Chapter 7 – Configuring Frame Relay/PPP And T3
Upgrading Software
For some customers, access to remote sites in accomplished solely by a T3
connection. Usually a software upgrade will stop the system being upgraded,
perform the upgrade and then restart it. If T3 port was upgraded in this way, the
upgrade would fail as the T3 link was taken down. Instead, T3 software upgrades
modify only the software on the disk. You must schedule a reboot in order to run the
new version of T3 software.
