6.3 Upgrade of software by remote

When a terminal is connected to the switch by a network, software can be upgraded
remotely.

6.3.1 Upgrade of software by FTP

Carry out the FTP server as which the user name, a password and a file directory are set
right on the local end. An IP address of a terminal is 10.10.110.1. Log on to the switch via
Telnet and send a host program to the switch using a FTP.
The software program is made SWITCH.app. After logging on to the switch using Telnet,
follow the next procedure.
1) Download the software to the switch using FTP.
<QX> ftp 10.10.110.1

2) Specify the software used at next-startup.
<QX> boot-loader file SWITCH.app slot 1 main
<QX> display boot-loader
The main boot app is: flash:/SWITCH.app
<QX> reboot
Before restarting the switch, make sure other configurations are all saved to avoid the loss
of configuration information.
Therefore specification of the software used at next-startup is completed. To confirm the
upgrade of software, restart the switch. After a load of Boot Rom has been completed when
space of a flash memory isn't enough, it's possible to delete several files in the flash
memory. It's recommended to delete the software which isn't used. Upload software using a
FTP. Power interruption is not allowed during software loading.

6.3.2 Upgrade of software by TFTP

The remote loading by using TFTP is similar to the remote loading by using FTP. The only
difference is that it is TFTP that you use when loading software to the switch. In this case,
the switch can only be used as a TFTP client. The remaining step after download is just
same as the occasion of the remote load with a FTP.
