Hello all,

I need help badly. I have an R5SHPN card installed in a 433AH; we have mounted a number of these units on towers to use as sectors. The problem that I'm having is when the temperature drops below 0 degrees Fahrenheit the router becomes unstable, crashes and is typically unreachable via any interface. It is stable in warmer temps and typically will "wake up" when it warms up.

I have installed 433AH's at the same height on the same tower but with R52Hn cards and they have been rock solid which would indicate the problem is with the R5SHPn cards or possibly with the power draw of these cards. The PoE injectors are inside a heated building so they are temperature stable and thus shouldn't be a factor. Does anyone have any suggestions?

Thanks.
