APC Guide to Factory Reset, SSH Commands, and Telnet Options for PDU

Switched Rack PDU

USER’S GUIDE

®

FTP transfers files without using encryption. For higher security, use Secure CoPy (SCP) for file transfers. When you select and configure Secure SHell (SSH), SCP is enabled automatically. To configure SSH, see Telnet/SSH. If you decide to use SCP for file

transfer, be sure to disable the FTP server.

Use the Port setting to identify the TCP/IP port that the FTP server uses for communications with the Rack PDU. The default Port setting is 21.

You can change the Port setting to any unused port from 5000 to 32768 to enhance the protection provided by User Name and Password settings. You must then use a colon (:) in the command line to specify the non-default port. For example, for a port number of 5000 and a Rack PDU IP address of 159.215.12.114, you would use this command:

ftp 159.215.12.114:5000

To access a text version of the Rack PDU’s event or data log, see How to use FTP or SCP to retrieve a log file.

Telnet/SSH

Use the Telnet/SSH option to perform the following tasks:

•Enable or disable Telnet or the Secure SHell (SSH) protocol for remote control console access.

–While SSH is enabled, you cannot use Telnet to access the control console.

–Enabling SSH enables SCP automatically.

When SSH is enabled and its port and encryption ciphers configured, no further configuration is required to use SCP. (SCP uses the same configuration as SSH.)
