The call should read: 
 checkStatus($router->{routerName}, $ssh);

ALso, it is more common (and lazier, and more idiomatic) to code the passed parameters this way: 
sub checkStatus {
    my ($routerName, $ssh) = @_;
   ...

This allows you to add parameters easily, and makes parameter positions visually identifiable without having to examine indexes.
