Option Description

SSH User Host Key File

Status	The Status field indicates the status of the host key (private key). In the
	control console, you display host key status by selecting Advanced SSH
	Configuration.
	• SSH Disabled: No host key in use: No host key has been transferred
	to the Battery Management System, or a host key has been transferred
	improperly.
	NOTE: A host key must be installed to the /sec directory of the Battery
	Management System
	• Generating: The Battery Management System is generating a host key
	because no valid host key was installed in its /sec directory.
	• Loading: A host key is being loaded (i.e., being activated on the Battery
	Management System).
	• Valid: The host key is valid. (If you install an invalid host key, the
	Battery Management System discards it and generates a valid one.
	However, a host key that the Battery Management System generates is
	only 768 bits in length. A valid host key created by the APC Security
	Wizard is 1024 bits.)
Filename	You can create a host key file with the APC Security Wizard and then
	upload it to the Battery Management System by using the Web interface.
	Use the Browse button for the Filename field to locate the file, then click
	Apply.
	Alternatively, you can use FTP or Secure CoPy (SCP) to transfer the host
	key file to the Battery Management System.
	NOTE: Creating and uploading a host key in advance reduces the time
	required to enable SSH. If no host key is loaded when you enable SSH,
	the Battery Management System creates one when it reboots. The
	Battery Management System takes up to 5 minutes to create this
	key, and the SSH server is not accessible during that time.
