Yes ! That is all I see here. I've tried it with both Linux and

quite a few folders in fact

Have you found any manuals? Plenty of folders pointing to same "New

If you come in through the front door http://www.oldradios.co.nz/ (with sound
effect of radio tuning across band) look down the left side and you will see
Manuals hyperlink. Click on this and you will get the manuals folders page. At
the top of the screen you will see a pop-up blocked message line. If you
temporarily allow the pop-up it will bring up a donations page. Maybe Greg
Cooney has taken the manuals off-line because he doesn't get any monetary
support to maintain the website.

I sometimes get a little annoyed by all this. The western and central
world looks to bookshops and libraries to study college disciplines. The
eastern and middle eastern world just look to unscrupulous piracy.

Cultural; the Eastern world values copying and mimicry as a form of
worship. The west defines that as plagurism and increasingly theft as it
seeks to lock up knowledge and charge for access. I don't know which is
worse.

credence to his message.

That is why I decided to annoy the crap out of you

Hang on there Keefy, "harmless eccentric", I thought the correct title
was "one of aus.electronics long standing and highly respected
posters"? Please explain when TW's title changed?

Please explain when I ever called TW "one of aus.electronics long
standing and highly respected posters"

Wasn't that how he was described by somone when Trevor Tosspot's Porky
List first went up on aus.electronics. I didn't say you used the
desription, what I said was this dickhead posting his anti-gun drivel
on aus.electronics was considered one of aus.electronics long standing
and highly respected posters, he was not considered a "harmless
eccentric" by those reading his posts there.

So, lets get this clear, anybody expressing an opinion that contradicts
your own opinion is a a dickhead expressing anti-gun drivel thats a
mighty ego that you have there princess. you are always right and
anybody with a contrary opinion is a dickhead, who do you think you are
- the Pope?

If TW isn't a harmless eccentric, please provide proof that he has
caused any sort of harm to gun owners.

Goalpost shift noted, was TW described on aus.electronics as a long
standing and highly respected poster when Trevor Tosspot's Porky List
went up there or not.

These people didn't ming in the least their long standing and highly
respected poster, putting his antigun and antigunowner drivel up, but
got very upset when alternative viewpoint appearred. Remember now?

I am not sure whether they minged is or not, I don't know what minging is..

What is this obsession that you have with TW? Do you fancy him or something?- Hide quoted text -

any, he's repeatadly claimed he "only deals in facts". You seem most

Yes, the current rate of exchange does make purchases from the states

The quick version - a Cisco Ethernet switch, of a type known to have

ATRICS workstations from the network. The remote interlockings then no
longer got instructions and they all went into fail-safe mode. (All Stop).
Just to make it more interesting they had a co-incident real interlocking
failure at Revesby.

My work network (used) to use the very same model of Ethernet switch
Railcorp have a Sydenham. They were all retired - partially as they had a
habit of not turning back on after a power outage and partially as we
wanted an upgrade anyway.
The Cisco 3500 series Ethernet switches have a reputation for power
faults. Bad/cheap capacitors are not lasting the distance.

Caps are shown in Figure 2.

If it is capacitor plague, then the other switches need to be looked at
as well, or we'll quite possibly see the same thing again quite soon.

This would appear to be the case - and it also appears from my
experience that Cisco 4000 series equipment from the same era also
suffered from it in their power supply modules - only being modular, the
power supplies are easily replaced and probably ALL of ours have had
their power supplies replaced - certainly none still in service have the
original power supplies. The capacitors on the actual line card power
regulators have never failed though - they obviously came from a good
factory unlike the modular power supplies. Some computer motherboard
manufactures were not so lucky, with the on board power regulator
capacitors failing.

If it is capacitor plague, then the other switches need to be looked at
as well, or we'll quite possibly see the same thing again quite soon.

These switches are rather expensive, and the Cisco advisory is 'replace
on failure', not 'retire from service'.

Now it comes down to if the MTBF of 15 years is legally enforceable. You
have a premium product that you bought due to it's long MTBF. After the
warranty period, a manufacturing defect means the MTBF figure is not
being met - but who's responsible now ?. The device was fit for purpose
when it was purchased and the first 8 years of it's life.


I imagine now if Railcorp Network engineering see a Cisco 3500 switch
port start to generate a lot of errors, some one will be out to the site
quick smart to pull the power to that device.....

My work network no longer has Cisco 3500 series equipment in any
location were they feed down stream switches and thus a failure could
take out many users. Those left in the network now only feed 'end users'
where any failure will be localised, and the only reason they are still
there at all is money. (lack there of).
The normal failure mode seen with these switches is for them to fail to
restart after a blackout. We have lost dozens to blackouts.

Fitness for purpose doesn't really apply in the usual consumer sense,
since Railcorp isn't a consumer in that sense. But I'd have thought that
a failure to meet the specified MTBF due to a systemic problem was a
breach of contract if the original contract included, whether implied or
otherwise, a statement about the MTBF.

Even with the expense of the switches, given the costs of failure in
this particular case, I'd have thought the cost of replacing either the
switches, their power supply modules, or just their capacitors, would be
justfied, pretty much regardless of cost.

I'd opt for fixing the problem now, and arguing about who carries the
cost later.

I imagine now if Railcorp Network engineering see a Cisco 3500 switch
port start to generate a lot of errors, some one will be out to the site
quick smart to pull the power to that device.....

Which is OK provided the transistion from OK to causing major disruption
is sufficient gradual, and someone is paying attention to failure logs.

If the mean failure time is 15 years and the failure time has a standard
'common garden variety simplest-model' exponential distribution, then
the probability that it will fail in 8 years is about 0.4, and hence the
probability that at least one of four independent units will fail in 8
years is about 1- 0.6**4 which is about 0.87.

So a failure in 8 years is no evidence whatever that the mtbf of 15
years is not met; on the contrary, it is entirely consistent with it.

I can't see Matthew was attempting to draw any inference from the
failure of one out of four in eight years. Indeed the only valid
inference would be that the switches have a non-zero failure rate (or
strictly speaking, that they had a non-zero failure rate before this one
failed, since it could theoretically be the one and only dud).

Instead, the assumption is that the presence of capacitor plague
affected components will prevent the equipment meeting the 15 year MTBF
figure. The question then related to the legal ramfications of that.

Sylvia.

a 100w incandescent) , you will need about 9a @ 12v

If I were you, I'd be fr more concerned about dealing with the heat. Those

You would want to have the fan running too, and absolutely

His party won just *one* seat. What gives the kooky Greens

Kooky idiots - they are getting far too big for their booties.

You should put your bigoted ignorance and unfounded hatred
aside for a moment and listen to what the greens are saying
for a change because they're
talking a lot more sense than that lunatic fringe whacko
mongering Abbott.

What gives Brown more right of reply than Family First or any
of the independents, or the Nationals?

None of *you* whacko lunatic fringe idiots ever tackles Abbott
on the issues - you invariably use demonisation and ad-hom.

Errrr, Abbott has no policies except for scaremongering and sabotage.

Like the NBN?

No, Australia needs the NBN, it's crucial that we have it if we
want to stay competitive in the world market.

Sure. The Coalition can do it for one fifth of the cost - and even *that* is expensive.

They can not provide a future proof NBN as is proposed (and not some
bandaid short term solution that will end up costing much more) for
1/5th of the cost.

You have it arse about. Fixed networks will become a white elephant.

No they wont. They dont share bandwidth, so will always be able to do
better than a wireless network. If fiber wasnt better, we wouldnt have
seen a universal move from wireless to fiber with inter exchange and
international links.

Going forward, we need 'Internet everywhere' not 'where they are up to'.

Yes.

That means fibre backbone and wireless access / last mile.

Nope, it actually means fixed lines for stuff that doesnt move around like houses and wireless for stuff that does
move around.

And you dont save that much by having the last mile wireless anyway,
so you might as well see the benefit of much faster last miles and no
bandwidth sharing with FTTP if you are going to spend that sort of money.

It's academic anyway.

Yes, the gillard govt cant last more than 2.5 years and when the
voters pull the plug on the gillard govt, thats the end of the NBN rollout.

They have overshot their $24m business plan

No they havent yet.

& the Senate will put a stop to the stupidity.

Bet it doesnt. Those that currently have the balance of power in the
Senate come June want the NBN regardless of how much it costs.

Thats true of the HoReps too so the Senate cant put a stop to the NBN even if it wanted to. And what it costs isnt
even in the budget either.

You can also get cfls that work direct off 12V. I have some in a shed on
a property and they are excellent. 3 x 25W units light the 6x6m shed
very nicely. Usually I just run the one light.

That I'm not so sure about. Trevor said it would be easy tho

Baloney.

Fact.

IPTV is a broadcast system, there will be room for several chanels.

Pity Pay TV is HUNDREDS of channels.

And IPTV is only ONE channel per consumer. WiMAX 2

I have my doubts about such a system being retroffited in Sydney

It cant possibly work, there is nothing like enough bandwidth with

There are VASTLY more channels with even tiny cells with WiMAX 2

VoD works with a single channel.

It will depend on the feasibillity and of installing the antenna.

Its got nothing to do with antennas, there isnt enough bandwidth.

Not if the cell size is small enough.

It wont even work even if there is just one customer per cell.

800 houses/km in a suburb with one cell every km is going to work,
