Hi, What model switches are in the stack? You can try the connect command. Page 2202 [URL] Alternatively you may be able to access management with the IP of a VLAN.
We have a stack at a remote site that had a failure and rebooted, the OOB and console cable were only plugged into that unit, when it rebooted, the stack initiated a failover to another member, is there a way to "tunnel" through the stack member now to the new stack master?  I get teh message "(Unit 2 - CLI unavailable - please connect to master on Unit 4)" when I try to access console.  It is a remote site or I would just go and plug into the new Master switch.    
Stack master died at remote site, any chance to manage this when the CLI is 
unavailable?
