Remote Users

Authentication

Use this option to select how to administer remote access to the cooling unit:

For information about local authentication (authentication that can be administered without the centralized authentication provided by a RADIUS server), see the Security Handbook provided on the Utility CD and available on the APC Web site at www.apc.com.

Note: APC supports the authentication and authorization functions of RADIUS (Remote Authentication Dial-In User Service).

•When a user accesses the cooling unit that has RADIUS enabled, an authentication request is sent to the RADIUS server to determine the user’s permission level.

•RADIUS user names used with the cooling unit are limited to 32 characters.

Select one of the following:

•Local Device Only: RADIUS is disabled. Local authentication is enabled.

•RADIUS, then Local Device: RADIUS is enabled, and local authentication is enabled. Authentication is requested from the RADIUS server first; local authentication is used only if the RADIUS server is not available.

•RADIUS Only: RADIUS is enabled. Local authentication is disabled.

Note: If RADIUS Only is selected, the only way to recover if the RADIUS server is unavailable, improperly identified, or improperly configured is to use a serial connection to the control console and change the Access setting to Local Device Only or RADIUS, then Local Device. See “Local access to the control console” on page 7 for information about how to access the serial port.

RADIUS

Use this option to do the following:

•Display a list of RADIUS servers identified as being available to the cooling unit and the time-out period for each server (the number of seconds the cooling unit will wait for a reply from the server before the request fails).

•Add a server to the list of identified RADIUS servers. Click Add Server, and configure the following parameters for authentication by the new server:
