Nortel Networks 4050 manual Before you begin

62Chapter 2 Initial setup

Before you begin

Log on to the existing Nortel SNAS 4050 device to check the software version and system settings. Use the /boot/software/cur command to check the currently installed software version (for more information, see “Managing software for a Nortel SNAS 4050 device using the CLI” on page 734). Use the /cfg/sys/ accesslist/list command to view settings for the Access List (for more information, see “Configuring the Access List using the CLI” on page 474).

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 “About the IP addresses” on page 51 and “One-armed and two-armed configurations” on page 40.

•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 /info/sys 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 “Configuring the Access List using the CLI” on page 474.

•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 “Reinstalling the software” on page 763).
