In a PowerProtect DD system, when setting up expansion shelves, the cabling follows a specific sequence to ensure proper communication between the controller and the shelves. The host port on the last shelf in the chain is connected to the expansion port of the controller to complete the loop. This ensures that data flows correctly between the controller and all shelves in the chain.

See the solution in the explanation below.
Explanation:
To create a new non-admin user and a storage unit for an Oracle department on PowerProtect DD, follow these steps:
Step 1: Create the User "DDBoostOracle"
* Navigate to the User Management Section:
* Look under Administration or Users in the sidebar (the exact location may vary by DD OS version).
* Create New User:
* Click on Add User or New User.
* Enter Username: DDBoostOracle
* Enter Password: Password123
* Set Management Role to None.
* Set Password Aging Policy:
* Set Minimum Days: 0
* Set Maximum Days: 180
* Set Warn Days: 15
* Assign the User to DD Boost Users Group:
* Locate the option to assign the user to groups and select the ddboost users group.
* Save User Configuration:
* Confirm and save the settings to create the user.
Step 2: Create the Storage Unit "SU_Oracle"
* Navigate to DD Boost Protocol:
* Go to Protocols > DD Boost in the sidebar.
* Create a New Storage Unit:
* Find Storage Units and select Add Storage Unit.
* Name the storage unit as SU_Oracle.
* Assign the User to the Storage Unit:
* During the creation process or in the access settings of the storage unit, assign DDBoostOracle as the user with access.
* Save Storage Unit Configuration:
* Confirm and save the configuration to ensure that the new user has access to the storage unit.
This completes the setup for a non-admin user with the specified password aging policy and a dedicated storage unit for the Oracle department. Let me know if additional steps are needed!
