One of our clients had DHCP go down when power was lost. Power came back (Servers stayed off) and the Aerohives powered up. The aerohives self-assigned an IP address of 192.168.1.1. When the servers came back up - the aerohive's had the same IP address as the router.
Our client would like to change this behavior so he doesn't have to worry about power cycling all of his Aerohive's after turning on his servers in the event of a power failure.
When windows doesn't get a DHCP address - an APIPA address is assigned. Strange that the Aerohive self-assigns a commonly used router IP when DHCP isn't available.
