This chapter explains how to use the Command Line Protocol (CLP) interface to administer an
Revelation PDU.
#4' $
The Revelation PDU provides a command line interface that enables data center administrators to
perform certain basic management tasks. You can access the interface over a serial connection
using a terminal emulation program such as HyperTerminal, or via a Telnet or SSH client such as
Putty.
Note: Telnet access to the Revelation PDU is disabled by default because Telnet transmits in the
clear and is insecure. To enable Telnet, select Device Settings  Network and click the check
box labeled Enable CLP-Telnet Access.
The command line interface is based on the Systems Management Architecture for Server
Hardware (SMASH) Command Line Protocol (CLP). Using this interface, you can do the
following:
• Display the name, power state (on or off), and sensors associated with each Revelation PDU
outlet
• Turn each outlet on or off
• Display the status of the sensors associated with each outlet

Logging in via HyperTerminal and a serial connection is a little different than logging in using
SSH or Telnet.

To log in using HyperTerminal:
1. Launch HyperTerminal and open a console window. When the window first appears, it is
blank.
2. Press Enter to display a Command prompt.

3. At the Command prompt, type CLP and press Enter. You are prompted to enter a login
name. The login name is case-sensitive, so make sure you capitalize the correct letters.
