Re: LAN Console and Cache battery

Battery is not LIKELY to be swollen. However many of the batteries in
Power5 machines are held in place by an ANNOYINGLY stiff piece of plastic.
And yes, sometimes they swell too. Depending on where the battery is
though, it matters little as the power has to be off anyway so the time
added by a swollen battery is very minor.

LAN Console CAN be anywhere after the initial connection is made and the
service tools interface (a.k.a. LAN Console interface) has been stored
along with the default gateway for the network.

That said IBM maintenance agreements require the console be within some
number of feet of the server. Seems like 30 but don't quote me. However
another building is near certain to be too far away. Obviously if you're
doing maintenance and need service tools it's not too efficient to have to
walk 'next door' (or further) while doing maintenance.

There was a meeting earlier this week. Boss knows nothing of the i.

Something over a year ago, the computer configured as LAN console died. A
replacement was procured. At least one call with IBM support to get it to
work. I remember a sequence of 65+21 and options to reset the connection
and allow connection of the new computer. Somewherein there, I seem to
recall reading that the LAN console had to be on the same subnet as the i.
I don't recall if I read it or thought I did.

Boss floated the idea of moving the LAN console from just outside the
computer room to another building. The buildings are network connected.

Am I right that LAN console won't work on a different subnet? This is a
520 stuck on v5r4m0. To be powered off permanently on an undisclosed (to
me) date.

Idea was also floated to discontinue hardware maintenance in January. I
did point out that the cache battery would reach fail not too long after
that, and that at least one person here had to have CE "persuade" old
swollen battery out. I gave them the latest estimated warn and fail days.
Something like 180 and 240 - but that was hours ago and my memory is not
so
good.

So, these questions:
1) Is it more likely the battery just pops out or that it will be
swollen?
2) How long did CE have to work to get swollen battery out?
3) And, finally, is my memory right that LAN console has to be on same
subnet? I can't even remember where I read that tidbit or even if I did.

Thanks
