC WrongWayFeldman (IS/IT--Management) (OP) 11 Mar 18 14:57 How can I tell if a cs1000 is an AC switch or a DC switch from command line in a telnet session to the PBX? RE: AC or DC KCFLHRC (TechnicalUser) 12 Mar 18 14:02 I cant think of any way to do that right off hand. But a monkey in front of the PBX can remove 1 cover and tell you by looking at the Power Supplies. RE: AC or DC WrongWayFeldman (IS/IT--Management) (OP) 13 Mar 18 11:02 Do you know the part numbers for an AC Power supply and a DC power supply so I can look up some pictures? Also, do you know where I can rent a monkey? RE: AC or DC KCFLHRC (TechnicalUser) 14 Mar 18 16:16 Probably the easiest way to tell for the monkey is to look at the lower back of a pedestal and see if there are 5 individual breakers, that would indicate a DC switch as well have him look for the presence of a battery string or a rectifier.
