SFP Down on FPR 4100

WamuMubiana1384

Level 1

Am trying to configure the Cisco FPR 4112 box. So far Chassis management has been configured and am able to access and manage the box ok either via SSH or Firepower Chassis Manager. The connection to the box via the chassis management port is successful. 

Our box did not come with any SFP modules, so after adding new SFP modules to the box network module, they are visible and are able to enable them in Chassis Manager. However the network led lights are amber and further checks show the operational status as either link-down or Admin-down.

The same SFP modules when plugged on the chassis management network module are working ok. Please see image below:

OK @WamuMubiana1384 I understand.

Have you checked the speed of the interface as specified in FCM? Make sure what is in the chassis manager matches the SFP type (genuine Cisco strongly suggested as noted by @MHM Cisco World  - fxos can be finicky about that) and the connected downstream switch.
