RMA replacement for HA pair

Question

Hi, 
 
 I have just received an RMA replacement for a secondary unit that died and was part of a HA pair. 
 What are the steps that I need to replace this unit. 
 I am struggling to log on to it with admin/admin, is this the wrong logon? 
 I can see that I need to get the software on the same version, then do I just add it to the HA setup on the primary unit?
