10Download software to appropriate switch fabric modules and interface modules in any order.

 

CAUTION: Downloaded software does not become active on a module

 

until you cycle the power to the module slot. If you are upgrading

 

multiple modules, download software to all modules first and then cycle

 

the power to these module slots.

 

For software download procedures and instructions about how to cycle

 

power to module slots to activate the new software, see “Downloading

 

Software” next in this chapter.

 

Now that all new modules in your new chassis are operating with

 

compatible software, you can proceed to configure and manage all

 

modules.

 

 

Downloading

This section describes how to download software Release 3.0 and how to

Software

update emergency software download parameters so that the EME can

 

perform an emergency software download if the operational code on a

 

module becomes corrupted.

 

CAUTION: Do not attempt to perform any management tasks while you

 

are downloading software.

Downloading

The following procedure explains how to download software

Release 3.0 Software

Release 3.0 to a switch fabric module or an interface module that is

 

running Release 2.x.x software.

This software download process assumes that:

You have already determined the appropriate software release for your interface module, as well as the compatible software release for the switch fabric modules and management modules. See Table 1 in Chapter 1 for software compatibility requirements.

You are running a TFTP server on a system in your network. This server may support download from any directory on this system or from a single default directory, usually named “tftp” or “tftpboot”.
