Log on to the existing Nortel SNAS 4050 device to check the software version and 
system settings. Use the 

 command to check the currently 

installed software version (for more information, see 

). Use the 

 command to view settings for the Access List (for more 

information, see 

). 

Do not proceed with the join operation until the following requirements are met.

•

Verify that the IP addresses you will assign to the new Nortel SNAS 4050 
device conform to Nortel SNA network requirements. For more information, 
see 

•

The Access List has been updated, if necessary. 

The Access List is a system-wide list of IP addresses for hosts authorized to 
access the Nortel SNAS 4050 devices by Telnet and SSH. 

If the 

 command executed on the existing Nortel SNAS 4050 

shows no items configured for the Access List, no action is required. 
However, if the Access List is not empty before the new Nortel SNAS 4050 
joins the cluster, you must add to the Access List the cluster’s MIP, the 
existing Nortel SNAS 4050 RIP on Interface 1, and the new Nortel 
SNAS 4050 RIP on Interface 1. You must do this before you perform the join 
operation, or the devices will not be able to communicate with each other. 

For information about adding entries to the Access List, see 

•

The existing Nortel SNAS 4050 and the new Nortel SNAS 4050 must run the 
same version of software. If the versions are different, decide which version 
you want to use and then do one of the following:

•

To change the version on the new NSNAS, download the desired software 
image and reinstall the software (see 

).
