BOOTROM AND HOST SOFTWARE

Traditionally, the loading of switch software is accomplished through a serial port.

This approach is slow, inconvenient, and cannot be used for remote loading. To

resolve these problems, the TFTP and FTP modules are introduced into the switch.

With these modules, you can load/download software/files conveniently to the

switch through an Ethernet port.

This chapter introduces how to load BootROM and host software to a switch

locally and how to do this remotely.

Introduction to

Loading Approaches

You can load software locally by using:

■ XMODEM through Console port

■ TFTP through Ethernet port

■ FTP through Ethernet port

You can load software remotely by using:

■ FTP

■ TFTP

The BootROM software version should be compatible with the host software

version when you load the BootROM and host software.

Local Software

If your terminal is directly connected to the switch, you can load the BootROM and

host software locally.

Before loading the software, make sure that your terminal is correctly connected

to the switch to insure successful loading.

The loading process of the BootROM software is the same as that of the host

software, except that during the former process, you should press <Ctrl+U> and

<Enter> after entering the Boot Menu and the system gives different prompts. The

following text mainly describes the BootROM loading process.
