The first activity in every recovery plan is damage assessment, immediately followed by damage mitigation.
This first activity would typically include assessing the damage to all network and server components (including cables, boards, file servers, workstations, printers, network equipment), making a list of all items to be repaired or replaced, selecting appropriate vendors and relaying findings to Emergency Management Team.
Following damage mitigation, equipment can be recovered and LAN communications network and servers can be reinstalled.
