USER’S GUIDE
Switched Rack PDU
78
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
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.
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.
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.
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.)
