How to get HP enclosure c7000 information without ssh

In past wef days I was doing some scripting to get the details bout the HP BladeSystem c7000
You can do a lot though the SSH access, but I prefer to get the data without setting up ssh keys or doing some expect scripts. I neede "showAll" output and some nice structured XML file containing the hardware description, MACs, WWIDs, etc...

Maybe it can be useful for some people who wants to do the same - here is the example:

TP-Link TL-WR1043ND and OpenWrt 12.09 with two SSIDs (MultiSSID) - private and guest

I decided to change my home network to match the following "network diagram":

The core part of the design is TP-Link TL-WR1043ND wifi router running OpenWrt with small 16GB USB stick [/dev/sda1] containing ext3 partition with OpenWrt configuration + swap.

There are also 16GB USB stick and 2 thermometers connected using USB <-> Serial connector (bought on eBay):

I'm going to use the last stable version of the OpenWrt firmware: openwrt-ar71xx-generic-tl-wr1043nd-v1-squashfs-sysupgrade.bin

Upgrade the firmware and remove the old configuration:
rm -r /tmp/opkg-lists/
sysctl -w vm.drop_caches=1
sysupgrade -v -n http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-tl-wr1043nd-v1-squashfs-sysupgrade.bin

Here are the notes how way how I configured it.
