Access Priorities for Logging on

Only one user at a time can log on to the Rack PDU. The priority for access, beginning with the highest priority, is as follows:

•Local access to the command line interface from a computer with a direct serial connection to the Rack PDU

•Telnet or Secure SHell (SSH) access to the command line interface from a remote computer

•Web access, either directly or through StruxureWare Data Center Expert

Note: See “SNMP” on page 87 for information about how SNMP access to the Rack PDU is controlled.

Types of User Accounts

The Rack PDU has four levels of access (Administrator, Device User, Read-Only User, and Outlet User), which are protected by user name and password requirements.

•An Administrator can use all of the menus in the Web interface and all of the commands in the command line interface. The default user name and password are both apc.

•A Device User can access only the following:

–In the Web interface, the menus on the Device Manager tab, the Environment tab, and the event and data logs, accessible under the Events and Data headings on the left navigation menu of the Logs tab. The event and data logs display no button to clear the log.

–In the command line interface, the equivalent features and options. The default user name is device, and the default password is apc.

•A Read-Only User has the following restricted access:

–Access through the Web interface only.

–Access to the same tabs and menus as a Device User, but without the capability to change configurations, control devices, delete data, or use file transfer options. Links to configuration options are visible but disabled. The event and data logs display no button to clear the log.

The default user name is readonly, and the default password is apc. To set User Name and Password values for the three account types above, see “Setting user access” on page 77.

•An Outlet User has the following restricted access:

–Access through the Web interface and command line interface.

–Access to the same menus as a Device User, but with limited capability to change configurations, control devices, delete data, or use file transfer options. Links to configuration options are visible but are disabled. The Outlet User has access to the Outlet Control menu option that allows the user to control the outlets assigned by the Administrator. Outlet Users cannot clear the event or data logs.

The user name and password are defined by the Administrator during the process of adding a new Outlet User.
