[c-nsp] smoke and condensation damage to routers

[Scott Granados]

Just to add a little to this, have you seen the condition of some ILEC 
central offices these days?  I remember being in one in Connecticut that had 
standing water.;)
    The point is routers get left in a lot of less than data center quality 
level facilities.  Think of how many 26xx's, hell 25xx, random access 
servers and random odd devices that sit in the back of Quick Stops, food 
courts and the odd war zone here or there that function for not a few months 
but years of uptime.  I would think that if the boxes are reasonably free 
from damage a good cleaning and once over should do the trick.  Before you 
settle with your insurance company make them allow you to leave a month of 
so test period.
