Switched Rack PDU
54
APC supports the authentication and authorization functions of RADIUS (Remote
Authentication Dial-In User Service).
• When a user accesses the Switched Rack PDU or another network-enabled device
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 Switched Rack PDU are limited to 32 characters.
Select one of the following:
• Local Authentication Only: RADIUS is disabled. Local authentication is enabled.
• RADIUS, then Local Authentication: RADIUS and local authentication are enabled.
Authentication is requested from the RADIUS server first. If RADIUS authentication
fails, local authentication is used
.
• RADIUS Only: RADIUS is enabled. Local authentication is disabled.
Caution
If RADIUS Only is selected, and the RADIUS server is unavailable,
improperly identified, or improperly configured, you must use a serial
connection to the control console and change the Access setting to Local
Authentication Only or RADIUS, then Local Authentication to regain
access.
