Option	Description
Telnet/SSH Network Configuration
Access	Enables or disables the access method selected in Protocol Mode.
	NOTE: Enabling SSH automatically disables Telnet. To enable SSH,
	change the setting and then click Next>> in the Web interface or choose
	Accept Changes in the control console. You must then agree to the
	license agreement that is displayed.
Protocol	Choose one of the following:
Mode	• Telnet: User names, passwords, and data are transmitted without
	encryption.
	• Secure SHell (SSH), version 1: User names, passwords, and data are
	transmitted in encrypted form. There is little or no delay when you are
	logging on.
	• Secure SHell (SSH), version 2: User names, passwords, and data are
	transmitted in encrypted form, but with somewhat more protection than
	version 1 from attempts to intercept, forge, or alter data during data
	transmission. There is a noticeable delay when you are logging on to
	the Battery Management System.
	• Secure SHell (SSH), versions 1 and 2: Do not enable both versions of
	SSH unless you require that both be activated at the same time.
	(Security protocols use extensive processing power.)
