Replace onboard battery-Sup2

[jkaftan]

I have a Sup2 with a dead onboard battery. If I have an extended outage the switch will not boot until I reset the confreg.

However the battery is soldered to the board. Has anyone succussfully replace the onboard battery on a Sup2?

It is more like the battery is tack welded to a metal bracket that is soldered to the board. If I could just buy another battery\bracket combo I might brave re-soldering it to the board.

I've searched the web and can find nothing about it.

Thanks

You aren't going to find anything like that . I assume you have no maintenance contract with cisco ? Replacement of the sup is probably your only bet.

Hack it...I would. Just desolder the battery leads from the board and solder the new battery onto the joints---don't even mess with the brackets. If you can't, then break the solder runs and hardwire a new one in.

You guys must have a lot of leeway to do stuff on your network . We ever tried anything like that we would get fired.

Really? You would get fired? Actually I am planning on hacking it. I was just wondering if I could get the battery bracket combo somewhere.

As for causing major damage...well here is the thing.... I can buy a 6509 with a sup2 and 5 10/100 blades for $2800.

It is so dang cheep I can afford to play with it. If it does not work I will probably just have a Sup2 that does not have a battery which is where I am now.

For what I would pay in maintenance I could buy 3 of these switches every year.

I do have one on maintenance so I will probably send that one in but I have 2 others that are not on maintenance.

As for soldering it can I solder leads right into the battery? Will the battery survive it?

It should---hell, a CMOS battery is a CMOS battery...
Viper---I can't get fired...lol---our company does hardware maintenance for Cisco and a lot of servers---the customer would have a maintenance contract with us, and some have no SmartNet---sometimes it is cheaper this way. I always tell them to back up IOS files and configs, etc. Whomever wrote the rule book got fired a long time ago...lol
An example of a fix I had for Cisco 1750's was to hardwire one of the internal fans to the power pin and a frame ground---the leads on the board would go cold---this is a permanent fix. If there is anything I am actually really good at, it's hacking/rigging things. I started with old Gran Prix transistor radios when I was a kid, moved on to the Timex Sinclair 1000 computer, then AppleII, IIC, IIE, etc.
