Switched Rack PDU

Access Procedures
Overview
The Switched Rack PDU has two internal interfaces (control console and
Web interface) that allow you to manage the Rack PDU.
The SNMP interface also allows you to use an SNMP browser with the
PowerNet® Management Information Base (MIB) to manage the Rack
PDU.

Access priority for logging on

Only one user at a time can log on to the Rack PDU to use its internal user
interface features. The priority for access is as follows:
• Local access to the control console from a computer with a direct serial
connection to the Rack PDU always has the highest priority.
• Telnet or Secure SHell (SSH) access to the control console from a
remote computer has priority over Web access.
• Web access, either directly or through the InfraStruXure Manager, has
the lowest priority.
For more information about the internal user interfaces, see
Control Console and Web Interface.
