    I would rather it continued to allow power through on bypass mode then fail completely!

    But my spare part should be here today.

    :S So, some sort of power spike fries your UPS, so it is 'dead', and you'd like the power to just carry on to your servers?

    yes if that case you don't want it to do it, but the fact that it simply failed without any power spikes (other ups didn't report anything plugged into same supply) and they are designed to take power spikes. Its that even when the ups had died you could not put in bypass and boot anything.

    We moaned to APC and got a phonecall from the CEO

    Funnily enough one of my APC UPS' has just done this......6 weeks out of its 2 year warranty!

    Not impressed as I've now got to find more money to replace it (which I hadn't originally put in our budget requirements for this academic year) :-(

    Not really what you expect is it?

    I'm going to look at the AEG ones a bit further for my replacements.

    I've had to RMA 2 and a half HP switches.

    One went fine, one they sent out the wrong replacement due to their web site not listing the correct switch (though since I gave them the serial number the should have noticed this). The last one took a couple of days because there was no replacement stock in the UK.
    I have to ask ..... how do you replace half a switch?

    The only HP Switch i've ever had fail was a little 2626 that wasn't on a UPS, power surge killed it. Only other issue i've ever had was our 4108gl reaching capacity and falling over whenever i tried to make changes, now replaced with an 8206zl though.

    We share it with another school.

    EDIT: We share a campus with another school, it's not like we have the switch Monday to Wednesday and they have it for the rest of the week.

    Many core switches allow you to install various modules, so it's fully customised for your needs. Most switches are typically just 1U in height and only allow a couple of transceivers to be installed.

    Or as is the case with this one you just purchase a chassis and then buy modules to go into said chassis. So to start with it looks like this
    My Core-hp-e5406-zl-switch-chassis_iph3w0443853.jpg then you get modules you want and it looks like this My Core-hp_procurve_e5406zl.jpg

    Aye but the thought of replacing "2 and a half" switches sounded rather amusing in my head, I had this image of one being cut in half

    I'm quite at one with my core switch and it's modules, they hate me and i hate them, it's a mutual disrespect.

    It has been tempting.

    School politics can really take on another level when you've got a Siamese twin.

    EDIT: Especially one that steals your patch cables.
