Why is the Electronic Serial Number field blank?
A. It is blank because it was not set in the device software when the device was introduced to the network. Update the number using the CLI, as described in the device configuration guide. Inventory populates the Managed Serial Number using SNMP to get the MIB serial number information from the Electronic Serial Number setting. If the Managed Serial Number field is blank, the inventory collector could not collect the information for one of these reasons: •The Electronic Serial Number field is not set. You can set this field by using the CLI as described in the device configuration guide, and update the inventory database by selecting Resource Manager Essentials > Inventory> Administration > Change Device Attributes. •The device does not support MIBs for serial numbers. Select Resource Manager Essentials > Inventory > Administration > Change Device Attributes to enter the information in inventory.
