A SNMP network comprises a power manager with a SNMP agent in TCP/IP communication over a network with a SNMP network manager. The power manager is connected to control several intelligent power modules each able to independently control the on/off power to several inter-networking devices in an equipment rack at a common remote node, e.g., a point-of-presence site. Power-on and load sensors within each intelligent power module are able to report the power status of each inter-networking device to the SNMP network manager with MIB variables in response to GET commands. The SNMP network manager is further able to reboot each inter-networking device by cycling the power on/off to its respective intelligent power module with the SET command provided in conventional SNMP management applications. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG.
1 illustrates a simple network management protocol (SNMP) network embodiment of the present invention, referred to herein by the general reference numeral 10.
The SNMP network 10 includes a host 12 with a TCP/IP connection 14 to a plurality of point-of-presence (POP) nodes represented by a pair of equipment racks 16 and 18.
SNMP network management is provided by a SNMP manager 20 in communication with a respective pair of SNMP agents 22 and 24 at the remote nodes.
The SNMP manager 20 may comprise a commercial product such as IBM NETVIEW/6000, HP OPENVIEW, POLYCENTER, SunNet MANAGER, Cabletron SPECTRUM, etc.
Each POP node can be associated with an uninterruptable power supply (UPS) 26 that provides operating power to a TCP/IP-addressable enterprise power manager 28 and several intelligent power modules 30, 32, 34, 36 connected to corresponding inter-networking devices 38, 40, 42, 44.
An SNMP agent 46 is private to the power manager 28 and does not depend on the equipment rack 16 or its inter-networking devices 38, 40, 42, 44.
The power manager 28 is connected to independently control each of the intelligent power modules 30, 32, 34, 36.
Such control includes being able to sense the power-on and load status of each of the inter-networking devices 38, 40, 42, 44 and to switch power on and off to each of the inter-networking devices 38, 40, 42, 44.
Such status is sensed and reported by an SNMP GET command 48 and the power switching is accomplished with an SNMP SET command 50 that issue from the host 12.
FIG.
2 shows a method of appliance power switch status detection, referred to herein by the general reference numeral 100.
The method 100 comprises a step 102 applying a series of alternating current (AC) voltage pulses to an appliance with an on/off switch that are synchronized to a source of AC power.
A step 104 senses the presence of any series of AC current pulses that result if the appliance switch is closed.
A step 106 analyzes any AC current pulses detected in step 104 to determine if they resulted from the application of the AC voltage in step 102
