v “Scheduling a system reload” on page 55 - This subsection describes the
procedures required for reloading the system after upgrading the software
images.
Description of the software images required
The functionality within each of the software images required to operate the B48C
and B50C switches is described in Table 11. Because the functions that are most
likely to change are contained within the Multi-Service IronWare image, updates will
usually only require updating the Multi-Service IronWare image. The initial release
of the B48C and B50C supports Multi-Service IronWare version R03.8.00c. For the
latest support information, please visit the Ethernet products support web-site.

Note: The B48C and B50C switches use the same file image for both the boot and

Upgrading the multi-service IronWare software
When performing this upgrade, you will usually only need to upgrade Multi-Service
IronWare image. The Boot and Monitor images will only need to be upgraded as
specifically directed in the relevant release notes.
The steps for this upgrade include the following:
1. Determine the versions of the software images currently installed and running
on the switch.
2. Upgrade the device’s Multi-Service IronWare Image.
3. Reboot the switch.
In most cases, this is all that will be required. If you are directed by the release
notes to upgrade the Monitor or Boot images, use the following procedures:
1. Upgrade the monitor and boot images of the switches.
Use the procedures described in “Upgrading the device’s monitor and boot
images” on page 50.
2. Reboot the switch.
Displaying flash memory and version information
Prior to upgrading the images on a B48C and B50C switch, it is advisable to check
the versions already installed. This allows you to determine which versions need to
be upgraded. It is also useful to check the versions installed immediately after an
upgrade has been done to make sure that you have installed the versions required
in your installation. The following sections describe how to use the
show flash
and
show version commands to display this information.
