So we have a couple 2921 routers with the 48 port switch service modules installed. When we plug devices into the switch module ports, the LED indicator lights do not go on right away. This is unlike any Cisco equipment I've dealt with in the past. After several minutes the indicator lights turn on. However when we disconnect the devices from switch module the indicator lights continue to be lit for several minutes after.
Can anyone tell me why this happens on the brand new equipment?
