You could give each user permission to reset their port and consolidate to a larger PDU. You could also set warning thresholds to send to your pager through your monitoring system which collects SNMP traps. (it also has an API so you could hook-in to a web form if you want to code it yourself and manage what they see based upon their clientID or such)
Geist may have a less expensive, more customizable option to suit your needs. You spend a little more upfront for the larger rackmount pdu, but certainly not $200 per user. _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
