Configuring the Product b. At the R_A_TOV field, type a value between 10 through 1200 tenths of a second (1 through 120 seconds). (The R_A_TOV value must be greater than the E_D_TOV value.) Note: If the product is attached to a fabric element, the product and element must be set to the same R_A_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric. c. At the E_D_TOV field, type a value between 2 through 600 tenths of a second (0.2 through 60 seconds). (The E_D_TOV value must be less than the R_A_TOV value.) Note: If the product is attached to a fabric element, the product and fabric element must be set to the same E_D_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric. d. Choose from the Switch Priority drop-down list to set the product priority. Available selections are Default, Principal, and Never Principal. The default setting is Default. This value designates the fabric's principal switch. The principal switch is assigned a priority of 1 and controls the allocation and distribution of domain IDs for all fabric elements (including itself). Principal is the highest priority setting, Default is the next highest, and Never Principal is the lowest priority setting. The setting Never Principal means the switch is incapable of becoming a principal switch. If all switches are set to Principal or Default, the switch with the highest priority and the lowest World Wide Name (WWN) becomes the principal switch. At least one switch in a fabric must be set as Principal or Default. If all switches are set to Never Principal, all interswitch links (ISLs) will segment, causing a failure of connectivity. e. Choose from the Interop Mode drop-down list to set the product operating mode. This option does not display if the operation mode is S/390. (S/390 mode is not supported with the Edge Switch 2/24.) 36 Embedded Web Server User Guide
