Cisco Mobility Express

Hi All,

Have a Mobility Expres 1832 AP. I just went through set up where I assigned it mgmt IP 192.168.188.100 255.255.255.0 192.168.188.1

It is connected to the switch (2960) and it shows up in CDP, but the IP doesn't show up, and I can't ping it. The device 192.168.188.1 (gateway) has not arrived on site yet so I don't have that in place. The mobility Express AP is flashing red, and I'm wondering if that is because it doesn't have a valid gateway device (since 192.168.188.1 isn't on the network yet), but I would have thought at least I could ping it from the switch (192.168.188.230). SSID is also not showing up in the air. Any thoughts? Wait for the gateway device?
