Serial Interface Operation

Serial Interface Operation

This section describes remotely configuring and monitoring a Dell Metered Rack Power Distribution Unit
(rPDU) through the serial interface connection between the rPDU internal Dell Network Management Card
(NMC) and a laptop or workstation.

Access to a command line interface (CLI) using an Avocent protocol is provided through a terminal emulation
program, such as HyperTerminal or Telnet.

NOTE:

A terminal emulation program can communicate with another computer or network as if it were a specific type of

terminal directly connected to that computer or network.

Once connected, you can perform basic configuration and monitoring tasks for the rPDU to which you are
connected, including the following:

Retrieve selected meters and measurements, including current, present power, temperature, and input
voltage

Set or retrieve rPDU critical alarm high threshold values

Set or retrieve high temperature warning or alarm threshold values, and low humidity warning or alarm
threshold values

Set or retrieve settings for dry contact sensors connected to the rPDU

Retrieve selected rPDU equipment, software version, and ratings information

Reset the rPDU settings to factory defaults or reboot the rPDU

NOTE:

The rPDU defaults to using DHCP when delivered. If you are unable to connect to the rPDU through the network

connection with this default address, change the IP address using the serial interface before using any of the network
interfaces.

Supported Commands

The rPDU serial interface command set for managing and monitoring the rPDU includes the following
commands:
