Unable to backup Cisco SG500X

Unable to backup Cisco SG500X

  I am using the NCM plugin for Opmanager and I am unable to complete a backup on my Cisco SG500X.
  I have both SSH and SNMP credentials set up and are passing credential tests.  My Credential Status setting is SSH.  On the Test Credential page it shows that it is able to run the show running-config command but stops at the end of the page (More , Quite: q or CTRL+Z, One line:).  Under the execution output for the backup, it shows:

"Entered into the enable login mode successfully. terminal length 0 null"

  I believe this could be the issue as the SG500 series does not have the "terminal length 0" command.  I have been researching and I cannot find a way to turn off the pagination on the SG500.
  Is there another way that will work for backups?
