Rather than try to explain it here, this link will take you too a great source of the technology.

Redundant Power Supplies
One advanced feature available on high-end machines (especially servers) but also available to the general public for those willing to pay for it, is a redundant power supply. In essence, this is a power supply that actually includes two (or more) units within it, each of which is capable of powering the entire system by itself. If for some reason there is a failure in one of the units, the other one will seamlessly take over to prevent the loss of power to the PC. You can usually even replace the damaged unit without taking the machine down. This is called hot swapping, and is an essential productivity backup for use in servers and other machines used by a number of people.

Can I connect Ethernet to the internet without router

This is possible a few different ways:

-Connect the switch directly to the modem and each computer, then pay your ISP for extra IP addresses for each computer, if they will allow it. Make sure that you secure each computer with proper firewall/security software as it will be directly exposed to the internet. This method typically will not work with ADSL or any ISP that uses a PPPoE connection.
-Install two ethernet cards in one of the computers. Connect the switch to one ethernet card and the modem to the other, then enable internet connection sharing.
-Acquire an older computer with two ethernet cards in it and install free linux based router software such as Smoothwall to create your own homebrew router that has all of the features of the pricy linksys/netgear/etc. routers and then some.

''!!! WARNING: The switch is not usable !!!''

Unfortunately the show stack isn't showing any results other than it is either a hardware or software fault. I am guessing it is a fault with the hardware as the show version in your first post states "interface Ethernet-controller 4 failed POST POST error status : general error occured".

Ethernet-controller 4 is one if the gigabit ports (poss fibre port), so if you have anything attached to those, disconnect and reboot the switch and see what happens. If that doesn't work, you could try reinstalling the IOS, but at a guess I would say its a hardware fault.

Supply problem

If you could state your problem cleary, you might get a better answer.
What can't your switch do?
Does it power on? Switched come with a power adapter that plugs directly into the wall power, then other end into the back of the switch. If it doesn't come on, suspect internal problems
