In one embodiment, a method using an automated infrastructure management system comprising a portable device, a management system and a secured equipment cabinet comprises: scanning an asset ID tag with the portable device to obtain asset ID data; transmitting the asset ID data to the management system; verifying whether the asset ID data is associated with an electronic lock identified by an electronic work order, where the work order defines tasks involving a network device within the cabinet; scanning a fingerprint with the portable device to obtain fingerprint ID data; and verifying whether the fingerprint ID data matches an authorized technician. When the asset ID data is verified as associated with the electronic lock and the fingerprint ID data is verified as matching the authorized technician, sending an electronic command from the management system that unlocks the electronic lock.
