sw-update-profile
Specifies the name of a profile to use to control when
software upgrades are attempted (see Chapter 9 for
details on profiles).
The current setting of
sw-update
(in descriptive form) can be seen on the main Status page, adjacent to the
word "Upgrade", as shown in Figure 4.2 (in that example,
sw-update
is set to, or is defaulting to,
factory
).
4.3.4. Manual upgrade
This method is entirely manual, in the sense that the brick itself does not download new software from the
FireBrick servers, and responsibilty for loading breakpoint releases as required lies with the user.
In order to do this, you will first need to download the required software image file (which has the file
extension
.img
) from the FB2700 software downloads website [http://www.firebrick.co.uk/software.php?
PRODUCT=2700] onto your PC.
The next step is the same as you would perform when manually-initiating an Internet-based upgrade i.e. you
should browse to the main Status page, where, if there is new software is available, you will be informed of
this as shown in Figure 4.2.
This step is necessary since the manual upgrade feature currently shares the page used for Internet-based manual
upgrades, which is reached by clicking "Upgrade available" link. After clicking this link, you will find the
manual upgrade method at the bottom of the page, as shown in Figure 4.3 :-

4.4. Boot Process
The FB2700 contains internal Flash memory storage that holds two types of software :-
• main application software (generally referred to as the app)
• a bootloader - runs immediately on power-up, initialises system, and then loads the app
It is possible for only one of these types of software, or neither of them, to be present in the Flash, but when
shipped from the factory the unit will contain a bootloader and the latest factory-release application software.
The FB2700 can store multiple app software images in the Flash, and this is used with an automatic fall-back
mechanism - if a new software image proves unreliable, it is 'demoted', and the unit falls back to running older
software. The
show flash contents
CLI command can be used to see what is stored in the Flash - see
Appendix I.
