GE Multilin D30 Line Distance Protection System 5-175 SETTINGS 5.2 PRODUCT SETUP5The Supervisory menu settings are available for Supervisor role only or if the Supervisor role is disabled then for theAdministrator role only.Figure 5–2: SUPERVISORY PANELLocal Authentication: This setting is enabled by default, meaning "Yes" is selected. When enabled, Device Authenticationwith roles is enabled. When this setting is disabled, the UR only authenticates to the AAA server (Radius). However, theAdministrator and Supervisor (when enabled) remain active even after device authentication is disabled and their only per-mission is to re-enable device authentication. To re-enable device authentication, the Supervisor unlocks the device for set-ting changes, then the Administrator re-enables device authentication.Bypass Access: Enabling this setting allows 502 Ethernet sessions to the relay. The serial ports (RS232 and RS485) allowsettings write. No passwords or roles are required when in this mode. When disabled, everything goes back to normal. Thissetting has no effect on the front panel and it continues to support Role Based Access Control (RBAC).Lock Relay: This setting uses a Boolean value (Enable/Disable) to indicate if the device accepts setting changes andwhether the device can receive a firmware upgrade. This setting can be changed only by the Supervisor role, if it is enabledor by the Administrator if the Supervisor role is disabled. The Supervisor role enables this setting for the relay to startaccepting setting changes or command changes or firmware upgrade. After all the setting changes are applied or com-mands executed, the Supervisor disables to lock setting changes.Example: If this setting is "Yes" and an attempt is made to change settings or upgrade the firmware, the UR device deniesthe setting changes and denies upgrading the firmware. If this setting is "No", the UR device accepts setting changes andfirmware upgrade.This role is disabled by default.MODE SERIAL (RS232 & RS485) 502 ETHERNET SSH ETHERNETBypass Access = Disabled Local Authenticationand Role Based AccessControl (RBAC)and passwords in clearRead only Local/Remote Authenticationand Role Based Access Control (RBAC)and passwords encryptedBypass Access = Enabled No Role Based Access Control(RBAC)and no passwordsNo Role Based AccessControl (RBAC)and no passwordsLocal/Remote Authenticationand Role Based Access Control (RBAC)and passwords encrypted
